Interlock® Aluminum Roofing — all-climates performance specs for Seabrook, 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:
It was just very positive. We were very impressed.
I can tell you that your guy was not pushy. I had another company come out and their guy was the pushiest guy I've met. I respect the fact that David didn't call or harass me everyday.
They fell short in the area of communication. The person who was subcontracted dropped of the waste disposal unit early in the morning and he have a huge problem with that because we were not notified. We have underlying issues with the dumpster people. They did not inform us that they were going to arrive. We have issues with their inconsiderate arrivals and it was very unfortunate.
I would take it in a minute but we can't afford it.
Fast response to a small problem.
The only thing I would change is to tell people how long the appointment will take. Thanks
Everybody was polite. I called back for minor repairs which they came out and addressed.
1. SPEAK ENGLISH! It was nearly impossible to communicate with the crew. Most of the time there was no one on site who spoke English. Follow up was weak. I signed off with a crew that spoke no English late on a Friday after they had worked long hours, and got no further follow up until I called in with a problem
