Vreeland Design Associates Re: Dan Darci, 247 Riverside Drive, Florence, MA: Stru tural assessment of existing house and new garage roofs to support proposed PV solar .and arrays. I have investigated the house and new garage roof framing fir the proposed PV solar panel installations. Based on the Assessor's records, the original 2 story, 22'x 25' gabled roof house was constructed around 1869. A 2-story, 22'x 20' appears to hay- been constructed at a later date. A new 24'x 24', 1-story garage has recently been completed. 14 PV solar panels are to be installed on the southwest facing roof of the original house and 10 so ar panels on the southeast facing roof of the new garage. The house roof is framed with 2"x 43/4"r.fters installed 24"on-center spanning 10'-6"with a 7.5/12 roof pitch. The attic floor framing is se lured to the exterior walls and rafters preventing the roof from spreading. The garage roof is fram d with 2x6 attic storage roof trusses, designed and manufactured by UFP Belchertown, LLC, inst lied at 24"on-center, spanning 24' with a 5/12 roof pitch. The trusses have been designed for a c 5 psf roof snow load, a 15 psf dead load on the top chord, and a 117 mph V,u basic wind speed. he house and garage roofing are composite asphalt shingles. The house rafters supporting the solar panels have to long o a span to support the solar panels and meet the requirements of the current building code. Reinfor•e the existing southwest rafters supporting the solar panels by sintering new 2x6x8', centere► on the length of the existing rafters and nailed with 2 -nailgun l0d/12d nails at 8"-9" on-center :long the length of the new 2x6s. I have reviewed the mounting details for the proposed PV s s lar panel arrays. Based on my calculations and a PV solar panel unit weight of 46± lbs, wit the attachment points of the solar panel arrays placed at a maximum of 4' on center and stagg=red to minimize the load to any one reinforced house rafter, as outlined above, and the garage ro f trusses are adequate to support the proposed PV solar panel arrays and the snow and wind load equirements of the current 9th Edition of the MA State Building Code for the City of Northampton Please contact me if you have any questions or need additio al information.
