shall be installed in compliance with the
codied 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 roong 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
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.
