Expert Verdict Reviewed by the SuperArbor Pro Desk

The All-Flash collar is a good choice when crews stock one flashing for mixed vent-pipe diameters, cutting inventory on service trucks. Slide the collar down over the pipe and dress the base flange into the roofing system per the membrane or shingle manufacturer’s details. Keep the smaller fixed-size No-Calk flashings on hand for tight stacks where a snug collar seat is preferred.

Work from a stable, properly secured ladder or roof access and follow fall-protection requirements when installing flashings on any roof.
