The Nonbusiness Energy Property Credit which expired at the end of 2017 has been extended through the end of 2019 along with other tax extenders passed by Congress and signed by the President in December 2019.
The IRS will be updating Form 5695 and the 5695 instructions for 2019 for the Nonbusiness Energy Property Credit.
You should wait for the form to be updated and finalized so that you can get the credit for the roof on your 2019 tax return.
