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. This unique feature ensures greater security during extreme weather and a longer system lifetime.Compatible with Flat & Pitched RoofsRoof Mount utilizes XR Rails, along with optional all-in-one attachments, WRVHFXUHV\VWHPVÁXVKagainst residential roofs.Roof Mount utilizes XRRails, along with optionalall-in-one attachments,WRVHFXUHV\VWHPVÁXVKagainst residential roofs.Corrosion-Resistant MaterialsXR Rails are compatible with FlashFoot and other pitched roof attachments.IronRidge offers a range of tilt leg RSWLRQVIRUÁDWroof mounting applications.All XR Rails are made of 6000-series aluminum alloy, then protected with an DQRGL]HGÀQLVK$QRGL]LQJSUHYHQWVVXUIDFHand structural corrosion, while also providing a more attractive appearance.

Pierce, FL 34982 Re: Desroches – Residential PV Roof Mount Installation 248 Camino Del Rio 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. The existing roof covering is Asphalt Shingle with min. ½” 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 the Sunmodo Nano Mounts. The attachments can be attached up to 48” apart in roof zone 1, and 24” apart in roof zones 2e, 2r, & 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. Please see attached documents and contact me should you have any questions. Sincerely, D.
