Interlock® Aluminum Roofing — all-climates performance specs for Dorchester, New Brunswick
| 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:
no areas of concern for me - wonderful crew, business, thankyou never saw a crew so dedicated, respectful - where did they come from??
Paul Paquet is a five-star guy! We have a 1925 house with a 1999 addition, and the attic has winter humidity ventilation challenges. Paul walked me through his diagnosis, and his resolution gives me confidence that winter woes are behind us. I'm very pleased.
They could improve with the advertising signage on my lawn. It is only in English. They should have a french one since I live in the french company. They should do siding and windows. I am happy about the decision to go with them even though it was more expensive I sit on my deck and admire my roof.
I was surprised to not have a supervisor on-site to inspect the work. I had a hard time getting ahold of Bob to discuss the materials left on site. They could've communicated a little better at the end of the project. The service was good and the install team was open to any feedback I had to give them. They were very professional.
I think they have a really good product, but I am not sure if I can afford it.
Nothing that I can think of
We got our roof done over 13 years ago and the roof is still impeccable. We live in the Moncton area and it was worth the price. We never have to worry about the roof ever again.
Yes. Overall, it was appreciated.
I'd say my house has the nicest-looking roof on my street. The choice of patterns and colors is really a nice feature. It's worth it if you can afford it. The company is much more professional than any local contractor (and I talked to several). It feels strange always calling a toll-free number during Pacific time for any concerns. After we signed the contract, we were expecting to have local contact person. Thank you for the opportunity to give feedback!
Interlock Roofing could have improved on the installation part. I am extremely satisfied with the project. During the installation there were smokers and they left cigarette butts after.
