Expert Verdict — Reviewed by the SuperArbor Pro Desk
Never simply weld a lap over an existing seam crossing; a T-joint patch welded first, then lapped over, is the standard way to keep three-layer intersections watertight. Keep the membrane surface clean and dry before welding and test seams with a probe. On older PVC, verify the sheet is still weldable before patching.
Hot-air welding tools reach high temperatures; wear heat-resistant gloves and follow the manufacturer's Safety Data Sheet and roof-safety practices.
