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, 8'- 2" +/- high, built from nominal 2" x 6" dimensional lumber joists at 16" o/c, typical. There is an attached "A" framed garage roof assumed to be similarly framed. The maximum roof joist span length is 15' — 6" +/- excluding reductions for collar ties supports. Two layers of roof shingles are assumed. Materials are assumed as minimum Hem-Fir #2 grade, conservatively (low allowable stresses), with standard construction components (better grade lumber may have been used). 2" x 8" collar ties are installed at 32" +/- o/c spacing on the joists, set 24" +/- below the top of the 2" x 8" ridge beam in the main "A" roofs'/attic's full length, in panel installations areas, for adequate roof reinforcing. There are no other roof joists or ridge beam supports, the full length of roof, down to framing below. The main attic and roof framing were mostly accessible by access panels at the site inspection and evaluation, so a complete assessment and confirmation of framing spacing, sizes and condition was able to be performed for this roof. The garage roof received a partial assessment 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. r Mr. Paul Greene February 26, 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 42 materials. Considering the low roof slopes, array sizes; full/limited access to confirm roof joists' size, spacing, condition; and collar ties, the panel supports shall be set/attached to every third joist for lateral installations over joists. No panel supports ap cing shall be greater than three(3)roof joist spaces, or 48" o/c,to be shown in the PV 2.0 Roof Layout plan(s). Note—Layout Array Drawings#1, #2 &#3 submitted for review, shows every four joists, 64" o/c maximum panel support spacing, and which need to be revised to the above spacing. The panel supports shall be installed in staggered patterns to ensure the proper load distribution, and with no more than three supports placed on any single roof joist, except at ends of layouts. After revising,these layouts 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 three joist spaces 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, 8t'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 ASCEISEI 7-10 Minimum Design Loads Mr. Paul Greene February 26, 2014 Page 3 For Buildings and Other Structures, for wind speed at this location of 100 miles per hour* for Exposure Category `B", and 19 degree roof slopes on the dwelling's roof areas. Ground snow load is 40 p.s.f.* for Exposure `B",Zone 1 (per ASCE/SE17- 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 '/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.
