Interlock® Aluminum Roofing — all-climates performance specs for Gilmanton Iron Works, 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 were very nice and I would like to get back to them. I am going to contact you so I can talk to you some more. I would recommend Interlock Roofing, they were nice and thorough.
my only concern was that a new skylight was placed as known previously by all. Previous roofing was removed and left a bit of a gully. Interlock just showed up and put on the roof with no discussion with me that it would leave a gully around the window. It would seem to me that the professional thing to do would be to contact me, inform me and discuss possible resolution rather than just put the roof down and see what happens.
Mike was awesome. Very pleasant to deal with.
None - well done All good.
You have a good product and everything but the pay back wouldn't be there because I'm to old. If I was 20-30 it would be a good pay back but I am 71 years old.
They could have improved in having the salesperson and foreman have a sit down so they are not disconnected and have the same information. Also, they should have workers that understand and comprehend English.
