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?		alice libby 10/4/2006	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/8723/find/
Sure, it will die once underlayment is placed over it. It could be sprayed with a bleach solution first if desired.		Todd Miller Isaiah Industries, Inc. 10/6/2006	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/8724/find/
