Specific mention of roofs was removed from the credit by Congress in the Inflation Reduction Act. There is still a credit for insulation materials that might include roofs. You have to prove both of these statements are true:
- A building envelope component is "any insulation material or system, including air sealing material or system, which is specifically and primarily designed to reduce the heat loss or gain of a dwelling unit when installed in or on such dwelling unit".
- To be eligible, the component or system must meet these efficiency standards: the prescriptive criteria for such component established by the most recent International Energy Conservation Code standard in effect as of the beginning of the calendar year which is 2 years prior to the calendar year in which such component is placed in service.
So if the roof is rated by the IECC, and if the roof meets or exceeds the standard for energy saving roofs that were published in 2021, then a roof could qualify. If IECC doesn't rate roofs, or if your roof doesn't meet the IECC standard, then the roof doesn't qualify.
If your roof does meet IECC standards, you would enter it in the program section for insulation systems. Only include the cost of materials, don't include labor or installation.
