Winthrop’s peninsula geography exposes every property to direct Atlantic conditions that standard inland roofing specifications don’t address. Master Roofers uses stainless steel ring-shank fasteners (not standard galvanized) to prevent corrosion in salt air, marine-grade aluminum drip edge, and only 130 mph-rated shingles on all Winthrop installations. Our post-storm inspection guarantee — free inspection within 72 hours of any named storm — gives Winthrop homeowners year-round peace of mind.
