Interlock® Aluminum Roofing — all-climates performance specs for Kalivas Union, 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.

What our customers are saying:

★★★★★
Review: December 2, 2022Completion: November 14, 2022

We had a new metal roof installed on our entire home, and we are very pleased with the quality of the product. Our installation had to be scheduled for after some other work being done on the house, and Interlock was very flexible with our ever-evolving timeline.

★★★★★
Review: May 15, 2025Completion: April 30, 2025

Interlock Roofing just completed roofing our home. Looks great! Experience with Jonathan to Jennifer to Gallo and his workers couldn't have been better. Wished we had done this sooner.

★★★★★
Review: December 7, 2022Completion: November 14, 2022

I am unlikely to recommend Interlock to a friend. I found the sales representative, Jonathan Brown, highly deceptive when pricing the deal. That is simply unacceptable. I did find the installation crew hard working and organized. They did a good job and I appreciated that. I didn't get the idea that there was a lot of supervision, though and some of the installation problems that came up at the end reflected that. I still have some questions about the work. They should provide a port-potty for the crew.

★★★★★
Review: April 7, 2023Completion: March 22, 2023

I would have preferred a crew from Interlock supervising the subcontractors. That way I could have gone to them and asked them to stay on top of the subcontractor's cleanliness

★★★★★
Review: October 27, 2014Completion: September 11, 2014

Our only challenge was the language barrier with the roofing crew. One of the employees could speak very broken English and we cannot speak Spanish so it was difficult to ask questions or discuss concerns directly with the crew. However, a simple phone call to Jennifer Simons at the Walpole office addressed the issue.

★★★★★
Review: May 2, 2017

They were exactly what I thought. I knew they were right there at the top and they pretty much are.
