OneGuard Roofing LLC

OneGuard Roofing LLC is a Lexington-based roofing and exterior-cleaning contractor serving Greater Boston — Lexington, Arlington, Cambridge, Somerville, Waltham, Wellesley, Medford and Lincoln. It holds an active Massachusetts home improvement contractor registration, and owner Elshan Mustafaev (known in reviews simply as El) also carries a Massachusetts Construction Supervisor license that Thumbtack lists as verified on its platform. The company has been in business 8 years, is Thumbtack's Top Pro for both 2024 and 2025, and runs a perfect 5.0 rating on both Google (33 ratings) and Thumbtack (162 ratings). On the roofing side, reviews describe everything from routine moss-and-algae cleanings to full tear-offs. In a 2025 review, one homeowner had a 1,700-square-foot roof reshingled in a single day, calling the assessment thorough and the crew's explanation of materials and layering detailed. In a February 2026 review, a leak traced to an ice dam got same-day attention, with the crew working into the evening to stop it and returning the next day to handle other trouble spots. Storm damage shows up too — a 2025 review describes aluminum roof trim torn off in high winds getting repaired within 24 hours of the call. Gutter work and exterior pressure washing come up just as often, and just as positively. Reviewers describe gutter cleanings, gutter guard installs, and repairs done same-day with before-and-after photos sent afterward; several say they called OneGuard back for a second or third job after being impressed the first time. On the pressure-washing side, jobs range from siding, patios and decks to driveway snow removal, with reviewers consistently noting fair, unchanged pricing and thorough cleanup. El comes up by name in nearly every review — for showing up personally, explaining the work before starting, and following up afterward — and a striking share of reviewers say this is their second or third time hiring the company. For roofing, gutters, or exterior cleaning specifically, this is a well-documented, consistently praised local operation.
