Gilbert & Becker Co Inc

Gilbert & Becker has been roofing in Dorchester since 1947, when Harris Gilbert and Maurice Becker founded it; the company says it's stayed family-run since, with Gilbert's daughter Priscilla Alpert and her husband Howard joining in the late 1960s, and their son Alex joining in 1989. It's a union shop built around slate, copper, and historical-restoration roofing, plus custom sheet metal fabrication — work reflected in a long list of trade affiliations, including the National Roofing Contractors Association, the Slate Roofing Contractors Association, and a charter membership in the National Slate Association. Google shows 4.5★ across 14 ratings, though there are only three written reviews to go on. In a 2025 review, a customer said the company custom-fabricated a copper box gutter within days at a fair price, and described the office staff as courteous and helpful. In a 2023 review, another customer said they were able to find slate to match their existing roof quickly. For slate, copper, or historic-roof restoration work in the Boston area — the kind of specialty roofing not every contractor stocks or fabricates in-house — the company's decades of trade-association standing and hands-on custom metalwork are the strongest signal, even with a small public review count so far.
