Interlock® Aluminum Roofing — all-climates performance specs for Andover, 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:
We chose Interlock to install a much needed new roof on our 200-year-old farmhouse in Warner, New Hampshire which serves as our year-round vacation getaway. From the moment David showed up to meet with us through the final completion of the project a few weeks ago, we knew that we had made the right decision and that our project was in good hands. We never once felt pressured even though we took longer than expected to complete some preliminary repairs to a porch roof before the project could begin. When we did finally call to say that we had completed our work and were ready to go, they had a work crew on site in less than a week! More amazing is that they completed their work of stripping the old asphalt, installing a plywood deck, and re-roofing a large old house where nothing is truly square in five days and, other than the evidence of a brand new gray slate roof on our house, one would never know that anyone had even been there. The crew left our property cleaner than it was before they arrived. They even cleaned up a pile of roofing debris we had left behind following our re-roofing project. Throughout the project, David and Jennifer, in the office, were always available to answer our questions. From selecting the right roof to arranging to finance, to completing the project in a timely fashion, we could not be happier with the total interlock experience. We are highly satisfied with the result and are already looking forward to having Interlock install a new roof on our adjoining barn in the near future.
I never had a roof replaced before, but I am very happy with it. They did an excellent job.

They do excellent work.
Roof removal was not always cautious but the team responded to commentary and improved.
Our first Interlock roofing project was a great success which led us to use them again. Unfortunately, the second project did not go as smoothly and we are definitely not as pleased with the process this time.

Better communication and adhering to schedules.
The original schedule was not communicated or held to very well. I did not want the roof put on after it snowed in Nov. which was 8 weeks after the contract was signed. Consequently it took until July to finally get a jointly agreed upon installation.
