Metal roofing in Rochester: installed once, warranted for life
Every asphalt roof in Rochester 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 New Hampshire homes
Rochester 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 Rochester
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. New Hampshire requires no state roofing license — judge any contractor here by what is verifiable: we're fully insured, US EPA Lead-Safe certified (NAT-34864-3), and BBB A+ accredited since 1999.

The Interlock system carries a warranted 120 mph wind rating with four-sided panel interlock. And with 90 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 Rochester homeowners say
★★★★★“High quality workmanship. Notify us of changes before the installation. Specifically installed box vents instead of the agreed upon ridge vent.”
★★★★★“My two prior asphalt shingle roofs curled, cracked, grew moss, had black streaks, and generally looked terrible in 10-15 years each. I was so done with asphalt roofs.”
★★★★★“I found quite a few nails in my driveway after completion. The crew didn't get a chance to finish cleaning up on the final day because of darkness and a huge rainstorm started. This wasn't their fault and was not a big deal. The roof is absolutely beautiful. It exceeds my expectations!!!”
★★★★★“The one and only problem I had with anything was their help not speaking English well. It makes things kind of difficult. They were excellent, they really were, but it is very hard to communicate with them. We just had a flash hail storm the other day. It tested our roof, and it did very very well. The hail was almost golf ball sized, and it lasted for about five minutes. We didn't hear the rain, but boy did we hear that hail. It sounded like machine guns going off against the walls and roof. I haven't seen hail like that since I left Texas. There were no dents in the roof, and there were no blemishes. It held up beautifully.”

Common questions in Rochester
Who installs metal roofing in Rochester, NH?
Interlock Metal Roofing – New England installs lifetime interlocking aluminum roofing in Rochester, New Hampshire — metal shingle, slate, cedar shake and standing seam profiles with concealed fasteners, a warranted 120 mph wind rating, and the Guardian lifetime limited warranty, transferable once.

Yes — 3 documented installation photos in Rochester itself, plus verified homeowner reviews from Rochester. Every photo on this page is a real Interlock roof — no stock photography.
Will a metal roof handle Rochester 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. Rochester averages roughly 60 inches of snow and 90 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 Rochester estimate; the roof's contribution is less snow sitting at the eaves and no exposed seams for meltwater to work through.
Are you licensed and insured in New Hampshire?
New Hampshire requires no state roofing license — judge any contractor here by what is verifiable: we're fully insured, US EPA Lead-Safe certified (NAT-34864-3), and BBB A+ accredited since 1999.
