RE:CERTIFICATION LETTER
Project Address: JACK ZOLLINGER RESIDENCE
152 N CENTER
REXBURG, ID 83440
Design Criteria:
- Applicable Codes = 2018 IEBC/IBC, 2018 IRC, ASCE 7-16 and 2018 NDS
- Risk Category = II
- Wind Speed = 115 mph, Exposure Category B, Partially/Fully Enclosed Method
- Ground Snow Load = 50 psf
- Roof 1: 2 x 6 @ 24" OC, Roof DL = 7 psf, Roof LL/SL = 39 psf (Non-PV), Roof LL/SL = 33.4 psf (PV)
To Whom It May Concern,
Sincerely,
August 11, 2022
Based on this evaluation, I certify that the alteration to the existing structure by installation of the PV system meets the prescriptive
compliance requirements of the applicable existing building and/or new building provisions adopted/referenced above.
Additionally, the PV module assembly including attachment hardware has been reviewed to be in accordance with the manufacturer’s
specifications and to meet and/or exceed the requirements set forth by the referenced codes.
A structural evaluation of loading was conducted for the above address based on the design criteria listed above.
Existing roof structural framing has been reviewed for additional loading due to installation of PV Solar System on the roof. The structural
review applies to the sections of roof that is directly supporting the solar PV system.

Limits of Scope of Work and Liability:
The existing structure has been reviewed based on the assumption that it has been originally designed and constructed per
appropriate codes.The structural analysis of the subject property is based on the provided site survey data.The calculations
produced for this structure's assessment are only for the roof framing supporting the proposed PV installation referenced in the
stamped planset and were made according to generally recognized structural analysis standards and procedures.All PV modules,
racking and attachment components shall be designed and installed per manufacturer’s approved guidelines and specifications.
These plans are not stamped for water leakage or existing damage to the structural component that was not accessed during the
site survey.Prior to commencement of work,the PV system installer should verify that the existing roof and connections are in
suitable condition and inspect framing noted on the certification letter and inform the Engineer of Record of any discrepancies
prior to installation.The installer should also check for any damages such as water damage,cracked framing,etc.and inform the
Engineer of Record of existing deficiencies which are unknown and/or were not observable during the time of survey and have
not been included in this scope of work.Any change in the scope of the work shall not be accepted unless such change,addition,
or deletion is approved in advance and in writing by the Engineer of Record.
