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. Synthetic underlayment basemat is saturated in asphalt. The addition of fiberglass gives synthetic products superior tear resistance and stability.
Underlayment provides a valuable barrier from any moisture in the sub-floor, plus it dampens sound and helps the flooring sound more like the real thing when you walk on it. Underlayment typically costs between $1.00 to $3.00 per square foot. Donât forget to factor-in the cost of getting rid of your old floor. Depending upon where you live, the floor you are removing and your installer, budget around $2.00 per square foot to have it removed and hauled away.
