VaporDry® SA Roof Underlayment: Elevating Modern Roof Protection

Benjamin Obdyke's latest innovation, VaporDry™ SA, is designed to enhance roof protection standards in the industry.

This product utilizes state-of-the-art technology, featuring a 100% fully continuous acrylic adhesive that ensures excellent fastener sealability and vapor permeance. By combining a permeable trilaminate underlayment with the acrylic adhesive, VaporDry™ SA creates a high-performance roof assembly that maximizes the drying potential of the roof while maintaining the overall life cycle of the roof deck. Notably, this underlayment is approved for use on all types of roofing.
