Your Local Roofing Contractor in Dorchester
Dorchester projects usually start with a diagnosis rather than a price. A ceiling stain in a three-decker rarely comes from the spot directly above it — water tracks along rafters from a failed chimney flashing, a split rubber seam or a gutter that has been overflowing behind the fascia for years. We trace it to the source so you are not paying twice for the same leak.
We also plan Dorchester jobs around the people living in them. Multi-family buildings mean tenants, shared driveways and parked cars, so we sequence tear-off and dry-in the same day, keep debris chuted into a covered container, and give occupants notice before noisy phases. The building stays livable while the work gets done.
