Interlock® Aluminum Roofing — all-climates performance specs for North Grafton, Massachusetts
| 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:
I recently had Interlock Roofing System installed on my house; I was greatly pleased and surprised by the prompt and professional manner in which it was installed. My house, being older, required much work (new plywood panelling, and I requested additional work (new chimney, venting, window, solar tunnel, removal of an old venting window, and removal of a light panel). The roofing system looks great. As my neighbor said. "I never thought I would say this about a roof, but your roof looks gorgeous." I would recommend the Interlock Roofing System to anyone.
No more problems with moss and lichens, like I had with the asphalt shingles. I am extremely happy with my new Interlock Roofing System and to think it has a lifetime warranty. There have been several rainstorms that last couple of weeks and to me the metal roof had added no additional noise at all. The flat roof is also a welcomed addition. The material quality is tip-notch throughout.
The job was done efficiently and in a timely manner. Everything promised was delivered in terms of quality and performance. The roof is beautiful, and we will never have to put another one on our house. None. We've had a lot of projects done in the 48 years we've owned this house. Nobody paid as much attention to the details as the Interlock management and crew. Top marks for all involved. Thank you.
There is nothing they could have improved, I thought they were great! I hope to get the advertisement sign back up.
I am very happy with the new roof. I wish they had something to carry the cut material. When they cut in the middle, the material fell down off the roof.
No
Have not met Mr Koch Larry Ebbs was my representative
I had my roof installed in May 2003. I noticed the coating had some peeling in 2021. I contacted them in the beginning 0f June 2021 and by the end of June they had approved my claim. It took 8 months but they replaced my entire roof with no charge at all to me.
Will sign be picked up or should I dispose of?
