Interlock® Aluminum Roofing — all-climates performance specs for Cohasset, 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:
Interlock Metal Roofing exceeded our expectations. It is so beautiful that it takes my breath away. In the winter, the house is warmer, and the snow slides right off. I can't think of a thing they could improve on. They were faster than I thought possible. They were pushing hard because of the cold weather that was coming. Everything was fantastic. They set up where I said they could. They cleaned up and looked for nails with a machine. I couldn't believe how wonderful they were.
I am writing this letter to you and the installation crew that installed my Interlock Roof I have on my home. I would like to let you know how delighted and happy I am with my Interlock Roof. Thanks again for the superb service that was given to me. I would highly recommend the Interlock Roofing System to anyone interested in a new roof and never having to roof again.
They were so professional ! We are so pleased with the quality of work and materials. We wish we chose them years ago instead of other companies who didn't do the job right. First time in years our roof hasn't leaked after it was fixed. We had it done many times! This company couldn't be any better! We tell everyone how wonderful they are. I would be a very proud owner of my employees and the salesman Larry Ebbs and Igor as well as Dina and others on the crew. Thank you ! Thank You , Thank You, Thank You, Igor made our house pretty again!
About as good a product as I've ever purchased. They had aluminum before any of the ones now advertising on television. Great work and lots of great comments from people seeing my roof. At some point, I'd like to do the same on the shed. Snow and ice come right off. It is not a maybe, slides right off in large sections. Positive: Professionalism Services: Roof installation
I want to thank you for coming to my home to show me the video, samples, and explain the differences between the Interlock Roofing System and regular roofing shingles. The blue I chose is beautiful and really perks up my old home. It is so comforting to know that it will no longer leak around the dormers. I can now paper and paint my bedrooms with confidence and know that we won’t be ruined by rain. It is so nice to know that I will never have to roof my home again. Thank you again.
If they were in my monetary range I would hire them in a heartbeat. My wife and I loved the product.
Homeowner was short with me and did not want to speak to me at first. I was able to ask the open ended questions and got the reason why he was defensive. They are putting a hold on the project. Currently, homeowner feels they do not need a new roof just yet. He was satisfied with sales presentation but right now is not the time to move forward.
They could improve by coming to fix the issues I suggested. Someone need to come out to fix the issues I had during installation.
