From a field inspection of the property,the existing roof support structures were observed by Astrum Solar auditors as follows: The roof structure of(Roof A)consists of composition shingle on roof plywood that is supported by nominal 2x6 rafters @ 16"o.c.,paired with nominal 2x6 ceiling joists @ 16"o.c..There are 2x6 collar ties at every rafter which frame out an enclosed attic.The rafters are supported mid-span by veritcal struts which work with collar ties and ceiling joists to provide a truss system to support the rafters above.The rafters have a max projected horizontal span of 6'-6",with a slope of 45 degrees.The rafters are connected at the ridge to a continuous 2x8 ridge board and are supported at the eave by a load bearing wall. The roof structure of(Roof B)consists of composition shingle on roof plywood that is supported by nominal 2x10 rafters @ 16"o,c.,paired with nominal 2x8 ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 12'-0",with a slope of 45 degrees.The rafters are connected at the ridge to a continuous 2x12 ridge board and are supported at the eave by a load bearing wall. The roof structure of(Roof C)consists of composition shingle on roof plywood that is supported by nominal 2x6 rafters @ 16"o.c.,paired with nominal 2x8 ceiling joists @ 16"o.c..The rafters have a max projected horizontal span of 11'-1",with a slope of 45 degrees.The rafters are connected at the ridge to a continuous 2x8 ridge board and are supported at the eave by a load bearing wall.There are 1x8 vertical struts at 16"o.c.that is approximately 8'-0"from the ridge to provide extra bracing to the rafters. The existing roof framing system of(Roof A)is judged to be adequate to withstand the loading imposed by the installation of the solar panels. No reinforcement is necessary. The existing roof framing system of(Roof B)is judged to be adequate to withstand the loading imposed by the installation of the solar panels. No reinforcement is necessary. The existing roof framing system of(Roof C)is judged to be inadequate to withstand the loading imposed by the installation of the solar panels.Structural reinforcement is required. New 2x6(min)x T-0"long collar ties shall be installed at 16"o.c.with 6- 10d nails at each end on(Roof C). 5� F A "ALIT i"I ,fflurk', R,'�A '�41 H"H F Beach Residence, Andover 1 r9 8955 F-ler7kels Lane, S4.lite 5103 U, AnnaEjuli;Junction, NID 20701. �A PH O11JL 1 X80 903.51 3O FAX 443u267,C)036 ST UM L ., vswwaskrunisolar.corwi The spacing of the solar standoffs should be kept at 48"o.c.with a staggered pattern to ensure proper distribution of loads. I further certify that all applicable loads required by the codes and design criteria listed below were applied to the Unirac Solarmount solar rail system and analyzed. Furthermore,the installation crews have been thoroughly trained to install the solar panels based on the specific roof installation instructions developed by Unirac Solarmount for the racking system and Ecofasten for the roof connections. Finally, I accept the certifications indicated by the solar panel manufacturer for the ability of the panels to withstand high wind and snow loads.
