To Whom It May Concern, 16:16:56-08'00'
Ajobsite observation of the condition of the existing framing system was performed by an audit team of Sunpower Corporation
as a request from Laguna Pacific Group.All review-is based on these observations and the design criteria listed below and only
deemed valid if provided information is true and accurate.
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(Roof 1&2)consist of composition shingle on lx decking that is supported by 2x4 rafters @ 24"o.c.with
ceiling joists acting as rafter ties.The rafters have a max projected horizontal span of 5'16",with a slope of 21 degrees.The
rafters are connected at the ridge to a ridge board and are supported at the eave by a load bearing wall.
The existing roof framing systems of(Roof 1&2)are judged to be adequate to withstand the loading imposed by the installation
of the solar panels.No reinforcement is necessary.
•
The spacing of the solar standoffs should be kept at 72"o.c.for landscape and 72"o.c.for portrait orientation.
The scope of this report is strictly limited to an evaluation of the fastener attachment,underlying framing and supporting
structure only. All panels,,racking and hardware shall be installed per manufacturer specifications and within specified design •
limitations.All waterproofing shall be provided by the manufacturer. Laguna Pacific Group assumes no responsibility for
. misuse or improper installation of the solar PV panels or racking.
