Interlock® Aluminum Roofing — all-climates performance specs for Cokotoks, Alberta
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
I am pleased to say that the installation went very smoothly and that it was a pleasant experience. The installers were always in time, courteous, fast and professional. The thorough cleaning of the garden and around the house was particularly appreciated. The changes on the house are beyond expectations and the general curb appeal, with the stone tiles, making it the best of the neighbourhood. The added value to the house is obvious and I will certainly recommend Interlock to anybody. It was overall a very positive experience.
As I promised, here is our very belated letter following the installation of our new Interlock Roof in mid April of this year. Mark and Martin, our installers, were terrific. They were courteous and friendly and Mark took the time to answer all my questions. They cleaned up those huge mounds of old shakes completely and they left the worksite neat and tidy at the end of each day. They did a great job! We are very happy with the appearance of the roof and knowing that we are worry free for the rest of our lives is a good feeling.
Mary & I are pleased to let you know that we are delighted with our new Interlock roof and we would recommend you and the product to anyone who inquires. We have had many compliments from neighbours and strangers. The 'weathered gray' colour was the perfect choice for our home and the roof looks great. It fits in well with the existing pine shake roofs in Valley Ridge.
Our experience with Interlock Metal Roofing Systems can only be described as highly recommended. From the start, Matthew was very knowledgeable on the roofing product and was able to fully describe what was needed for our house. He was able to give us multiple examples of homes that had this system installed on it which allowed us to visualize and decide on the style that we wanted. Once this was completed, he went out of his way to ensure that all of our questions were answered and that we were educated on this product. After the roof was ordered, Shauna did an exceptional job communicating the status of our roof and when it was expected to be delivered as well as when the installation would begin. She was extremely thorough in what we were to expect and the timing of everything that would occur. Due to it being a custom roof, the materials had to be manufactured prior to the installation being done. Our installer, Oswaldo, and his crew can only be described as extraordinary! They are truly Master Craftsmen and are some of the best we have ever worked with on ANY project. Their thoroughness, attention to detail, communication and general demeanor were beyond anything that could have been expected. We could not be prouder of the way the job was completed and we are very happy with the Interlock Metal Roofing System that was installed. The finished product truly is a work of art that will enhance our home for years to come!
I did a lot of research prior to selecting Interlock roofing. There are an abundance of good roofing material on the market but I was looking for a very long term and maintenance free product. Interlock offered an excellent product and a great warranty. Their installers showed up on time, were very professional and courteous, and did the job within the estimated time schedule and price. Before the job was even started a few things were pointed out which required some slight roof modifications and venting changes. This was explained to me in a very professional and understanding way. Any sections of underlying plywood which were not up to standard were also replaced at the agreed upon price. Before any changes were made I was shown the reason why and I gave approval prior to proceeding. I am very happy with the installation and product and would definitely endorse an installation through Interlock. I waited 3 years before writing this review because I wanted to make sure everything worked properly without any call backs.
I've had a few days to get used to the look of the new roof, and I can't believe how good it looks, nothing like the metal roofs of old. It looks like slate, exactly as you said it would. Arthur (the roofer) was a real pleasure, polite, friendly and very hard working. He took great efforts to clean up any debris at the end of each day.
All Interlock personnel we dealt with were personable, courteous and professional. The installer (whose name I don't recall) was a very able, diligent and hard worker. When he had helpers onsite - primarily for stripping the old shake and asphalt roof materials - they also worked well and without loud music or coarse language. Also, our contact at Interlock's office (Shawna) was courteous and helpful - even to lending us the heavy material display panel from the showroom to take home for a weekend AND helping me load it in my car! We've had positive comments from neighbors and from passers-by when we're outside. One of the more interesting was, "We loved the look of your old cedar shake roof and were afraid what you might be replacing it with, but it looks great - good choice!
We first saw an interlock roof further down the road and decided to call for a quote. We were aware it was more expensive but I was pleased when Neil let us know how much more at the beginning of his initial assessment with us. I found all Interlock staff to be professional and courteous. However, the best thing now is I have a roof that look fantastic and will last me a lifetime. Thank you Interlock none
Overall, we are satisfied with the speed in which it was completed, and the quality of work. We are happy with the end results. They need to do better with the cleanup and to do a thorough check to make sure all things are cleaned up. We are satisfied with the quality and the speed in which it was done.
After 25 years in our home we realized it was time to replace our roof. Asphalt shingles were always the way to go ..however, we decided to investigate other products. We have always been very interested in a tin roof but were worried it may be too shiny for our home. After thorough research we saw the Interlock product at a home show & became immediately interested in the different styles & colour choices. We set up an appointment in our home with Tyler to have Interlock view our roof line to make sure the slate style look would work. The product is strong, lightweight, tough durable & comes with a 50 year transferable warranty. We were impressed to say the least. Now that our roof is complete (Wow) thanks to the professional installation by Alexis the neighbourhood is abuzz with questions & compliments. It’s beautiful!!! & the Interlock slate style compliments our home. Thank you Tyler for all the information & support in helping us make a rewarding decision. We couldn’t be happier!
They're wonderful. They have been very safety conscious, they have provided excellent work, they displayed excellent work ethics, and they were extremely careful about how to work within the property. Very prompt and very professional.
After a relentless 12+ hour windstorm, our 18-year-old roof needed a repair. When I called to book it, that's when I learned the previous owner and my senior parents hadn't transferred the warranty when the house was bought 13 years ago. Despite that, the owners came out the very same day and honored it! The repair itself was simple — just two screws — but high up on the roof with a sloped ground below, making it tricky and time-consuming. First time in 18 years our roof has needed work, and their honesty, professionalism, and prompt service were incredible. Highly recommend this company!

Metal Roofing FAQs for Homeowners in Cokotoks
The following metal roofing FAQs are designed specifically for homeowners in Cokotoks, Alberta. Whether you are building a new home or replacing an existing roof, understanding how roofing materials perform in local weather conditions is essential. From wind and storm protection to fire resistance, hail impact, snow loads, and coastal moisture exposure, Interlock’s Lifetime Aluminum Roofing System is engineered to provide long-term durability, energy efficiency, and peace of mind in Cokotoks.
How does a metal roof handle Cokotoks' heavy snow and ice buildup?
Metal roofs shed snow and ice far more effectively than asphalt because the smooth, hard surface prevents water from refreezing at the eaves. With about 117 cm of snow annually and roughly 130 freeze-thaw days per year, Cokotoks homes face real ice-dam risk; Interlock's four-way interlocking panels lock together so tightly that snow load distributes evenly without gaps where melt can refreeze. The panels are also extraordinarily light—the Shingle weighs just 0.41 lb/sq ft—so your structure handles the snow weight with ease. We recommend snow guards for aesthetic or safety reasons, but the roof itself won't trap ice the way asphalt does.
Will freeze-thaw cycles in Alberta damage a metal roof?
No—aluminum actually thrives in freeze-thaw climates because it has no iron content and cannot rust, even when exposed to 130 annual freeze-thaw cycles like Cokotoks experiences. The metal's oxide layer is self-healing; if a branch or hail scratches it, the layer reforms naturally without rusting or degrading. Steel roofs, by contrast, will eventually rust from repeated moisture exposure during those 130 cycles. Interlock panels are finished with Alunar 70% PVDF fluorocarbon coating on both sides—warranted 30 years against fading—so the protective barrier itself withstands Alberta's temperature swings without fail.
What's the hail rating on Interlock metal roofing, and can it lower my insurance?
Interlock panels carry a UL 2218 Class 4 impact rating—the highest available—and the warranty even covers hailstone perforation up to 1.5 inches. Many Alberta insurers offer discounts for Class 4 roofing because hail claims are so rare; contact your provider with the UL 2218 rating to explore savings. Cokotoks receives about 342 mm of rain annually, and while severe hail is not guaranteed every year, the durability rating gives you complete peace of mind. A Class 4 metal roof is one of the few products that can actually improve your insurance position rather than just meet it.
Can a metal roof withstand the gusts we get in Cokotoks?
Yes. Interlock panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification, and Cokotoks' typical wind gusts reach about 124 km/h—well within that margin. The secret is the four-way interlocking design: each panel locks to its neighbors on all sides, creating a unified system that distributes wind load across the entire roof rather than allowing individual panels to lift or separate. This engineering is proven in coastal salt-air homes and Antarctic research stations. Your local Interlock installer, serving the region since 1999, knows exactly how to secure panels for Alberta wind conditions.
Why doesn't aluminum rust like steel metal roofing?
Aluminum contains no iron—the element that oxidizes and rusts—so rust is physically impossible. Interlock uses roofing-grade 3105-H24 and 3003-H24 aluminum alloy (ASTM B209), which forms a thin, transparent oxide layer when exposed to air; if scratched, that layer reforms automatically without iron oxide (rust) ever forming. Steel roofing, by contrast, relies on paint or coating to prevent rust, and those coatings fail over time, especially in freeze-thaw climates like Cokotoks with 130 annual cycles. Aluminum's protection is permanent and self-healing, not dependent on a failing coating. It's why Interlock panels have been installed since 1998 in everything from salt-air coastal homes to Antarctica.
What warranty comes with an Interlock metal roof, and how long will it actually last?
The Guardian Warranty is a lifetime limited, non-prorated material warranty for you as the original owner—it covers rusting, rotting, splitting, cracking, curling, and loss of impact resistance with no depreciation over time. That means a claim in year 25 is treated the same as a claim in year 5. The warranty is also transferable once to the next owner, who receives 50 years of coverage from completion. This structure reflects the product's real durability: aluminum doesn't rot, won't split or curl like asphalt or wood, and the Alunar coating is warranted 30 years against chalking and fading. Many homeowners find it's genuinely the last roof they'll install.
Is a metal roof worth the cost compared to asphalt shingles?
Metal roofing costs more upfront than asphalt—typically $2,500–$5,000 more for a Cokotoks home—but the total cost of ownership over 40–50 years strongly favors metal. Asphalt roofs need replacement every 15–20 years; you'll buy 2–3 of them while your Interlock roof lives 40+ years with no replacement. Add in zero maintenance (no cleaning, no repairs), no ice dams costing $500–$1,500 to fix, and potential insurance discounts on Class 4 hail roofing, and the math becomes clear. Right now, Interlock is offering interest-free payments for 3 months and savings of at least $2,499 on installation, which significantly narrows that upfront gap. It's the 'last roof you buy' in financial terms, not just durability.
Do metal roofs really save energy, or is that marketing?
Metal roofs save energy by reflecting heat rather than absorbing it like asphalt. Interlock's energy-efficient colors achieve thermal emissivity of 0.84 and initial solar reflectance up to 0.55 (Aged Copper Penny), meaning they bounce back the sun's heat instead of turning it into attic warmth. In Cokotoks, with about 3,392 sunshine hours per year, that reflection adds up—especially on hot days when cooling load matters. The Cool Roof Rating Council rates these colors, so the performance is independently verified, not estimated. You won't see savings in deep winter, but from April through September, lighter-colored metal roofing measurably reduces air-conditioning run time. Combined with the metal's durability, energy efficiency makes it a genuine long-term investment.
How much upkeep does a metal roof need compared to shingles or tile?
Almost none. Metal roofs require no annual cleaning, no moss treatment, no re-sealing, and no repair of curled or split shingles—tasks that consume hundreds of dollars on asphalt roofs over time. Interlock's aluminum panels don't rot, crack, or curl in Cokotoks' 130 annual freeze-thaw cycles the way asphalt or wood does. You may occasionally clear leaves from gutters or trim overhanging branches (standard for any roof), but that's the extent of it. The roof is ICC-ES ESR-1790 compliant and CALGreen-verified for reduced maintenance. Compare this to tile roofs, which need regular inspection for cracked tiles, or asphalt, which demands constant attention as it ages. Over 40 years, that low-maintenance advantage translates to real savings in time and money.
Can my house structure handle a metal roof, or do I need reinforcement?
You almost certainly don't need reinforcement. Interlock's metal panels are extraordinarily light—the Mediterranean Tile profile, which mimics heavy clay or concrete tile, weighs just 0.59 lb/sq ft and is roughly 96% lighter than the real thing. Even the heaviest Shake profile weighs only 0.58 lb/sq ft. Most Cokotoks homes can handle metal roofing directly over existing asphalt shingles without any structural upgrade because the weight is so minimal. This also means installation is faster and less disruptive than removing and replacing heavier materials. If your home has any structural concerns, your local Interlock installer—serving Alberta since 1999—will assess during the free inspection, but the lightweight design solves the problem for the vast majority of homeowners.
Is a metal roof a good choice for Cokotoks’s climate?
Yes. Cokotoks averages about 117 cm of snow, 342 mm of rain, roughly 130 freeze–thaw days a year, with peak wind gusts near 124 km/h. Interlock® aluminum roofing is wind-rated to 193+ km/h (120 mph), UL 2218 Class 4 impact-rated and Class A fire-rated, and its four-way interlocking panels shed snow and resist ice dams and freeze–thaw cracking — all backed by a lifetime limited, transferable warranty.
