Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation. Design Parameters Code: 2020 Minnesota Building Code (2018 IBC) Risk Category: II Design wind speed: 109 mph (3-sec gust) per ASCE 7-16 Wind exposure category: C Ground snow load, Pg: 50 psf Existing Roof Structure Roof structure: 2x4 manufactured trusses @ 24" O.C. Roofing material: composite shingles Roof slope: 26° Connection to Roof Mounting connection: (1) 5/16" lag screw w/ min. 2.5" threaded embedment into framing at max. 48" o.c. along rails (2) rails per row of panels, evenly spaced; panel length perpendicular to the rails not to exceed 68 in. Rail cantilever shall not exceed 50% of connection spacing. Conclusions Based upon our review,we conclude that the existing structure is adequate to support the proposed solar panel installation. The gravity loads,and thus the stresses of the structural elements,in the area of the solar array are either decreased or increased by no more than 5%.Therefore,the requirements of Section 806.2 of the 2020 Minnesota Conservation Code for Existing Buildings are met and the structure is permitted to remain unaltered. 651 W. Galena Park Blvd., Ste. 101 / Draper, UT 84020 / T (801) 990-1775 / F (801) 990-1776 / www.vectorse.com VSE Project Number: U1991.0723.211 Darren House Residence 4/12/2021 The solar array will be flush-mounted (no more than 10"above the roof surface)and parallel to the roof surface.Thus,we conclude that any additional wind loading on the structure related to the addition of the proposed solar array is negligible. The attached calculations verify the capacity of the connections of the solar array to the existing roof against wind (uplift), the governing load case.Because the increase in lateral forces is less than 10%,this addition meets the requirements of the exception in Section 806.3 of the 2020 Minnesota Conservation Code for Existing Buildings.Thus the existing lateral force resisting system is permitted to remain unaltered. Limitations Installation of the solar panels must be performed in accordance with manufacturer recommendations.All work performed must be in accordance with accepted industry-wide methods and applicable safety standards.The contractor must notify Vector Structural Engineering,LLC should any damage,deterioration or discrepancies between the as-built condition of the structure and the condition described in this letter be found.Connections to existing roof framing must be staggered,except at array ends,so as not to overload any existing structural member.The use of solar panel support span tables provided by others is allowed only where the building type,site conditions,site-specific design parameters,and solar panel configuration match the description of the span tables.The design of the solar panel racking (mounts,rails,etc.)and electrical engineering is the responsibility of others.Waterproofing around the roof penetrations is the responsibility of others.Vector Structural Engineering assumes no responsibility for improper installation of the solar array.

Ultra Rail features two rail proﬁ les; UR-40 is a lightweight rail proﬁ le that is suitable for most geographic regions and maintains all the great features of SnapNrack rail, while UR-60 is a heavier duty rail proﬁ le that provides a larger rail channel and increased span capabilities. Both are compatible with all existing mounts, module clamps, and accessories for ease of install. The Entire System is a Snap to Install • New Ultra Rail Mounts include snap-in brackets for attaching rail • Compatible with all the SnapNrack Mid Clamps and End Clamps customers love • Universal End Clamps and snap-in End Caps provide a clean look to the array edge Heavy Duty UR-60 Rail • UR-60 rail proﬁ le provides increased span capabilities for high wind speeds and snow loads • Taller, stronger rail proﬁ le includes proﬁ le- speciﬁ c rail splice and end cap • All existing mounts, module clamps, and accessories are retained for the same great install experience SnapNrack Umbrella Sealing Technology • Innovative Flashing Elevates Protection. New ﬂ ashing uses a fully formed raised cone to prevent any potential water from getting into penetration. Feel secure as the ﬂ ashing is one piece and doesn’t rely on multiple parts sealing together. • Mechanical Design Creates a Lifelong Seal. Patented Umbrella technology utilizes unique Umbrella Washer to seal lag bolt, L Foot, and ﬂ ashing and prevent any potential roof leaks. Technology passes UL 2582 Wind Driven Rain Test without a rubber seal, however rubber gasket is included for extra peace of mind. • Single Fastener Eliminates Extra Steps. Utilize one lag bolt with Umbrella Washer to secure the entire mount assembly and ﬂ ashing. No longer necessary to attach a base, then a ﬂ ashing, then a mount as all are secured in one step. • Single Tool Installation. SnapNrack was the ﬁ rst in the industry to develop a complete system that only requires a single tool. That tradition is continued as a ½” socket is still the only tool necessary to secure the mount as well as all other parts of the system. snapnrack.com Featuring New Innovative Flashing Smaller 9”x12” size allows for easier insertion under shingles Alignment markers make it easy to locate pilot holes Rounded corners make for easier insertion & eliminate corner points from folding up Note: Flashing shown in yellow for illustration purposes only. © 2018 by SnapNrack Solar Mounting Solutions.
