Question
Which is more energy efficient -- a metal roof or foam insulation?
We are building a new home (about 2600 sq. feet) and want it to be energy efficient yet not too expensive. If you had to pick one of the following, which would they be? metal roof or foam insulation
Answer
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.
