Self-adhering polymer-modified bituminous membrane that seals around every fastener — the detail layer that stops ice dams and wind-driven rain from becoming callbacks.
Self-adhering polymer-modified bituminous membrane for eaves, valleys, skylights and other detail areas. Rubberized asphalt backing seals around fasteners to prevent leaks.

Typical placements we supply for. If your assembly is not listed, send us the detail drawing and we will confirm the right grade.
Ice-dam protection along the roof edge where freeze-thaw cycles back water under shingles.
Continuous membrane through the valley where water volume and debris load are highest.
Flashing integration at penetrations where shingle-only detailing tends to fail.
Vents, pipe boots and transitions that need a self-sealing layer around fasteners.
Rubberized asphalt closes around nail and staple penetrations instead of leaving a hole.
Formulated for application in cooler conditions, extending the usable installation season.
The release liner splits down the middle, so aligning long eave runs takes less labour.
Always follow the roof or wall system manufacturer's instructions and the applicable local building code.
