(~~~x/ ) EROL/ Certificate of Authorization #9503 Evaluation Report 01506.11.05 GAF Materials Corporatit:ln, ttsliso Date of Issuance: 11/07/2005 Page 4 of 5 Installation Requirements: 1. GAF Modified Bitumen Roof Systems shall be installed in accordance with GAF published installation instructions, subject to the Limitations / Conditions of Use noted below. 2. System attachment requirements for wind load resistance are set forth in Appendix 1. Limitations / Conditions of Use: 1. This Evaluation Report is not for use within the HVHZ. 2. Refer to a current Approved Roofing Materials Directory for surfacing requirements and fire rating. 3. For steel deck installations, foam plastic insulation shall be separated from the building interior in accordance with FBC Section 2603.4 unless the exceptions stated in FBC Sections 2603.4.1 and 2603.8 apply. 3. Unless otherwise noted in Appendix 1, roof decking and its attachment shall be specified and installed to meet project design criteria to the satisfaction of the AHJ. 4. For recover installations, the existing roof shall be examined in accordance with FBC Section 1510. 5. For mechanically attached components, the maximum design pressure for the selected assembly shall meet or exceed the Zone 1 design pressure determined in accordance with FBC Chapter 16. Zones 2 and 3 shall employ a tighter component attachment density designed by a qualified design professional to resist the elevated pressure criteria. Commonly used methods are RAS 117 and FM LPDS 1-29. 6. For adhered insulation, the maximum design pressure for the selected assembly shall meet or exceed critical design pressure determined in accordance with FBC Chapter 16. No rational analysis is permitted for these systems. 7. For mechanically attached com ponents over existing roof decks, fasteners shall be tested in the existing deck for withdrawal resistance. A qualified design professional shall review the data for comparison to the minimum requirements for the system. Testing and analysis shall be in accordance with TAS 105. 8. For adhered insulation over existing substrates, the existing deck or roof surface shall be examined for compatibility with the membrane or insulation adhesive to be installed. If any surface conditions exist that bring system performance into question, field uplift testing in accordance with ASTM E907 or FM LPDS 1-52 shall be conducted on mock-ups of the proposed new roof assembly. 9. For recover installations, the existing roof system shall be capable of resisting project design pressures on its own merit to the satisfaction of the AHJ, as documented through field uplift testing in accordance with ASTM E907 or FM LPDS 1-52.
