A New England roof gets heavy wet snow, wind-driven rain, months of freeze and thaw, and on the coast, salt air. Here is what an Interlock® aluminum roof does about each.
Snow
Interlock panels weigh roughly 0.4 to 0.7 lb per square foot depending on profile, a fraction of natural slate or concrete tile. That leaves the structure's capacity for what a New England winter puts on it: heavy, wet snow. Smooth aluminum lets snow slide, so we plan snow guards over entries, walkways and the driveway at the quote.
Nor'easters
A nor'easter brings hours of wind-driven rain and gusts that work at loose edges and exposed screw heads. Interlock panels lock to each other on all four sides with the fasteners concealed. Wind resistance is warranted to 120 mph installed to manufacturer specification.
Ice dams
Ice dams form when heat escaping into the attic melts snow that refreezes at the cold eaves. No roof covering stops that on its own, and ice damming is excluded from the material warranty. At the estimate we look at insulation and ventilation with you and tell you what we see.
Salt air
On Cape Cod, the Islands, the North Shore, the Rhode Island and Connecticut shoreline and the Maine coast, salt air corrodes steel fasteners and flashings. Aluminum cannot rust. It forms its own thin oxide layer, which re-forms if the surface is scratched.
Freeze-thaw
Months of freezing and thawing loosen asphalt granules and curl shingles; cedar takes on water that freezes in the grain. An aluminum panel absorbs nothing, so there is nothing in it for the cold to split.
Summer heat
The Alunar® finish uses pigments that reflect much of the sun's near-infrared energy: solar reflectance from 0.25 to 0.55 depending on color and thermal emittance of 0.84. Interlock roofs can cut cooling-energy use by up to 25% compared with conventional dark roofing; actual savings vary. The Alunar® finish is warranted for 30 years.
2,790 Interlock® roofs in Massachusetts since 1999, the most in Brockton, Lowell, Worcester, Plymouth and Quincy: Colonials, Capes, triple-deckers and homes on the coast from the North Shore to Cape Cod.
Panels locked on four sides, and aluminum that cannot rust in salt air.
The look of slate or cedar on an older house. Check your local historic commission's rules before you choose; we bring samples and product documents to that conversation.
Under Chapter 183A the roof is usually common area, so the trustees decide. We can meet the board and price every building.
Massachusetts home improvement contractors must be registered (M.G.L. c. 142A, which also sets up the Guaranty Fund). Our state numbers are in the footer of every page.
728 Interlock® roofs in New Hampshire, the most in Manchester, Derry, Salem and Nashua: from the Seacoast and the Merrimack Valley to the Lakes Region and the White Mountains.
Light on the framing under heavy snow, with snow guards planned at the quote.
They start in the attic. We look at insulation and ventilation with you at the estimate.
Aluminum cannot rust, which matters within reach of salt air.
New Hampshire does not license roofers, so ask any contractor for proof of insurance, a written contract and local references.
649 Interlock® roofs in Connecticut, the most in West Hartford, Hartford, Manchester and Danbury: older Colonials inland and homes along the Long Island Sound shoreline.
Aluminum cannot rust in salt air; panels are locked on four sides against wind.
The look of slate or cedar shake at a fraction of the weight.
A reflective finish in every color; actual savings vary.
Connecticut home improvement contractors register with the Department of Consumer Protection. Our number is in the footer.
389 Interlock® roofs in Rhode Island, the most in Warwick, Cranston, Providence and Pawtucket: from Providence's older neighborhoods to homes around Narragansett Bay and along the coast.
Aluminum cannot rust, on the bay or off it.
Panels locked on four sides; wind warranted to 120 mph installed to manufacturer specification.
Check your local historic district commission's rules first; we bring samples and documents.
Rhode Island contractors register with the Contractors' Registration and Licensing Board. Our number is in the footer.
399 Interlock® roofs in Maine, the most in Lewiston, Sanford, Brunswick and South Portland: long winters inland and salt air on the coast.
Light on the framing under snow, with snow guards planned at the quote.
Aluminum cannot rust, on the water or off it.
Nothing in an aluminum panel to crack, curl or take on water.
Maine does not license roofers. We hold a Maine Transient Seller registration; the number is in the footer.
81 Interlock® roofs in Vermont, the most in Essex Junction, Burlington, Rutland and Barre: ski country, farmhouses and some of the longest winters in New England.
Light on the framing, so the structure's capacity goes to the snow, not the roof.
One profile and color across every building on the property.
They start in the attic. We look at insulation and ventilation with you.
Our Vermont registration number is listed in the footer with our other state numbers.

The collection
The look belongs to your home. The performance belongs to the metal. Every profile needs a minimum 3/12 roof slope.
A composed silhouette
The formal character of slate at a fraction of the weight, in aluminum that cannot rust.
Familiar warmth
The look of a cedar roof, with nothing to rot, split or take on water in the grain.
Deep shadow lines
Hand-split texture and depth: the usual replacement when a cedar shake roof has had its last re-treatment.
Sculpted, not heavy
The barrel-tile silhouette without the weight of concrete or clay.
Clean lines
Clean vertical lines for a modern home or a cabin, in the same aluminum.
A living metal
Copper weathers over time. Usually a bay, a porch or a turret rather than a whole house.
Where we've worked
We install the Interlock® aluminum roofing system on homes, condominium complexes and churches across Massachusetts, New Hampshire, Connecticut, Rhode Island, Maine and Vermont: interlocking panels locked on four sides with the fasteners out of the weather, made in North America by Interlock Roofing, and installed by our own New England company from our office in Walpole, Massachusetts.
Completed Interlock® roofs by state and by town, from our job book. Each state has its own page, and so does each town with three or more of our roofs.
We serve Massachusetts, New Hampshire, Connecticut, Rhode Island, Maine and Vermont from Walpole, MA. Not sure we reach your town? Ask us.

Why this system, in New England
Asphalt in New England
Freeze-thaw, nor'easter wind and summer heat work on asphalt shingles every year: granules loosen, edges curl and tabs lift. An Interlock roof has no granules to lose and no tabs to lift, and its panels lock to each other on all four sides.
Older homes
Interlock's Slate, Cedar Shingle and Shake profiles keep the look on a Colonial, a Cape, a Victorian or a farmhouse at roughly 0.4 to 0.7 lb per square foot, a fraction of natural slate. In a historic district, check your local commission's rules first; we bring samples and product documents to that conversation.
Snow and nor'easters
Smooth aluminum lets heavy, wet snow slide rather than sit, and we plan snow guards over entries, walkways, decks and the driveway at the quote. The panels lock on four sides with concealed fasteners; wind resistance is warranted to 120 mph installed to manufacturer specification.
One company
We plan, price and install every roof ourselves. The manufacturer's Guardian Lifetime Limited Material Warranty comes with it, and our service team is here in New England.
Recycled
And the last tear-off your house is likely to need.
The metallurgy, coatings and test reports are the manufacturer's to explain: interlockroofing.com ↗
Made in North America
Every Interlock® panel we install is manufactured by Interlock Roofing, the maker of the Interlock® roofing system, at its plant in Delta, BC.
Interlock Metal Roofing (New England) Inc. was founded in 1999 and works from Walpole, MA, serving all six New England states. 27 years in business.
We plan, price and install your roof ourselves, as the certified and exclusive Interlock® roofing contractor for New England. After the install, our New England service team is the one you call.
Upcoming shows
Lift a panel, feel the weight, see every color in daylight and ask the people who install it. Come find us at a show near you.
Yes. We install Interlock® aluminum roofs in Massachusetts, New Hampshire, Connecticut, Rhode Island, Maine and Vermont, from our office in Walpole, Massachusetts. Each state has its own page on this site, with the towns we have roofed there.
Sometimes. A single layer of asphalt can be roofed over only if an inspection finds it suitable; cedar shingles and shakes, concrete tile and natural slate always come off first. We check at the estimate and tell you which applies to your roof.
No roof covering stops ice dams on its own. They form when heat escaping into the attic melts snow that refreezes at the cold eaves, and ice damming is excluded from the material warranty. At the estimate we look at your insulation and ventilation with you and tell you what we see.
The manufacturer's Guardian Lifetime Limited Material Warranty covers the material and finish for the original purchaser for as long as they own the home, and it can be transferred once; the second owner is covered to 50 years from substantial completion. Workmanship is not part of that warranty.
Often, but the decision belongs to your local historic district commission, not to us. Check its rules before you choose a profile. Slate, Cedar Shingle and Shake keep a traditional look, and we can bring samples and product documents to the review.
Book a free consultation on Zoom or at your home. We go through profiles and colors with you, measure the roof, and you get a written price after your roof consultation.
