From the field observation report, the roof is made of Flat Rolled <br />Composition shingle roofing over roof plywood supported by 2X8 Rafters at 16 inches. The slope of the roof <br />was approximated to be 3 degrees. <br />After review and based on our structural capacity calculation, the existing roof framing has been determined to <br />be adequate to support the imposed loads without structural upgrades. <br /> I certify that the PV module assembly including all attachments supporting it have been reviewed to be in <br />accordance with manufacturer's specifications. Capacity Calculations were done in accordance with applicable <br />building codes. <br />Design Criteria <br />projects@evengineersnet.com <br />http://www.evengineersnet.com <br />1414 S Shelton St <br />12/2/2024
