MassTech Roofing & Building

MassTech Roofing & Building is a Pembroke company that reviewers keep calling on for the roofing problems other contractors couldn't solve — a leak that had stumped several previous roofers, a raccoon-damaged roof vent discovered by a neighbor while the homeowners were away, a chimney cap that blew over and got fixed the same day it was reported. Run by owner Costi Serban, who founded the company in 2009 according to the Better Business Bureau, MassTech describes itself as a roofing and home addition contractor serving Greater Boston and the South Shore. The consistent thread across dozens of Google reviews from 2021 through 2026 is responsiveness under pressure: customers describe getting a callback almost immediately, a next-day visit, and a fix delivered before a bigger problem set in. One reviewer's ceiling leak was located within ten minutes of the owner walking through the door after several other roofers had failed to find it. On calmer jobs, the same care shows up in the details — matching new shingles on a shed to a freshly replaced house roof, offering paint color guidance for cedar shingle work, and plowing a customer's driveway during a blizzard while finishing an unrelated addition. That addition — one bedroom and one and a half bathrooms, built fully handicap accessible with a ramp — points to a business that has grown past roofing alone; its own site lists home additions, skylights, metal roofing, and decking alongside roof work, and its newer Angi profile adds carpentry, framing, and siding. Sources don't agree on exactly how long the company has been around, though: the BBB puts it at 17 years since a 2009 start, the company's own site claims 30 years, and Angi lists 24 — worth asking about directly if company history matters to you. One reviewer reported a missed estimate appointment in 2024, with the contractor arriving 45 minutes late by the time they called to check in — an outlier against an otherwise strong, detailed response record, but real enough to mention. MassTech is a strong option for a roofing problem that's stumped someone else, for storm or animal damage that needs a fast fix, or for a South Shore homeowner planning a roof-plus-addition project who wants one crew handling both — just confirm current availability given how quickly this crew is often called in.
