What is roofing underlayment? Roofing underlayment is a water-resistant or waterproof barrier material that is installed directly onto your roof deck. It is applied under all other roofing materials as an added layer of protection from severe weather. There are three main types of roofing underlayment: Asphalt-saturated felt. Non-bitumen synthetic underlayment. Synthetic underlayment (technically non-bitumen synthetic underlayment) is the preferred underlayment of most roofing professionals today.
