ROOF SURFACE PREPARATION
RoofKit White Reinforced Membrane will adhere to insulation
boards compatible with RoofKit adhesives (this does not
include polystyrene insulation). The roof membrane will
adhere to plywood, OSB (Oriented Strand Board), one-half
inch (1/2") high-density wood fiberboard, and concrete. If
polystyrene insulation is used, cover the insulation with
one-half inch (1/2") high-density wood fiberboard. Butt all
insulation boards together, staggering all of the joints. All
spaces larger than 1/4" must be filled to provide a uniform,
smooth surface.
Fastening Screws and Plates shall be applied at the minimum
rate of ten (10) per 4 ft. x 8 ft. board of insulation, and five
(5) per 4 ft. x 4 ft. board, or as required by the insulation
manufacturer. When installing insulation around the perimeter,
the fastening pattern is one (1) fastening screw and plate every
two (2) square feet (16 per 4 ft. x 8 ft. board). Examples
of fastening patterns are shown in Figure 1. NOTE: Extra
fastening screws should be installed around protrusions such
as pipes, chimneys, skylights and irregularities in the roof
deck.
Do not install more insulation than can be covered with
RoofKit White Reinforced Membrane by the end of the day.
Reroofing over a wet substrate is not good roofing practice.
All wet materials should be removed and replaced prior to the
installation of new materials.
The roof surface must be dry. Moisture will cause poor mem-
brane adhesion and blistering.
The roof surface should be swept to remove dirt, dust and other
loose particles.
Good roofing practice dictates that the roof surface must have
positive drainage of at least 1/8" in 12 inches.
