Flat Roof Installation & Maintenance in NYC

About Flat Roof Services

Flat roofs are the defining feature of New York City's roofscape. From brownstone rooftops in Brooklyn to commercial buildings in Manhattan to row houses in Queens, the vast majority of NYC properties have flat or low-slope roofs. These roofs require specialized materials and installation techniques that differ entirely from pitched roof systems. HandyMen NYC specializes in flat roof services using all major systems—modified bitumen (torch-down and peel-and-stick), TPO (thermoplastic polyolefin), EPDM (rubber membrane), built-up roofing (BUR), and fluid-applied coatings. Each system has advantages depending on the building type, budget, and intended use of the roof. Our licensed roofers assess your specific situation and recommend the best system for your property. We handle complete flat roof replacement, section repairs, seam and flashing restoration, and preventive maintenance that extends roof life. Proper drainage is critical for flat roofs, and we ensure all installations have adequate slope to drains or scuppers to prevent ponding water, the leading cause of premature flat roof failure.

Common Issues

  • Ponding water that does not drain within 48 hours
  • Membrane blisters, cracks, or open seams
  • Flashing pulling away from parapet walls
  • Previous patches failing and leaking again
  • Roof reaching end of expected lifespan
  • Want to create usable rooftop space (deck, green roof)

When to Call a Professional

Flat roof work always requires professional expertise. The materials, tools, and techniques—including torch application for modified bitumen and heat welding for TPO—are specialized and potentially dangerous for untrained individuals. If your flat roof is ponding water, showing visible wear, has open seams, or is over 15-20 years old, have it professionally inspected. Flat roofs are also popular locations for rooftop decks and green roofs in NYC, and any addition to the roof must be properly engineered and permitted.

Customer Reviews

"After Sandy we swore we'd get the roof done right. HandyMen replaced our entire flat roof with a proper membrane system and it's been bone dry through three nor'easters."

Robert H. Tottenville, Staten Island

"HandyMen installed a new roof on our attached row house without disturbing the neighbor's side. Neat, professional work. No leaks after a full winter of snow and ice."
