It has been determined by this office that the rafters as specified above, exceed the allowable span for the total design loading.Attached are repair details that, when Installed will render the roof design structurally adequate to support the new PV modules In addition to the code required design loading. Attach the module rail brackets to the roof with 5/16'lag bolts at 48 on center maximum.Provide a minimum of 2'of penetration into the wood members. Mounting Plane 2 The calculations for these structural members are attached.It has been determined by this office that the roof, as specified above, Is adequate to support the new PV modules In addition to the code required design loading. Attach the module rail brackets to the roof with 5/16"lag bolts at 48 on center maximum. Provide a minimum of 2"of penetration Into the wood members. This office has determined that the installation of the PV System as specified above will meet the structural requirements of the 2015 International Residential Code with Massachusettes Amendments 9th Edition and ASCE7-10 when installed in accordance with the manufacture's Instructions.
