Interlock® Aluminum Roofing — all-climates performance specs for Forest, 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:
They need to know how important communication is. They need to stay in touch with the customer more often. I am very happy, so far, with the job they did.
I am on my way out, but I will give them excellent on everything.
I think they could improve on the scheduling and making sure they do what the contract stated.
I had to get an old pipe removed from the roof and required new shingles to be installed where the pipe was. The roofer showed up on time and went above and beyond to get the roof looking like nothing had ever been there.
I think Interlock Roofing could have improved on their timing.Interlock Roofing was a couple weeks off but I think that was because of another project that they did not get finished. It was not a big deal to me that they were a little late.
This was a steep roof and with only one employee on the job it took much longer than necessary.
This was a steep roof and with only one employee on the job it took much longer than necessary. He took all appropriate safety precautions and wore safety gear but an extra person would have been safer and three times faster. Although not part of the original agreement, I requested some eave troughs to be replaced and gutter guards installed. I am still waiting for this work.
The project stalled because of the interface between the solar company and the interlock installers.It took the installers almost a whole month to come back and finish the job.The communication between interlock, installers and us was very poor.Recommend that you encourage people with solar panels to use your preferred solar contractor to avoid these type of issues.
