Wind loads have been calculated for a speed of 157 MPH. The roof pitch and construction have
been analyzed, and the photovoltaic system structure designed to resist resulting uplift and
downward forces. The attached drawings and diagrams reflect a design that safely transmits
dead and live loads to the roof. To the best of my professional knowledge and belief, the subject
construction and photovoltaic system installation will be in compliance and designed to 2017
