Pierce, FL 34982 Re: Kassa- Residential PV Roof Mount Installation 2840 Eagles Nest Way Port Saint 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: 2017 Florida Building Code 6th Edition, FBC ASCE 7 Min. Design Loads for Buildings &Other Structures Per 2017 FBC,the Roof Mounted PV system will be subject to the following design criteria: Design Wind Speed(V it) - 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. The existing roof covering is Asphalt Shingle with min. 1/z"plywood decking and 2"x 4" roof trusses 24" 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 asphalt shingle roof with the Ironridge railing and flashings/attachments.The attachments can be attached up to 48"apart in roof zone 1, 24" apart in roof zone 2,and no mounts in roof zone 3.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.
