6. Precautions & Limitations:
Depending on roof pitch and surface conditions (wet, dusty, frost), the coefcient of friction may change, and can
become slippery. Use caution.
Use caution when walking on roof deck and use OSHA compliant fall protection.
Do not walk or stand on ShingleLayment until it is attached to roof deck according to installation instructions.
Shingle print pattern is not intended for use as an installation grid for nal roong surface shingles.
ShingleLayment is not designed as a primary roof covering. Exposure beyond 30 days without nal roof covering may subject the
sheet to jobsite abuse, chemical exposure, and severe weather.
ShingleLayment may not be used in any exposed application such as crickets, exposed valleys, or exposed roof to wall details.
Attic spaces must be property ventilated in accordance with the local Building Code.
Minimum roof pitch: 2:12 (9.4°).
Installation for batten-secured
roof cover:
When battens are installed over Grip-Rite
ShingleLayment, the underlayment need
only be preliminarily attached in advance
of batten installation. Ensure preliminary
underlayment attachment does not
interfere with batten locations. Where
seams or joints require sealant or adhesive,
use only high quality, low solvent asbestos
free plastic roong cement meeting ASTM
D4586, Type I. Install a leak barrier of
ASTM D1970 or approved equal at vulnerable leak areas, including but not limited to eaves, valleys, rakes, skylights and dormers. At
eaves and valleys, install the leak barrier prior to installation of ShingleLayment. Along the rake, install ShingleLayment leaving 6 to 8
in. of the deck exposed, and then install the leak barrier over the ShingleLayment and exposed decking. At other areas, install the leak
barrier over the ShingleLayment.
