To Whom It May Concern,
A jobsite observation of the condition of the existing framing system was performed by an audit team of Sunpower Corporation '
as a request from Laguna Consulting Engineers.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 roof,sloped at.19 degrees.The roofing material is supported by
roof plywood and skip sheathing and by the roof framing below.
• The existing roof framing systems of(Roof 1&2)are judged to be adequate to withstan4--tfj 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.fg0�ortr o?ientation.

The scope of this report is strictly limited to an evaluation of the fastener attani�a;,f?tande,Fdym�g;framingAnd supporting
structure,only. All panels,racking and hardware shall be installed per relli`Vprer spe2ilica`tdn§and`'withirl specified design

Per the California Existing Building Code(CEBC)2016 Section 402:3,indicates that alterations to a ,
building that result in less than 5%increase in the gravity loads may be performed without a
structural evaluation of the existing building.The member forces in the area of the propsed solar
array will not increase by more than 5%.Therefore,the requirements of section 3403.3 have been
met and the proposed addition of solar PV is allowed with no further remediation.
