Interlock® Aluminum Roofing — all-climates performance specs for McKellar, 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:
We are very happy with the roofing. Afterwards, there were so many metal pieces left over from the roofing metal. We still had old shingles on the roof, and there were some pieces of that as well left behind. We are very happy with the roof, and it looks great. They got it started fast. I was told it would be 6 weeks, but it was only 4 weeks. We love the roof. Even though they didn't clean up afterwards, it was great. I would still ask them to come install a roof for us and request the same installation crew. Bruce was great from beginning to end, and I love the roofing system.
Our new metal roof was completed on time with very little disruption. As retired home-owners we are pleased we will never have to re-roof in our lifetime. Our new roof attracts positive comments from our neighbors and makes our old, stone house look fantastic. A great investment!!
Great product. Bruce was great in explaining the product at the outset. Professional installation. Installers were on time every day and very neat. Highly recommended. Positive: Professionalism Services:Roof installation
I don't know, it is hard to say because I was not here. I was happy overall and I did not have any problems. I am very happy with the workmanship, the follow up, and the final product.
I would only suggest that a small garbage bin would have made the work faster, not having to do trips to the dump with the roofing material they removed as well as the scraps from the new roof. I love the my new roof and have already had many positive comments on it. :) Thank you.
I don't think there is anything Interlock Metal Roofing could have improved on during the project. They did a great job.
I was extremely satisfied and Yves installation seems good.
I wish it was a little cheaper. It was done really well. I am done for the rest of my life.
None
I do have one concern: The top floor of our house has a roof that is more pitched, where snow slides off easily. Then the attached garage is underneath that. When the snow slides off the top part, it builds up on top of the garage.
I was very satisfied.
See above notes: it is/was the finer things like shingle pieces in the gutters, sheathing still needing trimming, one piece of side fascia looks like it may need more fasteners, and not hearing back about an inspection which would give us a chance to ask questions.
