Interlock® Aluminum Roofing — all-climates performance specs for Canaan, 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.
Warranty: Lifetime-Limited, non-prorated + 50-year transferableLifetime protection + resale value: guarantees long-term material confidence and transfers to future owners.

Review: July 21, 2019Completion: September 28, 2017

Our Interlock Metal roof is all we had hoped it would be! Folks often stop by and ask about it. We direct them to the company with complete assurance that they will be as happy as we are. My photo doesn't capture the bright blue color. When locals give directions that include our home, it is referred to as the "happy house." Every season looks even more beautiful surrounding our home. The men who worked on it could not have been nicer, more thorough, or more patient with us! Service: Roof installation

Review: April 22, 2004Completion: May 3, 2006

We are very pleased with our new Interlock Roof! We live in a house that was built in 1886, and the new roof looks just like slate. This was the perfect choice for our home, and we look forward to enjoying it for many years to come.

Review: October 31, 2016Completion: September 29, 2016

Clean up all of the little shards and pieces of aluminum shingles that were trimmed. We are detecting a slight decrease in the strength of our cell phone signal. We had asked Ed about this and he said that the roof would not interfere with our reception, but it appears to have affected it. We were lead to believe that we could use our credit card for the entire price of the job. However when we spoke with Deana and read our contract we discovered that it had an asterisk and very fine print about the fact that use of the card was limited to the deposit.
