Boston Alliance Roofing

Boston Alliance Roofing is a Norwell, family-owned commercial roofing company that says it's now in its third generation, with owner Dorothy Stevens on-site for every job. Its stated specialty is flat and commercial roofing — EPDM, hot tar, white TPO, torch-down, metal, and silicone coating — plus roof repair and snow removal across Massachusetts and Rhode Island; it also does driveway sealcoating and crack repair under a "Boston Alliance Roofing and Seal Coating" line. The written record splits fairly sharply along those two lines of work. Roofing reviews describe quick, reasonably priced jobs — a flat commercial roof replacement called quick and efficient, several residential roofs finished fast at a fair price. The driveway sealcoating side draws more complaints: one homeowner called the paving work "not their specialty," saying it was done so poorly it was hard to tell what had actually been completed; another described a second coat of sealer with no overlap and visible brush strokes; a third recounted repeated rescheduling, a mid-job price increase, a messy asphalt repair that had to be redone, and a promised $200 refund that never arrived. A separate reviewer objected to a marketing fax. Google shows a 3.3-star average from 7 ratings, notably lower than the 4.6 stars Angi shows across 18 — worth weighing both. Angi lists a Massachusetts trade license number for the company, though it hasn't been independently verified against the state registry. For flat or commercial roofing, the reviews lean positive and specific; for driveway sealcoating, the record is decidedly mixed — get the scope, price, and timeline in writing before that kind of job.
