Interlock® Aluminum Roofing — all-climates performance specs for Madoc, 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:
John and his crew did an amazing job on our roof. It looks absolutely outstanding. There was no cleanup after they cleaned everything up. They are very professional. They have an amazing warranty that is transferable. I highly recommend them.
My current project is a rental that I expect to sell within 2-5 years. I will reconsider if and when I build my next home. Chris was excellent. Thank you for your time. Jeff Sharpe
You could probably improve on being more in touch with the customer. There were weeks and months between when we signed the agreement until the job was done. We just had the roof a few weeks ago. If everything holds up we will be very happy.
Taking on a new roof as a first time home owner was a challenge, and in the heights of COVID, it felt even scarier. Derek and his team worked with us online, and took images from google (without having to come and measure) and we had our new roof within 1.5 months. We loved the product, that the company doesn’t subcontract, and of course, the warranty!
Maybe a bit more attention to the need for snow/ice cleats other than at entrance points (ie neighbors driveway etc) Love the new roof, get quite a few compliments. My apologies for the late reply to this survey!
None that we can think of
A call back after install was completed.
Maybe allow for more snow guards. Hopefully I can give as good a report after a number of years.
Communication between project management and crew
They could improve on showing different patterns of how they can put a roof together.
My husband is the one who wanted it and my husband likes the look of it.
Communication. Haven’t heard from anyone except the installer, and you, since the roof went on.
