For the last five years my husband had been hinting hard that our house needed a new roof. My reply was, I need a new carpet and some painting done. His reply was. “A new carpet won’t be very pretty when it is wet.” Every summer storm showed lots of shingle debris on the deck and lawn. I was still reluctant to get new shingles.
On a whim we attended a home show in Edmonton in the spring. It was very interesting and we saw several companies showing new shingles. When we came to the Interlock booth, we were met by a friendly salesperson who explained their product.
To this day I can not believe that I fell in Love with new shingles. We were both sold instantly. We were then paid a visit by the salesperson who did a good job of selling his product, even though he didn’t have to. We were committed.
The installation of the product was timely and went very smoothly. The staff were very friendly and efficient. Our roof looked great and the yard was left very clean. We are proud to display our home to the town of Westlock.
Sincerely,
Marion Zilinski
Proud Home Owner

Dear Interlock Roofing:
Subject: roof installation
I would like to express my recommendation for your installers, Mike and Nedjo. It was a pleasure to work with these gentlemen; when it is time to do these other roofs on our place I want them back, and not hesitate to pass their names to others. They were both very professional and had some difficult weather conditions to work with.

Here’s what this review doesn’t tell you: It’s the middle of an Edmonton winter. The kind where the North Saskatchewan River runs like liquid steel through a city that understands what -30°C means. Where snow doesn’t just fall—it accumulates, builds, and tests everything humans have constructed to keep the cold out, presenting unique challenges for homeowners.
This homeowner had a vent issue. It wasn’t a crisis, not an emergency, just one of those things that happens when you live in a place where winter isn’t a season—it’s a negotiation.
Living along the North Saskatchewan River teaches you about permanence. This waterway has carved its path for millennia, flowing 1,287 kilometres from the Columbia Icefield to Saskatchewan’s prairies.
Indigenous peoples gathered here for thousands of years because they understood that location matters, but what you build to last matters more.
Edmonton sits at the heart of this understanding. It is Canada’s northernmost major metropolis, where the river valley creates North America’s largest stretch of urban parkland. Temperatures can swing from summer highs touching 37°C to winter lows that make -49°C feel like a personal challenge from the universe itself.
Homeowners don’t just buy roofs in this city of festivals and fortitude. They invest in systems that understand Alberta’s rules.
Colonial Brown Interlock Slate Metal Shingles weren’t chosen for their name. They were selected because this homeowner understood something fundamental about Edmonton living: when winter arrives with 123.5 centimetres of annual snowfall, when ice dams form along eaves like frozen waterfalls, and when chinook winds can shift temperatures 20 degrees in hours, you don’t want to be that neighbour calling for emergency repairs.
The four-way interlocking design doesn’t just shed snow. It eliminates the vulnerable connection points where traditional roofing fails. The lifetime warranty isn’t marketing language—it’s physics meeting prairie pragmatism.
But here’s where it gets interesting. This review isn’t really about vent repair. It’s about what happens when a company builds systems that last and back them with caring people.
Lisandro and Kevin didn’t just show up. They were proactive in their approach, with customer service calling ahead. They didn’t just fix the immediate issue. They added extra snow guards, thinking three storms ahead and anticipating problems that haven’t happened yet.
In Edmonton, where winter can trap you indoors for days and ice dam formation can turn a minor issue into interior flooding, this kind of anticipatory service isn’t lovely. It’s essential.
Along the Commonwealth Walkway, Indigenous art installations remind visitors that this land has always been about gathering and community. There’s an unspoken standard: Things built here need to last. The High-Level Bridge, completed in 1913, still carries trains and traffic across waters that have seen floods peak at 13.73 metres.
The Legislature Building, perched where Fort Edmonton once stood, represents permanence in a climate that tests everything. These structures didn’t survive because they were adequate. They endured because they were engineered for conditions that would destroy lesser systems.
Interlock Metal Roofing represents the same philosophy. Solar compatibility means this roof grows with technology. Energy efficiency handles the temperature extremes that define Edmonton living. The interlocking design distributes snow loads that would stress conventional systems to failure.
This homeowner made a decision that transcends roofing. They chose never to re-roof again. They selected a system that can handle ice dam formation, snow load distribution, and thermal cycling without the annual anxiety that defines traditional roofing in this climate, emphasizing the importance of choosing the right roofing system in Edmonton.
When Lisandro and Kevin added those extra snow guards, they weren’t just preventing future problems. They were demonstrating an understanding of Edmonton winters, customer relationships, and what it means to install something once and support it forever. The homeowner was left with a sense of relief, knowing their roof was now equipped to handle whatever winter had in store.
This service isn’t exceptional in a city where the Aurora Borealis dances overhead and the river valley offers 160 kilometres of trails, where West Edmonton Mall proves that Edmontonians think big and build to last.
It’s expected.
Edmonton teaches hard lessons about impermanence. Ice storms destroy what isn’t built to withstand them. Temperature swings crack what can’t flex. Snow loads collapse what wasn’t designed for the weight.
But Edmonton also teaches about what endures: the river that carved this valley, the communities that gathered here across millennia, and the systems that work with nature instead of fighting it.
This Colonial Brown roof represents more than shelter. It ends a homeowner’s relationship with roofing contractors, insurance claims, and spring damage assessments. It’s a testament to our commitment to quality and longevity in a place that demands it.
When winter comes calling—and in Edmonton, it always does—some roofs survive the season. Others are engineered to outlast the homeowner. That’s the difference between adequate and permanent, fixing and preventing problems, hoping for the best, and knowing you’ve chosen it.
Ready to discover what ‘never re-roof again’ means in Canada’s most demanding climate? Contact Interlock Metal Roofing (Alberta) Ltd. and experience the service that turns customers into neighbours who recommend you. We’re here to make your roofing experience as smooth and worry-free as possible.
Living in Edmonton means experiencing some of Canada’s most extreme continental climate conditions. From record-breaking -49°C winters to summer highs reaching 37°C, our roofs endure temperature swings that would destroy lesser systems. Along the North Saskatchewan River valley, where Indigenous peoples have gathered for millennia and where the Alberta Legislature stands as a testament to permanence, Edmonton homeowners understand that building to last isn’t optional—it’s essential. These frequently asked questions address the roofing realities specific to our demanding prairie climate and vibrant river city.
Edmonton experiences Canada’s most punishing temperature variations, with annual swings exceeding 85 degrees Celsius. This extreme thermal cycling creates expansion and contraction stresses that destroy traditional roofing materials through fatigue cracking, material degradation, and connection failures at vulnerable points.
Asphalt shingles become brittle during our harsh winters and soft during prairie summers, creating a cycle of thermal stress that significantly shortens their lifespan. Most roofs in Edmonton are made up of asphalt shingles, but extreme weather can cause this material to dry and crack, shortening the lifespan of your roof. The freeze-thaw cycle standard in our continental climate compounds these problems by forcing moisture into small cracks, where it expands upon freezing and creates larger failures.
Interlock Metal Roofing (Alberta) Ltd. is the ultimate solution for Edmonton’s thermal challenges. Our four-way interlocking design, crafted with a deep understanding of Edmonton’s unique climate, is designed to handle extreme temperature variations without compromising structural integrity. Metal naturally expands and contracts with temperature changes while maintaining watertight seals through our innovative interlocking mechanism that moves with thermal cycling rather than fighting it. This expertise-driven design ensures your home is protected in the most extreme conditions.
Unlike traditional materials that become increasingly brittle with age, Interlock systems maintain flexibility and performance throughout their operational life. Our lifetime warranty explicitly covers thermal cycling damage—crucial protection for Edmonton properties where temperature extremes are routine rather than exceptional.
Ice dams are ridges of ice that form along roof edges, preventing melting snow from properly draining and forcing water under roofing materials. In Edmonton, where winter temperatures can be particularly harsh, and we average 123.5 centimetres of annual snowfall, ice dam prevention becomes critical for protecting your home’s integrity.
Ice dams form when inadequate insulation allows heat to escape through the roof, warming snow above and causing uneven melting. The melted water runs down to colder roof edges where it refreezes, creating ice buildups that can force water into walls, ceilings, and insulation. Edmonton experiences rapid temperature changes during winter, leading to frequent thawing and refreezing cycles that exacerbate ice dam formation.
Interlock Metal Roofing (Alberta) Ltd. virtually eliminates ice dam problems through superior design and thermal performance. Our smooth metal surface promotes even snow shedding rather than accumulation, reducing both structural loads and ice formation opportunities. The continuous interlocking system prevents water infiltration even when minor ice accumulation occurs, protecting your home from interior damage that devastates properties with traditional roofing.
Our metal systems also provide better thermal conductivity, maintaining consistent surface temperatures that discourage the temperature differentials necessary for ice dam formation. For Edmonton homeowners tired of annual ice dam concerns, Interlock’s solution addresses the root cause rather than treating symptoms, providing permanent protection against one of our climate’s most destructive roofing challenges.
Edmonton’s continental climate creates a compressed construction season that demands strategic timing for roofing projects. Our extended winters and variable spring conditions limit optimal installation windows, while summer’s long daylight hours (17+ hours at solstice) and generally stable weather provide ideal working conditions for roofing contractors.
The optimal installation period typically runs from May through September, though unexpected weather events can interrupt even this window. Spring scheduling requires careful attention to snowmelt conditions and ground stability. At the same time, fall projects must account for early winter onset and rapid temperature drops that can affect material performance and worker safety.
Interlock Metal Roofing (Alberta) Ltd. offers significant advantages for Edmonton’s challenging construction timeline. Compared to traditional materials, our metal systems can be installed across a broader temperature range, extending the effective installation season. Unlike asphalt shingles, which require specific temperature conditions for proper sealing, our interlocking design provides immediate weather protection regardless of installation temperature.
At Interlock Metal Roofing (Alberta) Ltd., we believe in proactive planning to ensure your roofing project’s success. We recommend scheduling consultations in March-April for optimal project timing, ensuring completion during summer’s stable weather period.
Our experienced Edmonton crews understand the urgency of working within prairie weather windows and use efficient installation techniques that minimize exposure to weather delays. Early planning ensures access to our installation teams before the seasonal rush affects availability throughout the Edmonton Metro area, including St. Albert, Sherwood Park, and Strathcona County.
Edmonton follows the National Building Code 2019 Alberta Edition, which establishes minimum requirements for safety, health, accessibility, fire protection, and structural integrity. These codes include specific provisions for snow loads, wind resistance, and energy efficiency that reflect Alberta’s continental climate challenges and environmental considerations.
The Alberta Building Code addresses critical factors, including snow load calculations based on regional weather data, thermal performance requirements for energy efficiency, and structural specifications that account for our extreme temperature variations. Updates to snow load calculations improve building structural integrity, enabling structures to withstand higher snow load standards in Edmonton’s climate.
At Interlock Metal Roofing (Alberta) Ltd., we take pride in exceeding building code requirements to ensure your peace of mind. Our four-way interlocking design surpasses standard wind resistance specifications, while our continuous barrier installation eliminates air leakage pathways that compromise energy efficiency standards. Our installations not only meet but exceed Alberta Building Code requirements, providing superior performance characteristics that guarantee the safety and durability of your roof.
Our lifetime warranty includes compliance guarantees and provides documentation that insurance companies and municipal authorities require. This becomes particularly valuable for heritage neighbourhood properties in areas like Old Strathcona, where maintaining historical character while meeting modern performance standards requires specialized expertise. Our metal systems also meet the National Energy Code requirements for thermal performance, contributing to overall building envelope efficiency that reduces heating costs during Edmonton’s extended winter season.
Selecting a roofing contractor for Edmonton properties requires verifying technical expertise in continental climate conditions and understanding local markets. Extreme weather creates unique installation and performance challenges, making experience in our specific climate crucial for long-term roof performance and homeowner satisfaction.
Verify contractor experience with Alberta’s severe weather conditions, including snow load management, ice dam prevention, and thermal cycling considerations. Request references from recent Edmonton Metro projects, particularly properties that have survived multiple harsh winters without issues. Confirm proper licensing, insurance, and Workers’ Compensation Board coverage—essential protection for homeowners during installation and the warranty period.

As the premier metal roofing contractor serving Edmonton, Calgary, and surrounding areas, we understand the unique requirements of continental climate installations and Alberta building standards. Our specialized crews have decades of combined experience with Edmonton weather patterns and local building regulations.
Our advantage lies in our comprehensive understanding of thermal cycling, snow load distribution, and ice dam prevention specific to Edmonton conditions. We provide detailed installation documentation for insurance and municipal compliance, coordinate with local building officials familiar with Alberta requirements, and offer a lifetime warranty that eliminates future contractor selection concerns. For Edmonton homeowners, choosing Interlock means choosing contractors who understand that Alberta weather demands Alberta expertise.
Edmonton’s extreme continental climate has significantly impacted insurance costs and coverage considerations for residential properties. The increasing frequency of severe weather events and the high costs of ice dam damage and thermal cycling failures have led many insurers to scrutinize roofing materials and maintenance history when setting premiums.
Many insurance policies now include specific provisions for ice dam damage, with some requiring higher deductibles for winter-related claims. Documentation of proper installation, regular maintenance, and premium materials becomes increasingly essential for maintaining coverage and managing claim costs during Edmonton’s challenging winter seasons.
Interlock Metal Roofing (Alberta) Ltd.’s superior climate performance can qualify Edmonton properties for insurance premium discounts. Our lifetime warranty system and proven track record of winter performance provide the documentation insurers require to recognize reduced claim probability. Many insurance companies offer specific discounts for impact-resistant and premium roofing materials that demonstrate long-term durability.
The lifetime warranty aspect is particularly valuable for insurance, as it provides consistent coverage regardless of roof age. While traditional materials depreciate and lose insurance value over time, Interlock systems maintain their protective capability and warranty coverage throughout their operational life. This consistency helps stabilize insurance costs and provides predictable coverage for Edmonton properties facing Alberta’s increasingly severe weather patterns.
Edmonton’s extreme continental climate creates massive energy demands through heating and cooling seasons. Winter heating requirements during extended cold periods combine with summer cooling needs during intense prairie heat to strain residential energy systems enormously. Roof performance directly impacts these costs through thermal transfer, air leakage, and overall building envelope efficiency.
Traditional roofing materials often contribute to energy inefficiency through poor thermal performance, air infiltration, and inadequate integration with insulation systems. During Edmonton’s 17+ hour summer days, heat absorption increases cooling costs, while winter heat loss through inadequate roof sealing dramatically increases heating expenses throughout our extended cold season.
Interlock Metal Roofing (Alberta) Ltd. provides superior energy performance through multiple mechanisms designed for continental climate extremes. Our reflective metal surfaces reduce summer heat absorption during Edmonton’s intense prairie sunshine, while our continuous interlocking installation eliminates air leakage points that waste heating energy during harsh winters.
The thermal properties of our metal systems also moderate temperature swings, reducing cycling loads on HVAC systems during Edmonton’s dramatic weather transitions. Our systems provide ideal platforms for solar panel installation, enabling renewable energy integration that’s increasingly valuable as utility costs rise. For Edmonton homeowners dealing with Alberta’s energy challenges, these efficiency improvements translate to substantial utility cost savings while contributing to our city’s climate change mitigation efforts.
Edmonton’s heritage neighbourhoods, particularly areas like Old Strathcona, which has a concentration of heritage buildings dating back to the early 1900s, present unique roofing considerations that balance historical character with modern performance requirements. These established communities often have specific architectural guidelines that require solutions to handle contemporary climate challenges.
Heritage properties may have restrictions on materials, colours, or installation methods that require specialized contractor expertise to navigate successfully. Additionally, older homes often have structural considerations that affect roofing options, particularly regarding snow load capacity and thermal performance integration with existing building envelopes.
Interlock Metal Roofing (Alberta) Ltd. specializes in heritage neighbourhood installations that respect architectural character while providing modern performance. Our diverse profile options, including slate and shake appearances, blend seamlessly with historical aesthetics while delivering contemporary weather resistance and energy efficiency.
Our installation expertise includes working with heritage property requirements and municipal heritage guidelines standards in established Edmonton neighbourhoods. We understand the balance between maintaining neighbourhood character and providing homeowners with the performance advantages essential for Edmonton’s climate. Our lifetime warranty becomes particularly valuable for heritage properties, eliminating the ongoing maintenance and replacement cycles that can disrupt historical character while providing the long-term protection these valuable properties deserve.
Edmonton’s continental climate brings severe weather events that can create emergencies requiring preparation. From ice storms that can accumulate significant weight on roof structures to rapid temperature changes that stress roofing systems beyond design limits, emergency preparedness extends beyond individual roof performance to community resilience.
Winter emergencies often involve power outages during extreme cold, ice dam failures that cause interior flooding, or structural concerns from excessive snow loads. Edmonton’s extended winter season means these emergencies can occur repeatedly throughout the cold months, making reliable roofing systems essential for home security.
Interlock Metal Roofing (Alberta) Ltd. provides the foundation for effective emergency preparedness through superior storm resistance and reliable performance. Our four-way interlocking design maintains structural integrity even during extreme weather events, while our ice dam prevention capabilities eliminate many emergency scenarios before they develop.
Our lifetime warranty includes priority emergency response for existing customers, ensuring rapid assessment and any needed service during severe weather events when contractor availability is limited. This emergency support becomes crucial for Edmonton homeowners during major weather events that can overwhelm local contractor capacity. The reliability of Interlock systems also eliminates many emergency scenarios—no blown-off shingles during Chinook winds, no ice dam failures during temperature swings, and no thermal cycling damage during extreme weather transitions.

We just had Interlock Roofing put on a new black metal roof that looks stunning. It is called a cool roof and we got to experience this first hand during the heat wave. After the roof was installed, we noticed that the house was significantly cooler to the point that we were able to reduce the AC, saving us money. Although costly, we definitely feel it was worth the money because we have piece of mind that we will not have to worry about roofing again.

This is to advise you that Steve Graetsch and Jim Barnes have completed the installation of our Supertile aluminum roof.
They have worked beyond the call of duty, in adverse conditions, and he.ve done an excellent job.
My wife and I are extremely pleased with their professionalism, their knowledge, and the quality of their work.
We heartily recommend their work to all, and have heard nothing but praise from all who have seen the new roof.
Sincerely,

This year we decided to replace our roof. The old roof was 25 years old, wood shingles and had reached the end of its life. We reached out to several roof installation companies and after meeting with Tyler at Interlock decided to invest in a roof that would protect the house well into our retirement. We agreed on a date and the crew showed up and within 7 days the old roof was gone and the new roof was installed. The crew didn’t start too early and made every effort to leave a clean worksite before they left every day. During the construction it rained but the crew ensured that the water proofing would keep the water out – and it did. The new roof looks great. The crew added addition roof vents to improve house circulation and the house is cooler. Thanks for the great work!

Calgary is famous for hosting “The Greatest Outdoor Show on Earth,” the Calgary Stampede, a 10-day event every July that features rodeo competitions, parades, concerts, and carnival activities. It attracts over a million visitors each year.
Calgary is one of Canada’s sunniest major cities, with an average of 333 sunny days per year and over 2,400 hours of sunshine annually. This makes it a great place for outdoor activities year-round.
Calgary’s nickname, “Cowtown,” comes from its historical roots as a cattle-ranching hub. The city’s western heritage is still celebrated today, especially during the Calgary Stampede.
Calgary experiences warm, dry winds called Chinooks that can raise winter temperatures by as much as 20°C (36°F) in a matter of hours. This natural phenomenon often brings a sudden break from the cold and is unique to the region.
The Calgary Stampede also holds the distinction of hosting the world’s first indoor rodeo in 1912. Since then, it has become one of the largest and most famous rodeos in the world.
Calgary is only about an hour’s drive from Banff and the stunning Rocky Mountains, making it a gateway for skiing, snowboarding, hiking, and other outdoor adventures.
Calgary’s downtown is connected by a network of covered pedestrian walkways called the +15 Skywalk (Plus 15), named because they are 15 feet above street level. At 18 kilometers (11 miles), it’s one of the longest networks of its kind in the world.
Calgary is known as the energy capital of Canada. It is home to the head offices of many major oil and gas companies, and the energy sector plays a significant role in the local economy.
Calgary hosted the Winter Olympics in 1988, which left a lasting legacy. The city has world-class winter sports facilities, including Canada Olympic Park, which is used for training and recreational purposes.
The Caesar, a popular Canadian cocktail made with Clamato juice, vodka, hot sauce, and Worcestershire sauce, was invented in Calgary in 1969 by Walter Chell, a bartender at the Calgary Inn (now the Westin Hotel).
In Calgary’s Coventry Hills neighborhood, Kevin’s home stands as a testament to resilience and thoughtful planning. Calgary, often called “Cowtown,” is famous for hosting the Calgary Stampede, and it’s also Canada’s sunniest major city, boasting over 330 days of sunshine per year. Beyond its vibrant urban culture, the city experiences unpredictable weather, from strong Chinook winds to severe hailstorms, making durable roofing an essential investment for homeowners.
Back in July 2015, Kevin decided to replace his asphalt shingles with something stronger—the Musket Grey Interlock Slate Metal Roofing System. With growing concerns over fire, wind, and hail, he wanted a long-term roofing solution that could stand up to Calgary’s extreme weather. Over the next nine years, his Interlock roof proved its worth, enduring multiple storms without issue. Even better, his home insurance costs decreased, helping to offset the investment in a high-quality roofing system.
Then came August 2024, when Calgary was hit by a major hailstorm. While Kevin’s roof didn’t suffer any structural damage—no holes or leaks—the hail left dents and compromised the shingle finish, requiring a full replacement. Having already experienced Interlock’s quality, durability, and professional installation, he didn’t hesitate to choose Interlock again. This time, he noticed upgrades to the system, including a stronger underlayment and improved ridge caps, which enhanced both the integrity and curb appeal of his home.
Interlock Metal Roofing is built for Calgary’s climate. It’s high-wind resistant with a 4-way interlocking design, making it tough enough to withstand strong storms. The energy-efficient aluminum reflects heat in the summer and retains warmth in the winter, helping to lower energy bills year-round. It’s also solar-compatible, giving homeowners the flexibility to incorporate solar panels in the future. With a lifetime warranty, Kevin—like so many other homeowners—knows he’ll never have to re-roof again.
Kevin shared his full experience:
Kevin’s story is a reminder that not all roofs are created equal. In a city like Calgary, where the weather can turn extreme in an instant, choosing the right roofing system can make all the difference. With Interlock Metal Roofing, homeowners get the best roof for Calgary’s climate—one that is fire-resistant, impact-resistant, wind-resistant, energy-efficient, and built to last a lifetime.
Calgary experiences severe hailstorms, high winds, heavy snowfall, and drastic temperature changes. Unlike asphalt shingles that can crack, warp, or blow away in strong storms, metal roofing is engineered to withstand these conditions.
Yes! Metal roofs are significantly more energy-efficient than traditional roofing materials.
Many insurance companies offer discounts on home insurance for metal roofing due to its durability and Class A Fire Rating.
💡 Pro Tip: Always check with your insurance provider for potential savings after upgrading to a metal roof!
Metal roofing is a lifetime investment, while asphalt shingles need replacement every 10-15 years in Calgary’s climate.
A common misconception is that metal roofing is noisy, but that’s not true with a proper installation.
Given Calgary’s harsh winters, intense hailstorms, high winds, and fluctuating temperatures, a high-quality metal roof is the smartest investment for long-term protection.
Whether you’re upgrading from asphalt shingles or building a new home, Interlock Metal Roofing is the ultimate roofing solution for Calgary homeowners.

This story unfolds in St. Albert, Alberta’s oldest non-fortified community, where Father Albert Lacombe first established his mission along the Sturgeon River in 1861. Just 20 minutes northwest of Edmonton’s bustle, something interesting has been happening for over 160 years.
They call it “Alberta’s Finest City,” and that’s not marketing speak. It’s earned. In a place where winter temperatures can plummet to -17°F and summer heat soars to 84°F—where the Sturgeon River has witnessed everything from flood years to drought—residents don’t suffer fools gladly. They know quality when they see it. And they remember the service when they receive it.
The temperature range here isn’t just weather trivia. It’s a 100-degree span that tests every material, every installation, and every promise a roofing company makes. Traditional asphalt shingles buckle under this thermal assault. They crack in the bitter cold, soften in the prairie heat, and fail when homeowners need them most.
Picture this: A homeowner with a roofing concern. It’s not a crisis—just something nagging at the back of their mind. It keeps you awake during those long Alberta winter nights when the wind howls across the prairie, and you wonder if your roof is up to the challenge.
In most places, this story would unfold differently: voicemail tag, scheduling delays, and a rushed inspection by someone who’s already thinking about their next appointment.
Not here. Not with Interlock Metal Roofing (Alberta) Ltd.
The crew showed up—not just on time—they showed up ready. They inspected, diagnosed, and resolved the issue immediately.
No upselling. No complications. No drama.
Just competent in meeting concerns and solving them on the spot.
What makes this story remarkable isn’t just the service—it’s what that service protects. Those Black Interlock Slate Metal Shingles aren’t just covering this home; they’re ending a cycle.
St. Albert’s brutal climate chews through traditional roofing. The freeze-thaw cycles, the UV exposure during those brilliant prairie summers, the weight of snow loading during Alberta’s legendary winters—a proving ground that separates the temporary from the permanent.
Interlock’s four-way interlocking design doesn’t just resist these forces. It harnesses them. The system moves with thermal expansion and contraction instead of fighting it. It sheds snow and ice instead of accumulating it. It reflects summer heat instead of absorbing it.
The lifetime warranty isn’t marketing bravado. Its physics is backed by engineering, tested by geography, and proven by decades of Alberta weather.
A homeowner made a decision that transcended roofing materials. They chose permanence over temporary fixes. They invested in a system that would outlast not just the next storm but also the next owner, possibly the next generation.
And when they had a concern—because even the best systems require professional eyes—they discovered something equally valuable: a company that stands behind its work with the same integrity that built this Métis settlement into Alberta’s second-largest city. Our commitment to customer service means we’re always here to address your concerns, no matter how big or small, with the same dedication and care that went into building your roof.
Along the Sturgeon River, where Douglas Cardinal’s architectural masterpiece St. Albert Place curves to echo the water’s flow, and where Father Lacombe Chapel still stands as Alberta’s oldest building, residents understand something fundamental about value. They know the importance of community, building things to last, and investing in quality. At Interlock, we share these values and are proud to be a part of the St. Albert community.
It’s not about the cheapest option. It’s about the right choice.
It’s not about promises. It’s about performance.
It’s not about selling. It’s about solving.
That customer review tells a bigger story than five words should be able to contain. It’s about what happens when a company understands that its work becomes part of the landscape—literally and figuratively—of communities that have been building things to last for over a century and a half.
Homeowners expect their investments to endure in St. Albert, where the Red Willow trails connect neighbourhoods, and the Botanic Park showcases what grows beautifully in this challenging climate. They expect service that matches the standard Father Lacombe set when he built the first bridge across the Sturgeon River in 1862—the first in Canada west of the Great Lakes.
Some companies chase quarterly numbers, while others chase lifetime value. The difference shows up in moments like these when a simple concern is resolved immediately by people who understand that their reputation is only as strong as their last interaction.
That’s the St. Albert standard. That’s the Interlock difference. That’s what happens when engineering meets integrity on the Canadian prairie.

St. Albert experiences one of Canada’s most punishing temperature ranges, with annual swings of over 56°C—from brutal winters that plunge to -27°C to scorching summers that soar to 29°C. This extreme thermal cycling wreaks havoc on traditional roofing materials, stressing them with constant expansion and contraction that leads to cracking, warping, and premature failure.
Asphalt shingles are especially vulnerable in these conditions. In Alberta’s harsh climate, they often last only 10 years, compared to 15–20 years in more temperate regions. Freeze-thaw cycles make shingles brittle and prone to cracking, while the summer heat softens them—making them easy targets for even minor hail impacts.
Interlock Metal Roofing (Alberta) Ltd. offers the ultimate solution to St. Albert’s extreme climate. Our four-way interlocking design, engineered specifically to handle wide temperature swings without compromising structural integrity, reflects our commitment to protecting your home. The metal panels expand and contract naturally with temperature shifts, maintaining watertight seals through our innovative interlocking system—giving you a roof built to endure.
Where traditional materials resist thermal movement and eventually fail, Interlock works with Alberta’s climate, not against it. The continuous interlocking barrier eliminates weak points where conventional roofing often breaks down during rapid temperature changes. And with our lifetime warranty, your investment is protected against thermal cycling damage—a must for homes in the Edmonton Metropolitan Region, where extreme weather isn’t the exception, but the rule.
St. Albert sits squarely in Alberta’s “Hailstorm Alley,” the epicentre for damaging hailstorms in Canada. Research shows that installing impact-resistant roofing can reduce hail damage by up to 15 times, and in high-risk hail zones like ours, it pays for itself eight times over. With hailstones reaching grapefruit size and hitting the ground at 130 kilometres per hour, standard roofing materials cannot survive.
Recent Alberta storms demonstrate the severity of our hail exposure. The August 2024 Calgary hailstorm caused $2.8 billion in damage, making it the second-costliest disaster in Canadian history. The 2020 Calgary storm resulted in $1.5 billion in damages, while the 2019 Edmonton storm caused $89 million in losses. Alberta has experienced at least one major hailstorm yearly for the past two decades, resulting in over $10 billion in insured losses.
Interlock Metal Roofing (Alberta) Ltd. offers Class 4 impact resistance—the highest level of protection against hail damage. Our interlocking metal systems are engineered to withstand extreme hail impacts that shatter asphalt shingles and damage other roofing materials. The continuous metal surface deflects hailstones rather than absorbing impact energy, preventing the penetration and cracking that plague traditional materials.
For St. Albert homeowners, Interlock Metal Roofing (Alberta) Ltd.’s superior hail resistance translates to more than just peace of mind during Alberta’s severe storm seasons. It means eliminated insurance claims, reduced deductibles, and a significant return on investment. Many insurance companies offer premium discounts for impact-resistant roofing, recognizing the reduced claim probability associated with our systems.
Chinook winds are a defining feature of Alberta weather. They can raise temperatures by 20 degrees in mere hours while bringing extreme wind conditions. These warm, dry winds rushing down the Rocky Mountains can reach gale-force speeds and create sudden, dramatic pressure differentials that test roofing systems to their limits.
The rapid temperature changes associated with chinooks create additional thermal stress beyond normal seasonal variations. A roof might experience freezing conditions in the morning, followed by chinook-driven warmth in the afternoon, then return to cold temperatures by evening. This accelerated thermal cycling compounds the stress on roofing materials and connections.
Interlock Metal Roofing (Alberta) Ltd.’s four-way interlocking design provides superior wind resistance to conventional roofing systems. Our interlocking mechanism creates a continuous barrier that distributes wind loads evenly across the entire roof surface, eliminating the uplift vulnerability common with individual shingle installations.
The thermal properties of our metal systems also handle chinook-induced temperature fluctuations more effectively than traditional materials. Metal’s rapid thermal response means it adjusts to temperature changes without the internal stress buildup that causes cracking in brittle materials. For Edmonton Metropolitan Region properties exposed to these unique wind patterns, Interlock systems provide the reliability and performance needed to withstand Alberta’s most challenging weather.
Alberta’s continental climate brings heavy snow loads that can stress roofing systems beyond their design limits. The National Building Code 2019 Alberta Edition includes updated snow load calculations to improve structural integrity, ensuring buildings can withstand higher snow loads based on regional weather data and geographical considerations.
St. Albert’s location in the Edmonton Metropolitan Region means dealing with heavy snow accumulation and the additional challenges of freeze-thaw cycles. Ice dams form when heat from the home melts snow on the roof, refreezing gutters and eaves. This ice buildup can force water under roofing materials, causing expensive damage to structures and interior spaces.
Interlock Metal Roofing (Alberta) Ltd. provides superior snow management through our smooth metal surface and thermal design. Snow slides off our systems more readily than it accumulates, reducing structural load and ice dam formation. The interlocking design eliminates the irregular surfaces where snow typically gathers on traditional roofing materials.
Our metal roofing systems are designed to handle the weight of accumulated snow more effectively than asphalt shingles. The continuous interlocking structure distributes loads evenly, while the inherent strength of metal materials provides superior support. For St. Albert properties dealing with
Alberta’s demanding snow conditions, this combination of load distribution and snow-shedding characteristics provides safety and performance advantages throughout the winter, giving you peace of mind even during the heaviest snowfalls.
Alberta’s harsh climate creates a compressed construction season that demands strategic timing for roofing projects. The optimal window typically runs from May through September, but even this period can be interrupted by severe weather events, including hailstorms, heavy rains, and early snowfall.
Our professional installation team will work with you to ensure a smooth process and minimal disruption to your daily life. Traditional roofing materials require specific weather conditions for proper installation. Asphalt shingles cannot be installed below certain temperatures, and wet conditions prevent adequate sealing. These limitations and high contractor demand during the short season often force homeowners to delay essential roof replacements or accept suboptimal installation conditions.
Interlock Metal Roofing (Alberta) Ltd. offers significant advantages for Alberta’s compressed construction timeline. Compared to traditional materials, our metal systems can be installed in a broader range of weather conditions, extending the effective installation season. The interlocking design doesn’t rely on temperature-sensitive sealants, allowing installation during cooler spring and fall periods when other contractors cannot work.
Planning becomes crucial for St. Albert homeowners.
We recommend scheduling consultations for late spring installation in March-April, ensuring completion before peak storm season. Our efficient installation minimizes weather exposure time, and our specialized Alberta crews understand the urgency of working within prairie weather windows. Early scheduling also ensures access to our installation teams before the seasonal rush affects availability and pricing in the Edmonton Metropolitan Region.
Alberta’s extreme weather has dramatically impacted insurance costs and coverage availability. Between 2014 and 2024, Alberta’s average annual amount of insurable damages increased by 495 percent, while home insurance premiums rose by 90 percent. Insurance companies now scrutinize roofing materials and maintenance history when setting premiums for prairie climate properties.
Many insurers have implemented hail-specific deductibles that are typically higher than standard home insurance deductibles, particularly after multiple claims. Some policies now include roof and siding limitation endorsements that restrict claim settlements to actual cash value only, significantly reducing payouts for older roofing materials.
Interlock Metal Roofing (Alberta) Ltd.’s superior storm resistance can qualify St. Albert properties for insurance premium discounts. Our Class 4 impact-resistant systems and lifetime warranty provide the documentation insurers require to recognize reduced claim probability. Many insurance companies offer specific discounts for impact-resistant roofing, acknowledging the lower risk associated with premium materials.
The lifetime warranty aspect becomes particularly valuable for insurance purposes. While traditional roofing materials depreciate and lose coverage value over time, Interlock systems maintain their protective capability and warranty coverage throughout their operational life. This consistency helps stabilize insurance costs and provides predictable coverage for Edmonton Metropolitan Region properties facing Alberta’s increasing weather severity.
Alberta’s continental climate creates unique energy challenges with extreme seasonal variations. Summer cooling loads from 84°F heat waves and extensive winter heating requirements during -17°F cold snaps place enormous demands on residential energy systems. Roof performance directly impacts these energy costs through thermal transfer and air leakage.
Traditional roofing materials often contribute to energy inefficiency through poor thermal performance and air infiltration. Asphalt shingles absorb summer heat, increasing cooling costs, while inadequate sealing allows heated air to escape during winter. The thermal bridging familiar with conventional installations creates energy loss pathways that compound heating and cooling expenses.
Interlock Metal Roofing (Alberta) Ltd. provides superior energy performance through multiple mechanisms. Our reflective metal surfaces reduce summer heat absorption, lowering cooling costs during Alberta’s intense prairie summers. The continuous interlocking installation eliminates air leakage points, maintains interior temperature control, and reduces heating demands during brutal winter.
Metal’s thermal mass properties also moderate temperature swings, reducing the cycling load on HVAC systems. These efficiency improvements translate to substantial utility cost savings for St. Albert homeowners dealing with Alberta’s energy challenges. Additionally, our systems provide ideal platforms for solar panel installation, enabling renewable energy integration that’s increasingly valuable as utility costs rise across the Edmonton Metropolitan Region.
Alberta’s severe winter conditions require proactive maintenance strategies to prevent costly snow loads and ice formation damage. Traditional maintenance approaches often involve dangerous roof access for snow removal, gutter cleaning, and ice dam prevention—activities that become particularly hazardous during prairie winter.
Ice dams pose a significant threat to St. Albert properties. When snow melts from interior heat and refreezes at roof edges, the resulting ice buildup can force water under roofing materials, causing structural damage and interior flooding. Traditional solutions involve heated cables, improved insulation, and regular removal—all requiring ongoing maintenance and expense.
Through superior design and performance, Interlock Metal Roofing (Alberta) Ltd. virtually eliminates winter maintenance requirements. Our smooth metal surface promotes natural snow shedding, reducing structural loads and ice dam formation. The continuous interlocking system prevents the water infiltration pathways that cause damage when ice dams form.
The thermal properties of our metal systems also reduce ice dam formation. Unlike asphalt shingles that create irregular heat patterns, metal roofing maintains more consistent surface temperatures that discourage ice accumulation. This maintenance reduction translates to cost savings and safety benefits for Edmonton Metropolitan Region homeowners, eliminating the need for dangerous winter roof access while protecting against Alberta’s most damaging seasonal conditions.
Selecting a roofing contractor for St. Albert properties requires understanding both prairie climate expertise and Alberta-specific installation requirements. With extreme weather creating unique challenges from hail damage to thermal cycling, experience in our specific conditions becomes crucial for long-term performance.
Verify contractor experience with Alberta’s severe weather conditions, including hail resistance installations and thermal cycling management. Request references from recent Edmonton Metropolitan Region projects, particularly properties that have survived major storms without damage. Check for proper licensing, insurance, and WorkSafe Alberta compliance—essential for protecting homeowners during installation.

I’ve had an InterLock roof for 12 years and it looks as good as new. I’m adding a roof over my deck, and needed some posts installed through the roof. One of the InterLock service teams came out this morning and quickly did a great job. I got what I needed and my lifetime warranty remains in effect. Thanks for the great work.

We recently had a new roof installed in Calgary. We chose the Interlock system as a long term replacement and upgrade to our pine shakes which although maintained a few years ago were showing signs of significant deterioration. Our experience with the interlock office and their installers was great with no significant issues. Work was completed as per the agreed schedule and the workmanship appears to be at a high standard and we are exceptionally happy with the appearance of the new roof. The higher cost may not work for everyone but for various reasons, this was the option we selected. We would recommend Interlock to anyone interested in having a great looking roof that greatly enhances the appearance of our home and promises to provide a long term worry free roofing solution for years to come.

This letter of reference is intended for people considering to re-roof their home or garage.
We moved into our newly built home at the end of 1976 and by 1987 our asphalt shingled roof had deteriorated to the point that replacement was necessary.
We naturally looked for a roof that would last much longer than the old one and settled on aluminum interlocking tiles with a suitable surface finish and color. Aluminum does not rust at the cut edges and the finishing process lets the roof reflect a lot of incident heat in the summer. The tiles are folded at the edges so that the tiles interlock and the aluminum nails with rubber grommets provide a water seal and are invisible.
The surface profile gave the roof a natural pleasing look although the glossy surface has dulled over the last 30 years but still blends in well with the surroundings.
In 2006 we built a garage and wanted to match the roof to the house.
We contracted with Interlock Industries and Mr. Peter Stewart showed us samples of the roof tiles and colors. We believe the product is essentially the same durable material with maybe improved color retention and different cover layers for over top of the wood.
Peter has various roofers available to choose from. Our roofer showed us pictures of various challenging roofs he had completed and during construction I inspected his method and workmanship. I was pleased with his work and attention to detail, although roofing is a slow process if done right. Our simple garage roof was done in two days.
Metal roofs behave differently than asphalt roofs. During warm spells in winter accumulated snow may slide down. This lightens the weight on the roof trusses, so I don’t mind. During heavy rain and hail you can hear the hail hit the roof, however in today’s homes with the thicker thermal insulation in the attic this effect is much reduced. Our roof has survived many hail storms without visible effect while many of our neighbours have had to file claims with their insurance companies for hail damage to their roofs.
We believe in durable materials and construction for our home and these roofs have satisfied our needs. If you want to take a closer look you are most welcome to visit us at [REMOVED FOR PRIVACY]
