Interlock® Aluminum Roofing — all-climates performance specs for Northfield, New Hampshire
| 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:
They got us scheduled earlier than expected, which was great. They did the entire roof in a day and a half, and they cleaned up after themselves, they worked fast, were very nice, and I highly recommend them to anyone. They could have improved with my understanding of the expectations throughout the project; it could have been better explained. they were great scheduled early, squeaky clean when they left.
It is very hard to be on the roof on a hot summer day. I felt sorry for the guys that were up there. I felt for them. It is very hot and it is a rough job. I don't know if they could improve that for their employees. We only had one problem with one of the skylights not opening but they fixed that immediately. I called on a Tuesday and they were here Thursday. I have given several people information about the company. We are so happy with the roof.
They do excellent work.
The only real problem we had was in trying to communicate with the crew. It seemed as if with the bulk of them English was not their strong language.
It was a great experience.
You should get away from the whole sales pitch and let your product sell itself, I was turned off when, by the end of the pitch he had dropped the price 40 percent. That kind of sales just doesn't feel honest.
Better communication and adhering to schedules.
