Metal roofing in Nashua: installed once, warranted for life
Every asphalt roof in Nashua 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
Nashua 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 Nashua
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 Nashua homeowners say
★★★★★“They were very prompt and attentive. They got it done quickly.”
★★★★“You're company was the only other company that we considered.”
★★★★“David was fantastic. If we could do business with Interlock we would. Especially based on his professionalism and quality of service. The interest rate though made the project too far outside our price range to consider.”
★★★★★“Communication - between Larry Ebbs, Inside Sales and Production folks. Negatives - 1. Larry was certain that I had one layer of roofing - this was incorrect.”

Will a metal roof handle Nashua 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. Nashua 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 Nashua 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.
