Solar Panel Post Installation Letter
Dear Ms.Grey:
Per your request, we have reviewed photographs and a post-installation checklist for the above-referenced
site.
Based upon our review, it is our conclusion that the installation of solar panels on this existing roof
occurred in accordance with the building code and our original requirements as stated in a letter
dated April 8,2019. Rafter size and spacing has been verified to match the original design. Water damage
was not encountered during work on and under the existing roof. No pre-installation splits,cuts,breaks,or
visible sagging was encountered in the existing roof framing. After installation was complete, it was
verified that all roof-penetrating fasteners actually penetrated into the roof framing and did not visibly split
the framing members. No existing damage to any existing structure was discovered and no damage was
caused to any existing structure during installation, according to the installer. All roof penetrations were
sealed and flashed as a means of waterproofing.
Our conclusions are based upon our review of the photos and a checklist prepared by the installer. This
letter does not waive the installer of any responsibility for improper installation. As stated in a previous
letter, our conclusion regarding the adequacy of the existing roof is based on the assumption that all
structural roof components and other supporting elements are in good condition.
We hope this meets your needs. If you have any further questions regarding this matter, please call this
office at your convenience.
Very truly yours,
