Commercial Roofing Services Across Long Island, NY
Built Right Commercial Roofing Inc. has been serving Long Island businesses for over 25 years, providing expert commercial roofing services throughout Nassau and Suffolk Counties. From the dense suburban commercial corridors of Nassau County to the expansive industrial parks of the Route 110 and Hauppauge corridors in Suffolk, our crews understand the building types, local permitting requirements, and weather challenges unique to Long Island. We are fully licensed and insured across both counties.
Long Island's Coastal Climate Challenge
Long Island's geography creates roofing conditions unlike anywhere else in the New York metro area. The island is bounded by the Atlantic Ocean to the south and Long Island Sound to the north, meaning commercial roofs face a combination of salt air corrosion, coastal storm exposure, and the same freeze-thaw cycling that affects all northeastern markets. Salt air is particularly damaging to metal flashings, fasteners, and unprotected membrane edges — components that can fail years earlier on Long Island than in an inland market. Nor'easters track directly across the island from the northeast, bringing wind uplift pressures that test membrane adhesion and seam integrity.
We specify and install roofing systems built for coastal performance. TPO with heat-welded seams is our most frequently recommended single-ply system for Long Island flat roofs, providing a monolithic watertight surface that resists wind uplift and coastal moisture. EPDM is an excellent choice for industrial and warehouse facilities, particularly in the inland areas of central Suffolk. Modified Bitumen remains a proven option for Nassau County's older commercial building stock. For all coastal-zone properties, we pay close attention to flashing material selection and termination details.
Long Island Service Areas
Nassau County
Nassau County's commercial roofing market spans strip retail centers, medical offices, multi-tenant commercial buildings, and industrial properties throughout communities including Hempstead, Garden City, Mineola, Hicksville, Massapequa, and Freeport. Much of Nassau's commercial building stock dates from the mid-20th century and carries aging Modified Bitumen or built-up roofing systems that need professional assessment before any new membrane is applied. We provide free core sampling and infrared moisture scanning to identify wet insulation and determine whether overlay or full tear-off is the right approach.
Suffolk County — Western
Western Suffolk County — including Farmingdale, Melville, Huntington, and the Route 110 corridor — is one of the most active commercial and light-industrial roofing markets in the region. The Route 110 corridor from Farmingdale to Melville is home to major corporate campuses, office parks, and distribution facilities with large flat-roof footprints. We handle re-roofing and preventive maintenance for commercial properties of all sizes throughout this high-density business district.
Suffolk County — Central & Eastern
The Hauppauge Industrial Park — one of the largest industrial parks in the Northeast — along with the Ronkonkoma, Islandia, Bohemia, and Bay Shore commercial corridors makes up a large portion of our Suffolk County work. Industrial and warehouse facilities in these areas typically have large EPDM or Modified Bitumen systems that benefit from systematic maintenance programs to maximize service life. We offer multi-property maintenance contracts for commercial real estate portfolios in central and eastern Suffolk.
South Shore & North Shore
Long Island's south shore communities — from Long Beach and Oceanside through Bay Shore and Babylon — face the most direct Atlantic storm exposure and require particular attention to wind-rated installations and flashing integrity. The north shore communities along the Sound have slightly more sheltered exposure but still benefit from coastal-grade material specifications. We provide free assessments throughout both coasts of Long Island.

Frequently Asked Questions — Commercial Roofing on Long Island
We offer emergency roof repairs, roof coating, TPO, EPDM, and Modified Bitumen installations, routine maintenance programs, and complete roof replacements for commercial buildings across Nassau and Suffolk Counties. We handle all Nassau County and Suffolk County building department permit applications for qualifying work.
Long Island's proximity to the Atlantic Ocean and Long Island Sound means commercial roofs face salt air corrosion that accelerates metal flashing degradation, fastener rust, and membrane seam failures. Coastal storm exposure — including nor'easters and hurricane-track storms — adds wind uplift stress. We specify and install materials rated for coastal environments and pay close attention to flashing details and seam integrity on every Long Island project.
Twice yearly is our recommendation for most Long Island commercial properties — once in spring after winter storm season and once in fall before it begins. Coastal properties and older buildings should be inspected more frequently. After any significant storm event, a post-storm inspection is strongly advised to catch wind damage or lifted seams before they become interior leaks.
For most Long Island flat-roof commercial applications we recommend TPO for its energy efficiency and heat-welded seams. In coastal areas with significant salt air exposure, we give careful attention to membrane quality and flashing materials. EPDM is an excellent long-term option for industrial buildings in the Hauppauge and Ronkonkoma areas. Modified Bitumen remains a reliable choice for older building inventory throughout Nassau County.

Yes. We serve commercial properties throughout Long Island including Nassau County communities like Hempstead, Garden City, Mineola, Hicksville, and Massapequa, as well as Suffolk County including Hauppauge, Ronkonkoma, Melville, Farmingdale, Islandia, Bay Shore, and beyond.
