The roofing,decking,and roof trusses are in good condition.The existing structure will be <br /> adequate for supporting the additional PV dead load and wind loads. <br /> The securement method of the PV system is to be flush mounted to the asphalt shingle roof with the <br /> Quickmount Q-rail Light railing and the Sunmodo Nano Mounts.The attachments can be attached <br /> up to 48"apart.The mounts should be staggered,where possible,to allow distribution of the design <br /> loads evenly to the structure.The mounts shall be installed with a min.5/16"lag screw with <br /> minimum 2-5/16"thread length. <br /> Please see attached documents and contact me should you have any questions. <br /> Sincerely, <br /> D.Chad Godwin,PE 81360 \ ��1111I1►I//�,, <br /> Exp. 02/28/2021 \���\'- lE C. <br /> 81 Z <br /> d 1 O 1 <br /> 1 1 � <br /> �0� SPAT OF <br /> 0 N. <br /> �` <br /> ,,,,� ///i <br />
