New Rubber Layer on Commercial Flat Roof Installation in Queens
RH Renovation NYC completed a precision commercial flat roof installation featuring a high-performance EPDM rubber membrane for a commercial property located in Queens, NY. Commercial low-slope and flat roofing systems across New York’s busy urban centers face intense environmental stressors—including thermal expansion and contraction from extreme seasonal temperature shifts, aggressive ultraviolet (UV) radiation, high wind-shear across expansive roof decks, and the chronic hazard of standing water (ponding) that exploits minor membrane seams.
This project was engineered to strip away an exhausted, leak-prone commercial roofing assembly, restore the underlying substrate, and install a resilient, seamless single-ply rubber membrane designed to guarantee superior waterproofing, enhance commercial energy efficiency, and protect the building’s structural assets for decades.
Comprehensive Scope of Work & Commercial Installation Protocol
To ensure absolute weather-tight security and strict compliance with New York City commercial building codes, our licensed and insured commercial flat roofing specialists executed a rigorous, multi-phase installation workflow:
Complete Tear-Off & Substrate Rehabilitation: The failing legacy commercial roofing membrane, saturated insulation layers, and deteriorated flashings were completely stripped down to the structural roof deck. Technicians performed a detailed structural audit of the underlying steel, wood, or concrete deck, repairing or replacing compromised sections to establish a solid, load-bearing foundation.
Tapered Insulation & Drainage Optimization: Rigid polyisocyanurate (ISO) insulation boards and tapered sump crickets were installed to eliminate hydrostatic pooling zones, directing storm runoff efficiently toward internal roof drains, scuppers, and perimeter scupper boxes.
Commercial EPDM Membrane Application: A premium, high-gauge EPDM (Ethylene Propylene Diene Terpolymer) single-ply rubber membrane was rolled out across the expansive deck. Using advanced bonding adhesives and specialized primer-seam tape technologies, the membrane was expertly secured to deliver seamless, watertight elasticity capable of withstanding severe thermal shock.
Perimeter Edge Metal & Flashing Detailing: All critical commercial transition points—including parapet walls, HVAC equipment curbs, expansion joints, pipe penetrations, and commercial gravel stop edge metal—were reinforced with custom counter-flashing and uncured EPDM flashing to eliminate the industry’s most common commercial leak vectors.
Final Quality & Compliance Audit: A rigorous multi-point inspection verified that all seam welds, mechanical anchorages, and drainage paths met strict manufacturer warranty standards and NYC municipal commercial building codes, followed by a thorough site cleanup and magnetic sweep.
