Technical Documentation:
This product has been tested to the UL 580 standard by Architectural Testing (now Intertek
Testing, TST-1527), F7247.02-450-44 as referenced in FL 17022.09-R7.
Compliance Statement:
This product as described has demonstrated compliance with Florida Building Code 2020,
1504.3.2 (non-HVHZ), 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:
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 7-16.
Use of these tables assumes that the structure is:
• Enclosed and conforms to wind-borne debris provisions and is a regular shaped building
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.
Certification of Independence:
David Eng, PE and Timberlake Cove, LLC do not have, nor will acquire a financial interest in any company
manufacturing or distributing products under this evaluation_ The same entities do not have, nor will
acquire, a financial interest in any other entity involved in the approval process of the product.
Exclusions and Limitations:
Design of deck and roof structure (to include attachment of plywood or wood plank) shall be completed by
others. Fire classification and shear diaphragm design are outside the scope of this evaluation. Accelerated
weathering/salt spray is outside the scope of this evaluation.
This report is limited to compliance with structural wind load requirements of FBC 1504.3.2, as required by
Rule 61G20-3. Neither Timberlake Cove nor the manufacturer shall be responsible for any conclusions,
interpretations, or designs made by others based on this evaluation report. This report is limited solely to
documenting compliance with Rule 61G20-3, and makes no express or implied warranty regarding
performance of this product_ Installation shall be subject to the local building code and authority having
jurisdiction; this report shall not be construed to supersede local codes in force.

Instructions:
Select the appropriate load table that applies to the
structure in question.
Determine the design wind speed for the project
location.
Use the attachment method indicated for that
windspeed within each roof zone.
NOTE: ASCE 7-16 and FSC 2020 adopt a 7-zone concept.
For the load tables below, the worst case was taken
for each zone and reported using the standard zones
1-2-3:
Zone 1 includes zones 1 and 1'
Zone 2 includes zones 2e, 2r, and 2n
Zone 3 includes zones 3e and 3r
Combining these zones creates a clear, simple
scheme, at the expense of some design efficiency.
Contact the manufacturer for further information,
or consult a licensed design professional.
