A,P_'t IRON RIDGE XR Rail Family
Solar Is Not Always Sunny
Over 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
against buckling and safely and efficiently
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. y

Re: Hanson- Residential PV Roof Mount Installation
1508 Coralbean Ct.
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:
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.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.
Please see attached documents and contact me should you have any questions.
Sincerely,
D. Chad Godwin, PE 81360
