Slope Roof Waterproof Material Asphalt Roofing Felt Paper roofing tar roll

 

(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.

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.

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. In regions where snow and ice prevail during the winter months, adding an ice and water shield in addition to roofing felt makes a watertight and energy efficient covering for the roof. Other options for underlayment include nonbitumen synthetics and rubberized asphalt.
