The short answer

Who are the roofers on Cape Cod?

Coast Carpentry Home Group is a Cape Cod roofing contractor based at 14 Parker Rd in Osterville. We replace and repair roofs in all fifteen Barnstable County towns: architectural asphalt shingles, red cedar, standing seam metal and rubber membrane for low-slope sections. Our own crews tear off, repair the deck, install ice and water shield where the Cape needs it, and finish most residential roofs in one to three days.

What we roof

Every roof type you will find on a Cape house.

Asphalt is most of the work. Cedar, metal and rubber are the rest, and we install all four with our own crews.

Asphalt shingle roof replacement

Architectural shingles rated for high wind, nailed to the manufacturer's coastal pattern, over a full ice and water shield at eaves, valleys and penetrations. One to three days on most homes.

Roof repair and leak diagnosis

Wind-lifted shingles, failed pipe boots, chimney flashing and ice dam damage. We find the actual entry point, which is rarely where the stain shows up inside.

Red cedar roofs

The traditional Cape roof, installed on breathable underlayment so the shingles dry from both sides. The right choice for many 6A antiques and shingle-style houses.

Standing seam metal roofs

Aluminum or coated steel panels with clips spaced for Cape wind, snow guards above entries and flashing details that keep salt air out of the seams.

Flat and rubber roofing

Low-slope porches, dormers and additions get a membrane roof, not shingles. We install modified bitumen and EPDM with proper drainage and edge metal.

Skylights, gutters and ventilation

A reroof is the time to replace a fogged skylight, add ridge and soffit ventilation that stops ice dams, and hang new aluminum gutters.

Built for the Cape

Two coasts, two kinds of damage. A Cape roof has to handle both.

The south side of the Cape faces Nantucket Sound and gets the wind. Southwest gales in summer, southeast in a nor'easter, and the gusts that peel the first course of shingles off a roof that was nailed to a national standard instead of a coastal one. We nail to the manufacturer's high-wind pattern on every roof, seal the starter course and use ring-shank fasteners where the deck needs them.

The north side faces Cape Cod Bay and gets the ice. Bay-side houses in Sandwich, Barnstable Village, Yarmouth Port, Dennis and Brewster see more snow and more freeze-thaw, and ice dams form wherever warm attic air meets a cold eave. Our fix is a full ice and water membrane at the eaves plus real ventilation, not a heat cable.

Underneath both is the deck. Twenty years of salt air finds the nails, and a roof that leaked for a season has usually rotted a patch of sheathing. We replace what we find during tear-off and tell you about it the same day, with photos, so there are no surprises on the final invoice. On Route 6A homes in the Old King's Highway district, a change in roof material or color is reviewed by the district committee, and we handle that filing.

Where we work

Roofing contractor in every Cape town.

Based in Osterville, on the roof in all fifteen towns. Here is what the location does to the job.

Upper Cape

Bourne, Sandwich, Falmouth and Mashpee. Falmouth and Bourne take Buzzards Bay weather head on. Sandwich splits between 6A antiques on the bay and newer neighborhoods inland.

Mid-Cape

Barnstable's seven villages, Yarmouth and Dennis. Most of our roofs are here. Hyannis, Centerville, Osterville and Cotuit on the Sound side; Barnstable Village, Yarmouth Port and Dennis Village on the bay.

Lower Cape

Harwich, Brewster, Chatham and Orleans. Chatham's exposure to the open Atlantic makes it the hardest roofing environment on the Cape. Brewster and Orleans carry the 6A review.

Outer Cape

Eastham, Wellfleet, Truro and Provincetown. Wind from both shores and a lot of cedar and low-slope roofs on cottages. We stage materials carefully because of Route 6 and the summer season.

Serving Cape Cod only. We do not roof on Nantucket, Martha's Vineyard or off-Cape. Shop and office: 14 Parker Rd, Osterville, MA 02655.

Questions we get on the first call

What Cape homeowners ask a roofer first.

How long does a roof replacement take on Cape Cod?+
Most residential roofs are done in one to three days once we start, depending on size, pitch and how much deck repair we find. We schedule around weather windows because a Cape roof cannot sit open overnight in nor'easter season.
What roofing holds up best in Cape Cod weather?+
Architectural asphalt shingles rated for high wind are the workhorse. Red cedar suits traditional houses and lasts well when installed on a breathable underlayment. Standing seam metal handles salt and wind extremely well if the clips and flashing are done right. Low-slope sections need a membrane, not shingles.
Do you repair roofs or only replace them?+
Both. Isolated wind damage, a failed flashing or an ice dam leak is usually a repair. Curling shingles, granules in the gutters and a roof past twenty years is usually a replacement. We inspect first and tell you honestly which it is.
How do I know if my roof needs replacing?+
Missing or curling shingles, dark streaks, granules collecting in gutters, daylight visible in the attic and leaks that come back after a repair. On the Cape, salt and wind shorten roof life compared to inland Massachusetts.
Do you handle ice dams?+
Yes. The fix is a full ice and water membrane at the eaves and valleys plus attic ventilation and air sealing so the roof deck stays cold. We also repair the damage ice dams leave behind.
Is roof work in the Old King's Highway district reviewed?+
Yes, when the material or color visible from Route 6A changes. Like-for-like asphalt is usually straightforward; a switch to metal or cedar needs the committee's approval. We prepare the filing.
Which towns do you roof in?+
All fifteen towns in Barnstable County: Bourne, Sandwich, Falmouth, Mashpee, Barnstable, Yarmouth, Dennis, Harwich, Brewster, Chatham, Orleans, Eastham, Wellfleet, Truro and Provincetown.

What helps on a first visit

Nothing is required, but any of these help:

  • A photo of the roof from the street
  • Any interior stains or leaks and when they appear
  • Roughly when the roof was last replaced
  • Whether the house is on or near Route 6A
