Calgary, AB Aluminum Shingle Review — Interlock Install 2015, Replaced 2024

Calgary, AB

TL;DR: Calgary Review Summary

Roofing installation in Calgary: the homeowner replaced asphalt shingles with a metal roof in July 2015 to address fire, wind, and hail concerns. The metal roof performed well for nine years and led to a slight insurance reduction, but a major hail event in August 2024 caused dents and damage to the shingle finish (no holes) requiring a complete replacement; they returned to Interlock and noted improved underlayment and wider, sturdier ridge caps that enhanced the home’s look and integrity.
Kevin W.

“When we decided to have our asphalt shingles replaced back in July of 2015 we decided to pursue a metal roofing design to assist in coping with increased fire, wind and hail concerns.
Since the original install we have experienced some hail and wind events and our roof appeared to be in good standing over the past nine years

We did experience a slight reduction in our home insurance due to the installation of our metal roof (help offset extra cost of this product)
However in August 2024 the City of Calgary experienced a major hail event we required a complete replacement of the roofing system (no holes just dents and damage to shingle finish)

We decided to return back to Interlock based on past experience with their knowledgeable sale and installation staff
We were happy to see Interlock’s commitment to continuous improvement with respect to a better underlayment system (wider, sturdier ridge caps) that improve the look and integrity of our home. “

Top 10 Metal Roofing FAQs for Homeowners in Calgary

Homeowners researching metal roofing in Calgary often have several important questions before replacing their roof. Many people want to understand how metal roofing compares to traditional materials like asphalt shingles in terms of lifespan, durability, cost, and long-term value. Roofing decisions can also be influenced by local weather conditions. Homes in Calgary may experience environmental factors such as rain, wind, snow, heat, fire, or seasonal storms that can impact roof performance over time. The following frequently asked questions help explain what homeowners should know when evaluating metal roofing and why many people choose durable roofing systems designed for long-term protection.

Metal roofs commonly last at least 50–75+ years, while asphalt shingles typically have shorter lifespans (often around 20–30 years depending on quality and maintenance). Calgary’s roof performance is shaped by two local factors: frequent freeze–thaw cycles (Calgary averages many freeze–thaw days, which stress materials and accelerate shingle breakdown). Regular severe hailstorms and strong winds also bruise asphalt granules, dent weaker materials and shorten service life, making metal a more resilient choice in this climate. Homeowners often choose durable roofing systems to minimise repairs, resist hail and thermal cycling, and protect against leaks. Interlock Metal Roofing systems use heavy-gauge aluminium and a lifetime limited 50-year transferable warranty designed for long-term protection.
In Calgary, AB, a metal roof typically costs more upfront than asphalt shingles, but price varies widely. Factors that determine cost include roof area, pitch/slope, complexity (hips, valleys, dormers), tear‑off of old material, flashing, skylights, and local labour rates. Calgary’s construction environment—seasonal access, permit requirements, insulation and ventilation standards, and installer availability—also affects pricing. Many homeowners compare options by lifetime value rather than initial price: metal roofs resist rot, wind and ice damage, shed snow, and often need fewer repairs, which can lower long‑term costs and replacement frequency. A durable roofing system can reduce future repair and replacement expenditures and improve resale appeal. Interlock Metal Roofing emphasises long‑term ownership value and performance rather than competing as a low‑cost option, focusing on durability, warranty support and total cost of ownership.
Short answer: yes—many Calgary homeowners find metal roofing worth the extra upfront cost if they prioritise durability and long-term protection. Lifespan: metal commonly lasts 40–70 years versus 15–30 years for asphalt shingles. Maintenance: metal is lower‑maintenance (occasional inspections, fastener checks); shingles need more frequent spot repairs and replacement after major storms. Durability: metal resists freeze–thaw cycling, shedding snow and standing up to temperature swings; large hail is a local hazard that can damage both materials, though modern coated metal and thicker profiles perform better in repeated events. Long‑term value: higher upfront cost for metal but lower life‑cycle costs and better resale appeal for owners who plan to stay long term. Interlock Metal Roofing appeals to homeowners seeking long‑term performance and architectural curb appeal because it combines durable interlocking panels with a finished look built to perform in Calgary’s climate.
In Calgary, AB, this is a common myth. Modern residential metal roofs installed over solid decking do not sound like barn roofs during rain. A residential metal roof’s perceived noise depends on the roof assembly — insulation, attic space and underlayment all absorb sound — so properly insulated, ventilated assemblies sound much like shingles or tiles. Installation quality matters: secure fastening, solid sheathing and correct underlayments reduce vibration and noise. In most cases a properly installed residential metal roof is audibly similar to other roofing materials during rain. Interlock Metal Roofing systems are installed as complete roofing systems specifically designed for residential homes, with components chosen to control weatherproofing and sound performance.
Metal roofing can be energy efficient in Calgary. Its reflective surface reduces solar heat gain on sunny summer days, lowering cooling loads, while lighter‑coloured finishes increase reflectivity. Overall energy performance also depends on the complete roof assembly: proper insulation levels, air‑sealing and ventilation control heat flow and moisture year‑round. Calgary’s climate—cold winters with substantial heating demand and sunny summers—means benefits vary by season and by roof design. Homeowners researching roof replacement often prioritise energy efficiency to lower heating and cooling costs, improve comfort, extend roof and attic component life, and meet long‑term performance goals. When assessing options, consider finish, insulation, attic ventilation and installation quality. Interlock Metal Roofing systems are designed to support long‑term home performance through durable materials and systems‑level design.
Q: How does metal roofing perform in Calgary’s severe weather? Calgary regularly faces large hail, intense convective storms and strong Chinook winds that produce rapid freeze–thaw cycles and high gusts; these events can cause significant roof damage and insured losses in the region. Metal roofs can perform very well in wind, shed snow efficiently and resist impact better than many materials when the system is specified for appropriate gauge, profile and fastening. Performance depends on roofing system design, installation quality and material durability (coating, gauge, backing). Homeowners consider weather resilience to reduce maintenance, limit hail/wind damage and lower insurance risk. Interlock Metal Roofing systems are engineered for durability, hail protection and wind resistance; ask for impact-test data and local installer references.
Metal roofing performance depends on the metal chosen; steel, zinc, copper and aluminium each show different corrosion behaviours. Some materials — notably aluminium and properly coated steels — are more resistant to rust and salt- or moisture-driven corrosion, while untreated steel will oxidise over time. Aluminium performs particularly well in wet or coastal environments because it naturally forms a protective oxide layer. Homeowners should consider corrosion resistance when selecting roofing to avoid leaks, premature replacement, higher repair costs and reduced energy losses, especially with Calgary’s seasonal freeze–thaw cycles. Interlock Metal Roofing systems use aluminium construction designed for strong corrosion resistance and are protected by the Alunar Coating System for extra protection, improving longevity and reducing maintenance.
Metal roofing is generally considered a durable, low‑maintenance option for Calgary homes, resisting rot, insects and many weather effects. No roof is completely maintenance‑free: homeowners should inspect roofs periodically—seasonally and after major storms—to spot issues early. Check for accumulated debris, blocked gutters, damaged flashing, and around penetrations such as vents, chimneys and skylights. Look for loose fasteners, sealant deterioration, corrosion or displaced panels. Weather events (heavy snow, ice, wind or hail) and seasonal debris from trees can affect performance and should prompt an inspection. Routine, simple maintenance and timely repairs keep warranties valid and extend service life, making metal roofing a practical long‑term choice in Alberta’s climate.
Yes — in Calgary a well‑chosen metal roof can increase a home’s value. Buyers often prioritise durable, low‑maintenance roofs that reduce future repair costs, and premium roofing materials boost curb appeal. A metal roof’s long lifespan and proven weather resistance instil buyer confidence, particularly in markets concerned with winter snow and freeze–thaw cycles. That said, architectural style matters: a roof that complements the design of nearby houses and neighbourhood character will be more appealing than one that looks out of place. Interlock Metal Roofing systems offer multiple architectural profiles — slate, cedar shingle, Mediterranean tile, shake and standing seam — and are available in heavy‑gauge aluminium and solid copper, allowing you to match aesthetics while delivering longevity and low upkeep.
Yes — Interlock Metal Roofing systems are compatible with solar panels when fitted with custom solar brackets installed by Interlock Metal Roofing (Alberta) Ltd. Calgary’s frequent hail and Chinook winds, plus strong freeze–thaw cycles and high UV exposure, influence roof and mounting durability and should inform material choice. Long-lived roofing materials are preferred when adding solar because panels often outlast roofs; replacing a short-lived roof after installation multiplies cost and labour. When comparing roofing materials here, consider roof lifespan and future solar plans before replacing or re-roofing—Interlock systems are solar compatible and designed to support secure solar mounting solutions and coordinated brackets, flashings and warranties.

I’ve had my interlock roof for 14 yrs and have had no issues with it until this last winter. We had heavier than normal snow and a lot of freeze thaw conditions. Several of the snow deflectors were pushed forward and lifted some of the roof. I emailed Dave and Tyler and repairs were made quickly . You can’t tell there was any concerns at all.

Metal Shingle Roof Review in Sudbury, ON (Interlock - Installed 2017)

Review: April 25, 2026

Completion: June 7, 2018

We had our roof replaced in 2017 with an aluminum roof by Interlock Metal Roofing. We live on the lake, and prior to the replacement, we were spending thousands of dollars every year because shingles would fly off in the wind.

We haven’t had any issues in the past 7 years. Our experience with Interlock Metal Roofing was excellent — they were very professional and did a beautiful job, even though our roof is quite high and challenging.

Our roof still looks beautiful, and we haven’t had to worry about it at all in the past 9 years.

Corvallis, OR Metal Shingle Roof Review — Interlock (Installed 2017)

Review: April 24, 2026

Completion: November 9, 2017

I love my Interlock roof! No more climbing up to clean it, and no more gritty debris falling into my garden after a few years. It looks fantastic and performs exactly as it should.

The installers were excellent—knowledgeable, detail-oriented, and personable. Ivan is a gem! He handled a small flashing addition efficiently and cleaned the entire roof with a blower in no time.

After almost ten years, it’s still the only roof I would choose.

Interlock Metal Roof Review - Ramara, ON (Installed 2019)

Review: April 23, 2026

Completion: April 23, 2026

We are so happy with our interlock roof from Bruce. We had shopped around because we live on the lake with strong winds and we wanted a quality, long lasting product. Our roof has never changed colour and looks just as good now as the day it was installed. We also love the lifetime transferable warranty. We also love that it is made in Canada so there are no tariffs. Bruce was our sales person. He came right away, explained everything to us. We made the right decision not choosing shingles because of the environment and quality of the product. This was an affordable investment that was worth it. The crew was professional in every aspect. If I move, I will definitely be contacting Bruce again for another interlock roof.

Portland, OR Metal Shingles Review — Safety Anchors Installed 2019

Review: April 20, 2026

Completion: June 20, 2019

We’ve had our roof for about 7 years and have been very pleased with it. Recently, I scheduled gutter cleaning which was complicated by a run of wet weather which makes the roof very slippery. The gutter contractor asked if we had ever considered installing safety anchors. I didn’t know there was such a thing. I called Interlock and Ivan came by to take a look. He quickly determined appropriate locations for the anchors that the gutter cleaners could clip their safety harnesses to and showed me an example of the anchor itself. He also offered to paint them black to make them more inconspicuous on our dark roof. He returned about a week later for the install and afterwards showed us pictures of the anchors from the roof and pointed them out from the ground. Overall very professional, prompt, excellent service.

Interlock Metal Shingle Roof Review in Bay View, WI (Installed 2009)

Review: April 16, 2026

Completion: February 20, 2009

I had Interlock put on a beautiful red slate roof 17 years ago.The roof still looks beautiful. 5 years ago, I had them also re-roof my garage with the same type of slate. The roofs look gorgeous and I have no maintenance whatsoever.I get complements all the time. The guy whom I contracted with was named "Tim' but has since died. He was a really nice guy. Back in 2009, the roof was much cheaper. ( I actually paid more for the garage 5 years ago!) I am extremely happy with the roofs. The guys did a wonderful job, replacing rotted boards where necessary. They also told me about very cheap gutters I could buy at Menards instead of those ridiculously - priced "special" gutter systems. I bought them and they placed them on my buildings.This home will go to my daughter one day; I do not want her to have to lift a finger. Note that I had an asphalt roof previously. It lasted only 12 years. The shingles curled up under the sun and cracked. They looked terrible. I can honestly say that these metals roofs by Interlock are very much worth what you pay for them. They will last a lifetime with almost no maintenance. Instead of replacing a roof every 15 years and paying lots for asphalt or fiberglass, their metal roofs last very long and you will never have to re- roof again.

Interlock Metal Roofing Review in Saint Paul, AB — 50-Year Warranty (Installed 2025)

Review: April 15, 2026

Completion: August 31, 2025

We recently installed a new Interlock Roofing System, and we couldn’t be happier with the decision. Knowing it’s backed by a limited lifetime, non-prorated, fully transferable 50-year warranty gives us real peace of mind—it truly feels like a smart long-term investment. Mr. Yorman and his crew were outstanding from start to finish. Their commitment to customer service is second to none. They showed up exactly when they said they would and worked diligently until the job was completed. The finished product looks fantastic, and the cleanup was so thorough that our property actually looked better than before they arrived. A special mention to Tyler, who did an excellent job walking us through the benefits and helping us feel confident in choosing this system. Overall, a great experience and highly recommended!

I recently had my 25 year old asphalt roof replaced with an Interlock Metal roof. I'm so very happy with my decision. In fact, best decision ever to have Interlock Industries install.

Aurora, ON Metal Roofing Review — Interlock Installation (2016)

Review: April 13, 2026

Completion: May 3, 2016

We moved into our new house in 1984. Our new house came with new 25 year shingles. In 2004, 20 years later we noticed that our roof shingles needed to be redone. Now, back in 1984 they used asbestos in the roof shingles and although at the time they said they were 25 year shingles, we were still happy to get 20 years out of them. So, in 2004 we got a quote and had the roof re-shingled. We paid extra for the 25 year shingles as we had such a good result with the original shingles. In 2016 (i.e. 12 years later) my neighbour told us that our shingles on the south side of the house were cracked with rolled up edges and needed to be replaced. (We can't see the south roof of our house unless we are visiting the neighbours.) The shingles on the north side were still ok, but since you can't really shingle half a roof we knew that we had to have the whole roof done...after just 12 years. We were a little upset about this and decided to go to the National Home Show in Toronto to look at alternatives. We met Tom Watson at the Interlock Metal Roofing booth and he took a lot of time and explained the complete roofing system to us. We liked what we saw and what was explained to us and we arranged to have a home visit from Interlock and to give us a quote. The metal roof was certainly a lot more expensive than a regular asphalt shingle roof, but we decided to get the metal roof anyways because we did not want the hassle of having to re-shingle every 10 or 11 years...and there are also some other unforeseen benefits detailed below that we did not know about at the time. The metal roof comes with a Lifetime Limited Warranty, 50 year transferable, not prorated so even though more expensive it adds value to lyour home because if in the future you are looking to sell, the buyer knows he won't have any roof problems for the 50 year life of the roof. Your roof becomes an asset instead of a liability. The installation happened over 4-5 days. I paid a lot of attention to what they were doing and how they were doing it. The roof vents were removed. These are the same roof vents that raccoons like to rip off for access to your attic, so that potential problem went away. A ridge vent (google it) was installed on the top of the roof and it is low profile and fits in so you would not know that it is there. Raccoons have been known to chew a hole in asphalt shingles and roofing plywood to get into your attic. With a metal roof, it isn't happening. That mode of access is eliminated. Now, with our previous asphalt shingles we had constant problems with raccoons pooping on our roof (sound familiar?) and for some reason, at least for the last 10 years that we have had the metal roof, that has not happened. I don't know why, but I can speculate that the raccoons find the metal roof very slippery and they are not comfortable being up there and doing their business while trying not to slide off the roof. Also, in the past we have had squirrels occasionally make their way through, under, beside our asphalt shingles and get into our attic. That will never happen with a metal roof because the whole roof is sealed and northing is getting that way. If you are concerned about high winds ripping off your shingles you don't have to worry with a metal roof. Each and every metal shingle is fastened to the roof with aluminum screws (note the metal roof shingles are painted and baked to a tough finish) and they are interlocked with each other, so you may lose your entire roof in a hurricane, but the metal shingles will still be attached to it. We moved into our new house in 1984. After about 2 years of sweating through humid summers, we installed an A/C system. Our new A/C system worked ok in that it removed the humidity and cooled the house, but with the high 37 deg C temperatures it was struggling. The A/C would run continuously and never stopped on those hot days, but once the metal roof was installed it cycled on and off as designed. We highly recommend Interlock Metal Roofing.

Review: April 12, 2026

Completion: May 30, 2016

We had our roofed replaced by Interlock Roofing in 2016. One of the best decisions we’ve ever made! Our roof looks like slate shingles but is entirely metal. We e received many compliments on it over the years Recently we had a lot of strong wind and hailstorms and our representative, John Mondeshean, checked in with us to see if we sustained any roof damage. He came out and inspected our roof for us within a day or two. Luckily we didn’t have any damage. I’ve been impressed by this company and their product from day one. John is the consummate professional. Our roof is now 10 years old and I still say it was the best investment! Highly recommend!
