This underlayment features excellent asphalt saturation for effective waterproofing. Bituminous felt is a form of waterproof sheeting that is used to cover flat roofs or as an underlay beneath slate or tile roofing. Also the textured fabric lets steep sloppy walkability. The substance itself is made from bitumen which comes from the distillation of crude oil that has been either mixed with sand or crushed limestone.
