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:

Janer and Luis replaced our ridge venting. They did a super job. They are very professional and knowledgeable. Janer provided important information on venting our attic and was very helpful and accommodating. He answered our questions with thoughtful responses.

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]
