C. Required Structural Repairs <br /> The analysis performed has indicated that the existing roof will require the following repairs prior to installation of <br /> the photovoltaic array: <br /> Hip/Cross-Slope Framing - The mounting hardware is not designed to support the array with the roof framing <br /> running horizontally (cross-slope). At locations where mounting hardware will be installed, install blocks between <br /> existing framing members in accordance with detail SK-7. <br /> D. Solar Panel Anchorage <br /> 1. Installation shall proceed in accordance with the applicable guidelines and recommendations indicated below. <br /> If, during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office <br /> should be notified before proceeding with the installation. <br /> • SnapNrack Installation Manual, which can be found on the SnapNrack website (https://snapnrack.com/). <br /> 2. The solar panels are 1%' thick. At no. time will the panels be mounted higher than 10" above the existing <br /> surface of the roof. <br /> 3. The following mounting types shall be used. Please refer to the mounting details for the associated mounting <br /> method requirements. Based on our evaluation, the uplift demand is less than the maximum allowable per <br /> mount and therefore is adequate. <br /> • RL-U SpeedSeal: (1) 5/16" lag screw. Pullout capacity based on National Design Specifications (NDS) <br /> of timber construction specifications for Southern Pine is 235 Ibs/inch penetration. I <br /> 4. Fasteners are installed to meet industry standards and this document satisfies requirements in 2017 FBC <br /> 2303.4.5 verifying that the fasteners will not adversely affect the roof framing. <br /> 5. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph B above, using the <br /> wind load uplift procedures of ASCE 7-10. These spacing requirements apply to all mount types indicated <br /> above. The following values have been verified by in-house testing and the mounting hardware manufacturers' <br /> data, which are available upon request. Panel support connections should be staggered, where possible, to <br /> distribute load to adjacent members. <br /> Modules in Landscape Modules in Portrait <br /> Roof Zone Interior Ede Corner Interior Ede Corner <br /> Max Vertical Spacing in 40 40 40 66 66 66 <br /> Max Horizontal Spacing in 48 48 48 37 35 37 <br /> Cantilever in 16 16 16 12 12 12 <br /> E. Summary <br /> Based on the above evaluation, with the structural repairs completed as prescribed and appropriate panel anchors <br /> being utilized, the roof system designed on will adequately support the additional loading imposed by the solar <br /> panels, if installed correctly. This evaluation has been performed for the structural elements only and verifies that <br /> they are in conformance with the 2017 Florida Building Code-Residential 6th Edition, current industry standards <br /> and practice, and the information supplied to us at the time of this report. <br /> vivint®S®lare <br /> Page 2of8 A SUflfl n COMPANY <br />
