On the above referenced project,the roof structural framing has been reviewed for additional loading due to the installation of the solar PV addition to the roof.The structural review only applies to the section of the roof that is directly supporting the solar PV system and its supporting elements.The observed roof framing is described below.If field conditions differ, contractor to notify engineer prior to starting construction. The roof structures of(RS1,2&3)consist of composition shingle on roof plywood that is supported by 2x6 rafters @ 24"o.c. with ceiling joists acting as rafter ties.The rafters have a max projected horizontal span of 13'-4",with a slope of 18 degrees. The rafters are connected at the ridge to a and are supported at the eave by a load bearing wall. The existing roof framing systems of(RS1,2&3)are judged to be inadequate to withstand the loading imposed by the installation of the solar panels.Structural reinforcement Is required.If a rafter supporting(RS1,2&3)has a horizontal span greater than 11'-0"then a sister upgrade is required.Stitch new 2x6 DF#2(min)to existing member with Simpson SDW 22300 screws @ 16"o.c.or 10d nails @ 6"o.c..Lap as needed with 4'-0"minimum lap per attached detail. The spacing of the solar standoffs should be kept at 48"o.c.for landscape and 48"o.c.for portrait orientation,with a staggered pattern to ensure proper distribution of loads. The scope of this report is strictly limited to an evaluation of the fastener attachment,underlying framing and supporting structure only.The attachment's to the existing structure are required to be in a staggered pattern to ensure proper distribution of loading.All panels,racking and hardware shall be installed per manufacturer specifications and within specified design limitations.All waterproofing shall be provided by the manufacturer. Domus Structural Engineering assumes no responsibility for misuse or improper installation of the solar PV panels or racking.
