- Interlocking panel system tested to 193+ km/h (120+ mph) to resist severe windloads from Nor’easters and strong frontal systems impacting Strafford County.

- Low-maintenance, fully recyclable aluminum construction resists rot and substrate degradation common with repeated wetting and freeze cycles.
- Backed by a Lifetime-Limited transferable warranty to protect long-term investment and support property resale in Middleton and throughout Strafford County.

Interlock® Aluminum Roofing — all-climates performance specs for Middleton, 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:
The people were very courteous and the product is great. the people there were very professional and polite. We were happy with everything.
The one and only problem I had with anything was their help not speaking English well. It makes things kind of difficult. They were excellent, they really were, but it is very hard to communicate with them. We just had a flash hail storm the other day. It tested our roof, and it did very very well. The hail was almost golf ball sized, and it lasted for about five minutes. We didn't hear the rain, but boy did we hear that hail. It sounded like machine guns going off against the walls and roof. I haven't seen hail like that since I left Texas. There were no dents in the roof, and there were no blemishes. It held up beautifully.
High quality workmanship. Notify us of changes before the installation. Specifically installed box vents instead of the agreed upon ridge vent.
I was not thrilled with how pushy the salesperson was. I can not say enough about how good the installation crew was.
They did everything to my satisfaction. no
Naz, worked for hours non stop doing the repairs , He had a lot of stamina and knowledge on how to remedy any damage . Afterwards he showed me the finish product , I was and still am amazed as to the quality of his works
I recommend the material but am not all that wild about the crew. I think there could have been more of an effort to keep to the agreed upon time.
I think communication during the project was terrible- a lot of miscommunication. We were told one thing and the complete opposite happened. I think all employees need to be on the same page and the person relating the message to the customer should know exactly what is going on. It does not make me confident in the company when this was happening to me. While overall I am happy with the product- and am not thrilled with the customer service.
