Interlock® Aluminum Roofing — all-climates performance specs for Penetanguishene, 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:
From start to finish Interlock Roofing exceeded our expectations. We have a steep roof with dormers/intricate angles and many roofers denied the job. We felt completely confident throughout the whole process that we chose the best type of roof for life on Georgian Bay. Bruce was incredible form beginning to end. The installation team, John Sr., John Jr. and CJ, were incredible. They made sure everything was cleaned up and organized daily. They worked from day to evening, no matter the weather to ensure the job was done in a timely matter. Highly recommend Interlock Roofing aluminum roofing!
The gentleman was professional and there were no issues. He was informative and he did do wonderful.
Needs more roofing staff Thank you for all the hard work & care that went into my beautiful home
They could have improved on the price.
Not at this time
The supervising installer was unprofessional and I did not like working with him.
Not much, but a) Did not receive advance call regarding project start; b) Project was completed around 9:00 pm, making it challenging to complete everything, clean up and load up, as it was dark. (Still awaiting the freely transferable warranty in the name of both me and my wife (Vivian Sutherland
