See Energy Star for guidelines on what exactly is covered. It’s your safest bet for information on how to get the credit.

Be warned that not all roofs, not even all roofs with the Energy Star seal, will qualify. Only specially manufactured roofs, as listed on the Energy Star site, are eligible.

Don’t rely solely on contractors who may not know the details or who promise their products will get the credit in order to make a sale.

As of January 2012, the feds haven’t extended the energy tax credit for roofs beyond 2011.
