Mastrangelo and Sons

Mastrangelo and Sons is a Belmont, MA roofing shop the company says goes back to 1984, when founder Tony Mastrangelo started what is now a second-generation family business he runs today with his two sons — its specialty on record is slate and copper restoration, plus tar-and-gravel, rubber roofing, and siding work. The written record here is thin and mixed. In a 2025 Google review, one customer's complaint wasn't about the roofing itself but about the crew parking in residential spots and refusing to move — a conduct issue rather than a craftsmanship one, though it's the only detailed account on file. Further back, a 2015 OSHA workplace-safety citation carried a $6,160 penalty, a matter of public record from over a decade ago with no indication it recurred. On the credentialing side, its Massachusetts home improvement contractor registration is active, and Google shows a 4-star average from its four ratings, even though only one specific review made it into the written record. Its BBB profile lists no accreditation and no rating issued. Worth asking about before booking: the 2025 parking complaint and general professionalism on site, given how little else is documented. For a homeowner in the Belmont/greater Boston area needing slate, copper, or standard roof work from a business with decades of family history, it's worth getting a couple of current references given how sparse the public track record is.
