Generally, no. Home improvements add to your cost basis and may reduce your capital gains when you sell, so keep track. But they are not tax deductible.
Insulation systems designed to reduce heat gain or loss are eligible for a tax credit of up to 30% on the materials only (not including labor) with a maximum credit of $1200. An efficient roof does not count (heat reflecting granules, etc.). But if you had additional insulation installed in the attic under the roof deck, you can claim the credit on the cost of the insulating materials. If your bill does not show the cost of materials vs labor, you can make a reasonable allocation, but you might have to prove it if audited.
