Interlock® Aluminum Roofing — all-climates performance specs for Wellesley, 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:
I would highly recommend your company to anyone looking to have a metal roof installed.
from our initial inquiry to peoject completion our experience was great
I got the estimate and they told me they would come back if the manager approves the price, and two weeks later they said the manger approved the price. Two months later they called and said the estimate was not right, so I agreed to pay that and said to go ahead and do it, but they never called me. There should be more communication between them and their client. Also, they gave me a letter and an 800 number to call seven days a week, and every time I'd call I had to wait a couple of days for a response, and that's a problem.
No need for improvement
There could have been better communication between me and my salesman.
Nothing.
I would but I think interlock roofing should fix some problems. The quality of the roof is okay but some things need more improvement in and doing the job professionally.
The timeline was a little bit longer than what we expected. The cleanup wasn't perfect and part of that might have been due to the fact that I have a number of gardens around the house and maybe you can't see the debris in them.
