Flat roofs on commercial buildings deal with challenges residential roofs don't: rooftop HVAC units, exhaust fans, plumbing penetrations, satellite equipment, foot traffic, and ponding water. Old Westbury Roofing & Maintenance has the training and equipment to handle all of it across Old Westbury.
We install every major commercial roofing system: TPO single-ply, EPDM rubber membrane, PVC for chemical-resistant applications, modified bitumen for high-traffic roofs, and built-up roofing for proven long-term performance. Material selection depends on your building, budget, and specific exposure conditions.
