Metal roofing in Westport: installed once, warranted for life
Every asphalt roof in Westport is on a 15–20 year replacement clock. An Interlock aluminum system ends it: one installation, four-way interlocked panels with concealed fasteners, a warranted 120 mph wind rating and UL 2218 Class 4 impact rating — and the Guardian lifetime limited warranty, which covers you for as long as you own the home and transfers once to the next owner.
Metal shingles & aluminum roofing profiles for Massachusetts homes
Westport homeowners choose from shingle, cedar shake, slate and standing seam profiles pressed in aluminum — the character New England architecture expects, in Alunar®-coated colors warranted for 30 years. Aluminum can't rust the way steel can, which matters where roofs live under snow for months. "Class A Fire Rated Available." Full product specifications live with the manufacturer: Interlock aluminum roofing systems.
Choosing a roofing contractor in Westport
Ask every contractor the same five questions: how panels attach (clips, single tabs, or four-sided interlock), whether fasteners are exposed, what the coating actually is, whether the warranty is manufacturer-backed and transferable, and how many metal roofs — specifically metal — the crew installed last year. Our answers are on this page and in writing at your estimate. Licensed and insured in Massachusetts (Massachusetts — MA 139640) · US EPA Lead-Safe certified · BBB A+ since 1999.
Westport weather, by the numbers

Peak gusts here have exceeded hurricane force — the Interlock system's warranted 120 mph wind rating and four-sided panel interlock are engineered for exactly this. And with 64 freeze–thaw cycles in a typical year, concealed fasteners matter: there are no exposed gaskets or fastener heads for that cycle to age, back out, or leak through.

What Westport homeowners say
★★★★★“Our recent experience with the team at InterLock Roofing was exceptional. Their Sales expert Chris L. worked with us to explain the features, advantages, and warranty of their lifetime aluminum shingle roof system. We worked together to document the complete scope of work before the work began. (The existing asphalt shingle roof, installed in 2006, had been leaking in several locations for year's - damaging our ceilings and hardwood flooring). Wilson P. (Site Foreman) and his install team were hard working, professional, and extremely thorough.”
★★★★★“The team at InterLock replaced a asphalt shingle roof on our house. The old roof was installed in 2006 and had been leaking in a few places for years. Damaging ceilings and hardwood floors. Our modular home had several obvious gaps in the roof deck. InterLock stripped the existing roof down to the roof deck. They replaced all damaged decking and removed all the gaps before installing their lifetime aluminum shingles. The team overcame several challenges and did all the specified work to our complete satisfaction. Having all the required materials on site and readily available when needed. Great team and excellent product.”
“Their work was performed with a true sense of professionalism. Our new roofs look great! We had many compliments from our neighbors and friends. On the second day that the sign was put on the front lawn, a woman knocked on the my front door for information about the roof. She loved it! I gave her a card. We are very satisfied with our new roofs and happy that we are guaranteed we will never have to replace it again.”

Will a metal roof handle Westport snow and ice dams?
The interlocked aluminum surface sheds snow far more readily than asphalt, and every panel locks to its neighbors on all four sides with no exposed fasteners. Westport averages roughly 26 inches of snow and 64 freeze–thaw days a year (10-year averages) — exactly the cycle that works exposed fasteners loose on other systems. Ice dams themselves start in the attic — heat loss and ventilation — which we assess at every Westport estimate; the roof's contribution is less snow sitting at the eaves and no exposed seams for meltwater to work through.
