Metal roofing in Concord: installed once, warranted for life
Every asphalt roof in Concord 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
Concord 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 Concord
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.

What Concord homeowners say
★★★★★“They got us scheduled earlier than expected, which was great. They did the entire roof in a day and a half, and they cleaned up after themselves, they worked fast, were very nice, and I highly recommend them to anyone. They could have improved with my understanding of the expectations throughout the project; it could have been better explained. they were great scheduled early, squeaky clean when they left.”
★★★★★“The only real problem we had was in trying to communicate with the crew. It seemed as if with the bulk of them English was not their strong language.”
★★★★★“It is very hard to be on the roof on a hot summer day. I felt sorry for the guys that were up there. I felt for them. It is very hot and it is a rough job. I don't know if they could improve that for their employees. We only had one problem with one of the skylights not opening but they fixed that immediately. I called on a Tuesday and they were here Thursday. I have given several people information about the company. We are so happy with the roof.”
★★★★★“I think that Interlock Roofing could use people who speak a little more English. We had a problem with communication at times. The foreman was good but if he wasn't right there then we had a little problem with understanding the workers on the installation crew.”

Common questions in Concord
Who installs metal roofing in Concord, NH?

Will a metal roof handle Concord 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. Concord averages roughly 46 inches of snow and 98 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 Concord 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.
