Interlock® Aluminum Roofing — all-climates performance specs for Petersham, Massachusetts
| 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 warehouse manager went out of his way to accommodate my payment related requests. My installer was professional, answering all my questions and providing pictures of each step in the repair process.
The installation crew, lacked in cleanliness and they didn't speak English. The one that was in charge, didn't show up on second day.
Lack of communication, this really should be addressed
Mike the salesman was very knowledgable but his sales approach is much longer and arduous than necessary.
We really liked the looks and how well our friends roof was doing so was hoping...
I have no complaints, this is the 3rd roof I have had done by Interlock and I am very happy with them and their crew.
The quality of the work was beautiful. The process of getting the roof up there, was a nightmare. We had a really hard time during the process. It's not truly a straight answer. I think if there was a way to contact the same person throughout the process so they are familiar with the situation, that alone would help out quite a bit. There was a lot of good and bad.
