Hollstein Roofing, Inc.

Hollstein Roofing is a South Shore roofing contractor based in Hanover, Massachusetts, run by President David Hollstein and describing itself as commercial, industrial and residential — offering roof replacement, repair and ongoing maintenance across towns from Boston to Marshfield. Its Massachusetts home improvement contractor license is active, and the company has been BBB-accredited with an A+ rating since 2016. What the public permit record actually shows, though, skews heavily commercial: of 59 permitted projects on file, the bulk are large flat-roof jobs — a $330,000 EPDM roof in Roxbury, a $1.285 million commercial job in Braintree, a $125,000 project in Norwell — with only one small residential asphalt-shingle job turning up in the record. A Reddit commenter in early 2026 named Hollstein as a company that handles both commercial and residential roofing out of Hanover. A couple of details don't line up perfectly across sources: the company's own website lists a Holbrook address rather than the Hanover address its BBB and directory listings carry, and its site states its tenure inconsistently — "over 40 years" in one spot and "over 39 years" in another — while BBB dates the business to 1980, putting it at 46 years. Given the license is active and the commercial track record is substantial, this looks like a solid pick for larger roofing jobs; a homeowner with a typical residential project should confirm directly that residential-scale work is a current priority and get a specific timeline before booking.
