I had 3 roof estimates. 2 said we could roof over existing shingles...and the other said he couldn't because we had a lot of moss growth. Can you install metal roofing over shingles that have moss on them?

Sure, it will die once underlayment is placed over it. It could be sprayed with a bleach solution first if desired.
