The following assessment criteria is 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. The following is our assessment summary. The dwelling is timber framed of newer construction age with an "A" framed roof, and 5' — 0" main attic/roof height, built from nominal 2" x 6" dimensional lumber joists at 16" o/c, typical. Materials are assumed to be minimum Hem-Fir #2 grade, or better, with standard construction components. There are widely spaced 1" x 6" collar ties installed in the main roof/attic's full. length, in panel installations areas, to minimally reinforce the roof joists, 18" +/-below the top of the 2" x 8" ridge beam. There are no other vertical supports for the roof joists or ridge beam to framing below to reinforce the roof joists. The attic is not finished, and roof framing was mostly accessible at inspection time, so a complete assessment and confirmation of framing spacing, sizes and condition was able to be performed in the main 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 for the analysis and design of any proposed improvements to stiffen the roof framing members. 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. 2. Given the dwelling's roof structure construction and condition, we have concluded that the existing roof joists' load carrying capacity should be able to sustain the additional dead and redistributed live loads from the new solar panels if installed Mr. Scott Leduc December 5, 2012 Page 2 correctly. The dwelling's roof members will be able to also redistribute the snow live loads, and additional dead load from the solar panels to the adjacent framing members. These additional loads should not produce stresses beyond the allowable stress range for these roof framing members assumed as Hem-Fir#2 materials. Considering the lower roof slopes, array sizes; roof joists' size, spacing, condition, and minimal collar ties, the panel supports shall be placed at and attached to no more than every second joist as panels are installed across joists. No panel support spacing shall be greater than two (2) roof joist spaces, or 32"o/a, as specified in framing- support Layout#1 submitted for our review. No revisions are required. This layout can be used for permit submittals and given to installers for their use. All panels shall be installed as shown on the layout plans, with 32" o/c max. support spacing, or two joist spaces, as shown in Layout#1, and stated above for the roof sections. Framing member sizes, spacing and condition must be properly verified by Vivint's installers, by non-destructive means, prior to any installations. Send any differing information to this engineer for review and approval, prior to continuing with installations. 3. This assessment meets current Massachusetts Building Code, 8d'Edition—Residential —Amendments to International Residential Code, (IRC), 2009 Edition, for one and two family dwellings. B. SOLAR PANEL ATTACHMENT TO ROOF STRUCTURE: 1. 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 shall make the dwelling's owners aware that long term build-up of heavy snow accumulations in the event of extreme snowfall conditions, may produce some deflections in the roof. These deflections should be temporary in nature and will not affect the structural integrity of the roof. The solar panels do not need to be cleared of such accumulated snow. 3. If at installation time,technicians are able to add more roof panels than originally designed, it is generally acceptable to add up to six(6) more panels, without revised plans and permit resubmittals. This is acceptable if the panels are installed to the same support spacing criteria called for above. Vivint shall notify this engineer if more than six(6) additional panels are being installed, prior to installations. As-built layout plans shall be submitted to same for more than six (6) additional panels. C. WIND UPLIFT LOAD: Mr. Scott Leduc December 5, 2012 Page 3 1. Refer to attached ZEP calculation sheet for ASCEISEI 7-10 Minimum Design Loads For Buildings and Other Structures; wind speed this location of 120 miles per hour for Exposure Category `B", and 22 degree roof slopes on the dwelling 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 120 mph, uplift is shown. 2. Total area subject to wind uplift is calculated for the Interior,Edge and Comer 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 ''/z"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: 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. These values are within acceptable limits of recognized industry standards for similar structures. The roof members should 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 p ses.
