Expert Verdict Reviewed by the SuperArbor Pro Desk

Polyester reinforcing mesh is the backbone of long-lasting flashing and seam repairs: apply a base coat of compatible mastic, work the fabric in fully saturated with no dry pockets or wrinkles, then top-coat over it. Choose a 4 in. width for standard seam and flashing details and wider fabric only where the manufacturer’s system calls for it.

Follow the host sealant or coating’s safety instructions when embedding fabric; work on a clean, dry surface and observe roof safety practices.
