Structures, 2015 American Forest & Paper Association, National Design
Specification for Wood Construction, Local Municipal Code, and all other
codes which are adopted by reference or enacted by law.
Assumed Design Parameters:
The existing structure has been built under a building permit and is in its
original condition. The existing roof structure is capable of its code
required live load and the ability of the roof structure to support live loads
has not been substantially reduced by the age of the structure, termites or
mold, or unauthorized modifications to the existing structure. Solar Energy
Contractor shall make inspection of the existing roof framing system prior
to installation of the roof mounted solar energy system to verify that the
existing roof is capable of supporting minimum roof live loads.
Assumed Design Parameters:
All 2x members are grade Douglas Fir #2 or better
All 4x members are grade Douglas Fir #1 or better
All Roof Connectors are Simpsons Strong-Tie or Equal
All Concrete Foundations are fc = 2500 psi or stronger
Original Structure was built to the Type-V Wood Framed Standards
of the Applicable Building Code at the time of Construction.

Note to Building Official:
Based upon a review of the proposed plans I am confident that the
existing roof framing system is capable of safely supporting the additional
loads caused by the solar photovoltaic energy system. The contractor
shall field verify that the existing roof structure is in its original permitted
condition and verify that it can support the normal code required roof live
loads. Attached in this package are several calculations showing that the
roof members can support the additional weight of the solar array.
Furthermore, an analysis of the solar array's support for wind forces and a
seismic analysis of the existing structure are also included.
