Interlock® Aluminum Roofing — all-climates performance specs for Amherst, 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:
Interlock installers were great to deal with. They completed the job in half the time that was quoted. The one minor discrepancy I found two months after installation was fixed by an Interlock representative less than twelve hours after reporting it. The higher cost of an interlock roof has been worth every penny and I’m not even through my first winter yet.
We love the stylish new look our house got with the Metal Slate Roofing and the longevity Interlock Roof System offers. Although the roof is made of aluminum, the design makes the roof look as if it was traditional slated roof.
Interlock Roofing could have improved because it took way too long from the time we signed the contract to the time they started installing the roof.
Interlock Roofing could have improved because it took way too long from the time we signed the contract to the time they started installing the roof.
The salesman was very decent and knowledgeable.
I think the salesperson could be a little more specific when talking with the customer.
Communication between customer and work crew. Heads up on start and stop time. I took time off from work to be here.
