Master Seal Roofing

Master Seal Roofing, run by Angelo (and, in many reviews, his son Sam) out of Malden, built its name on the emergency call: a leak found on a rainy night, a hole chewed open by animals, water pouring through a bedroom ceiling. Reviewers describe response times measured in hours, not days — a 2026 review recounts a callback two hours after calling about a small roof leak, and a 2021 review describes a fix finished within 24 hours of a storm that opened up a second-floor ceiling. A recurring thread is a smaller bill than expected: several customers say other roofers quoted a full tear-off and replacement, and Angelo instead diagnosed — and charged for — a smaller flashing repair. In a 2024 review, a homeowner who'd been quoted a new roof elsewhere wrote that a month after Master Seal's smaller flashing fix, the leak hadn't returned. Some customers have stuck around for years: a 2024 review describes using the company 'more than a few times,' and another 2024 review recounts a relationship going back roughly 15 years, from a garage leak to an AC-unit seal to a full roof replacement. That said, the same span of reviews carries a real cluster of complaints, mostly on bigger or paid jobs. A 2023 review reports a $7,375 charge that didn't stop a leak despite several return visits. A 2022 review describes a five-year-warranty rubber-roof repair that leaked again, with calls and emails afterward going unanswered. Two more 2022 reviews describe serious delays: one reports three missed appointments and no callback afterward, another describes a job that stretched from a promised week to nearly two months, with the crew claiming it was finished several times before it actually was. A 2024 review adds that a request for a receipt with a license number went unanswered after the job was done. One 2023 reviewer pushed back directly on the no-show complaints, saying that wasn't their own experience. A 2021 review also reports the company advertising through unsolicited junk faxes. Worth calling for a fast read on a leak, especially if you suspect you're being oversold a full replacement — but on a bigger job, get the scope, price, and any warranty terms in writing before work starts, and make sure you get a receipt with a license number when it's done.
