It is our understanding that the structural components of the existing roof framing are in good condition and free of damage. The design of the solar panel racking(mounts,rails,etc.)is by the manufacturer or contractor. Solar module mounting hardware is engineered by the manufacturer. Vector Structural Engineers has relied on site survey information (photographs,measurements&diagrams)provided by the installer for roof framing information. Resin.] Parameters Code:Massachusetts State Building Code(780 CMR Chapter 16, 8th Edition(2009 IBC)) Occupancy Category:II Design wind speed:90 mph (3-sec gust)per ASCE 7-05 Wind exposure category:C Ground snow load: 40 psf Existine Roof Structure Roof structure:2x6 rafters @ 16"O.C. Roofing Material: asphalt shingles Roof slope:35° Connection to Roof Mounting connection:(1)5/16" Lag Screw w/min.2.5" embedment at max.48"O.C. Conclusions Our conclusion regarding the adequacy of the existing roof is based on the fact that the additional weight of the solar array is 3 psf or less. In the area of the solar array,other live loads will not be present or will be greatly reduced. The member forces in the area of the solar panels are not increased by more than 5%; thus, the stresses of the structural elements are not increased by more than 5%. Therefore, the requirements of Section 3403.3 of the Massachusetts State Building Code (780 CMR Chapter 16,8th Edition(2009 IBC))are met and the structure is permitted to remain unaltered. The solar array will be flush-mounted (no more than 6" above the roof surface) and parallel to the roof surface. Thus, we conclude that any additional wind loading on the structure related to the addition of the proposed solar array is negligible. The attached calculations verify the capacity of the connections of the solar array to the existing roof against wind (uplift), the governing load case.The connections to the existing roof shall be spaced at 48"maximum. 651 W.

All work performed must be in accordance with accepted industry-wide methods and applicable safety standards. The contractor shall notify Vector Structural Engineerine, LLC should any damage,deterioration or discrepancies between the as-built condition of the structure and the condition described in this letter be found. Particular attention must be paid to the maximum allowable spacing of connections and the location of solar panels relative to roof edges. Connections to existing roof framing must be staggered so as not to overload any existing structural member, except at array ends. The use of solar panel support span tables provided by others is allowed only where the building type,site conditions, site-specific design parameters, and solar panel configuration match the description of the span tables. Electrical engineering is the responsibility of others. Waterproofing around the roof penetrations is the responsibility of others. Vector Structural Engineering assumes no responsibility for improper installation of the solar array. VECTOR STRUCTURAL ENGINEERING.LLC en ROGER;. . / VII >` 1 FIS A ..
