Interlock® Aluminum Roofing — all-climates performance specs for East Derry, New Hampshire

Spec / RatingClimate / 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 4Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes.
Snow & ice performance: interlocking, shedding profileHeavy 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 systemHigh heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation.
Moss / algae resistance: smooth coated surfaceWet 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+ yearsLong-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments.

Review: June 23, 2014Completion: March 28, 2014

I would not only recommend the product from Interlock Roofing but I would also recommend the installation crew to anyone! I couldn't be more pleased with how my project turned out, the roof is beautiful! I was worried about the new roof being noisy, but it is quieter than my old roof and I can even sleep through major thunderstorms! I was worried about the possibility of an unprofessional installation crew, but my salesperson assured me all of the Interlock Roofing crews are professional in every way and he was right! I wouldn't change anything about my experience with Interlock Roofing because they did a fantastic job!

★★★★★
Review: March 10, 2018Completion: February 12, 2018

I would have liked less of a wait time but once the job was completed it was worth it for the quality product we received. The roof is excellent and all of the work was completed in 3 days which was very impressive. It improved the appearance of our home and it is awesome to know we won't have to worry about our roof ever again.

Well it was the date of the scheduling other than that once they got here it was a whirlwind. We still have the yard sign.

★★★★★
Review: December 10, 2015Completion: October 19, 2015

The project cleanup could have been a little better. There was some debris left in our yard. We have a dog so we were concerned about nails being left in the yard. It wasn't horrible or anything, but it could have been better.

★★★★☆
Review: February 24, 2015Completion: February 24, 2015

Interlock Roofing was very professional. I have no problems with the company at all. I don't think the product is bad, I just think the cost is too high. Interlock Roofing said the cost is in the guarantee is good but you never if a guarantee is good until something bad happens.

★★★★☆
Review: October 26, 2022Completion: September 22, 2022

Debris management was the primary area for improvement.
