Commercial Roofing Contractor on Long Island
Long Island's commercial buildings face unique roofing challenges — flat or low-slope roof designs that must handle ponding water, UV exposure, thermal cycling, and the heavy weather events that hit Nassau and Suffolk County every year. When your commercial roof fails, it affects your business operations, your inventory, your equipment, and your tenants.
ERS Roofing & Siding provides professional commercial roofing services for businesses across Long Island. From small retail storefronts to large industrial buildings, we install, repair, and maintain flat roof systems built to perform in Long Island's demanding climate.
Commercial Roof Systems We Install
TPO Roofing (Thermoplastic Polyolefin)
TPO is the fastest-growing commercial roofing material in the industry and our most-requested system for Long Island businesses. TPO membranes are heat-welded at the seams — creating a bond stronger than the membrane itself — and the white reflective surface significantly reduces cooling costs in summer. TPO resists UV damage, chemical exposure, and punctures, making it ideal for Long Island's mixed commercial environments.
EPDM Rubber Roofing
EPDM (ethylene propylene diene monomer) is a proven rubber roofing membrane that's been used on commercial buildings for over 50 years. It's extremely durable, handles temperature extremes well, and is one of the most cost-effective flat roof solutions available. EPDM is available in black (standard) and white (reflective) versions and works well on Long Island buildings of all sizes.
Modified Bitumen
Modified bitumen is a multi-layer asphalt-based roofing system that offers excellent waterproofing and durability. It's particularly well-suited for Long Island's climate because of its flexibility in cold weather and resistance to thermal cycling. We install both torch-applied and self-adhered modified bitumen systems depending on the building requirements.
Built-Up Roofing (BUR)
Built-up roofing — the traditional "tar and gravel" roof — uses alternating layers of asphalt and reinforcing fabric topped with a gravel ballast. BUR systems are extremely durable and provide excellent waterproofing for large commercial buildings. While newer single-ply systems have gained market share, BUR remains a reliable choice for Long Island commercial properties.

What Our Customers Say
“ERS installed a TPO system on our 8,000 sq ft commercial building and the work was excellent. They worked around our business hours, cleaned up every day, and the price was competitive. Our energy bills dropped noticeably after the white TPO went on.”
Mike R., Property Manager
Deer Park, NY
“Our flat roof had been patched multiple times by other companies. ERS came in, did a full tear-off, repaired the decking, and installed modified bitumen. No more leaks. They were upfront about the cost and timeline from day one.”
Steve & Sons Auto
Babylon, NY
“Needed the roof on our medical office repaired urgently after storm damage. ERS responded quickly, tarped the damaged area the same day, and completed the permanent repair within a week. Very professional.”
