Solar Roof™ is a roofing system comprised of both PV and non-PV roofing elements. Please refer to the product data sheets, third-party
certifications, and installation documentation for further information.
Installation of Solar Roof™ over a single layer of composite shingles is acceptable per the manufacturer's installation instructions. If the
existing roof has more than one layer of shingles, or any non-comp shingle roofing, a full tear-off is required. The net installed weight of
the Solar Roof™ system is 3.1 psf, is evenly distributed, and no roofing overlays are permitted. Consequently, the net additional loading
impact to existing gravity load resisting elements is less than 5% and no further analysis was performed.
Where required by the installation manual or conditions above, installer shall perform a full tear-off of all existing layers of roofing material
above existing sheathing/decking. Installer shall verify existing roofing, and sheathing/decking satisfy installation instructions. Installer
shall verify roof framing is in suitable condition that does not exhibit any signs of structural damage which may diminish the capacity of its
members or connections prior to commencement of roofing installation.
I certify that installation of the Solar Roof™ system on this job, given no presence of existing structural damage at time of installation;
meets the criteria outlined in Section 503 of the IEBC/CEBC (alterations to existing structures) and is therefore permitted by code without
alterations or strengthening of the existing framing.
- TYP : Roof DL = 6.5 psf, Roof LL = 20 psf
