Doherty Slate Roofing

Doherty Slate Roofing works almost exclusively in slate and copper out of Somerville, MA — the kind of century-old roofing most general roofing companies don't staff for. The company says it's owner-operated by Jason Doherty and lists 26 years in business on its BBB profile, with a self-reported service area covering Boston, Newton, and Wellesley alongside Somerville. The two most recent reviews, both from June, describe exactly what shows up across the wider history: a team that stayed in touch for weeks after a job to make sure an initial slate and roof problem actually stayed fixed, and, on a separate job, one that replaced missing slates at a reasonable price, flagged future problems before they became leaks, and cleaned up work a previous roofer had left in bad shape. Reviews going back to 2022, plus a scattering of third-party mentions dating even further, describe the same throughline: careful, detailed slate and copper craftsmanship on the kind of old roofs many roofers won't take on. The paperwork backs it up. Its Massachusetts Home Improvement Contractor license is verified active, its BBB profile carries an A+ grade with accreditation dating to December 2023, and it's a listed member of the Somerville Chamber of Commerce. On Google it holds 4.9 stars across 57 ratings, consistent with a broader run of 37 reviews logged from 2022 through 2026 across six different sources. Its site also lists copper gutter installation and drone roof inspections alongside the core slate work, so there's more on offer than repairs if a full copper system or an inspection-first look at an old roof is what's needed. One thing worth confirming directly: only two reviews have landed in the past six months, a real slowdown from its longer pace, so it's worth asking about current scheduling before counting on a fast start. For a slate or copper roof — repair, restoration, or a careful new installation — Doherty has the active license, the A+ BBB standing, and years of consistent praise for the actual craftsmanship. The one thing to pin down before booking is how soon they can get to the job.
