Signed 03/26/2026 <br />EV Engineering, LLC <br />projects@evengineersnet.com <br />http://www.evengineersnet.com <br />Exp: 06/30/2026 <br />This Letter is for the existing roof framing which supports the new PV modules as well as the attachment of the PV <br />system to existing roof framing. From the field observation report, the roof is made of Tile roofing over roof <br />plywood supported by 2X6 Rafters at 24 inches. The slope of the roof was approximated to be 18 degrees. <br />After review of the field observation data and based on our structural capacity calculation, the existing roof <br />framing has been determined to be adequate to support the imposed loads without structural upgrades. <br />Contractor shall verify that existing framing is consistent with the described above before install. Should they find <br />any discrepancies, a written approval from SEOR is mandatory before proceeding with install. Capacity <br />calculations were done in accordance with applicable building codes. <br />projects@evengineersnet.com <br />http://www.evengineersnet.com
