GN Exteriors - Roofers in Braintree

GN Exteriors is a Braintree roofing and siding contractor that says it was founded in 2002 by master roofer Guillermo Naranjo and is family owned, and reviewers keep naming Manny, the owner. Its Google listings carry 5 stars from 118 and 86 ratings. Quick storm calls are a big part of it. A March 2026 customer called in the morning and had the roof fixed the same day, another that month needed repairs after a nor'easter, and a December 2025 reviewer with wind damage and a broken gutter had an assessment the next day. Larger jobs show up too: in May 2026 a condominium association described a siding project on a seven-unit beach house, a June 2026 customer described work on a three-story Victorian with seven condominiums by the Atlantic, a June 2025 reviewer had an 11-unit Jamaica Plain condo roof replaced, and a February 2026 customer had roof, siding and gutters done together. In an October 2021 review, a customer described vinyl siding replaced with Hardie Plank and a two-hour visit from James Hardie representatives checking the installation.
