Garpelli Home Improvement

Garpelli Home Improvement is a Marlborough roofing company built around one man. The company's site says founder Guilherme Garpelli is a Brazilian immigrant who came to the U.S. with roofing experience and a project-management background, took a managerial role at one of the country's largest roofing companies within two years, and then started his own firm. Customers almost universally just call him "G", and the company's Massachusetts home improvement contractor registration is active. What reviewers keep returning to is speed. A December 2024 customer said the roof was finished in one day around the holidays; a June 2024 customer described a very large roof done in a single day and then hired the crew for windows and siding; and a May 2025 Thumbtack reviewer said the crew stripped the roof, repaired rot and re-roofed the whole house the day after Christmas, at "a fraction of the price of other roofing companies." A December 2025 customer said the price came in lower than anyone else's, the repair happened within a few days, and the crew worked around their granddaughter's nap. Cleanup is the other constant. A September 2024 customer said the crew was done by 3:00 and you could not even tell they had been there; a December 2024 reviewer called the cleanup spotless; a May 2025 Thumbtack reviewer said the site was left immaculate. Repeat business shows up too — an August 2025 customer whose roof Garpelli did three years earlier said the company came out right away to fix damage from a tree. The work is not only roofs: reviewers in 2024 and 2025 describe siding and gutter jobs, an attic fan replacement, a barn roof, and two large sheds finished in four hours. The thing to raise before signing is site safety. SVEP Navigator, which republishes U.S. Department of Labor enforcement records, reports an OSHA inspection of a Garpelli Home Improvement Inc roofing site at 55 Maple Street in Belchertown — not the Marlborough address the company works from — opened in November 2024 and resulting in two citations with $9,930 in proposed penalties. Ask directly how fall protection is handled on your job, and who will actually be on the roof: the BBB, which grades the company A+ without accrediting it, files it as Garpelli & Pena Home Improvement Inc. with one employee, while reviewers describe a crew. For a straightforward roof replacement where speed and price matter most, the written history here is unusually consistent. Get the crew, the safety plan and the warranty in writing before work starts.
