Installation Instructions

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. To avoid problems at this area, a patch should be

installed as follows:

Clean the membrane with Seam Primer at least four inches (4")

in all directions from the T-Joint and allow to dry.

Using the White Membrane Patch centered over the junction

of the three layers of membrane, remove paper backing and

carefully smooth in by hand to avoid wrinkling and roll with

a steel or hard roller. Use RoofKit White Membrane Caulk to

seal all edges.

FIELD SEAM AT VERTICAL CHANGE

Where a field seam makes a sharp angle change (turns up

a wall), a White Membrane Patch is to be adhered over the

seam. Follow standard installation for patches and clean the

membrane with RoofKit Seam Primer and scrub pad. Install

the patch so that the patch is centered on the seam. Finally, use

RoofKit White Membrane Caulk to seal all edges.

ROOFKIT MEMBRANE TO SHINGLE TRANSITION

When installing a RoofKit White Roofing Membrane system

with a tie-in to an existing shingle roof, remove a minimum

of three (3) courses of shingles. Install White Membrane

Coverstrip up side down at the base of the angle change and

fasten using RoofKit Plates and screws 12" on center, leaving

the paper backing on the Cover Tape. Scrub Tape Primer on

corresponding back of membrane and allow to dry. Carefully

peel the release paper off the inverted or up side down Cover

Strip. Mate the back of the membrane to the exposed white

tape as you finish installing up the wall. Adhere the mem-

brane onto the sloped roof deck. Peel the top of the mem-

brane back and apply a bead of RoofKit Water Stop between

the membrane and the deck. Nail the top of the membrane

every six inches (6") and install the shingles over the RoofKit

membrane.
