Cambridge's housing stock is dominated by three-deckers and older single-families around Cambridgeport, Porter, Harvard, and North Cambridge — most with low-slope rear sections that need EPDM rubber, not shingles. That's why the majority of our Cambridge work is rubber roof replacement, tapered insulation, and hand-formed metal at parapets and scuppers, alongside architectural asphalt on pitched fronts. We're a 6-mile, one-business-day response from our Sibley Rd. shop in Waltham.
