Expert Verdict — Reviewed by the SuperArbor Pro Desk
T-joint cover patches prevent leaks at three-seam intersections in single-ply TPO roofs; keep them on hand for new installs and repairs. Match patch color to the field membrane, clean and prep the weld area, and follow GAF detail 105A for proper overlap. Use only on 60 mil or heavier TPO membranes as specified.
Hot-air welding poses burn and fire hazards; follow GAF installation instructions, job-site fire safety practices and local code.
