Snow load used in the span tables is the ground snow and shall conform to ASCE 7-16 Fig. 7.2-1 and applicable state & local county/city am endments to the IBC. If the local jurisdiction specified snow load is in the format of a flat roof snow, it shall first be converted to a ground snow following the local building code/amendment before the application of the attached span table. No special snow conditions are considered including unbalanced, drifting, sliding, retention, or ponding snow. No rain-on-snow surcharge load is considered. The span tables do not apply to buildings which are intentionally kept below freezing, kept just above freezing, or unheated. 4. T he span tables reflect the ASCE 7 prescribed earthquake loads with the m axim um magnitudes being: (a) For ground snow no greater than 42psf: S s ≤ 2.0g for Site Class A, B, C, D. (b) For ground snow greater than 65psf: S s ≤ 1.0g for Site Class A, B, C, D. (c) For ground snow between 42 and 65psf: S s ≤ 1.5g for Site Class A, B, C, D. 5. Roof zones are defined by ASCE 7-16 Figure 30.3-2A to Figure 30.3-2I and are organized into three groups in which the zones share the same External Pressure Coefficients (GCp). Roof zones comprising each group along with each roof zone’s size and location are depicted in Figures 2 and 3 below each span table. 6. Allowable span length in the charts m ay be m ultiplied by a factor of 1.08 if the rails are continuous over a m inim um of three spans. 7.

CO Flush Mount System Certification Letter - 3 28357 Industrial Blvd. Hayward, CA 94545 1-800-227-9523 IronRidge.com Tabulated span values provided in this letter must be adjusted under the following scenarios: 1. Exposed Module conditions: A module is defined as Exposed (per Section 29.4.4 of ASCE 7-16) if the distance from any of its free edges (an edge with no connectivity to other modules) to its facing roof edge (such as eave, ridge, rake, or hip) is greater than 0.5h (h is ASCE defined building height) AND if the distance from its free edge to any other adjacent array or panel is greater than 4 ft. The allowable spans and cantilever of rails within Exposed Module areas shall be adjusted according to the following rules: (a) For a project site with wind speed less than or equal to 140 mph, the adjusted allowable span shall be determined by using an increased wind speed (Equivalent Wind Speed) from the attached span tables with no changes to other design parameters. The Equivalent Wind Speed for Exposed Modules is shown in Table 1 below.

Edge Module conditions: A module is defined as an Edge Module when its distance to a perimeter roof edge (such as eave, ridge, rake, or hip) is less than 2h2 (h2 = offset distance from the module top surface to the roof surface). The allowable spans and cantilever of rails within Edge Module areas shall be adjusted according to the following rules: (a) The span adjustment shall only be applied to the rails directly under the modules which are in contact with the perimeter 2h2 areas along the roof edge. Additionally, if the roof edge is the eave or ridge, only the rails nearest to that roof edge shall be considered for span adjustment. (b) For a project site with the wind speed not exceeding 130 mph, the adjusted allowable span shall be determined by using an increased wind speed (Equivalent Wind Speed) onto the attached span tables while other design parameters remain the same. The Equivalent Wind Speed is tabulated below.

NO.SIZE SCALE: NTS EX-0015 REVIEWED BY SAFEBUILT 06/20/2022 Tech Brief The Strongest Attachment in Solar IronRidge FlashFoot2 raises the bar in solar roof protection. The unique water seal design is both elevated and encapsulated, delivering redundant layers of protection against water intrusion. In addition, the twist-on Cap perfectly aligns the rail attachment with the lag bolt to maximize mechanical strength. FlashFoot2 Twist-On Cap FlashFoot2’s unique Cap design encapsulates the lag bolt and locks into place with a simple twist. The Cap helps FlashFoot2 deliver superior structural strength, by aligning the rail and lag bolt in a concentric load path. Single Socket Size A custom-design lag bolt allows you to install FlashFoot2 with the same 7/16” socket size used on other Flush Mount System components. Three-Tier Water Seal FlashFoot2’s seal architecture utilizes three layers of protection. An elevated platform diverts water away, while a stack of rugged components raises the seal an entire inch. The seal is then fully-encapuslated by the Cap. FlashFoot2 is the first solar attachment to pass the TAS-100 Wind-Driven Rain Test. Water-Shedding Design An elevated platform diverts water away from the water seal. REVIEWED BY SAFEBUILT 06/20/2022 © 2016 IronRidge, Inc. All rights reserved.

Version 1.0 Tech Brief Installation Features Testing & Certification Structural Certification Designed and Certified for Compliance with the International Building Code & ASCE/SEI-7. Water Seal Ratings Water Sealing Tested to UL 441 Section 27 “Rain Test” and TAS 100-95 “Wind Driven Rain Test” by Intertek. Ratings applicable for composition shingle roofs having slopes between 2:12 and 12:12. UL 2703 Conforms to UL 2703 Mechanical and Bonding Requirements. See Flush Mount Install Manual for full ratings. Alignment Markers Quickly align the flashing with chalk lines to find pilot holes. Rounded Corners Makes it easier to handle and insert under the roof shingles. Reinforcement Ribs Help to stiffen the flashing and prevent any bending or crinkling during installation. A B C E B C Benefits of Concentric Loading Traditional solar attachments have a horizontal offset between the rail and lag bolt, which introduces leverage on the lag bolt and decreases uplift capacity. FlashFoot2 is the only product to align the rail and lag bolt. This concentric loading design results in a stronger attachment for the system.
