Underlayment - - - do I need felt? | Ask The Experts Forum

Guest User 4/19/2009	I am building a small cabin. The roof has 5/8" plywood sheathing. I have covered the entire roof with Grace Ice and Water Shield. Do I need an ADDITIONAL layer of felt (30# or 15#) prior to installing the metal roofing panels?	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13131/find/
Nate Libbey 4/20/2009	No. I see no need to add anything else. Put the metal directly over the Grace.	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13132/find/
