Sheet Layout Options for Induction Welded Roof Installation | Roofing it Right with Dave & Wally

Dave and Wally walk one completed roof section of the project and point out specific details of the installation, including how the contractor has addressed walls, end laps and T-Joint patches. They discuss the pros and cons of each installation consideration. Induction welding is an all-in-one attachment system for TPO and PVC membrane uses the same fastener and plate to secure the membrane and insulation in-place without penetrating the membrane. GAF’s Roofing It Right series “Induction Welded Roof Installation” features Dave & Wally walking us through each stages of a commercial TPO roofing project that is using an induction welding system.
