Some of the threads relative to standing seam recommend rosin paper over felt underlayment. Is this applicable to the stone-coat metal tile also? And, opinions on the synthetic underlayments?		Ron Corselli 5/30/2004	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/3206/find/
Red rosin paper is used under "long panel" metal roofing systems which are designed to "float" with expansion and contraction. This is not the case with smaller "modular" panel systems such as the stone-coated tiles. I have seen good success with the new polymer-based underlayments. They are durable and tear-resistant. However, they must be installed properly accoridng to the manufacturer's instructions, you must be careful walking on them especially when they are wet, and most of them are not very breathable, furthering accentuating the need for good attic ventilation.
