Interlock® Aluminum Roofing — all-climates performance specs for Clarington, Ontario
| 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:
From the time that we first called with questions about a metal roof until the time our roof was installed and we received our warranty, Interlock Metal Roofing treated us like a valued customer and appreciated our business. The sales and installation teams are awesome and we are very happy with our purchase. Thank you! Jeff and Paula- Oshawa. Positive: Responsiveness, Quality, Professionalism, Value Services: Roof installation
Outstanding metal roofing installation in Oshawa, ON by Interlock Metal Roofing (Ontario) Ltd.—the crew removed our old roof and installed a beautiful new metal roof that looks great and adds lasting curb appeal.
Interlock Roofing could have improved a little bit on cleanliness. Small metal pieces were hidden in the bushes of my garden. Interlock Roofing was outstanding and went beyond my expectations.
There is on a corner that has a very sharp edge that I'm worried about. They were fast and thorough. They fixed an issue seamlessly.
On July 23 2014 when roof installation was competed we were highly satisfied with both product and service, but had issues with the installation of snow guards (Some were missed in installation and had to be retrofitted. Others were misplaced) . THEN, it all went south. 1 1/2 boxes of left over shingles were removed following completion of the roofing without our permission. These have not been returned nor credited. A serious leak (1 1/2 inches per half hour) occurred twice due to a faulty designed roof vent has left the roof less than pristine following correction (traffic and retrofitted shingles). In the second case, we had to install a tarp at 2:00 in the morning during a thunder storm to prevent further damage, water running across the floor, down registers, and into the basement.THEN, we had to deal with Tony Lupton and his supervisor Martin Piatoca regarding compensation. The leak has been fixed but the interior damage remains unresolved two months later with no resolution in sight.When the leak was reported, Tony allowed us to retain $5000 from our payment to deal with the repairs. Excellent. When we began negotiations surrounding the $5000 for "our dissatisfaction, our past efforts, and inconvenience related to the leaks, the expected efforts and inconvenience to perform ceiling repairs and the cost of the repairs and various aspects of the install." we were presented with invoice ONMS 14 096 that included a typed message - " Warranty will be voided if 3 quotes for damages are not received within 14 days". We did not agree to get 3 quotes without an understanding of the value of our efforts, and we could not meet the timeline. Consequently, we paid the $5000 on Sept 03, 2014 to retain the warranty, and are awaiting its delivery. We do not agree that surplus materials, paid for by us, are the property of Interlock.We do not not agree that we should be expected to provide services on Interlock's behalf for free. We do not agree that improper installation has the same value as proper installation (snow guards and vent).We do not agree with Tony and Martin's approach to compensation negotiations, but the Patty Means' post in Homestars.com combined with our experience, suggests threats to revoke the warranty is a company approved tactic. If so, our paying $5000 to retain the warranty was a bad investment. But hopefully sober minds will see our experience, and the warranty tactic has a much more far reaching and consequently more serious business impact.If you are sincere in your "ongoing efforts to deliver a consistently exceptional customer experience", please review our case and resume negotiations to restore our experience to exceptional - where we once were..
I think Interlock Roofing could have improved if they would have had two guys instead of one. So that it wouldn't have take four days. They said it would take 2-3 days tops.
I think the roof had more technology in it then I knew. I think they could've explained that type of explanation better.
Customer service and trying to get a repair scheduled and the company back out to the job site. They delayed the installation after setting the schedule on the initial meeting.
I feel I have made a great decision in choosing an Interlock roof. It looks beautiful and most of all I have peace of mind. I have a roof that should out last me and I'm okay with that! Thank you and I will tell everyone what a positive experience I have had with your company.
