Deductions & credits

As indicated by Opus 17, move past the clean energy credit and go to the 'Energy-Saving Improvements' credit to select the cost of any material for insulation that may be included for your roof.  You cannot include any labor costs for preparation, or assembly.  

Also, as indicated by DoninGa, the only mention of roof is related to solar clean energy.
