The solar panels shall be mounted to the ballast system in accordance with the most recent “Unirac <br />Installation Manual”, which can be found on the Unirac website (http://unirac.com/roofmount/). If during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified before proceeding with the installation. 2. Ballast system shall be placed on the roof in accordance with Unirac recommended layout and per their installation instructions. 3. To avoid overloading the existing structure during staging and installation, materials to be installed on the roof shall not be stacked in one area on the roof. Components shall be stored on the ground and placed on the roof in their final position. Based on the above evaluation, this office certifies that with the racking and mounting specified, the existing roof system will adequately support the additional loading imposed by the solar system. This evaluation is in conformance with the 2019 California Building Code, current industry standards, and is based on information supplied to us at the time of this report. Should you have any questions regarding the above or if you require further information do not hesitate to contact me. Very truly yours, Scott E.
