Jack writes from Salem, Virginia: "In November 2006, I purchased a new roof. The type of shingles used was Owens Corning, Oakridge PRO 30® AR shingles. Do these shingles qualify for a tax credit?"

Answer: Wouldn't that be nice? Unfortunately, shingles are not included in the list of products that qualify for a credit under the Energy Policy Act of 2005. For a list of the products that do qualify for a tax credit, go to the How to Save on Your Taxes with Insulation page of the Owens Corning Web site. The products are listed on the back of the Owens Corning Manufacturer's Certification Statement.
