| Synthetic Roofing Underlayment |
|
| The only roofing underlayment with the high performance of a synthetic underlayment,
and the finished look of a shingled roof. |
| Available in energy efficient white or tan, ShingleLayment® outperforms felt, is installer friendly, and
provides both durable temporary cover and long lasting water shedding protection. |

| 3. Product Description: |
| Composition: |
| Grip-Rite® ShingleLayment® synthetic underlayment is a lightweight, woven polypropylene underlayment
coated with a non-skid TPO. ShingleLayment possesses very high tensile and tear strength that resists tearing, ripping
and blow offs from high wind exposure. ShingleLayment can be used in any code compliant mechanically attached roofing application. |
|
| Application: |
| Grip-Rite ShingleLayment synthetic underlayment is used on steep slope roofs beneath shingles, battened tiles,
metal, slate, wood shake and shingle and simulated slate/shake prepared roof coverings as an alternate to ASTMD226,
Type I of II or ASTMD4869 asphalt felts. |
|
| Grip-Rite ShingleLayment synthetic underlayment is a water shedding device designed to reduce the occurrence of leaks
caused by wind driven rain penetrating primary roof coverings, and as temporary cover on exposed roof system. |
|
| Grip-Rite ShingleLayment synthetic underlayment is available with standard installer print pattern or
exclusive shingle-look print pattern (Patent Pending). Both print patterns feature
installation and nailing grids for easy, accurate application. |
|
| Grip-Rite ShingleLayment synthetic underlayment increases applicator productivity thanks to its low weight per
roll, and superior 10 sq. roll coverage |
|
| Grip-Rite ShingleLayment synthetic underlayment can be exposed to natural UV for up to 180 days.
Severe weather, jobsite damage, chemical exposure or other conditions may shorten exposure life. |
|
Features: |
- Shingle print pattern provides a unique finished look to exposed rood surface. Patent pending.
- Titanium dioxide white coating provides an energy saving emissive layer that reduces heat penetration.
- Tear resistant high tensile strength woven PP substrate that does not distort or belly like spun-bonded sheets.
- UV resistant.
- More that 5 times lighter than 30 lbs felt.
- Roll Cover is 4.6 times greater than felt.
- Non-skid TPO coating with high coefficient of friction.
- Printed nail pattern for easy installation.
- 20-year limited warranty.
- Available in two energy efficient colors, white or tan.
- Lighter colors reduce fabric cycling (expansion and contraction) thus reducing nail hole elongation.
- Contains no asphalt.

|
- ICC-ESR #2945
- Miami-Dade NOA 09-0527.01 8/26/09
- Florida Statewide Product Approval File No. FL12510
- AC 188
- ASTM D226

|
|
 |
| 5. Installation: |
| Grip-Rite® ShingleLayment® synthetic underlayment shall be installed compliance with the
codified requirements for ASTM D226, D4869 or D6757 underlayment for the type of prepared roof covering to be installed. |
|
| Re-fasten and 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-inch
diameter head. The use of cap staples should be limited to installations that will be covered by the
final roofing system within 60 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 flush contact between the plastic cap and the upper surface of the underlayment. Where
local code requires metal cap washers, Grip-Rite®Tin Tags are recommended. |
|
| Grip-Rite® ShingleLayment® synthetic underlayment shall be installed horizontally with
the printed side up, and with 4-inch horizontal laps and 6-inch vertical laps. Horizontal laps shall be in
a shingle pattern, running with the flow of water. |
|
| Single Layer: Roof Slope > 4:12 |
| Starting at the eave, fasten the eave edge 8-inch o.c. and vertical laps 8-inch o.c., and 24-inch o.c.
down the center or the roll. Continue upslope in a similar manner, maintaining minimum 4-inch horizontal
and minimum 6-inch vertical laps. Fasten 8-inch o.c. at horizontal laps and 8-inch o.c. at vertical
laps and 24-inch o.c. down the center of the roll. Ensure all vertical laps are staggered at least 3-feet apart. |
|
| In high wind zones (> 110 mph 3 second gust design wind speed), increase the fastening schedule to 4-inch
o.c. at horizontal laps, 4-inch o.c. at vertical laps, and 24-inch o.c. down the middle of the roll in the field 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-inch o.c. and vertical laps 8-inch
o.c. and vertical laps 8-inch o.c. Continue upslope in a similar manner, with minimum 24-inch horizontal
laps and minimum 6-inch vertical laps. Fasten 8-inch o.c. down the center of the roll. Ensure all vertical laps
are staggered at least 3-feet apart. In high wind zones (> 110 mph 3-second gust design wind speed), increase
the fastening schedule to 4-inch o.c. at horizontal laps, 4-inch o.c. at vertical laps, and 24-inch o.c. down
the middle of the roll in the field of the roof. |
|
| For batten-secured roof cover installations: |
| When battens are installed over Grip-Rite® Shinglelayment® synthetic underlayment, the underlayment need
only be preliminarily attached in advance of batten installation. Ensure preliminary underlayment attachment
does not interfere with batten locations. |
|
| Where seams of joints require sealant or adhesive, use only high quality, low solvent asbestos free plastic roofing
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 Grip-Rite®.
Along the rake, install Grip-Rite ShingleLayment® leaving 6 to 8-inch of the deck exposed, and then install the
leak barrier over the Grip-Rite® and exposed decking. At other areas, install the leak barrier over the
Grip-Rite ShingleLayment®. |

| 6. Precautions & Limitations:
|
- Depending on roof pitch and surface conditions (wet, dusty, frost), the coefficient 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 roofing
surface shingles.
- Grip-Rite ShingleLayment synthetic underlayment is not designed as a primary roof covering. Exposure
beyond sixty days without final roof covering my subject the sheet to jobsite abuse,
chemical exposure, and severe weather.
- grip-Rite ShingleLayment synthetic underlayment may not be used in and 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°).
