Tar Paper ASTM #30 Asphalt Roofing Felt Paper Asphalt Roofing Membrane

 

Roofing felt, also referred to as "builder's felt" or "roofing felt paper," is underlayed on roofs before coverings like asphalt or wood shingles are added. Resembling black tar paper, roofing felt's main purpose is to prevent moisture from leaking into a roof. Available in rolls, roofing felt is made with a fiberglass or polyester center and saturated with pieces of asphalt, tar and bituminous coal. It is sometimes coated with sand 

The most commonly used is #15, which comes in rolls 3 feet wide, is 144-feet long and covers approximately four squares per roll, or approximately 400 feet of roof. Felt #30 also comes in rolls 3 feet wide and covers approximately two roof squares per roll, or approximately 200 feet. The rolls can be cut to various lengths, as needed

Used

 

Asphalt shingles are the most commonly used covering for homes in the United States. Four out of five homes are covered with asphalt shingles, according to the Asphalt Roofing Manufacturers Association. The type and amount of roofing felt to apply varies according to roof slope. If the slope is between 3:12 and 4:12, use two layers of #15 felt for asphalt shingles. If the slope is greater than 4:12 -- which provides more water drainage from the roof -- use one layer of #15 felt. Use #15 for asphalt shingles weighing 240 pounds per square or less; consider using #30 only if shingle weight is heavier than 240 pounds.

Tips:

When applying roofing felt, pay careful attention to areas that receive the most water runoff, including roof hips, ridges and areas around adjoining walls. Cover those areas with an additional 6 inches of felt, from each direction.
