MassTech Roofing & Building

MassTech Roofing & Building is a Pembroke-based roofing and home-addition contractor that says it serves Greater Boston and the South Shore, including Marshfield, Plymouth and Truro. BBB's profile puts the company in business since 2009, 17 years, under owner Costi Serban — the company's own website instead claims over 30 years in business, and Angi lists 24 years of experience; the three sources don't agree on how long it's actually been operating. What repeats across 25 Google reviews from 2021 through mid-2026 is speed on emergencies and a hands-on owner. A chimney cap that blew off got a same-day fix, a raccoon-damaged roof vent was repaired the next day, and in a 2023 review one homeowner described Costi finding a ceiling leak within minutes after several other roofers couldn't locate it. Full roof replacements come up again and again, including matching details like reshingling a shed to match the house and cedar shingle and skylight work. The company has also taken on larger projects — one reviewer describes a bedroom and accessible bathroom addition with a ramp. Google shows a 4.9-star average across 65 ratings, and BBB lists the business as accredited with an A+ grade. It isn't spotless. One customer says the estimator never showed for a scheduled appointment, arrived 45 minutes late to the rescheduled one, and then left items off the written estimate. Another, in a 2021 review, described a job that started well and "ended in a fizzle," without saying what went wrong. MassTech looks like the call for roof replacement and repair, especially anything urgent. Given the one no-show complaint, it's worth confirming an estimate appointment a day ahead and getting the full scope of work in writing before signing off.
