The Interlock Roofing System was delivered and installed on time in spite of a delay in startup due to rain and another day delay due to rain after half the roof was done.
The crew was courteous and friendly and cleaned up at the end of every day. I was very satisfied that the place was left tidy and clean after final cleanup.
I recommend Interlock Roofing to anyone wanting an impressive nice looking roof.

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

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.

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.

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]

Kamloops, British Columbia, is shaped by its river valleys, rugged hills, and an impressive 2,000 hours of sunshine yearly. Just above the winding Nechako Drive, not far from the banks of the South Thompson River, Rob’s home now carries something as enduring as the land it stands on: a Deep Charcoal Interlock Shake Metal Roofing System.
This neighbourhood is more than a quiet hillside—it’s part of a city known for its spirit. Kamloops is proudly called the Tournament Capital of Canada, and whether it’s athletics, arts, or architecture, this community shows up with intention. A home here deserves the same care and attention to performance. That’s exactly what Rob found in his experience with Interlock.
Rob’s 5-Star Review:
This isn’t just about metal roofing. It’s about trusting a system that won’t crack, curl, or quit. The Interlock Metal Roofing System delivers what most products promise but can’t: a lifetime of durability, energy efficiency, and peace of mind. In a city where winter winds roll off the mountains and the summer sun hits hard, having a roof that’s wind-resistant, solar-compatible, and built to last isn’t a luxury—it’s thoughtful planning that makes you feel smart and resourceful.
And the best part? Rob will never re-roof again. That’s not just a marketing claim. It’s a testament to the reliability of the Interlock Metal Roofing System—a 4-way interlocking system backed by a lifetime warranty, installed by a team that, as Rob puts it, ‘takes pride in their workmanship.
Your roof is more than just a lid on your house. It’s your first line of defence, a bold statement of style, and—if you choose wisely—the last one you’ll ever need, just like Rob did in Kamloops with the Interlock Metal Roofing System.
Kamloops experiences a semi-arid climate with hot, dry summers, cold winters, and high UV exposure year-round. This combination takes a toll on most roofing materials.
Interlock® Metal Roofing is engineered to thrive in Kamloops’ climate. It reflects UV rays to reduce heat buildup, withstands freeze-thaw cycles, sheds snow easily, and resists wind up to 193 km/h (120 mph)—a smart choice in a city known for dramatic seasonal shifts.
Most asphalt roofs in Kamloops last 10–15 years due to UV degradation and thermal cracking. Even synthetic and rubber options top out around 30–50 years with maintenance.
Interlock Metal Roofing comes with a lifetime, non-prorated warranty—so you’ll never re-roof again. The aluminum alloy resists corrosion, cracking, and fading far beyond the lifespan of most traditional materials.
The Final Takeaway for Kamloops Homeowners
In a city with long, dry summers, cold winters, and high UV exposure, roofing materials are tested year-round. Asphalt, rubber, synthetic, and even steel will eventually wear down, crack, or corrode.
Interlock Metal Roofing offers a smarter alternative:
It’s not just a roof. It’s a long-term solution built for the unique climate and character of Kamloops, BC.
To whom it may concern, Interlock Industries:
I am writing to boast of my new roof, that I am l 00% satisfied with both the roof itself and the service of installation.
The installers arrived promptly, as they had planned ahead of time. Also, the materials were at the site exactly, so there were no delays; work progressed on schedule. The laborers were courteous, informative and very professional. They were on time in the morning, everyday, and they did not work late, as to be a bother in the evenings.
The roof itself looks fantastic, and I have a very secure peace of mind. With a solid and transferable 50 year guarantee, I have no doubts or worries.
Interlock is a leader in the field of roofing companies, and I am sure this company will be around for a very long time.
Thanks again, Todd.
