IB-3 StormStopper Plus

IB-3™ StormStopper Plus is a self-adhering, 50 mil, mineral surface roofing underlayment for use under shingles, tile, and other types of roofing. It is constructed from a strong layer of mesh bonded to rubberized asphalt and coated with black stone granules. Comes with a non-removable selvedge edge for a secure seal on overlaps and an advanced adhesive system for a tight bond to the roofing substrate.

IB-3™ StormStopper Plus installs under roofing at the edges and valleys to protect from leaks due to ice dams, storms, frost, and blowing rain. IB-3™ StormStopper Plus is suitable for use in new construction and re-roofing applications.
