Commercial Roofing Contractor in Suffolk County

From our shop in Sayville we cover all of Suffolk County — Islip, Brookhaven, Smithtown, Huntington, Babylon and out east through Riverhead. Suffolk buildings take a beating that inland roofs do not: salt air off the Great South Bay and the Sound, hard winter freeze-thaw cycles, and summer heat that cooks an unprotected membrane. That is why we install systems built for it, including TPO and EPDM rubber, modified bitumen, torch-applied systems, hot tar built-up roofing and energy-saving reflective coatings, using GAF Commercial Systems, Firestone and Johns Manville products. Whether you need a full tear-off and new roof, a re-roof over a sound deck, or a coating that buys you several more years, we walk the roof first, show you photos, and give you a free written estimate. Warranty options run up to 20 years.

  • What kind of commercial roof is best for a building in Suffolk County?

    For most flat and low-slope buildings here we recommend TPO or EPDM. TPO reflects heat and lowers cooling costs, EPDM handles temperature swings well and is easy to repair. We look at your deck, drainage and budget before recommending one.

  • Can you re-roof without shutting my business down?

    Yes. Most commercial jobs are done with the building fully in operation. We stage materials to keep entrances and parking clear and can work nights or weekends when the work is over an occupied space.

  • Are you licensed, insured and do you offer a warranty?

    We are licensed and insured, we are members of the National Roofing Contractors Association, and we offer warranty options up to 20 years on new commercial roof installations.
