New Roof Installation Across New York City

RoofingServiceNY.com installs new roofing systems on new construction, additions, extensions, and structures that need a roof system built from scratch — as opposed to tearing off and replacing an existing one. Every installation follows manufacturer specifications for underlayment, fastening patterns, and ventilation to keep warranties valid and performance guaranteed.

New Construction Roofing

For ground-up builds across Brooklyn, Queens, and the Bronx, we install complete roofing systems from decking inspection through final shingle or membrane layer, coordinated with your general contractor's timeline.

Additions & Extensions

Adding a dormer, rear extension, or second story? We tie new roof sections into your existing roofline with proper flashing transitions so the addition doesn't become a future leak point.

Underlayment & Ventilation Systems

A roof is only as good as what's underneath it. We install synthetic and felt underlayment rated for NYC's freeze-thaw winters, plus ridge and soffit ventilation systems that prevent attic moisture buildup and ice damming.

Manufacturer-Certified Installation

Our crews are certified installers for major shingle and membrane brands including GAF, CertainTeed, and Owens Corning, which qualifies your new roof for extended manufacturer warranty coverage beyond standard material-only terms.

Frequently Asked Questions

What's the difference between roof installation and roof replacement?

Installation typically means putting a roof on new construction, an addition, or a structure without an existing roof. Replacement means tearing off and replacing an existing roof.

How long does a new roof installation take in NYC?

A typical single-family home takes 1 to 3 days depending on size and material. Larger commercial installations can take one to two weeks.

Are you certified to install GAF, CertainTeed, or Owens Corning systems?

Yes, which allows us to offer extended manufacturer warranties beyond standard material coverage.

Do you handle permits for new roof installations?

Yes. We manage NYC Department of Buildings permit filings required for new installations and structural additions.
