Interlock® Aluminum Roofing — all-climates performance specs for Lower Mission, British Columbia
| 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:
Interlock is the best roofing available in our opinion and now have had it installed on our second home. Our 1st home had the shingles installed in 2009, and helped sell the home in 2021, as they looked identical to when installed, had no issues and had the transferable 50 year warranty for the second owner. We just got our new house fitted with interlock roofing, as our original (40 year warranty asphalt shingles) were deemed uninsurable (at 23 years old) when trying to get insurance and recently started leaking. Now to the new interlock roof and the customer service. The team is amazing, and professional, they got our roof on, were available to answer any questions, and ensured we were 100%.satisfied before the team left and final payment was made. Decision for the roof was mainly due previous satisfaction, but we also loved knowing we don’t have annual costs/work in the future for things such as moss removal. The roof great for wind, hail and fire rating as well with is a bonus in the Okanagan.
We loved the company, and loved the installers.
the product is just too expensive for my ability to pay those amounts quoted.THANKYOU FOR YOUR TIMEBILL BIDEN
They could have improved with proper training of the installation crew. The big issue was with the installer. With regard to the installation, they need to improve the training of the installation crew and the installation crew needs to be better at communicating. Lots of broken promises.
Arriving and completing the job when they said they would.
John does have a few basic questions that he would like to be answered.
If they could have let me know what space the workers would be using during the project that would have been helpful.
Overall , I am very satisfied with my new roof. It only took a week to complete. Mike the installer did a very nice job , with as little disruption as possible. I am happy to say that I will not have to worry about my roof again. I was very satisfied with the project in it's entirety. Very satisfied
solid work. Quick and clean. No big mess. Engageable workers.
Better planning on the part of the installation crew
