Sentry Roofing

Sentry Roofing & Solar is a family-owned company that says it's worked New Hampshire and northern Massachusetts since 2004, based in Manchester and doing residential and commercial roof replacement, repair, metal and asphalt roofing, gutters, skylights, and solar installation. The volume here is large — 134 reviews across five platforms, and the last six months alone have brought 16, every one of them five stars. What repeats across the record is the sales and project-manager staff by name — Dave, Dillon, TJ, Drew — and speed: a 2026 review describes the crew dropping everything to stop an active leak within 30 minutes in freezing weather; another describes six workers arriving at 8am and finishing a full tear-off and reshingle by 6pm the same day. Two separate reviewers, both self-identified contractors, say they use Sentry for every roof on their own jobs. On Reddit, a 2023 post specifically praised Sentry's honesty over a competitor: told that sections of an older roof didn't need replacing yet and given advice on how to make them last a couple more years rather than being sold a full job. Its solar arm draws similar praise — a 2023 Reddit thread describes Sentry's mounting design and reading of the regulations getting a customer's array closer to a 120% return than a competitor's design. The record isn't spotless. A 2023 Reddit post described a four-day wait and a $600 charge for an emergency tarp patch, then difficulty getting a follow-up repair estimate with unanswered voicemails. A February 2026 review from an owner of a rental property described recurring, unresolved leak problems at the same condo across multiple winters despite repeated callbacks. And a 2022 review described being billed for four more sheets of plywood than were actually used on a porch roof. These are a minority against the volume of five-star accounts, and none of them appear in the past six months, but they're real and worth knowing. BBB lists a Massachusetts home improvement contractor license number and a construction supervisor license for the business, though those weren't independently verified against the state registry. New Hampshire has no statewide contractor registration to check. For roofing or solar work across New Hampshire and northern Massachusetts, the current run of reviews is strong and consistent — worth double-checking any invoice against the materials actually delivered and installed, given the one billing account.
