Interlock® Aluminum Roofing — all-climates performance specs for Norwich, 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:
We purchased this product from Interlock after admiring other projects they had completed in our neighborhood. The owners of the other homes highly recommended Interlock Industries, as do we. Our roof has drawn interest from many passerby’s during the installation and since completion. The charcoal slate product we selected is very striking. The Installer who completed the project did an excellent job and was thorough in his cleanup during and at the end of the project. Since the aluminum “shingles” were installed on top of the existing shingles there was no need to dump a whole load of old materials into landfill which was an important consideration in our decision. And since our original roof was in fairly good condition, a layer of strapping was not required before installing the aluminum product. Positive: Professionalism, Value Services: Roof installation
Carter and his crew did an outstanding job from the moment Carter stepped in the house for the quote to the day his crew cleaned up and left. Very professional. I highly recommend Interlock.
Well done work, courteous Very happy, job well done Very pleased with the appearance of the roof.
I had an Interlock Metal roof installed 2 years ago and could not be happier. The initial meeting was very informative and Bruce was extremely knowledgeable. The installation of both roof and skylight went smoothly and I'm still very happy with the product. Services: Roof installation, Skylight installation
And have done so and will continue to. Cannot answer this question at this point as everything was done great. As this is my first Interlock roof and it is now a grand total of 2 weeks old I cannot comment on the quality and durability of the aluminum but I expect it will perform as advertised and I look forward to never having to worry about a roof again. Nothing additional to say but I will reiterate that we are very happy with our new roof and will continue to pass the word that while more expensive than a traditional shingle roof today, it is worth every penny and anyone looking for a new roof should consider Interlock Roofing. It truly is the last roof you will ever need. (sorry had to steal their line).Mike and Cathy
Its new, but seems to be a fairly good product. I'm happy with how it turned out. They went over and above and put on extra ice breakers. Everything was awesome except it was too expensive.
Communication and immediate followup at the end of the job. There was none and still has not been any. Thanks for our beautiful new roof!
I am waiting for confirmation of when interlock is going to replace the roof they did twenty years ago.for me at 23065 Adelaide st n. I showed it to Bruce and he said it will be replaced, and took pictures of the peeling paint. Looking forward to recommending Interlock, once the work mentioned above is redone. Paint peeling excessivly is not what I paid for or expected.
none on this job but should have been informed about snow guards on previous instalation quite happy with both roof instalations
I am very pleased with the customer service!
It was very nice, and I would recommend Interlock Roofing to my friends and whoever else needs them.
I would say they should put on more snow guards. It was a long project. I don't know if they normally take 6-7 days. We were home when it was being done and during covid. We were very understanding of the team's needs to use our facilities. We really sort of became a family. Having a project that takes that long, I personally felt it was slightly intrusive into my space, even though we love them all.
