Pierce, FL 34982 Re: Flores - Residential PV Roof Mount Installation 110 Beach Ave Port St. Lucie, FL 34952 Plan Reviewer, This letter is regarding the installation of a new roof mounted Solar PV System on the existing residential structure at the address above. I have reviewed the attachment plan and have determined that the roof mounted PV system is in compliance with the applicable sections of the following Codes as amended and adopted by the jurisdiction: 2020 Florida Building Code 7th Edition, FBC ASCE 7 Min. Design Loads for Buildings & Other Structures Per 2020 FBC, the Roof Mounted PV system will be subject to the following design criteria: Design Wind Speed(Vult) - 160mph 3sec gust, Exposure Category – C The PV System consist of the modules, railing, and connection hardware. The system will add a dead load of approximately 3 psf to the roof. There are two existing roof coverings; one is shingle with min. ½” plywood decking and 2” x 4” roof trusses 24” O.C. The other is flat roof with EPDM over min. ½” plywood decking and 2” x 6” roof trusses 16” O.C. The roofing, decking, and roof trusses are in good condition. The existing structure will be adequate for supporting the additional PV dead load and wind loads. The securement method of the PV system is to be flush mounted to the roofs with the Ironridge railing and flashings/attachments. The attachments for the shingle roof can be attached up to 48” apart in roof zones 1, 2e, and 24” apart in roof zones 2n, 2r, 3e, & 3r. The mounts should be staggered, where possible, to allow distribution of the design loads evenly to the structure. The mounts shall be installed with a min. 5/16” lag screw with minimum 2-5/16” thread length directly to roof truss. The flat roof attachments for the EPDM roof can be attached up to 48” apart in all roof zones. The mounts should be staggered, where possible, to allow distribution of the design loads evenly to the structure. The mounts shall be installed with (8) XHD #15 screws. Please see attached documents and contact me should you have any questions. Sincerely, D.
