Why would electric generating panels impact your gas bill? and why would you not put them back after a new roof?

  The removal of the previous system (that was supposed to help with water/room heating) didn't increase the gas bill

    right, but why not reinstall the photovoltaics? those generate electricity and offset electric bill and to a great degree even after 10 years..

      That's only true if the site is well suited for it. It seems very possible that after running the system for 10 years they found it it wasn't worth the cost/effort reinstallation and maintenance work for what they'd get out of it, even long term.
