Installation Instructions
Round Base/Flasher®
STEP 1: Cut to pipe diameter marked on Flasher® (this is approximately 20% smaller than the diameter of the pipe).
STEP 2: Slide the Flasher® down the pipe, using water to lubricate if necessary.
STEP 3: Form & bend the aluminum base of the Flasher® to fit the surface of the roof.
STEP 4: Seal the Flasher® by applying urethane or silicone sealant between the flashing & the roof. Use a large slot screwdriver to press the base
down tightly.
STEP 5: Fasten the Flasher® with weather-resistant fasteners to complete the seal.
Square Base Flashing/Masterflash®
STEP 1: Trim opening to 20% smaller than pipe diameter.
STEP 2: Slide down over pipe.
STEP 3: Apply urethane or silicone sealant between the Masterflash® and roof.
STEP 4: Press down, bending the flashing to fit irregularities. Use a large slot screwdriver to press into tight angles.
STEP 5: Use fasteners to finish sealing.
Round Base Retrofit Flashing/Retrofit Dektite®
STEP 1: Begin cutting opposite of the mechanical locking joiner. Cut through the joiner with tin snips.
STEP 2: Wrap the flashing around the pipe. Engage the top section of the joiner first, then proceed down until the joner is completely engaged.
STEP 3: Crimp joiner tightley, starting at the top by squeezing joiner "fingers" with pliers.
STEP 4: Apply sealant to the underside of the ribbed aluminum base. Press Retrofit Dektite against contours of the penl configuration.
STEP 5: Attach the Retrofit Dektite® to the panel with self-drilling screws. Screws should be spaced as necessary to avoid gaps between the base and the panel.
STEP 6: Apply additional sealant around the top of the flashing and along the mechanical locking joiner seam.
Square Base Retrofit Flashing/Retrofit Masterflash®
STEP 1: Choose appropriate size Retrofit Masterflash®. If necessary trip opening to be about 20% smaller than the pipe diameter.
STEP 2: Wrap the flashing around the pipe and install all snap rivets to seal the flange.
STEP 3: Press the Retrofit Masterflash® down, bending it to conform to the roof profile and/or roof irregularities. A blunt tool will help press the flashing into tight roof angles.
STEP 4: Apply silicone or urethane sealant between the base of the flashing and the roof.
STEP 5: Use fasteners to complete the sealing. For UPC installation, fastener spacing shall not exceed 1 ½".
STEP 6: Install supplied cable tie at the upper-most part of the flashing and apply sealant to any gaps.
