Interlock® Aluminum Roofing — all-climates performance specs for Mill Bay, 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. |

Fantastic service from the install team! Perfect precision in every shingle - We have done two houses with Interlock - we would strongly recommend them anytime!
Your prospect or was professionall and persistent.. Your consultant was knowledgeable and professional. We see the value. If your product fits our objectives we will choose it
Final cleanup needs to be double checked, Before the customer finds gutters full of old roofing and metal! Also communication should be made by head office to ensure a project starts on time and Always if there is any change in scheduling..
We would have appreciated it if Interlock Roofing could have gotten to our roof faster. When they did make it out, it ended up there was only one installer that did 99% of the work, and it could have been done much quicker had they had a full installation crew. The installer was excellent.
Believe the aluminum roofing system is very high quality
Interlock Metal Roofing (BC) Ltd. was challenged by the roof on our home but managed to replace the whole roof system and repair some rot that was discovered under the roof they removed because of a faulty installation from another roofing contractor 15 years ago. The team working on the job worked very hard and efficiently and had the job done in just over two weeks.
Speck house. Went with asphalt shingles.
The initial pricing was quite high. I found the product quite pricey.
We just can't afford to do it right now.
Until corrective action was taken by management, some employees did construction work they were not qualified to do.
