Metal roofing in Warner: installed once, warranted for life
Every asphalt roof in Warner 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
Warner 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 Warner
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 Warner homeowners say
★★★★★“I never had a roof replaced before, but I am very happy with it. They did an excellent job.”
★★★★“Our first Interlock roofing project was a great success which led us to use them again. Unfortunately, the second project did not go as smoothly and we are definitely not as pleased with the process this time.”
“We chose Interlock to install a much needed new roof on our 200-year-old farmhouse in Warner, New Hampshire which serves as our year-round vacation getaway. From the moment David showed up to meet with us through the final completion of the project a few weeks ago, we knew that we had made the right decision and that our project was in good hands. We never once felt pressured even though we took longer than expected to complete some preliminary repairs to a porch roof before the project could begin. When we did finally call to say that we had completed our work and were ready to go, they had a work crew on site in less than a week! More amazing is that they completed their work of stripping the old asphalt, installing a plywood deck, and re-roofing a large old house where nothing is truly square in five days and, other than the evidence of a brand new gray slate roof on our house, one would never know that anyone had even been there. The crew left our property cleaner than it was before they arrived. They even cleaned up a pile of roofing debris we had left behind following our re-roofing project. Throughout the project, David and Jennifer, in the office, were always available to answer our questions. From selecting the right roof to arranging to finance, to completing the project in a timely fashion, we could not be happier with the total interlock experience. We are highly satisfied with the result and are already looking forward to having Interlock install a new roof on our adjoining barn in the near future.”
★★★★“Our first Interlock roofing project was a great success which led us to use them again. Unfortunately, the second project did not go as smoothly and we are definitely not as pleased with the process this time.”

Common questions in Warner
Who installs metal roofing in Warner, NH?
Interlock Metal Roofing – New England installs lifetime interlocking aluminum roofing in Warner, 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. Headquartered in Walpole, MA; serving Warner since 1999.
Do you have examples of your work near Warner?
Yes — documented installations in neighboring New Hampshire towns, plus verified homeowner reviews from Warner. Every photo on this page is a real Interlock roof — no stock photography.
Will a metal roof handle Warner 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. Warner averages roughly 65 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 Warner 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.
