Interlock® Aluminum Roofing — all-climates performance specs for Dunstable, Massachusetts

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: October 22, 2021Completion: September 27, 2021

Our new roof looks fantastic! Interlock delivered everything they promised -- the work crew was excellent, and communicating with Interlock throughout the project was easy. We couldn't be happier with the results. Since solar panels are becoming more commonplace, I encourage Interlock to anticipate customers' needs in this area and improve how they work with solar installation companies. The roof looks amazing, and we've gotten a lot of compliments on it -- thanks so much!

Review: December 9, 2015Completion: December 9, 2015

Jeff is a good sales guy and understands customers. Let him decide if the customer needs a long visit, a second visit, etc. Give him flexibility in the discount for signing immediately versus dropping things off. I think he'll do a great job for you.

Review: May 15, 2015Completion: April 20, 2015

The two installers who came out the first day, one spoke no English and the other spoke very poor English. The second day was better. I like the company and I've had many good compliments about the roof.

★★★★★
Review: September 21, 2016Completion: August 30, 2016

I wasn't happy with the financing. I wasn't sure if I was going to be able to swing it because the interest rate changed from what was given to me over the phone (which was 10.8) to what was on paper (12+ %) The interest rate was high and I felt pressured. I didn't like the pressure. They should send the paperwork with communication regarding the interest rate instead of the way it happened.

★★★★
Review: November 17, 2022Completion: November 10, 2022

I would recommend Interlock if the friend is particularly interested in a metal roof and understands the investment The team should stop work by sunset

★★★★
Review: July 26, 2022Completion: April 22, 2022

The quality of the work in the trimming and finishing around the edges, for the most part, was good, but there were several areas where they had to come back and fix. The first day the crew lead was there, but after that there was no one I could talk to to address concerns due to the language barrier. In general, I am satisfied with the work. I received compliments on the roof. I expected to be taken care of more for the cost that was paid this is a high-end product and I didn't receive it.
