Asphalt Saturated Organic Roofing Asphalt Shingles Underlayment for Slope Roof
Description:
Asphalt saturated organic roofing asphalt shingles underlayment is an underlayment and moisture barrier between the primary roof (for example asphalt shingles) and the roof decking. It is not intended to be a primary roof. We recommend that the primary roof be installed immediately after the application of the felt.

Uses:
Installation:
1.Do not walk on the felt that is not securely fastened to the roof.
