Metal roofing in Portsmouth: installed once, warranted for life
Every asphalt roof in Portsmouth 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 Rhode Island homes
Portsmouth 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 Portsmouth
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. Licensed and insured in Rhode Island (Rhode Island — RI 18345) · US EPA Lead-Safe certified · BBB A+ since 1999.
Portsmouth weather, by the numbers
10-year local averages — the conditions a Portsmouth roof actually has to survive, and what we engineer for.
30″
snow per year
78 mph
peak wind gusts
80
freeze–thaw days/yr
50″
rain per year
Peak gusts here have exceeded hurricane force — the Interlock system's warranted 120 mph wind rating and four-sided panel interlock are engineered for exactly this. And with 80 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.

What Portsmouth homeowners say
★★★“Sloppy clean up. Numerous materials left in yard and driveway including an empty tube of sealant, an empty soda can, pieces of roofing materials, and nails and screws left in drive way. I just hope I have found all of them.”
★★★★★“We are pretty happy, and we should be okay as long as there aren't any issues down the road.”
★★★★★“The work crew made a good effort to clean up at completion, but I have found, and occasionally find more nails in the perimeter. This is significant since the drive way goes around the house and is close to the house and roof edge. I would recommend a follow up sweep of the area with a magnetic sweeper.”
★★★★★“It has been a year since I had my Interlock roof installed and I have meant to write this letter. I am glad I waited because I discovered additional advantages to the roof system by Interlock. I initially was impressed by the planning. Mr. Baldassari explained the roof, brought samples, how it would be installed on my house and interface with existing gutters. He also provided local addresses of Interlock roofs that I could view which was very helpful. During the planning process, he recommended changes I may not have thought of but would eliminate future costs and problems.”

Will a metal roof handle Portsmouth 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. Portsmouth averages roughly 30 inches of snow and 80 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 Portsmouth estimate; the roof's contribution is less snow sitting at the eaves and no exposed seams for meltwater to work through.
