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 an 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 Simpson 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.

Solar Energy Contractor shall make an 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. Attached in this package are several calculations showing that the.roof members can support the additional weight of the solar array.
