Roofing it Right: EverGuard® TPO with MembraneShield
Dave & Wally share the features, advantages and applications of EverGuard® TPO with MembraneShield. They provide an installation demonstration of the products and show you tips and techniques to help you install it correctly.
MembraneShield temporary dirt-blocking film
Factory-applied, easy to remove monolayer protective sheet for TPO membrane. Read full application instructions at gaf.com/membraneshieldinstall before using or installing this product.
Installation Steps
Installation instructions must be followed exactly in the order of steps as indicated. NOTE: MembraneShield covers the entire length of the EverGuard® TPO membrane with the exception of a portion of the side lap, which is left exposed for welding.
-
Unroll & Install First Roll
Unroll and install a first roll of roofing membrane over the roofing substrate, according to your selected installation method. -
Unroll & Install Additional Rolls
Unroll and install additional roofing membrane rolls next to the first roofing membrane, making sure only the exposed side lap is being overlapped by the roofing membrane next to it (typically either 3” or 6”, depending on the system being installed.)
Weld the roofing membranes at the overlapped area following best practices.
-
End Laps
At the end laps, unroll and lay a second roofing membrane roll over the roofing substrate so that the second roofing membrane overlaps the first roofing membrane about 3” for smooth TPO.
Pull up enough monolayer protective sheet from the first membrane at the overlapped area to allow the exposed first membrane to make close direct contact with the underside of the second roofing membrane.
Weld the first and second membranes to each other at the overlapped area following best practices.
-
Peel the MembraneShield
When the roof installation is complete, peel off the MembraneShield protective monolayer sheet within 90 days. Residual water-insoluble acrylic-based adhesive on the membranes should not be removed.
