®
shall be installed in compliance with the
codied requirements for ASTM D226, D4869 or underlayment
for the type of prepared roof covering to be installed.
Instructions:
Re-fasten any loose decking panels and check for protruding
nail heads. Sweep the substrate thoroughly to remove any dust
and debris prior to application. Corrosion-resistant fasteners
shall be plastic cap nails or staples with a minimum nominal
1 in. diameter head. The use of cap staples should be limited
to installations that will be covered by the nal roong system
within 30 days as the membrane will be less resistive to the
elements which may result in blow-off.
Grip-Rite fasteners are recommended. Ensure fasteners
are installed at 90 degree angle to the deck with ush
contact between the plastic cap and the upper surface of the
underlayment.
Where local code requires metal cap washers, Grip-Rite
Tin-Caps are recommended.
ShingleLayment shall be installed horizontally with the printed
side up, and with 4 in. horizontal laps and 6 in. vertical laps.
Horizontal laps shall be in a shingle pattern, running with the ow
of water.
Single Layer; Roof Slope > 4:12:
Starting at the eave, fasten the eave edge 8 in. OC and vertical
laps 8 in. OC, and 24 in. OC down the center of the roll.
Continue upslope in a similar manner, maintaining minimum 4
in. horizontal and minimum 6 in. vertical laps. Fasten 8 in. OC at
horizontal laps and 8 in. OC at vertical laps and 24 in. OC down
the center of the roll. Ensure all vertical laps are staggered at
least 3 ft. apart. In high wind zones (V-asd > 110 mph 3 second
gust design wind speed), increase the fastening schedule to 4
in. OC at horizontal laps, 4 in. OC at vertical laps, and 24 in. OC
down the middle of the roll in the eld of the roof.
Double Layer; 2:12 < Roof Slope < 4:12:
Starting at the eave, fasten the eave-edge of a half-width
starter-strip 8 in. OC and vertical laps 8 in. OC Continue upslope
in a similar manner, with minimum 24 in. horizontal laps and
minimum 6 in. vertical laps. Fasten 8 in. OC along the low edge
and 8 in. OC at vertical laps and 24 in. OC down the center of
the roll. Ensure all vertical laps are staggered at least 3 ft. apart.
In high wind zones (> 110 mph 3 second gust design wind
