LIMITATIONS
1. Fire classification is not within the scope of this evaluation.
2. The roof deck and the roof deck attachment shall be designed by others to meet the minimum design loads
established for components and cladding and in accordance with FBC requirements.
3. Foam plastic insulation shall be installed in accordance with the FBC Section 2603.4.
4. In the HVHZ, fastener spacing for insulation attachment is determined using a Minimum Characteristic Force
(F’) of 275 lbf as demonstrated via testing to TAS 105. If the field tested fastener value is below 275 lbf,
then insulation attachment shall not be acceptable.
5. In the HVHZ, fastener spacing for base sheets or membrane attachment shall meet the minimum fastener
resistance value and the MDP for the specified roof system. It is permissible for a qualified professional to
submit a revised fastener spacing utilizing the withdrawal resistance value obtained from TAS 105 testing
and calculations performed in accordance with RAS 117 and/or RAS 137, when the fastener resistance is
found less than required.
6. In the HVHZ, if mechanical attachment through the lightweight insulating concrete to the structural deck is
proposed, a field fastener withdrawal test shall be conducted in compliance with TAS 105 to determine
equivalent or increased attachment densities. Revised fastener densities shall b e submitted utilizing the
withdrawal resistance value obtained from TAS 105 testing and calculations performed in accordance with
RAS 117 and/or RAS 137.
7. For assemblies containing mechanical attachment, the allowable uplift pressure for the selected roof system
shall meet or exceed the minimum design loads as determined in accordance with the FBC Chapter 16. For
perimeter and corner roof zones 2 and 3, the attachment density may be increased by a qualified design
professional, as necessary, to meet the d esign pressure requirements in these areas. In the HVHZ,
calculations shall be conducted in compliance with RAS 117 and/or RAS 137.
8. Reroofing applications shall be examined in accordance with FBC Section 151 1 outside of the HVHZ and
FBC Section 1521 within the HVHZ. For mechanically fastened roof systems, a field withdrawal resistance
test (TAS 105 in the HVHZ; ANSI/SPRI FX-1 or TAS 105 in the non-HVHZ) shall be conducted by a qualified
professional to ensure the fastener meets the minimum design load req uirements of the roof system. For
adhered roof systems, a field uplift resistance test (TAS 124 in the HVHZ; ASTM E 907, FM LPDS 1 -52,
ANSI/SPRI IA-1, or TAS 124 in the non-HVHZ) shall be conducted to confirm conformance of the existing to
the minimum design loads.
9. For assemblies containing fully adhered or ribbon adhered attachment, or where extrapolation of the roof
system is not permitted, the MDP for the selected roof system shall meet or exceed the minimum design
loads as determined in accordance with the FBC Chapter 16 without augmentation.
10. Installation of the evaluated products shall comply with this report, the FBC, and the manufacturer’s
published application instructions. Where discrepancies exist between these sources, the more restrictive
and FBC compliant installation detail shall prevail.
11. The minimum roof slope shall be 1/4:12 for new construction.
12. All products listed in this report shall be manufactured under a quality assurance program in compliance with
Rule 61G20-3.
13. Fasteners applied in rows may impart concentrated loads to structural components of the
building. Designers should consider the fastener spacing of the roof system in relation to the spacing of
structural supports when selecting a roof system.
