Roofing Contractor in Dorchester, MA

Dorchester is triple-decker country. A City of Boston study found triple-deckers made up about 35% of Dorchester’s housing stock — the largest number in the city — and those buildings typically carry flat roofs, which is a completely different job from a suburban shingle roof.

Roofs in Dorchester

Flat and low-slope, not shingles

Boston built an estimated 15,000 three-deckers between 1880 and 1930, with Dorchester accounting for roughly a third of them. They are defined by wooden walls and flat roofs — which means membrane work, not asphalt shingles.

  • ✓ Flat and low-slope roofs needing membrane rather than shingle systems
  • ✓ Three storeys of occupied units under one roof, so a leak affects everyone
  • ✓ Parapet walls and their flashing as a common failure point
  • ✓ Internal drains and scuppers that block and pond water
  • ✓ Mansard roofs around Clam Point and Harrison Square on Italianate houses

What we see on Dorchester roofs

A flat roof fails differently
from a pitched one

A pitched roof leaks where water runs. A flat roof leaks where water sits. On a three-decker that difference matters, because ponding water finds the weakest seam and then travels through three floors of housing before anyone sees a stain.

  • ✓ Ponding water where the roof has lost its fall to the drains
  • ✓ Failed seams and laps in older membrane
  • ✓ Parapet and wall flashing that has pulled away
  • ✓ Blocked internal drains and scuppers backing water up
  • ✓ Mansard sections needing different detailing from the flat field
  • ✓ Named neighbourhoods across the area — Savin Hill, Ashmont Hill, Uphams Corner, Fields Corner, Codman Square, Lower Mills and Jones Hill

Permits in Dorchester

Dorchester is Boston,
so permits go through the city

Dorchester was its own town from 1630 until it was annexed to Boston in 1870, so there is no Dorchester building department. Permits run through the City of Boston Inspectional Services Department, which manages the building permit process for the whole city. We establish which permit type your job needs and pull it. We hold Construction Supervisor License CS-118483 and HIC registration #204689.

Dorchester roofing questions

What Dorchester homeowners ask us

Do you do flat roofs?
Yes. In Dorchester that is most of the work — triple-deckers carry flat roofs, which need a membrane system rather than shingles.
Who issues my permit in Dorchester?
The City of Boston Inspectional Services Department. Dorchester has been part of Boston since 1870, so there is no separate town department.
My third-floor ceiling is staining. Is it the roof?
Usually, on a flat roof — but not always directly above the stain. Water on a flat roof travels along the deck before it finds a way through, so we trace it rather than guess.
How long does a flat roof last?
It depends on the system and how well the drainage works. Standing water is what kills flat roofs, so drains and fall matter as much as the membrane itself.
I have a mansard. Is that different again?
Yes. A mansard combines a near-vertical pitched face with a flat or low-slope top, and the two need different treatment plus a proper transition between them. Clam Point and Harrison Square have a lot of them.
Do you work on multi-family buildings?
Yes, residential and commercial both. See our roofing services page.
