What is Peel and Stick Roof Underlayment?
Peel and stick roof underlayment, also known as self-adhering membrane, is a type of roofing material designed to provide a waterproof barrier. It comes with a sticky backing that adheres directly to the roof deck, eliminating the need for nails and reducing installation time. This product is especially beneficial in areas prone to water infiltration, such as valleys and eaves.
