Roofing Service
Licensed Roofing Service Serving All Four Boroughs
Roofs in New York City take a beating that most of the country never sees: freeze-thaw cycles, ponding water on low-slope decks, coastal wind uplift, rooftop mechanical traffic and a hundred years of patch-on-patch history. Alliance General Contracting NY Inc is a licensed roofing contractor working across the Bronx, Brooklyn, Queens and Manhattan on flat and pitched roofs alike, from a single blistered seam on a Westchester Avenue two-family to a full modified-bitumen replacement on a multifamily building.
Most of the roof failures we are called for are not mysterious. They start at flashing, at parapet walls, at skylight curbs, at drains that were never re-pitched, and at seams that were cold-lapped on a day that was too cold. Because we inspect before we quote, you get told what actually failed not a reflex recommendation to replace everything.
Every roofing service project starts with a free on-site estimate and a written scope. We are based at 2362 Westchester Ave, Bronx, NY 10462 close enough to the whole Bronx to respond quickly, and working daily in Brooklyn, Queens and Manhattan. Call 718-737-2143 or email info@alliancegeneralcontractingny.com to get on the schedule.
