Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pre-formed inside corners eliminate the hand-cut folds that commonly cause hot-air weld failures at curb and wall details. Set the corner in position, tack it, then weld all seams with consistent temperature and speed, probing the welds afterward. Keep a supply on hand for any EverGuard PVC or PVC XK job; they are inexpensive insurance against the most frequent leak points in single-ply detailing.
Use heat-welding tools with care on the roof, watch surrounding membrane for heat damage, and follow roof-safety and fall-protection practices.
Add GAF EverGuard PVC Pre-formed Inside Corners to your kit for faster, more reliable curb and base flashing details.
