Tech BriefSolar Is Not Always SunnyOver their lifetime, solar panels experience countless extreme weather events. Not just the worst storms in years, but the worst storms in 40 years. High winds capable of ripping panels from a roof, and snowfalls weighing enough to buckle a panel frame. XR Rails are the structural backbone preventing these results. They resist uplift, protect DJDLQVWEXFNOLQJDQGVDIHO\DQGHIÀFLHQWO\transfer loads into the building structure. Their superior spanning capability requires fewer roof attachments, reducing the number of roof penetrations and the amount of installation time.XR Rail FamilyForce-Stabilizing CurveSloped roofs generate both vertical and lateral forces on mounting rails which can cause them to bend and twist. The curved shape of XR Rails is specially designed to increase strength in both directions while resisting the twisting.

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. Chad Godwin, PE 81360
