ROOF REPAIR GUIDE
Temporary or Emergency Repair
In the event that the Flex Roofing System becomes damaged the build-
ing owner may be required to make temporary repairs to the roof system,
which will not affect the warranty coverage.
Materials
Flex one component gun grade moisture curing polyurethane sealant.
Flex Thermoplastic Reinforced TPO Plus
® 45 mil, 60 mil, or 80 mil Flashing
Membrane. A detergent cleaner such as Flex orange power cleaner or
trisodium phosphate is applied to remove residual dirt. Final cleaning is
achieved with a solvent cleaner such as Flex Weathered Membrane
Cleaner
™ , Scotch Brite Pads ® , or clean white cotton rags.
Procedure
Locate the damaged area. Prepare the surface by removing debris,
contaminants and ballast from the area of the membrane or flashing to be
repaired. The area should extend beyond the perimeter of the patch to
provide an ample-sized clean work area. Scrub the repair area clean with
an approved cleaner.
Dry the repair area with a rubber squeegee and clean, absorbent, lint-free
cloths. Cut a patch from a piece of Flex TPO Flashing Membrane. The
patch should extend past any part of the damaged area by a minimum
of 4.” Round off the corners of the patch. Wipe the area of the existing
membrane to receive the patch and the underside of the patch material
with a clean, absorbent, lint-free cloth dampened with a solvent such as
Flex Weathered Membrane Cleaner. Do not pour the solvent directly on
the membrane. Wipe the repair area clean and allow the area to air dry.
Fill the damaged area with Flex gun grade sealant. Apply Flex gun grade
sealant to the back of the Flex TPO Flashing Membrane patch. Press the
Flex patch into place over the damaged area and roll firmly with the rubber
faced hand roller. Caulk the outside edges of the patch with a bead of the
Flex sealant.
Note: This procedure is considered a temporary repair. A permanent hot
air welded patch can be installed at a later date, by an approved applicator,
directly over the existing temporary patch.
