Metal roofing in Dover: installed once, warranted for life
Every asphalt roof in Dover 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
Dover 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 Dover
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 93 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.

Common questions in Dover
Who installs metal roofing in Dover, NH?
Interlock Metal Roofing – New England installs lifetime interlocking aluminum roofing in Dover, 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.

Do you have examples of your work near Dover?
Yes — 3 documented installation photos in Dover itself, plus verified homeowner reviews from Dover. Every photo on this page is a real Interlock roof — no stock photography.
Will a metal roof handle Dover 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. Dover averages roughly 46 inches of snow and 93 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 Dover 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.
