About
Keystone Commercial Roofing Contractors brings over 20 years of commercial roofing experience to the New York City and Paterson, NJ metro market, serving facility managers and property owners across office buildings, retail centers, healthcare facilities, and government properties. The company has installed millions of square feet of commercial roofing systems, making it a volume-tested option for flat and low-slope roof projects throughout the region. Keystone's core service offering covers the full spectrum of commercial membrane systems, including TPO, PVC, EPDM, modified bitumen, and built-up roofing (BUR), as well as cool roof coatings and liquid-applied roofing solutions — giving facility managers flexibility when evaluating system replacements or re-roofing projects. Sheet metal roofing and single-ply installations round out their installation capabilities. For property managers dealing with active leaks or storm damage, Keystone operates a 24/7 emergency response team, a critical feature for minimizing business interruption in occupied commercial buildings. Routine roof maintenance programs are also offered, addressing the ongoing needs of facility managers responsible for extending membrane life and avoiding costly capital replacements. The company explicitly services government and private sector clients, as well as health sector facilities — building types that typically require documented workmanship standards and reliable scheduling. Their NYC-area focus means crews are experienced with the urban flat-roof landscape common to commercial properties in Manhattan, the boroughs, and northern New Jersey. Keystone positions itself around a 100% customer satisfaction commitment and first-time-right workmanship on every project. Facility managers evaluating commercial roofing contractors in the Paterson or greater NYC market will find Keystone a broadly capable provider for membrane installation, repair, maintenance, and emergency response across a wide range of commercial roof system types.
