Review: November 26, 2010Completion: November 25, 2010

Usually, I don't have the time to write testimonials or reviews of any sort, but in this particular instance, I felt that I need to do so. We all know how stressful and expensive home renovation projects can be. Roofing replacement is one of the most important and also one of the most expensive. As the owner of quite a large apartment building in the established Glebe neighbourhood in Ottawa, my project posed many challenges - proximity to adjacent buildings, a short timeframe and a very high degree of difficulty. Property management allowed me to surround myself with some exceptional trades, but "Interlock Roofing Systems" were unknown to me, just liked the product. The whole experience ended up being outstanding from the moment I met Dave Brown, the salesperson, Sheldon and Tony in the Service department. Professional, efficient, and responsive, but I must say that the crew that did the installation blew me away. Rick, Sandra, Al, James and Sheldon were among the nicest groups of people I've had the pleasure of dealing with in my property management and ownership experience. With their professional approach and respectful and knowledgeable conduct, Rick and the crew made me feel that I was getting outstanding work done by friends. Clean, fast, and efficient... worked in the pouring rain, wind, and freezing temperatures and finished a massive job in a week. We all know when someone goes that "extra mile," and that's what I end up getting from Rick and the guys. The result - OUTSTANDING. Thank you.

Review: June 15, 2021Completion: September 22, 2020

One of those lucky days that I followed a link from a Facebook post. We had immediate follow up and then an appointment scheduled quickly and conveniently with Derek. We had done our homework and we were impressed with Derek's information and approach. Our installation was scheduled quickly. The installers were excellent, personable, professional and very tidy. No mess left behind. After the first winter we are very happy. I would recommend for other to consider more roof guards. Although we are protected over doorways there were mountains from the slide in our garden and on back patio. Not critical but something to consider. Services: Roof installation

Review: October 8, 2010Completion: June 28, 2010

Following the installation of our new Interlock Roof (Slate Style in Green Colour) in late summer 2010, we are pleased to report that we are completely satisfied with the look and appeal of the new roof in addition and, more notably, with the quality of the product and installation. The Interlock installers were quite competent and meticulous in their work and procedures as well as being quite forthcoming and courteous in providing answers to our questions. There was only one minor issue following the installation, and that was resolved on a very timely basis and explains our complete satisfaction with this new Interlock Roofing System on our summer home, originally built in 1940 on the 1000 Islands Parkway between Gananoque and Lansdowne. We are also grateful to Barry Brinson for arranging to have delivered to us a few more green Interlock tiles so that we can adapt and install them to the tops of the birdhouses found on the property! Based on this very positive experience and outcome, we wholeheartedly recommend the Interlock Roofing system/product and the professional installation crew that worked on our summer home in the 1000 Islands.

Review: August 30, 2016

Dear Interlock, My asphalt shingle roof was starting to curl and disintegrate after just ten years. Although I had considered metal the last time around, the cost seemed too high. This experience suddenly made it seem like the better choice. Barry arrived on June 16 and delivered a wonderful presentation on the merits of Interlock aluminum products, reaffirming much of the information available on the internet. The price quoted was more or less as expected, although he did talk me out of the more expensive shake profile which featured in my plans. The one surprise was that my preferred colour, the aged " data-wpil-keyword-link="linked">copper, came at an added cost. It would have been helpful had the website indicated that it commanded a premium price. The timeline was for installation anywhere from 2 to 7 weeks from signing. Provincial Foreman Tony advised me that the boxes of metal shingles and other materials would be delivered on June 27, but they actually arrived early the following morning. Kelly headed up the crew who did the actual installation. He kept me advised about timing and let me know when illness delayed their arrival by a few days. They showed up as promised on July 7 and had about half the house done before noon, working very smoothly together as a team, with the underlayment completed. Note that the underlayment comes with its own 50-year " data-wpil-keyword-link="linked">warranty and claims that it can cover a roof for up to six months without protection. This may be standard but seems like good quality to me. Cleanup was very good. The roof was completed on their second day of work, July 11, with a weekend of rain intervening. They also managed to do the entire garage roof (a separate building) the same day. The house roof is 17 squares, with the garage being another 7. Both are hip roof style. Cleanup was again quite good – I followed around for the final look and didn’t spot anything. However, the next day a closer look around found several strips of the cut asphalt shingles on top of a hedge and in a flower bed (well hidden, in all fairness), along with a few small pieces of cut aluminum which might pose a hazard for some of the younger children who routinely pass through my yard. Yesterday I found two aluminum nails which came to light only after a decent rainfall. Disappointingly, some cut shingles were also left in the gutters which is a much greater problem for an older person, meaning me, to resolve. Note that the noise of the rain on the aluminum roof is not much different from that of the asphalt shingles. Perhaps a slightly higher pitch, but the insulation in the attic and the fact that the old shingles were left on the roof under the aluminum perhaps helped to make it almost unnoticeable. Two days was quite a bit less than the estimated five for the installation. No complaints on this front. From signing the contract to completion was less than four weeks, which ranks as excellent service. Neighbours have been very complimentary about the appearance, with one opining that it’s the best-looking roof in the area. At the end of the day, my house and garage have great looking roofs which should add value when the house is sold (not anytime soon) and will not require replacement for the remainder of my ownership. Interlock personnel all performed admirably, and I am pleased with the final result.

Review: March 31, 2016Completion: March 30, 2016

Loving the roof. Sorry, it had to take a lot of your emails, but I'm really happy it is done. John (never got his last name) from Cornwall was great and had a great crew with him. They did an amazing job and was a pleasure to see their work on my house. Thank Dave Brown for me too, both his visits were pleasant and fun. I learned a lot from him, and we had great conversations, and without him, I would not have gotten my roof done. And also a thank you to you too. That long first conversation I had with you at the home show went a long way in my decision in going with an aluminum roof and with your company. Thanks, and I hope I never have to think about my roof again.

Review: October 4, 2010Completion: September 16, 2010

I had a new Interlock roof installed a few weeks ago and would like to express my appreciation for work well done. Your salesman, Mr. Barry Brinson, who was my first contact with Interlock, was impressive in his knowledge and experience. He gave me the confidence to deal with your establishment. He explained all roofing options and did not put any pressure on me to make an immediate decision. Your roofing team under Mr. John Caverley were quietly efficient and proceeded to do the job in a professional manner that gave me confidence in the quality of their workmanship. They left my property spotless after their clean-up. Please thank them all for me. My roof looks beautiful. It surpassed my expectations in terms of looks, and I know that its durability will not disappoint. Mr. Brinson did not mention one advantage to your roof, which both my wife and I enjoy: we love to hear the sound of the rain softly tapping on the roof. To summarize, I am glad I chose Interlock to do my roof. I could not have had a better team of roofers or a better product. Please express my appreciation to everyone involved for a job well done! Thank you.

Review: February 27, 2019

My wife and I are very impressed with the looks of the INTERLOCK black slate roofing system that was just installed on our home in the Huntclub Road / Conroy Road area in Ottawa. The crew that installed the roofing material during the 3rd and 4th weeks of January 2019 worked through and around temperatures between +.5°C to -25.°C, two weather events that dropped 46 cm of snow and 6 mm of rain and freezing rain plus the occasional days of lite snow flurries. The lead installer told me that a normal installation for the size of our roof could take 2 to 3 days in the spring, summer and fall but with the unpredictable weather doing winter jobs, it can take longer as some days with the extreme cold and dumps of snow it’s just too dangerous to work outside let alone on a roof. The three-person crew was very courteous and answered any and all questions my wife and I had during the installation process, and they made sure the work site was clean and tidy before leaving for home.

Review: October 21, 2014Completion: September 9, 2014

a better estimate on work completion... I was informed it would take 3-5 days & scheduled to be there but I was pleased the work was completed in a day & a half.... I am not sure what the crew supervisors name was John C something I asked him for a card but I was informed I could find him on the internet & that he had been on the Mike Holmes show...I think introducing himself would be more professional..otherwise I am quite satisfied with the work & cleanliness of the job site & the finished project

Metal Roofing FAQs for Homeowners in Ottawa

The following metal roofing FAQs are designed specifically for homeowners in Ottawa, Ontario. 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 Ottawa.

Does metal roofing handle Ottawa's heavy snow and ice buildup?

Yes. Interlock's four-way interlocking panels shed snow and ice efficiently because aluminum conducts heat, and the smooth, hard surface prevents ice dams that trap meltwater on asphalt. Ottawa receives about 144 cm of snow annually, and freeze-thaw cycling occurs roughly 89 days per year—conditions that crack and curl traditional shingles. The panels' light weight (Shingle profile at 0.41 lb/sq ft) means no structural reinforcement, and optional snow guards keep slides from damaging gutters or landscaping below.

How does aluminum roofing survive Ottawa's freeze-thaw cycles?

Aluminum has no iron, so it cannot rust even after repeated expansion and contraction from about 89 freeze-thaw days per year. Its oxide layer self-heals when scratched, and the roofing-grade 3105-H24 / 3003-H24 alloy is engineered to withstand thermal stress without cracking, splitting, or losing structural integrity. Ottawa's average 7.5°C annual temperature, combined with winter lows and spring thaws, challenges materials that absorb water—wood rots, asphalt becomes brittle—but aluminum's inertness means it performs identically in year 10 as year one.

Why can't aluminum roofing rust like steel?

Aluminum contains no iron; rust requires iron. Instead, it develops a microscopic oxide layer that protects the metal beneath and automatically repairs itself when scratched or nicked. The Alunar 70% PVDF fluorocarbon coating—applied to both sides and warranted 30 years against chalking and fading—provides a second, durable barrier. Combined with Ottawa's 883 mm annual rainfall, this dual protection means zero rust risk; steel roofs degrade within years where water pools or runs.

Will my home need structural reinforcement for a metal tile roof?

No. Interlock's Mediterranean Tile profile installs at 0.59 lb/sq ft—about 96% lighter than concrete or clay tile—so no structural upgrades are required. The panels integrate four-way, and most homes can support them over existing asphalt without any framing changes. This light weight also simplifies installation: crews move faster, and the roof can be installed directly over your current shingles, avoiding the cost and landfill impact of a tear-off during Ottawa's brief construction season.

Can a metal roof withstand Ottawa's winter wind gusts?

Yes. The panels are warranted to resist wind speeds up to 120 mph (193 km/h) when installed to specification. Ottawa's typical wind gusts reach 92 km/h, well below this threshold. The four-way interlocking design locks panels edge-to-edge and end-to-end, distributing wind load across the entire roof rather than relying on fasteners alone. This redundancy means gusts that would lift or crack asphalt shingles simply flow over the metal surface without lifting a single panel.

Will a metal roof reduce my insurance premiums after Ottawa hail damage?

Interlock Metal Roofing holds a UL 2218 Class 4 impact rating—the highest available—and the Guardian Warranty covers perforation from hailstones up to 1.5 inches. Because hail is common in Ontario spring and summer, and impact resistance directly affects insurance premiums, many insurers offer discounts for Class 4 metal roofs. Documentation of the rating and warranty can lower your annual homeowner's insurance cost, sometimes recovering a meaningful portion of the roof investment within five to seven years.

What's the lifespan and warranty on an Interlock metal roof?

The Guardian Warranty provides a lifetime limited, non-prorated material warranty for the original owner—covering rusting, rotting, splitting, cracking, curling, and loss of impact resistance. When you sell, the warranty transfers once, granting the next owner 50 years from completion. This is the last roof you buy. Given Ottawa's 89 freeze-thaw days and 144 cm annual snowfall, materials must last decades; aluminum's inertness means it outlasts asphalt (15–20 years) by a factor of three or more, making the lifetime coverage both meaningful and achievable.

How much maintenance does a metal roof need compared to asphalt or wood?

Metal roofs require virtually no maintenance. Asphalt shingles need granule-loss inspections and moss removal in Ottawa's 2903 sunshine hours and 883 mm rain annually; wood shakes demand yearly debris clearing and are vulnerable to rot in freeze-thaw conditions. Interlock's aluminum surface sheds debris naturally, resists mold and rot, and cannot split or curl. Annual gutter cleaning is standard for any roof, but the metal panel itself needs no repairs, sealant reapplication, or seasonal treatment—just periodic visual inspection.

Is a metal roof worth the upfront cost over the long run?

Yes. Asphalt shingles cost less initially but require replacement every 15–20 years; over 50 years, you'll buy and install three roofs plus accumulating repairs. Interlock's lifetime warranty and durability mean one installation lasts the life of your home. Factor in Ottawa's current regional promotion—interest-free payments for 3 months and savings of at least $2499—plus potential insurance discounts from the Class 4 impact rating, and the real cost per year drops sharply. The roof also increases resale value and eliminates future roof emergencies.

Who installs metal roofing in Ottawa and how long have they served the area?

Interlock Metal Roofing (Ontario) Ltd. has served the Ottawa region since 1998, the same year the company began manufacturing panels in Delta, BC. The local team understands Ottawa's 144 cm annual snowfall, 89 freeze-thaw days, and 92 km/h wind gusts—conditions that demand precision installation to warranty standards. With over 25 years of regional experience and ICC-ES ESR-1790 compliance (reissued 2025), they ensure your roof meets code, performs as warranted, and integrates seamlessly with your home's structure and site.

Is a metal roof a good choice for Ottawa’s climate?

Yes. Ottawa averages about 144 cm of snow, 883 mm of rain, roughly 89 freeze–thaw days a year, with peak wind gusts near 92 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.
