# Gilbert & Becker Co Inc

**Trade:** Roofing · **Address:** 24 Clapp St, Dorchester, MA 02125, USA · **Phone:** (617) 265-4342 · **Website:** https://www.gilbertandbecker.com/ · **Languages:** English

**Rating: 3.4/5** (low confidence) — from 3 reviews across 4 sources. A 0–5 star rating built from what customers and the public say (every review and mention weighted by where it was posted, how old, how detailed and how credible it is, shrunk toward a 3.5★ baseline when evidence is thin) plus what the record shows (Reddit recommendations or warnings, a registry-verified licence, how recently they were reviewed, customer work photos, BBB grade, negative news, a revoked licence). Positive record counts only as far as the reviews have earned it; penalties count in full. Confidence describes how much weighted evidence stands behind the number, never the number itself: low when fewer than about five normal reviews' worth of weight (or mentions only) support it, medium up to about twenty, high beyond that across at least two sources. An operator flag for a suspicious review pattern caps a rating at 3.5★ and marks it low.

## The honest read

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.

**Strengths:**
- Slate and copper specialists — union shop restoring historic roofs since 1947
- Custom metal fabrication — built a copper box gutter within days
- Trade-association standing — NRCA and Slate Roofing Contractors Association member
