Matthew Walsh, SE, PE Samuel Brown, PE Senior Structural Engineering Manager Structural Engineer james.walsh@a vivin Molar.com sam.brown0vivintsolar.com January 10, 2019 Re: Structural Engineering Services Kagan Residence 9 Barnes Cir, Salem, MA S-6037425; MA-01 To Whom It May Concern: We have reviewed the following information regarding solar panel installation on the roof of the above referenced home: 1. Site Visit by a representative from our office under my supervision identifying specific interior and exterior site information including the condition of the existing roof system and the size, spacing, and condition of existing structural framing members. Information gathered during the site visit includes photographs, sketches, and verification forms. 2. Design drawings of the proposed PV System layout, including details to mount the new solar panels to the existing roof. Based on the above information, we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation: A. Description of Residence: The existing residence is typical wood framing construction with a maximum of two layers of composite shingle roofing. All wood material utilized for the roof system is assumed to be Spruce-Pine-Fir#2 or better with standard construction components and consists of the following: • Roof Section 1: Prefabricated trusses at 24" on center. Survey photos indicate that there was free access to verify the framing size and spacing. B. Loading Criteria 8.49 PSF= Dead Load (roofing/framing) 2.59 PSF= Dead Load (solar panels/mounting hardware) 11.08 PSF=Total Dead Load 20 PSF= Roof Live Load 50 PSF =Ground Snow Load (based on local requirements) Wind speed of 127 mph (based on Exposure Category B-the total area subject to wind uplift is calculated for the Interior, Edge, and Corner Zones of the dwelling.) C. Solar Panel Anchorage 1. Installation shall proceed in accordance with the applicable guidelines and recommendations indicated below. If, during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified before proceeding with the installation. • Unirac, Inc. Installation Manual, which can be found on the Unirac, Inc.website (www.unirac.com). 2. The solar panels are 11/2' thick and mounted 41/2" off the roof for a total height off the existing roof of 6". At no time will the panels be mounted higher than 6"above the existing plane of the roof. Page l of 2 v solar Page 2 of 2 3. The following mounting types shall be used. Please refer to the mounting details for the associated required penetration depth. Based on our evaluation, the pullout demand is less than the maximum allowable per connection and therefore is adequate. • Unirac, Inc.: (1) 5/16" lag screw. Pullout capacity based on National Design Specifications (NDS) of timber construction specifications for Spruce-Pine-Fir is 235 Ibs/inch penetration. 4. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph B above, using the wind load uplift procedures of ASCE 7-10 and is specified below. These spacing requirements apply to all mount types indicated above. The following values have been verified by in-house testing and the mounting hardware manufacturers'data, which are available upon request. Panel support connections should be staggered, where possible, to distribute load to adjacent members. Modules in Landscape Modules in Portrait Roof Zone Interior Ede Corner Interior Ede Corner Max Vertical Spacing in 40 40 40 66 66 66 Max Horizontal Spacing in 72 72 72 48 48 48 Max Uplift Load Ibs 174 141 133 293 239 224 D.Summary Based on the above evaluation,with appropriate panel anchors being utilized the roof system designed on will adequately support the additional loading imposed by the solar panels, if installed correctly. This evaluation has been performed for the structural elements only and verifies that they are in conformance with the 2015 International Residential Code with Massachusetts Amendments, current industry standards and practice, and the information supplied to us at the time of this report. If there are any questions regarding'the above, or if more information is required, please contact me. i N OF M,gss�� Regards, \se J. J.
