Vreeland Design Associates Re: Greg Sandler, 310 South St,Northampton, MA: Structural assessment of existing house roof to support proposed solar array. On 4/22/16, I conducted a site visit to investigate the existing roof framing in the area of the proposed PV solar panel installation. The 29'x 38', 2-story colonial style house was constructed in 1900. 25 solar panels are proposed on the south roof of the house. The rafters are full dimension 3x4 installed at 16"-24"on-center, spanning 6'-7"to an 8x7 purlin beam located at the mid-point between the 8x8 cave beam and ridge. The roof has a 7.5/12 slope. The purlin beam is supported by 3x6 posts at 7'± on-center and those posts are supported by a 6x6 beam resting on full dimension 2x6 ceiling joists, installed at 16 on-center which in turn are supported by bearing walls below. The second floor ceiling joists are attached to the top of the purlin beams and prevent the upper rafters from spreading. The 8x8 cave beam, supporting the lower rafters, is approximately 2'-4"above the first floor ceiling joists. The roofing is asphalt shingles. Note: A purlin beam post is missing approximately 7' in from the west gable end wall and a new post, 3 —2x4 nailed/screwed together is sufficient, needs to be installed in-between the purlin beam and 6x6 beam resting on the floor joists. I have reviewed the mounting details for the proposed array. Based on a PV panel unit weight of 381 lbs, with the attachment points of the array placed at a maximum of 4' on center and staggered to minimize the load to any one rafter, the existing roof framing is adequate to support the proposed PV solar array and the snow load requirements of the current MA State Building Code. Please contact me if you have any questions or need additional information. Sincerely, Of DAVID A.
