Full tearoff, deck inspection, and ice protection for Somerville’s triple-deckers, Victorians, and multi-family homes — pitched and flat roof sections handled on the same project, in the tightest lot conditions in Greater Boston. Google Guaranteed. 150+ five-star reviews.
Somerville’s roofs have been layered, patched, and reroofed for over a century. About 60% of the city’s housing was built before 1940, and the triple-deckers that define most neighborhoods have both pitched and flat sections — two entirely different roof systems on the same building. Replacing a roof here means understanding both.

Whether it’s a single-family Victorian near Prospect Hill or a triple-decker on Winter Hill, every replacement includes the full system.
Most single-family replacements fall between $14,000 and $30,000. Triple-deckers run higher — multiple roof sections, flat-to-pitched transitions, and multi-story access add complexity and labor. Deck condition drives cost too, and Somerville’s oldest homes almost always need sheathing replaced once we strip the old roof. We provide a detailed written estimate after inspecting the roof in person.
Yes — it’s the bulk of our Somerville work. Triple-deckers typically have a pitched front section and a flat rear section, sometimes with additional flat sections over porches or additions. We handle both systems on the same project, including the critical transition where pitched meets flat, plus tenant coordination and phased scheduling when needed.
Ice & water shield at every eave, valley, rake, and penetration — well beyond the code minimum. We also upgrade ventilation with ridge vents, soffit intake, and baffles. On Somerville’s triple-deckers, heat rising from the lower two units supercharges attic temperatures and makes ice dams worse than on single-family homes. A replacement is the best opportunity to fix both the symptoms and the root cause.
Most single-family homes take 1–2 days. Triple-deckers take 2–4 days depending on roof sections and deck condition. Somerville’s tight lot spacing can add staging time at the start of the project, but we build that into the schedule upfront so there are no surprises.
CertainTeed Landmark and Landmark Pro architectural shingles. We hold CertainTeed’s Master Craftsman certification — their highest contractor level — which means every roof is installed to manufacturer spec. That’s what qualifies for the strongest available warranties.
We photograph it, show you, and replace it before the new roof goes on. Common findings on Somerville homes include soft sheathing around chimneys that have been reflashed half a dozen times, rotted boards at eave lines from decades of ice dam water backup, and moisture damage where bathroom fans vent into the attic instead of outside. Sheathing replacement is priced per sheet and only done when needed.
