EPDM Roofs


EPDM is a very durable synthetic rubber roofing membrane which is widely used in “low-slope” buildings around the world. The two main ingredients, ethylene and propylene, come from oil and natural gas. EPDM is a very popular roofing choice and we are the roofing service in Long Island for the job. We’ve been installing and repairing EPDM roofs for as many years and we can count, delivering top quality work for commercial and government buildings throughout the area.

EPDM provides durability against the elements. Hard rain and intense heat don’t damage this type of roof as much as many other options out there. Make sure you choose a roofing service in Long Island who can educate you and install your EPDM roof efficiently.

Modified Rubber Torch Roof Systems


Also known as modified bitumen, a single-ply rolled roof similar to ice-and-water shield, but impregnated with a mineral-based wear surface. The most cost effective and common of all of the roofing systems, modified torch offers a less expensive and quick fix to any roofing system. This torch-down system involves heating the adhesive as the material is unrolled across the surface of your roof. This method is a very common and efficient method for new roof or roof restoration in Long Island, New York.

Hot Tar


Hot tar is a petroleum based tar that we apply over almost anything except TPO, EPDM, or metal. Hot tar systems are mainly used for the flat roof of a commercial or industrial building. This system is a more affordable roof system and a great alternative to renewing your roof. This roof system will give your existing roof an additional 8 to 10 years without the hassle of maintenance. All hot tar systems will be coated what an aluminum coating to reduce temperature of your roof as well.
