Commercial roofing accessories & flashings FAQs
Flashings on a commercial roof range from tapes to custom membrane material to specialized liquid flashing solutions. GAF flashing offerings include EverGuard™ TPO Primerless 6” Cover Tape, Utility Flashing Strip, EverGuard® TPO Cover Tape, EverGuard® TPO RTA (Roof Transition Anchor) Strip, EverGuard® TPO and EverGuard Extreme® TPO Heat-Weldable Cover Tape, EverGuard® and EverGuard® Extreme TPO UN‑55 Detailing Membrane, EverGuard™ PVC 50‑Mil Utility Flashing Membrane, EverGuard™ PVC Coated Metal Sheets, and EverGuard® & EverGuard Extreme® TPO Coated Metal Sheets as well as liquid flashings including MajorSeal™ Liquid Flashing and GAF PMMA Flashing Resin.
All of them. Virtually all building codes (such as the International Residential Code) strictly require all roof penetrations to be protected by flashing to prevent water entry and structural rot.
GAF accessories are engineered and manufactured to be compatible with specific GAF roofing systems and guarantees. For example, our TPO accessories are compatible with our EverGuard® TPO membrane systems and so on. See individual data sheets for compatibilities and installation details.
