Asphalted felts, also known as roofing felt or tar paper, are a type of building material used for waterproofing roofs. These felts are made by saturating a base material, typically made of cellulose or fiberglass, with asphalt. The asphalt provides a waterproof barrier that protects the roof from moisture and other environmental factors. The felts are typically installed in multiple layers, with each layer overlapping the previous one, to create a continuous and durable waterproof membrane. Asphalted felts are commonly used in both residential and commercial roofing applications. They are relatively inexpensive and easy to install, making them a popular choice for many roofing contractors. Additionally, asphalted felts are highly durable and can last for many years with proper maintenance. They are also resistant to fire and other hazards, making them a safe choice for roofing applications. Despite their many benefits, asphalted felts do have some drawbacks. They can be prone to cracking and drying out over time, especially in areas with extreme temperatures or high levels of UV exposure. Additionally, they are not as environmentally friendly as some other roofing materials, as they are made from non-renewable resources and can be difficult to recycle. In conclusion, asphalted felts are a popular and effective roofing material that provide a durable and waterproof barrier for buildings. While they do have some drawbacks, their affordability and ease of installation make them a popular choice for many roofing applications.
