What is the difference between felt and asphalt? Felt is on a roll and is installed one strip at a time. Asphalt is applied in wet form, like you would apply tar to a driveway, and is spread over the area of the roof. A layer of gravel is then spread across the top of the asphalt, whilst still wet, which helps to protect and prolong the life of the asphalt.
What is Asphalt?
Asphalt, which is also known as bitumen, is derived from crude oil. It is found in liquid or semi-solid form and is somewhat refined before being used. It varies in grade and consistency, with different types of asphalt being used for different purposes. In addition to roofing, it is also used to cover roads, parking lots, tennis courts and driveways.
