Compliance Statement: Compliance Statement: Compliance Statement: Compliance Statement: This product as described has demonstrated compliance with Florida Building Code 2023,
1504.3.2 (nonnonnonnon----HVHZHVHZHVHZHVHZ), as required by FL Rule 61G20-3, method 1D.
This product as described has been tested and demonstrated compliance with:
• UL580 – Test for Uplift Resistance of Roof Assemblies
• UL 1897 – Uplift test for roof covering systems
Design Process:Design Process:Design Process:Design Process: Compare the maximum allowable loads on page 1 to the ASD uplift pressures for the project to
determine sufficiency and installation requirements.
Alternatively, as an option, the load tables in this report provides one prescriptive option for the fastening requirement
for the applicable wind loads for roofs within the parameters described.
For roofs outside of the listed parameters, design wind loads shall be determined as required by FBC 1609, ASCE 7, or
other design code in force, using allowable stress. These load tables are based on ASCE 7-22. Use of these tables assumes
that the structure is: Enclosed and conforms to wind-borne debris provisions and is a regular shaped building and is not
subject to across-wind loading, vortex shedding, or instability; nor does it have a site location for which channeling or
buffeting warrant consideration
Engineering analysis may be completed by other licensed engineers for project specific approval by local authorities
having jurisdiction.

Use of Load Use of Load Use of Load Use of Load Tables:Tables:Tables:Tables: These load tables are provided as a courtesy to
provide one possible prescriptive option for a generic, typical
structure without calculating the design pressures.
For structures outside the parameters of these load tables (e.g.
height above 30 feet), calculate the required allowable design
pressure and compare to the maximum allowable loads shown on
page 2. These load tables shall not be construed to in any way limit
the installation of this product to the cases shown.
