Yes. Flat roof replacement is one of our most common Boston services. We install EPDM rubber, TPO single-ply membrane, and modified bitumen systems on triple-decker roof decks throughout Dorchester, Roxbury, and South Boston. Flat roof replacement on a standard triple-decker typically costs between $4,000 and $9,000 depending on deck condition, drain configuration, and membrane type.
