Historical Slate Roofing Co

Thirteen years on Somerville roofs, and essentially one specialty: slate. Historical Slate Roofing Co. is a two-person partnership at 85 Gordon Street run by Kevin M Williams II, trading since October 2012 and accredited by the Better Business Bureau since 2014 at an A+ grade. The service list is narrow by design — slate and copper roofing installation and maintenance, copper flashing, chimney and roof leak repair, downspouts and gutters. What stands in for a review history here is pictures and permits: 15 photos published on the BBB page and 17 permitted projects logged on BuildZoom. BuildZoom also lists a Massachusetts home improvement contractor registration, number 180226, and says it checked it as active in March 2026 — that is the directory's check rather than the state's, so ask for the number and confirm it at the Office of Consumer Affairs yourself. Slate is the trade where the wrong crew does expensive, visible damage, and a shop that does almost nothing else is a sensible place to start. Before committing, ask for two or three addresses you can drive past — slate work declares itself from the street — and settle the registration question first.
