Metal roofing in West Lebanon: installed once, warranted for life
Every asphalt roof in West Lebanon 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
West Lebanon 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 West Lebanon
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 West Lebanon homeowners say
★★★★★“Clean up all of the little shards and pieces of aluminum shingles that were trimmed. We are detecting a slight decrease in the strength of our cell phone signal. We had asked Ed about this and he said that the roof would not interfere with our reception, but it appears to have affected it. We were lead to believe that we could use our credit card for the entire price of the job. However when we spoke with Deana and read our contract we discovered that it had an asterisk and very fine print about the fact that use of the card was limited to the deposit.”
“We are very pleased with our new Interlock Roof! We live in a house that was built in 1886, and the new roof looks just like slate. This was the perfect choice for our home, and we look forward to enjoying it for many years to come.”

Will a metal roof handle West Lebanon 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. West Lebanon averages roughly 57 inches of snow and 108 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 West Lebanon 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.
