A waterproofing roll roofing tar paper serves as a protective layer against water. It is installed on roofs before shingles or other roofing materials are laid. It is primarily made of felt paper that has been soaked in tar, making it waterproof. Below are the types of waterproofing rolls:

• Asphalt-saturated felt

  This type of roll roofing tar paper is made from organic felt paper. It is soaked in asphalt, making it waterproof. It is commonly used as a roofing underlayment in residential homes. Its affordability and decent protection make it a good choice for many homes. It is also lighter than most options, making it easy to handle and install.

• Polyester felt

  This type of waterproofing roll roofing tar paper is made from synthetic polyester fibers. It is then impregnated with asphalt to make it waterproof. It is more durable and resistant to tearing than other options. It is also lightweight and easy to handle. It has a higher waterproofing capacity, making it a good choice for areas with high rainfall.

• Tar-soaked felt

  This type of roofing roll is similar to asphalt-saturated felt. However, it uses tar instead of asphalt. This makes it a good choice for roofs in hot climates. It is also more resistant to UV radiation and organic decay. It is also heavier and thicker than other options, providing better protection.

• Rubberized asphalt roofing underlayment

  This type of roofing roll is made from rubberized asphalt. It is specifically designed for use as roofing underlayment. It is more waterproof than traditional options. It also has a peel-and-stick adhesive backing. This makes it easy to install and provides a strong, water-tight seal.

• Self-adhesive modified bitumen sheets

  This type of waterproofing roll is made from modified bitumen sheets. It is characterized by self-adhesive backing. This makes it easy to install and provides a strong, water-tight seal. It is more expensive than traditional options. It is also more suitable for flat or low-slope roofs.
