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

What Chelmsford homeowners say
★★★★★“Very happy with the product, the quality of the work and everyone involved with making my project go smoothly.”
★★★★“I would recommend Interlock if the friend is particularly interested in a metal roof and understands the investment The team should stop work by sunset”
★★★★★“Our new roof looks fantastic! Interlock delivered everything they promised -- the work crew was excellent, and communicating with Interlock throughout the project was easy. We couldn't be happier with the results. Since solar panels are becoming more commonplace, I encourage Interlock to anticipate customers' needs in this area and improve how they work with solar installation companies. The roof looks amazing, and we've gotten a lot of compliments on it -- thanks so much!”
★★★★★“Positive: Responsiveness, Punctuality, Quality, Professionalism, Value Services: Roof installation”

Will a metal roof handle Chelmsford 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. Chelmsford averages roughly 48 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 Chelmsford estimate; the roof's contribution is less snow sitting at the eaves and no exposed seams for meltwater to work through.
