Metal roofing in Westwood: installed once, warranted for life

Every asphalt roof in Westwood 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 Massachusetts homes

Westwood 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 Westwood

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 Massachusetts (Massachusetts — MA 139640) · US EPA Lead-Safe certified · BBB A+ since 1999.

Westwood weather, by the numbers

10-year local averages — the conditions a Westwood roof actually has to survive, and what we engineer for.

30″

snow per year

84 mph

peak wind gusts

84

freeze–thaw days/yr

47″

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 84 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.

Roofing in Westwood

Westwood's mature tree canopy is beautiful and hard on asphalt — shade holds moisture, moss follows, and shingles age ahead of schedule. An aluminum surface gives moss nothing organic to grip. Six Westwood homeowners have left verified reviews of their installations.

What Westwood homeowners say

★★★★★

“Yes. It just looks so good and you will never have to replace it. As mentioned above, communication, especially if there is a scope of work change, should be done as soon as possible. I really love my new roof. The cost was more than twice what I would have paid for a high-end "architectural" asphalt roof; but the longevity and look of the new roof is worth it. I know I will never have to think about my roof ever again. I have gotten many complements already from our neighbors, and many think it's a real slate roof (it looks that good).”

Colin C. · Westwood, MAGuildQuality
★★★★★

“Placement of materials: On the contract sheet, it stated materials would be located on the driveway but I was told or led to understand by the salesman just prior to signing that they would be placed on a palate on my lawn to the right or left of my driveway. They were instead placed right in front of my garage doors so I had no ingress/egress through my garage for eleven days. One thing verbally intimated while another written down, and of course the written instruction prevailed. Should have been clearer about this, especially with a small driveway.Also I could have used a reminder to run an electrical cord out the window in the phone call I got the day before the first day of installation. I'm preoccupied (like everybody else) and that would have helped.”

Rick G. · Westwood, MAGuildQuality
★★★

“This would depend on if and when we find a resolution and/or compromise.”

Caron and Williams C. · Westwood, MAGuildQuality
★★★★★

“The project itself was fine. The dumpster was placed infront of one of garage doors so we couldnt use the car for the duration of the project. That wasn's a major issue as we have another car just an inconvienence Very happy thus far, provided we have no issues with the snow staying on the roof, if it slides off as advertised, I'll be estatic.”

Domenic and Silvia S. · Westwood, MAGuildQuality

Common questions in Westwood

Who installs metal roofing in Westwood, MA?

Interlock Metal Roofing – New England installs lifetime interlocking aluminum roofing in Westwood, Massachusetts — 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 Westwood since 1999.

Do you have examples of your work near Westwood?

Yes — 5 documented installation photos in Westwood itself, plus verified homeowner reviews from Westwood. Every photo on this page is a real Interlock roof — no stock photography.

Will a metal roof handle Westwood 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. Westwood averages roughly 30 inches of snow and 84 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 Westwood estimate; the roof's contribution is less snow sitting at the eaves and no exposed seams for meltwater to work through.
