Expert Verdict Reviewed by the SuperArbor Pro Desk

T-joints are where field-seamed details most often fail, so preformed patches are cheap insurance on any large TPO roof. Match the patch color to the membrane and weld with clean, dry, properly prepped surfaces. Probe every finished patch seam as part of quality control.

Hot-air welding tools and hot membrane can cause burns; use gloves and follow roofing site safety procedures.
