I just received an estimate for a metal roof with the contractor recommending stripping all layers of shingles (4 layers in some areas and putting 30lb felt down between the structure and metal roof) Is this correct?

Yes that would be correct, doing the opposite would probably be against county codes	Guest User 5/21/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13310/find/
I'm not so sure felt is the way to go, it get's pretty hot under the metal and would guess there might be some adheasion if the panel sits directly on the metal.	Guest User 5/21/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13311/find/
Well I've never heard of the felt sticking to the panels,felt is used all the time rusty. But if your not comfortable with that use grace triflex or some other synethtic underlayment.	Guest User 5/22/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13312/find/
The synthetics are good in that they act both as an underlayment and as a vapor barrier.	Todd Miller Isaiah Industries, Inc. 6/1/2009	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/13313/find/
