Expert Verdict Reviewed by the SuperArbor Pro Desk

Choose Matrix 201 when a flashing detail on an SBS modified bitumen roof needs maximum bond strength and the flexibility to track roof movement; Matrix 202 or 203 are good-quality or general-purpose alternatives for less demanding details. Tool it warm and work it into the flashing Pan or membrane-to-wall joint with a notched trowel for full coverage. Its rubberized SBS chemistry suits high-movement penetrations like guide wires, antennas and sign supports. Follow GAF’s system specifications to keep warranty terms intact.

Solvent-containing asphalt cements are flammable and vapor-forming: ventilate the work area, avoid ignition sources, and follow the safety data sheet and roof fall-protection requirements.
