Commercial Roof Repair & Restoration on Long Island, NY
Built Right Commercial Roofing Inc. provides comprehensive roof repair and restoration services for commercial and industrial properties throughout Long Island. With a large percentage of Nassau and Suffolk County's commercial building stock dating from the mid-20th century, many Long Island roofs are candidates for targeted repair or full-system restoration — a cost-effective alternative to complete tear-off and replacement when the underlying structure is sound.
Repair vs. Restoration: Making the Right Call
Not every aging or leaking commercial roof needs to be replaced. Our assessment process includes a thorough inspection, infrared moisture scanning, and core sampling where appropriate to determine how much existing insulation is wet and whether the deck has sustained structural damage. Based on this data, we give you a clear, honest recommendation:
- Targeted repair — when failures are isolated to specific areas (flashing, seams, penetration details) and the membrane is otherwise in good condition
- Restoration — when the membrane is aging but structurally sound; applying a coating or new cap sheet extends service life significantly at a fraction of replacement cost
- Full replacement — when wet insulation is widespread, the deck is compromised, or the system has reached the end of useful life
Long Island Roofing Systems We Repair
Long Island's commercial building stock encompasses a range of roofing system types, each requiring specific repair techniques:
Modified Bitumen & Built-Up Roofing (BUR)
Modified Bitumen and multi-ply BUR systems are common throughout Nassau County and older Suffolk County commercial districts. We repair blistering, alligatoring, seam separations, and flashing failures on these systems, and can extend their service life through cap sheet overlays and fluid-applied restoration coatings.
TPO & Single-Ply Membrane Repair
TPO and EPDM systems installed across Long Island's industrial and commercial parks can develop seam failures, punctures, and flashing issues over time. We use heat-welded repairs for TPO and compatible EPDM sealants and patches to restore watertight integrity without full replacement.
Flashing & Penetration Repairs
The majority of commercial roof leaks on Long Island originate at flashings — parapet walls, HVAC curbs, skylights, drains, and pipe penetrations. Coastal salt air accelerates flashing degradation faster than inland markets. We specialize in comprehensive flashing repairs and replacements using materials rated for coastal exposure.
Serving Nassau & Suffolk County
Our repair and restoration crews serve commercial properties throughout Long Island — Nassau County communities including Hempstead, Garden City, Mineola, Hicksville, Massapequa, Freeport, and Valley Stream, as well as Suffolk County locations including Farmingdale, Melville, Hauppauge, Ronkonkoma, Islandia, Bay Shore, Bohemia, and beyond.

Frequently Asked Questions
We conduct a thorough inspection including infrared moisture scanning and core sampling where needed. If wet insulation is localized and the membrane has remaining service life, repair or restoration is usually the right call. We give you the data and let you decide — no pressure toward the more expensive option.
We repair all commercial flat-roof systems common on Long Island, including TPO, EPDM, Modified Bitumen, and built-up roofing (BUR). We also repair and replace flashings, expansion joints, and penetration details on all system types.
Yes. Multiple leaks often indicate systemic issues — aging membrane, widespread flashing failures, or deteriorated seams — rather than isolated damage. We assess the full roof and provide a repair scope that addresses the root causes, not just individual leak points.
Significantly. Salt air corrodes metal flashings and fasteners faster than inland markets, so we pay close attention to flashing material selection and coating protection on Long Island repairs. We use stainless steel fasteners and marine-grade sealants where appropriate for coastal-zone properties.
