Roofing shingles felt paper.

Roofing felt is a layer of tar paper installed beneath the shingles to provide a backup waterproof membrane in case of leakage. Of course it is a bit more technical than that but this is the basic idea behind how felt works. This is coated with a protective coating such as asphalt which repels water but allows the underneath product to breathe so air and humidity don t get trapped. It s a protective second layer that s installed between the roof deck and roof shingles that seals and protects your roof against leaks.

Roofing felt also known as tar paper provides a protective underlayment over the roof deck and beneath the shingles. Generally speaking roofing felt is a felt paper that is soaked in asphalt and other water resistant compounds to produce a membrane. Item 656632 model 0903000.

The purpose of the shingle underlayment is to provide an additional moisture resistant layer to back up your roof shingles. It also offers fire resistance required for home construction.

Because your roof deck might not lie perfectly straight or flat a layer of roof paper gives an even uniform surface upon which you can install your shingles. It improves look and uniformity.
