But then, there's this:
Q. Is a roof eligible for the residential energy efficient property tax credit?
A. In general, traditional roofing materials and structural components do not qualify for the credit. However, some solar roofing tiles and solar roofing shingles serve as solar electric collectors while also performing the function of traditional roofing, serving both the functions of solar electric generation and structural support and such items may qualify for the credit. Components such as a roof's decking or rafters that serve only a roofing or structural function do not qualify for the credit.
Are you referring to part of the Solar credit, or part of the $500 credit? This is in regards to the $500 non-business credit:
Qualified energy efficiency improvements are the following building envelope components installed on or in your main home that you owned during 2020 located in the United States if the original use of the component begins with you, the component can be expected to remain in use at least 5 years, and the component meets certain energy standards.
Any insulation material or system that is specifically and primarily designed to reduce heat loss or gain of a home when installed in or on such a home.
Exterior windows and skylights.
Any metal roof with appropriate pigmented coatings or asphalt roof with appropriate cooling granules that are specifically and primarily designed to reduce the heat gain of your home.
For purposes of figuring the credit, don't include amounts paid for the onsite preparation, assembly, or original installation of the building envelope component.
To qualify for the credit, qualified energy efficiency improvements must meet certain energy efficiency requirements. See Lines 19a Through 19h, later, for details.
Did they pick a color that meets the requirement? That's one of the first qualifications the installer would show them. Their purchase literature should include an issued certificate, as well, for roofing that qualified. They should ask their installer.
