State tax filing

Thank You for the answer...under the FAQ it says "If you made energy efficient improvements to your home like energy-saving roofs, windows, skylights, and doors, you'll be able to claim the Nonbusiness Energy Property Credit for 10% of amounts paid for qualified energy efficiency improvements, up to a lifetime cap of $500"

 

Does anyone happen to know what constitutes an energy-saving roof?  I had the roof redone with new shingles.
