Attachment Limitations:
5.8.1
For use under mechanically attached NON-TILE prepared roof coverings, attachment shall be in accordance with
the manufacturer’s installation instructions, but – for mechanically attached underlayments or base sheets - not
less than FBC 1507.1.1 or R905.1.1.
5.8.2
For use under tile roof systems, attachment shall be in accordance with the manufacturer’s installation
instructions, but – for mechanically attached base sheets - not less than:
• FRSA/TRI Florida High Wind Concrete and Clay Roof Tile Installation Manual, Sixth Edition, Appendix A,
Table 1 (for Two-Ply Asphalt Applied Hot Mop Underlayment)
or
• Table 4A or Table 4B herein (for other underlayment systems).
5.8.3
Wind Resistance for Underlayment Systems in Tile Roof Applications:
The following wind uplift limitations apply to underlayment systems that are not prescriptive in the FRSA/TRI
Florida High Wind Concrete and Clay Roof Tile Installation Manual, Sixth Edition. The Maximum Design Pressure
is 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).
5.8.3.1
Direct-to-Deck:
The maximum design pressure for the selected assembly shall meet or exceed that required under FRSA/TRI
Florida High Wind Concrete and Clay Roof Tile Installation Manual, Sixth Edition, Appendix A, Table 1A or the
critical (highest) design pressure determined in accordance with FBC 1609 or FBC Residential Chapter 3.

Alternatively, the maximum design pressure for the selected assembly shall meet or exceed at least the Zone 1
design pressure determined in accordance with FBC 1609 or FBC Residential Chapter 3. Elevated pressure zones
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
