Garpelli Home Improvement

Garpelli Home Improvement is a Marlborough, Massachusetts roofing company built around one name that keeps showing up in its reviews: Guilherme "G" Garpelli, the owner who founded the business after a stretch managing crews at one of the country's largest roofing companies. Its own site describes him as a Brazilian immigrant who arrived with roofing and project-management experience and built the company from there. The state's home improvement contractor registration for the company is active, and alongside its core roofing work it also does siding, gutter, and attic-fan jobs. The volume here is the story: 34 five-star ratings on Google and another 14 on Thumbtack, with reviews stretching from 2023 through mid-2026 telling a very consistent version of the same job — a same-day or next-day quote, a crew that shows up on time, and a roof finished in a single day. In a 2025 review, a customer described the crew stripping and re-roofing an entire house the day after Christmas, all in one day; another, from 2025, described two sheds re-roofed in four hours. Several reviewers who first hired Garpelli for roofing came back for siding, gutters, or an attic fan, and one 2024 review described the crew coming out right away to repair storm damage a tree had caused to a roof it had installed three years earlier. The one lower mark on file, a 2024 four-star review of a barn roof, still described the job as finished on time and looking good. Worth asking about directly: a federal OSHA inspection opened in November 2024 at a Garpelli Home Improvement facility in Belchertown resulted in two citations and roughly $9,930 in proposed penalties — a real regulatory mark that the review volume alone doesn't capture. It's also worth noting that the Better Business Bureau files the company under a different name, Garpelli & Pena Home Improvement Inc., than the one on its license and website; likely the same operation, but worth confirming. For a straightforward roof replacement or repair where speed and a hands-on owner matter, this is a company with years of consistent, specific praise behind it — just raise the OSHA history and get the current entity name straight before signing anything.
