New England roof replacement

What replacing a roof with us involves

It starts with one visit, at your house or on Zoom to begin. We measure the roof, look at the deck and framing where we can, go through profiles and colors with you, and you get a written price after your roof consultation. Anything that needs attention underneath goes into that written quote, not into a change order later.

On install day the Interlock® aluminum system goes on: panels that lock to each other on all four sides with the fasteners concealed, so there is no exposed screw head or loose edge for nor'easter wind, driven snow or rain to work on.

Tear-off or roof-over?

Cedar shingles and shakes, concrete tile and natural slate always come off. A single layer of asphalt shingles can sometimes be roofed over, but only if our inspection finds the roof suitable: no rot, no soft decking, nothing trapped underneath that should come out. If it isn't suitable, the tear-off is in the written price from the start.

Replacing asphalt, cedar or slate

Most of our work replaces asphalt shingles on Colonials, Capes, ranches and triple-deckers. Interlock's Slate, Cedar Shingle, Shake, Mediterranean Tile and Standing Seam profiles give you the look you want at roughly 0.4 to 0.7 lb per square foot, a fraction of the weight of slate or concrete tile. Every profile needs a minimum 3/12 roof slope.

We install one roofing system. We don't install asphalt shingles, so if you're comparing us with an asphalt re-roof, you're comparing a roof you'll replace again with one that shouldn't need it.

In a historic district, check your local historic district commission's rules before you choose a profile and color. We bring samples and product documents you can take to that review.

Built for a New England winter

Nor'easters, heavy wet snow, wind-driven rain and long freeze–thaw seasons are what wear a roof out here. Aluminum absorbs no water, so there is nothing for freeze–thaw to split, and the panels shed snow rather than hold it. Where snow sliding off would land on an entry, a deck or a walkway, we plan snow guards at the estimate.

Ice dams come from heat escaping into the attic and from ventilation, not from the roof covering, and no roof prevents them on its own. We look at your attic ventilation and insulation with you at the visit. On the coast, aluminum does not rust, which matters in salt air from Cape Cod to the Maine shore.

Check any roofer before you sign

In Massachusetts, home improvement contractors must register with the state under M.G.L. c. 142A, and under 201 CMR 18.00 a contract over $1,000 must be in writing and show the contractor's registration number, which also goes on the building permit. Connecticut requires home improvement contractors to register with the Department of Consumer Protection; Rhode Island registers contractors through its Contractors' Registration and Licensing Board. New Hampshire has no state roofing license and Maine has none either, so in those states check insurance, references and the written contract.

The warranty, in plain language

The manufacturer's Guardian Lifetime Limited Material Warranty covers material and finish for the original purchaser for as long as they own the home, and transfers once: the second owner is covered to 50 years from substantial completion. Workmanship is excluded from that warranty; our installation is covered separately by our 10 Year Limited Labor Warranty. Ice damming is a stated exclusion of the material warranty. Read the full terms before you sign.

Wind resistance is warranted to 120 mph when installed to manufacturer specification.
