the result of testing for wind load resistance based on allowable wind loads and reflects the ultimate passing
pressure divided by 2 (the 2 to 1 margin of safety per FBC 1504.9 has already been applied). Refer to FRSA/TRI April
2012 (04-12), Appendix A, Table 1A or FBC 1609 for determination of design wind loads.

5.6.1.1 For mechanically attached Base Sheet, the maximum design pressure for the selected assembly shall meet or
exceed that required under FRSA/TRI April 2012 (04-12), Appendix A, Table 1A.
Alternatively, the maximum design pressure for the selected assembly shall meet or exceed the Zone 1 design
pressure determined in accordance with FBC 1609. In this case, Zones 2 and 3 shall employ an attachment density
designed by a qualified design professional to resist the elevated pressure criteria. Commonly used methods are
ANSI/SPRI WD1, FM Loss Prevention Data Sheet 1-29 and Roofing Application Standard RAS 117. Assemblies
marked with an asterisk* carry the limitations set forth in Section 2.2.10.1 of FM Loss Prevention Data Sheet 1-29

6. INSTALLATION:
6.1 GAF Roof Underlayments shall be installed in accordance with GAF published installation instructions subject to
the Limitations set forth in Section 5 herein and the specifics noted below.
6.2 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 and prime the substrate (if applicable).
6.3 Install self-adhering underlayments when ambient temperatures are minimum 45°F and rising.
6.4 All metal surfaces shall be primed with Matrix™ 307 Premium Asphalt Primer or alternate GAF accepted ASTM
D41 primer prior to application of self-adhering membranes.
6.5 Deck-Armor™ Premium Breathable Roof Deck Protection:
6.5.1 Shall be installed in compliance with the requirements for ASTM D226, Type I or II underlayment in FBC Table
1507.1.1 or R905.1.1 for the type of prepared roof covering to be installed, considering the wider sheet-width for
double-layer applications.
6.5.2 Fasteners:
Minimum fasteners shall be 1-inch diameter plastic-capped corrosion resistant nails or 1-inch diameter plastic-
capped, corrosion resistant staples, unless restricted by Code.
Code Reference: The Exception statement in FBC 1507.1.1 and FBC R905.1.1 states: “…except metal cap nails shall
be required where the ultimate design wind speed, Vault, equals or exceeds 150 mph.”
6.5.3 Slopes of 4:12 or greater:
End (vertical) laps shall be minimum 6-inches and side (horizontal) laps shall be minimum 4-inches. End (vertical)
laps shall be offset from course to course not less than 6 feet.
Minimum attachment shall be in accordance with FBC Table 1507.1.1 or R905.1.1. Secure end laps 6-inch o.c.
When batten systems are to be installed atop the underlayment, the underlayment need only be preliminarily
attached pending attachment of the battens.
6.5.4 Slopes of 2:12 to less than 4:12:
End (vertical) laps shall be minimum 6-inches and side (horizontal) laps shall be minimum 28.5-inches (for 54-inch
wide rolls) or minimum 25.5-inches (for 48-inch wide rolls). End (vertical) laps shall be offset from course to course
not less than 6 feet.
Begin by fastening a full-width along the eaves or install full-width leak barrier. Place a full-width sheet over the
starter, completely overlapping the starter course. Continue upslope, maintaining minimum 28.5-inch side laps
(for 54-inch wide rolls) or minimum 25.5-inch side laps (for 48-inch wide rolls), resulting in a double-layer
application.
Minimum attachment shall be in accordance with FBC Table 1507.1.1 or R905.1.1. Secure end laps 6-inch o.c.
When batten systems are to be installed atop the underlayment, the underlayment need only be preliminarily
attached pending attachment of the battens.
6.5.3 Optional, or if required by the Authority Having Jurisdiction: Install a leak barrier of Liberty™ SBS Self-Adhering
Base/Ply Sheet; StormGuard® Film Surfaced Leak Barrier or WeatherWatch® Mineral Surfaced Leak Barrier 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 the underlayment. Along the rake, install the underlayment, leaving
6 to 8-inch of the deck exposed, and then install the leak barrier over the underlayment and exposed decking. At
other areas, install the leak barrier over the underlayment.
