1.0 existing condition(Warm Roof)
Design Snow Loads: 28 PSF(Existing—Unobstructed Warm Roof)
25.15 PSF(New Condition—Slippery Surface on Cold Roof)
Basic Wind Speed: 100 MPH From Table R301.2(4)
Importance Factor: 1.0
Exposure: B
Analysis Results:
General Considerations
➢ The proposed solar panels impose a total weight of approximately 3 pounds per square foot(PSF)
on the roof surface. From a practical standpoint,the International Residential Code allows up to
2 roof coverings on a residential dwelling. Each layer of roofing imposes a net load of about 2.5
to 3.0 PSF on the roof. From this perspective, since the existing roof will have only a single layer
of shingles, a second layer is allowed to be added by the code without analysis. This 2"d layer of
shingles essentially weighs the same as the proposed solar panels that will be added instead.
➢ Materials such as metal roofs or solar panels are considered a slippery surface. Since the solar
panels are mounted slightly above the roof line, it would be conservative to consider a thermal
factor, Ct of 1.1,treating the panel surface as a cold roof,rather than a warm roof. Based on the
roof slope,the snow load is reduced by 10%compared with the snow loading directly on the
existing shingled roof surface. This reduction equates to approximately 2.85 PSF which partially
offsets the weight of the panels.
Gravity Loading:
Given the size,spacing and configuration of the existing roof framing,we have determined that the
existing framing is adequate to support the additional loading from the solar-electric system, including the
panels,and all connections without the need for any strengthening.
It is our understanding that the panels will be installed using Zep racking with leveling feet at a spacing of
approximately 32 inches on center(e.g., every other rafter). The leveling feet will be fastened directly
into the existing joists with 5/16"diameter by 4" long lag screws. In addition, it is important that the
leveling feet support locations be staggered between adjacent panels so that no single rafter supports more
load than under the existing conditions.
Wind Loading:
Based on our calculations,the net wind loads imposed on the roof framing with an attachment spacing as
indicated above will be less than the current loading on the rafters. In addition,provided that the leveling
feet are attached to the roof in a typical staggered fashion, the overall wind loading imposed on the
structure and the individual framing members will not be impacted to any great extent.
Conclusions:
Our evaluation of the proposed solar-electric installation has established that the framing is adequate to
