Roofing in Brewster, MA: Costs, Permits and What to Expect

Brewster is cedar-shingled capes under oaks and pitch pines, a long run of bayside houses along Route 6A and a historic district that covers much of the town. That last part changes how a roof replacement is planned, so it is worth understanding before you pick a shingle.

The building permit comes from the Brewster Building Department and is filed through the town's OpenGov portal (brewsterma.portal.opengov.com) as a building permit, which includes express permits for roofs. The portal asks for an agent authorization or homeowner exemption, a debris affidavit and a workers' compensation affidavit. On the fee schedule effective March 1, 2026, a one- or two-family express permit for a roof is $50 per category per structure, plus a $25 deposit per application, and fees triple if work starts before the permit is issued. The town does not issue permits when property taxes are in arrears.

Most of Brewster falls inside the Old King's Highway Regional Historic District, which the Building Department administers with the town's OKH committee. Under the district regulation (972 CMR 3.00), replacing shingles with the same existing material is ordinary maintenance and needs no certificate. Architectural wood-style asphalt shingles in black, gray or weatherwood, and natural cedar, qualify for a certificate of exemption without a hearing, as long as they suit the house, show no more than 5 inches of exposure and a sample is submitted. Other materials or colors should be expected to go to the committee.

Massachusetts treats a roof replacement as permitted work. The residential code (780 CMR, 10th edition) lists what is exempt from a permit, and re-roofing is not on that list. The contractor needs a Construction Supervisor License that covers roofing and, on an owner-occupied home, a Home Improvement Contractor registration, and the HIC number goes on the permit application.

The code also sets the floor for how the roof is built. Ice barrier underlayment is required everywhere in the state, running from the eave to at least 24 inches inside the exterior wall. A new roof cannot go over two existing layers, or over one that is wet or deteriorated, and drip edge is required at eaves and rakes. Shingles have to carry a wind rating matched to the town's design wind speed.

Brewster's design wind speed in the state code is 130 mph, one of the higher values on the Cape. At that speed shingles have to be labeled ASTM D7158 Class G or H, or D3161 Class F. Under heavy tree cover the bigger day-to-day problem is moisture: shaded roofs stay damp, valleys fill with needles and moss takes hold on the north side, so algae-resistant shingles and proper ventilation earn their keep here.

What a roof costs comes down to a handful of things you can see in a written estimate: the size of the roof in squares, the pitch, how many layers come off, how much of the deck is soft once it is open, the flashing at chimneys, walls and skylights, ventilation corrections, and the shingle system itself. The permit is a small line next to those. Any estimate worth signing lists them separately, including the price per sheet for deck replacement, so the number does not move once the old roof is off.

Under the Massachusetts home improvement law (MGL c.142A), a contract over $1,000 has to be in writing, with the contractor's registration number on the first page, start and finish dates, the materials, the total price and the payment schedule. The deposit cannot be more than one third of the price, or the cost of special-order materials, and a contract signed at your home comes with three days to cancel.

Who pulls the permit matters. If the registered contractor pulls it, you are covered by the state Guaranty Fund, which pays up to $25,000 on an unpaid judgment against a registered contractor. If the homeowner pulls the permit, that protection is gone. We pull the permit on every roof we do.

Brewster is about 25 minutes from our Hyannis office. When a house is in the OKH district we sort out the certificate or exemption before the permit, so the schedule does not stall halfway, and most roofs are torn off and finished in one to three days.
