The information you have provided is attached to this letter for reference. Eo3.p�3.n300 The residence is a two story cape style house.You are proposing to erect a PV array on the south slope of the roof.The roof is symmetric about the peak and has a 36-degree pitch.The roof is supported by 2x6 rafters at 16"O.C.These rafter span 15'on the horizontal.Second floor ceiling joists provide a rafter tie below the peak. Knee walls provide intermediate support for these rafters,approximately 6'from the exterior wall at the eaves. The second floor joists are 2x10s and we assume that the joist spacing is 16"OC.There is a center bearing wall under the second floor 2x10 joists.The bearing wall loads are transferred to a center beam supporting the first floor. Lally columns,in the basement, provide intermediate supports for the center beam; and transfer loads to the foundation.The roof deck consists of solid board sheathing.The roofing material consists of asphalt shingles.The photographs you have provided suggest that the roof and supporting members are in sound, serviceable condition. Conclusion: In our opinion the documents you have provided suggest that,the roof is adequate to support the dead load of the proposed PV panels, We base this opinion on the information you have provided and the following assumptions,We assume that, owing to their slippery surface,the solar panels will shed snow better than the asphalt shingle roof.We further assume that the panels will be installed parallel to the roof, eliminating any additional wind load.The ground snow load for Northampton is 55psf. Based on the information you provided,the PV panels weigh approximately 2.6 psf(4.7%of ground snow load).
