ASTM D4869 American Roofing Felt Paper Asphalt Saturated Organic Felt Underlayment
(felt paper, asphalt felt paper) is a sheet material impregnated with bitumen (asphalt), similar to tar paper, used in building construction. The term felt comes from the historical method of making the base material. Felt is an unwoven fabric that is produced by matting fibres under pressure. The fibres form the structure of the fabric.

Asphalt-saturated heavy-duty roofing felt is available in 15- and 30-pound weights. The best weight for roofing felt is the 30-pound product, because it provides thicker and stronger footing for roofers that does not tear out, especially on steep roofs where footing is critical. Besides that benefit, if shingles come loose during a storm and tear off, the 30-pound roofing felt stays intact, whereas 15-pound tar paper may not. This offers your home protection until you can repair it.
