GeneRal InfoRMaTIon This APPLICATION GUIDE has been designed to give the installer a GENERAL DESCRIPTION of a RoofKit fully adhered white roof system. This APPLICATION GUIDE is intended as a reference aid only and is not intended or meant to be all-inclusive. RoofKit User Cautions and Warnings! • The White Membrane is slippery especially when wet, dusty or covered with snow, frost or ice. Please read and follow all cautions and warnings, including notice on the white membrane roll.
• Avoid adhesive contact with eyes. Safety glasses should be worn. If adhesive comes in contact with eyes, flush for 15 minutes and call a physician. • Care must be taken with fasteners that penetrate the deck to avoid contact with electrical wiring and plumbing. • Reroofing over a wet substrate is not good roofing practice. All wet materials should be removed before proceeding with the installation of new materials. • Condensation may occur when applying adhesives at temperatures below 40o F.
ReCoMMended Tools The following list is for reference only, as tools and equipment may vary from project to project: • • • • • • • • 2-inch steel or hard roller Soft bristle push broom Scissors Chalk line Tape measure Solvent resistant rubber gloves Stir stick for adhesives 9-inch paint roller frame and several large nap, solvent compatible roller covers • Caulk gun • Extension Ladder • Screw gun and hammerdrill RoofKIT PRodUCTs avaIlable • RoofKit White Reinforced Membrane (45 mil thickness) available 6'
• RoofKit White Membrane Patch and Corner Cover Kit (6) 8" Repair Patches, 1 pint seam primer, scrub pad, 1 seam roller, and 2 wipe cloths • RoofKit White Skylight Flashing 8" x 14' • RoofKit Fastening Screws and Plates 100 of each; both 3" Roof sURfaCe PRePaRaTIon RoofKit White Reinforced Membrane will adhere to insulation boards compatible with RoofKit adhesives (this does not include polystyrene insulation).
FIGURE 1 - Fastening Pattern InsTallaTIon Unroll the RoofKit White Reinforced Membrane over the substrate so that the sheet is in the desired position and is wrinkle free. If more than one roll of membrane is required, subsequent rolls must over lap the prior roll a minimum of three inches (3") for seaming. Start at the low side of roof if seaming rolls. Care should be taken to ensure the membrane overhangs the perimeter of the roof at least three inches (3").
adhesive is curing. Repositioning of the membrane is possible while the adhesive is still wet. After the adhesive begins to set-up (approximately 20 to 35 minutes) apply pressure with a push broom to ensure good contact. This application requires a porous substrate, such as High Density Fiberboard, OSB or plywood. Contact Application Method: For vertical or horizontal applications. Open and thoroughly stir the White Membrane Water Based Bonding Adhesive.
seaMInG MeMbRane The top membrane should overlap the bottom sheet by 3". Mark a line ½ inch out from the edge of the top roof membrane. Fold back the top 3" overlap and clean both surfaces of the area to be seamed with the RoofKit Seam Primer using scrubbie pad and allow to dry completely. Fold the top membrane sheet back to expose the seam area. (HINT: A small piece of seam tape that is tacky on both sides is useful to tack the membrane back.
TeRMInaTIon baR When using the Termination Bar to secure the White Reinforced Membrane over the edge of the roof, make sure that the sheet extends a minimum three inches over the roof’s edge. Center the bar in the 3” overhang and secure with fastening screws. The screws should be positioned through the pre-drilled holes along the length of the Termination Bar. Use a utility knife, to trim any excess membrane below the bar for a finished look.
Use roller to ensure good contact of top half of corner. Step 3 Remove paper backing from bottom half of corner. Step 4 Gently work the bottom half of corner into place. Be sure not to overstretch. Step 5 Use roller to ensure good contact throughout the completed corner. Step 6 Use RoofKit White Caulk around all edges of the completed corner. Step 7 InsIde CoRneR deTaIl Using scrub pad, clean entire area with RoofKit Seam Primer. Allow to dry.
Fold 8" round corner in half, remove top half of paper backing and position ½ of each top fold into the corner. Step 2 Use roller to ensure good contact of top half of corner. Step 3 Fold bottom half of corner to create a flap or “pig's ear". Step 4 Remove the remaining paper backing and press the flap against itself sealing the flap or “pig's ear". Step 6 Step 5 Clean the area behind the flap and apply RoofKit MultiPurpose Adhesive to the back side of the flap. Allow adhesive to dry.
Step 8 Use RoofKit White Caulk around all edges of the completed corner. CoveR sTRIP Step 1 Clean and/or prime the area to be covered. CAUTION: Wear protective gloves when using solvent/primer. Step 2 Center coverstrip over the prepared surface. Peel back about 8" of paper to expose the adhesive side of the strip. Step 3 Remove release paper at a 45° angle. Step 4 Gently mate the coverstrip by hand, avoiding stretching or wrinkles.
Use the seam roller to ensure good contact. Final rolling should be both perpendicular, then parallel to the length of strip. Step 6 WHITe PIPe booT WITH sTeel ClaMP Clean area around pipe with RoofKit Seam Primer. Step 1 With a scissors, cut proper diameter for pipe boot. Step 2 Slide pipe boot over pipe, press into place and remove self-adhesive paper. Step 3 Roll base of pipe boot with seam roller and install steel clamp.
PaTCHes aT T-JoInTs A T-Joint is formed when two layers of RoofKit White Roof Membrane form a seam that travels under, or over, a third layer of membrane. The center of the “T" is where the middle layer ends and the top layer bridges over the middle layer. This T-Joint can provide an opportunity for water to seep under the membrane.
Keep the bottom course of shingles a minimum of four inches (4") above the roof angle change. To adhere the bottom course of loose shingle tabs to the membrane, lift each tab and apply a bead of RoofKit White Membrane Caulk. PaTCHInG RoofKIT WHITe RoofInG MeMbRane Using scrub pad, clean entire area with RoofKit Seam Primer. Allow to dry. Step 1 Remove paper backing from 8" round patch and position the patch over the damaged area. Step 2 Use the seam roller to ensure good contact.
GlossaRY BRIDGING: Occurs when the membrane is unsupported at a juncture or angle change. Moisture condensing on the bottom of the membrane can cause further delamination. Areas where bridging occurs should be repaired and re-flashed. COVER STRIP: Six inch (6") wide cured white membrane with butyl tape laminated to one side. Used when stripping in metal edge details, repairing cuts in the field membrane. FASTENING SCREWS AND PLATES: Used to mechanically attach (fasten) the insulation board to the roof deck.
WHITE PIPE BOOT AND CLAMP: Pre-molded white boot. The most cost effective way to flash pipe protrusions. The stainless steel clamp is used to secure the top of the pipe to the Pipe Boot. WHITE CAULK: Applied at the top of all Fastening/ Termination Bar applications; at the top of Pipe Boots and after the Pipe Boot Clamp has been installed, seams, patches, and to adhere shingle tabs to RoofKit White Roofing Membrane.
