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 and expanded rear roof(not getting panels), I I' +/- high (estim.), assumed to be built from nominal 2" x 6" dimensional lumber joists at 16" to 19" o/c,typical. The maximum roof joists span length is 18% 6" +/-, excluding reductions for mid-span supports. Materials are assumed as minimum Hem-Fir #2 grade, conservatively (low allowable stresses), with standard construction components (better grade lumber may have been used). Two layers of roof shingles are assumed. Collar ties were not confirmed to be installed below the ridge beam in the main"A"roofs'/attic, in panel installations areas, due to the finished upper floor/attic. However, the flat ceiling joists are typically framed with original or newer collar ties attached at each end to roof joists for reinforcing. The partial height interior room side walls will also act as mid-span roof joists supports. The main attic/roof framing were only partially accessible by crawl spaces and access panels at the site inspection/ evaluation, so only a partial assessment and confirmation of framing spacing, sizes and condition was able to be performed for these roofs. 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 November 23, 2013 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#2 materials. Considering the high roof slopes, array sizes; lack of complete 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 support spacing shall be more 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 #1submitted for review, shows this maximum panel support spacing. The panel supports shall be installed in staggered patterns to ensure the roper load distribution, and with no more than three supports placed on any single joist, except at ends of layouts. This layout can be used for permit submittals and installations,with the staggering of supports being done in the field. 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, 8s'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 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 roof s 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 ASCE/SEI 7-10 Minimum Design Loads Mr. Paul Greene November 23, 2013 Page 3 For Buildings and Other Structures, for wind speed at this location of 100 miles per hour* for Exposure Category `B", and 39 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 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: 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.
