Interlock® Aluminum Roofing — all-climates performance specs for Dwight, 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:
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!!
The entire process was smooth and easy I would highly recommend anyone looking for a new roof to use this company my house is over 110 years old and they made the end result absolutely spectacular all of the people that I dealt with were professional and they delivered exactly what they promised and on time Thank you
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.
Salesman and installers were excellent to deal with
Evwryrhing was great and i can see no need for improvement
I was extremely satisfied and Yves installation seems good.
None
I was very satisfied.
communication
I am still waiting for the work to be completed, I am still unable to open my gable windows, because the new roofing is restricting them from opening.
The clean up. Our property was left with debris all over the yard and at our main entrance.. A change in weather didn't help, as snow covered the debris part way through the project; however, the crew could've cleaned up when they knew the snow was coming. We are very disappointed in how our property was left and that clean up did not appear to be a priority.
