IB-3 ShingleStarter™ is a 50 mil, self-adhering shingle-starter roofing underlayment. It serves the dual function of replacing conventional starter strips, as well as providing ice and water dam protection in cold climates. IB-3 ShingleStarter has a mineral surface for excellent foot traction.

IB-3 ShingleStarter™ has two self-sealing tabs, each 1.5" nominally from each edge for good adhesion. These sealing strips are protected by a removable release liner, which keeps dust and other debris from settling on the sealing tabs. Keep these liners in place until the shingles are installed. IB-3 ShingleStarter™ installs under roofing at the edges and valleys to protect from leaks due to ice dams, melting snow and blowing rain. IB-3 ShingleStarter™ is suitable for use in new construction and reroofing.
