Interlock® Aluminum Roofing — all-climates performance specs for Cornwall, Prince Edward Island
| 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 are very professional, and it was extremely well done. It certainly looks like quality work to me. We've had lots of comments on it. There are no areas in which Interlock Metal Roofing could have improved.
Interlock Metal Roofing- Halifax was great, so I have no areas of improvement. I am completely satisfied.
They could have finished sooner had they not ran out of roofing materials. I'm very happy with the project.
They could have done a better job explaining the material that was being used and where it was being used. We are very pleased and we are getting nice comments from the general public.
Lower the cost Roof looks great had a lot of great coments. A little concerned about the snow sliding off it. I wouldn’t want to be standing under it.
Everything was good.
E mail receipts after payments
I can't get up on the roof to really test it out, but time will tell. Thank you. There could be a problem in that your company is too successful to meet all the starting dates, but it isn't anything I would complain about in the end.
Interlock Roofing could have started the job a little latter in the morning. We had a pretty good experience.The only negative thing was Bob told us he would bring a sign to put out on our lawn, but we have yet to receive the sign.
Communication is a key area for improvement. I would like to have someone come out in the spring to look over the job. The wood trim has some exposed ends.

They could have improved on letting us know exactly what day they were coming.
