Roof Structure:2x10 Rafters r, 16 in O.C. Roof Material:Composite shingles Based upon our review, it is our conclusion that the installation of solar panels on this existing roof will not adversely affect the structure of this house. 'fhe design of solar panel supporting members and connections is by the manufacturer and/or installer. The adopted building code in this jurisdiction is the Massachusetts State Building Code, 8th Edition (2009 IBC) and ASCE 7-05. Appropriate design parameters which must be used in the design of the supporting members and connections are listed below: Ground snow load:50 psf per Massachusetts amendments to the IBC(verify with local building department) Design wind speed for risk category 11 structures: 100 mph(3-sec gust). Wind exposure:Category C Our conclusion regarding the adequacy of the existing roof is based on the fact that the additional weight related to the solar panels is less than 3 pounds per square foot. In the area of the solar panels, no 20 psf live loads will be present. Regarding snow loads,it is our conclusion that since the panels are slippery,effective snow loads will be reduced in the areas of the panels. Solar panels will be flush-mounted, parallel to and no more than 6" above the roof surface. Regarding wind loads, we conclude that any additional forces will be negligible due to the low profile of the flush- mounted panel system.It is our conclusion that any additional seismic loadings related to the addition of these solar panels is negligible. During design and installation,particular attention must be paid to the maximum allowable spacing of attachments and the location of solar panels relative to roof edges. The use of solar panel support span tables provided by the manufacturer is allowed only where the building type, site conditions, and solar panel configuration match the description of the span tables.Attachments to existing roof joist or rafters must be staggered so as not to over load any existing structural member. Waterproofing around the roof penetration is the responsibility of others. All work performed must be in accordance with accepted industry-wide methods and applicable safety standards. Vector Structural Engineering assumes no responsibility for improper installation of the solar panels. Please note a representative of Vector Structural Engineering has not physically observed the roof framing. Our conclusions are based upon the assumption that all structural roof components quid other supporting elements are in good condition,free of damage and deterioration,and are sized and spaced such that they can resist standard roof loads.

Consulting Structural and Forensic Engineers -19- IronRidge December 18,2014 Mr,David F. Taggart Page 20 of 20 IronRidge XR100 Rail,Roof Flush Mounting System—Structural Analysis Notes—Tabulated values are based on the following criteria: I. Building mean roof height=30 ft 2. Risk Category I 3. Solar maximum module long dimension is 67.5 inches for Tables l Aa9A,and 78.5 inches for Tables 1 B-9B. 4. Provide 2 in. clear between roof and rail 5. End cantilever span(max)=0.40 x maximum span from above tables b. No rail splices in end spans 7. No rail splices in middle 113 of interior spans 8. Single simple span(s). Spans listed in the tables above may be multiplied by 1.08 for continuous rails of 3 or more spans. Our analysis assumes that the rails, including the connections and associated hardware, are installed in a workmanlike manner in accordance with the "IronRidge Roof Mount Installation Manual" by IronRidge and generally accepted standards of construction practice. Additional information is available at the IronRidge web site, 1ronRidge.com. Verification of PV Module capacity to support the loads associated with the given array shall be the responsibility of the Contractor or Owner and not IronRidge or Starling Madison Lofquist. The adequacy of the supporting roof framing is to be determined by others. Please feel.free to contact me at your conveniencc if you have any questions.

The IronRidge FlashFoot comprises an aluminum block and flashing plate. An L-Foot base is attached using a 5/16" lag screw with a 3 inch minimum embedment into a wood substrate. The wood substrate for the tests consisted of 1/2" CDX plywood over a 2x6 SPF 42 rafter with a specific gravity of 0.42. A full detail can be seen on the attached drawings. The testing data provided shows that the critical failure occurs in one of two ways, pullout of the lag screw from the base material or the shear failure of the L-Foot. Maximum allowable values for these failure conditions were derived using a safety factor of 3.0 on the lowest ultimate load provided by the testing. The maximum allowable uplift reaction of 717 lbs and the maximum allowable downslope (lateral)reaction of 341 lbs are based on the tested criteria. The allowable loads used to develop the tables below have been increased from the tested values above to reflect installation into a wood substrate with specific gravity of 0.50. The increase was determined using the ANSI/AF&PA NDS-2010 National Design Specification (NDS) for Wood Construction adjustment factor of I / 1-(0.50-G)where G is the tested specific gravity. Therefore,the maximum allowable uplift reaction is 779 lbs and the maximum allowable downslope (lateral) reaction is 370 lbs. The maximum allowable spacing of the FlashFoot for common load cases due to wind and snow are shown in Tables 1-9 below. Starling Madison Lofquist, Inc.
