If I had to pick,the foam insulation is a better investment in my opinion.

  • Metal roofs have Energy Star certified options which can improve the building's performance and lasts a long time but is very expensive.
  • You can also get standard asphault shingles today with a similar Energy Star rating from companies like GAF which is much less expensive.

You have more wall area than roof area by far.
