From the field observation of the property,the existing roof structure was observed as follows: The existing roof structure consists of: • Composition Shingle over Roof Plywood is supported by 2x6 @ 16"o.c.SPF#2 at All Arrays.The rafters are sloped at approximately 35 degree and have a maximum projected horizontal span of 11 ft 5 in between load bearing supports.

I certify that the capacity of the structural roof framing that directly supports the additional gravity loading due to the solar panel supports and modules had been reviewed and determined to meet or exceed the requirements without structural upgrade in accordance with the 780 CMR.
