Roll felt, also known as roofing felt, is a type of material commonly used in the construction industry as an underlayment for roofs. It is made from a combination of organic or synthetic fibers that are saturated with asphalt and then coated with a waterproofing agent. The resulting material is a durable and flexible sheet that can be easily rolled out onto a roof deck to provide a protective layer between the deck and the finished roofing material. Roll felt is typically available in rolls of various widths and lengths, making it easy to customize for different roofing projects. It is commonly used as an underlayment for asphalt shingles, metal roofing, and other types of roofing materials. Roll felt is also used as a moisture barrier in walls and floors, as well as for soundproofing and insulation. One of the key benefits of roll felt is its ability to provide a waterproof barrier that helps to prevent moisture from penetrating the roof deck and causing damage to the underlying structure. It also helps to improve the overall energy efficiency of a building by providing an additional layer of insulation. Roll felt is also relatively easy to install, making it a popular choice for both professional contractors and DIY homeowners. In summary, roll felt is a versatile and durable material that is commonly used in the construction industry as an underlayment for roofs, as well as for moisture and soundproofing in walls and floors. Its ability to provide a waterproof barrier and improve energy efficiency make it a popular choice for a wide range of building projects.
