Site Visit/Verification Form prepared by a Vivint Solar representative identifying specific site information including size and spacing of rafters for the existing roof structure. 2. Design drawings of the proposed system including a site plan, roof plan and connection details for the solar panels. This information was prepared by Vivint Solar and will be utilized for approval and construction of the proposed system. 3. Photovoltaic Rooftop Solar System Permit Submittal prepared by Vivint Solar identifying design parameters for the solar system. 4. Photographs of the interior and exterior of the roof system identifying existing structural members and their conditions. 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: Description of Residence: The existing residence is typical wood framing construction with the roof system consisting of 2 x 6 dimensional lumber at 16" on center with 1 x 10 collar ties every 64". The attic space is unfinished and photos indicate that there was free access to visually inspect the size and condition of the roof rafters. All wood material utilized for the roof system is assumed to be Spruce-Pine-Fir #2 or better with standard construction components. Our review of the photos of the exterior roof does not indicate any signs of settlement or misalignment caused by overstressed underlying members. Stability Evaluation: A. Wind Uplift Loading 1. Refer to attached ZEP calculations sheet for ASCE/SEI 7-10 Minimum Design Loads for Buildings and other Structures, wind speed of 100 mph based on Exposure Category "B" and 25 and 23 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure "B", Zone 2 per(ASCE/SEI 7-10). 2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the dwelling. '} Page 2 of 2, B., Loading Criteria • 10 PSF= Dead Load roofing/framing 40 PSF=Live Load (ground snow load) • 5 PSF= Dead Load solar panels/mounting hardware Total Dead Load=15 PSF The above values are within acceptable limits of recognized industry standards for similar structures. Analysis performed of the existing roof structure utilizing the above loading criteria indicates that the existing rafters will support the additional panel loading without damage, if installed correctly. C. Roof Structure Capacity 1. The photographs provided of the attic space and roof rafters show that the framing is in good condition with no visible signs of damage caused by prior overstressing. 2. The dwelling owners shall be made aware that long term build-up of heavy snow conditions may produce deflections in the roof. If any deflection is noticed, then it is recommended that the solar panels be cleared of accumulated snow more than one (1) foot deep over a period of one week. If no deflections are visible under any snow loading over a period of time, then there is no need to clear the solar panels. D. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent "ZEP Code Compliant Installation Manual', which can be found on the ZEP website (zepsolar.com). If during solar panel installation, the roof framing members appear unstable, deteriorated, structurally compromised or deflect non-uniformly, our office should be notified before proceeding with the installation. 2. Maximum allowable pullout per lag screw is 235 Ibs/inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications for Hem-Fir(North Lumber) assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 %', is less than what is allowable per connection and therefore is adequate. Based on the variable factors for the existing roof framing and installation tolerances, using a thread depth of 2 W with a minimum size of 5/16" lag screw per attachment point for panel anchor mounts should be adequate with a sufficient factor of safety. 3. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be placed at and attached to no greater than every fourth roof rafter as panels are installed perpendicular across rafters and no greater than the panel length when installed parallel to the rafters (portrait). No panel supports spacing shall be greater than four(4) rafter spaces or 64"o/c, whichever is less. 4. Panel supports connections shall be staggered to distribute load to adjacent rafters. Based on the above evaluation, it is the opinion of this office that with appropriate panel anchors being utilized the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is based on information supplied to us at the time of this report and current industry standards and practices. Should you have any questions regarding the above or if you require further information do not hesitate to contact me.

The assessment criteria are based upon Vivint's recent dwelling site visit including roof framing photographs and field notes. We have also reviewed Vivint's PV Solar Permit Submittal, calculations, installation layouts and notes,PV 1.0 "Site Plan",PV 2.0 "Roof Plan", and PV 3.0, "Mounting Details". All were supplied for information on the proposed solar panels installation on the dwelling's roof framing members for our assessment summary. The dwelling is timber framed of older construction age with an "A" framed main roof, 12'- 6" +/- high (estim.), assumed ttoTbe built from nominal 2" x 6" or 2" x 8" dimensional lumber joists at 16" to 20" o/c, typic0 110 ;mac wellings. The maximum roof joist span length is 17' — 0" +/- excluding reduction 14or mid-span supports. Two layers of roof shingles are assumed. Materials are assumed ass minimum Hem-Fir #2 grade, conservatively (low allowable stresses), with standard construction components (better grade lumber may have been used). No collar ties could be confirmed as installed below the ridge beam in the main "A" roofs'/attic's full length, in panel installations areas, due to the finished upper floor/attic. However the flat ceilings are typically framed with newer or original collars ties attached to roof joists at each end for reinforcing. There are no other roof joists or ridge beam supports, however the partial height sidewalls of the second floor rooms will act as mid-span joist supports. The main attic and roof framing were not accessible by access panels or crawl spaces at the site inspection and evaluation, therefore a partial assessment and confirmation of framing spacing, sizes and condition was able to be performed for this roof. No architectural drawings were available at the time of this report preparation. Refer to plans and documents prepared by Vivint for dwelling dimensions, locations and sizes of solar panel units. The roof framing members were reviewed and checked for their capacity of new loadings. A. CAPACITY OF EXISTING ROOF TO SUPPORT PROPOSED SOLAR PANELS: 1. Our assessment included using the proposed solar panels dead load that were given to us in the ZEP calculation sheets and the live and dead loads described below. Our review of the roof information shows that there are no visible undulations or unevenness, indicating that the roof framing members are not visibly overstressed or weakened by past heavy snow loads. Mr. Paul Greene March 7, 2014 Page 2 2. Given the dwelling's roof construction and condition, the existing roof joists' load carrying capacity will be able to carry the added dead and redistributed live loads from the new solar panels if installed correctly. The dwelling's roof members will also redistribute the snow live loads, and additional solar panels dead load to the adjacent framing members. These additional loads should not produce stresses beyond the allowable stress range for roof framing members assumed as Hem-Fir 92 materials. Considering the high roof slopes, array sizes/locations; lack of access to confirm roof joists' size, spacing, condition; and collar ties, the panel supports shall be set/ attached to every second to third joist for lateral installations over joists. No Panel supports acin shall be rg eater than two (2)to three(3)roof joist spaces or 48" o/c whichever is less, to be shown in the PV 2.0 Roof Layout plan(s). Note—Layout Array Drawing#1 submitted for review, shows every three joists, 24" o/c joists, 72" o/c maximum panel support spacing, and which needs to be revised to the above spacing. The panel supports shall be installed in a staggered pattern,to ensure proper load distribution,with no more than three supports placed on any single joist except at ends of layouts. After revising, this layout can be used for permit submittals and installations. All panels shall be installed as shown on the layout plans, with 48"o/c maximum support spacing, or two to three joist spaces (w i.l and staggered to be shown in the final revised PV 2.0 Roof Layout plan(s), as stated above. Framing member sizes, spacing and condition must be properly verified by Vivint's installers, prior to any installations. Send any differing information to this engineer for review and approval, prior to continuing with any installations. 3. This assessment meets current Massachusetts Building Code, 8u Edition—Residential —Amendments to International Residential Code, (IRC), 2009 Edition, for one and two family dwellings. B. SOLAR PANEL ATTACHMENT TO ROOF STRUCTURE: I. The solar panels shall be mounted in accordance with the latest"ZEP Company's Code Compliant Installation Manual" found on the ZEP website and not included herein. No additional reinforcing requirements are required for these installations. However, if during solar panel installations,the roof framing members feel unstable, or show interior or exterior evidence of minor or excessive movement,then this engineer should be notified as soon as possible prior to proceeding with installations. 2. Vivint should notify the homeowners that long term build-up of accumulated snow in the event of extreme snowfall conditions, may produce some roof deflections. These deflections will be temporary in nature and will not affect the roofs structural integrity. The solar panels do not need to be cleared of such accumulated snow. C. WIND UPLIFT LOAD: 1. Refer to attached ZEP calculation sheet for ASCEISEI 7-10 Minimum Design Loads Mr. Paul Greene March 7, 2014 Page 3 For Buildings and Other Structures, for wind speed at this location of 100 miles per hour* for Exposure Category`B", and 32 degree roof slopes on the dwelling's roof areas. Ground snow load is 40 p.s.f.* for Exposure `B", Zone 1 (per ASCEISEI 7- 10) of the roof s interior portion, and effective wind speed of 100 mph*, uplift is shown. 2. Total area subject to wind uplift is calculated for the Interior,Edge and Corner Zones. A maximum and user selected support(foot) spacing is shown for each location zone. D. PANEL ANCHORAGES: 1. Maximum allowable pullout per lag screw= 235 #/inch from National Design Standards (NDS)timber construction specifications for Hem-Fir-North lumber (assumed). Using 4 lag screws, the pullout value is less than 235 #/inch of screw thread and OK. Considering the variable factors for the existing roof framing members, and installation tolerances, use a 2 1/2"threaded depth with a minimum 5/16" lag screw per attachment points in roof joists ("rafters")components for panel anchor mounts. This should give a sufficient factor of safety. E. LIVE,DEAD AND SNOW LOADS: 1. Live load=40 p.s.f. ground snow load; 10 p.s.f. attic storage (trusses only) Dead Load= 10 p.s.f.-roofing/framing; 5 p.s.f. -panels, mounting hardware Total Live Load=40 p.s.f; Total Dead Load= 15 p.s.f. 2. These values are within acceptable limits of recognized industry standards for similar structures. The roof members will be able to sustain the solar panel attachments without damage, if installed in a workmanship like manner according to the above criteria. We have based our structural capacity determination on applicable building codes, professional engineering inspection and design experience, opinions and judgments. This report covers this dwelling's assessment for only the areas for solar panel installations that were made according to generally recognized structural analysis standards and procedures. The normal structural engineering industry standard of care utilized for this type of work was used during this report preparation. The assessments and recommendations in this report were reviewed to ensure a proper level of quality and uniformity. This report adheres to accepted State and National practices for current building code standards and can be used for construction purposes.
