10.920 kW System
To Whom It May Concern:
We have received information regarding solar panel installation on the roof of the above referenced
structure. Our evaluation of the structure is to verify the existing capacity of the roof system and its ability
to support the additional loads imposed by the proposed solar system.
A. Site Assessment Information
1. Site visit documentation identifying attic information including size and spacing of framing
for the existing roof structure.
2. Design drawings of the proposed system including a site plan, roof plan and connection
details for the solar panels. This information will be utilized for approval and construction
of the proposed system.
B. Description of Structure:
Roof Framing: 2x6 dimensional lumber at 24” on center with knee wall. (Main house)
Roof Framing: Flat 2x4 purlins at 24” on center supported by prefabricated 2x6 top chord
trusses at 4’-0” on center.
Roof Material: Composite Asphalt Shingles & Metal Roofing
Roof Slope: 47 and 21 degrees
Attic Access: Accessible
Foundation: Permanent
C. Loading Criteria Used
• Dead Load
o Existing Roofing and framing = 7 psf
o New Solar Panels and Racking = 3 psf
o TOTAL = 10 PSF
• Dead Load
o Existing Roofing and framing = 7 psf
o New Solar Panels and Racking = 3 psf
o TOTAL = 10 psf
• Live Load = 20 psf (reducible) – 0 psf at locations of solar panels
• Ground Snow Load = 40 psf
• Wind Load based on ASCE 7-10
o Ultimate Wind Speed = 117 mph (based on Risk Category II)
o Exposure Category C
Analysis performed of the existing roof structure utilizing the above loading criteria is in accordance
with the 2015 IRC, including provisions allowing existing structures to not require strengthening if
the new loads do not exceed existing design loads by 105% for gravity elements and 110% for
seismic elements. This analysis indicates that the existing framing will support the additional panel
loading without damage, if installed correctly.

D. Solar Panel Anchorage
1. Composite Asphalt Shingles
i. The solar panels shall be mounted in accordance with the most recent Ironridge installation
manual. 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.
ii. The maximum allowable withdrawal force for a 5/16” lag screw is 229 lbs per inch of
penetration as identified in the National Design Standards (NDS) of timber construction
specifications. Based on a minimum penetration depth of 2½”, the allowable capacity per
connection is greater than the design withdrawal force (demand). Considering the variable
factors for the existing roof framing and installation tolerances, the connection using one
5/16” diameter lag screw with a minimum of 2½” embedment will be adequate and will
include a sufficient factor of safety.
iii. Considering the wind speed, roof slopes, size and spacing of framing members, and
condition of the roof, the panel supports shall be placed no greater than 48” on center.
2. Metal Roofing
i. The solar panels shall be mounted in accordance with the most recent EcoFasten Solar
Installation manual. If during solar panel installation, the roof framing members appear
unstable or deflect non-uniformly, our office should be notified before proceedin g with the
installation.
ii. System will be attached to the metal roofing material utilizing the patented EcoFasten Solar
Connection. Installation of the connections shall be in accordance with the manufacturer’s
recommendations.
iii. Considering the wind speed, roof slopes, size and spacing of framing members, and
condition of the roof, the panel supports shall be placed no greater than 48” on center.
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 2015 IRC, 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,
