Mule-Hide PVC T-Joint Patch, Gray or White, Single-Ply Membrane Flashing

The Mule-Hide PVC T-Joint Patch is a preformed flashing piece used to reinforce T-joint intersections on PVC single-ply membrane roofs. It is available in gray or white to match the field membrane, and each patch is sold as an individual piece. It bonds with hot-air welding to strengthen seam intersections and prevent leaks at membrane crossings.

Key Features:

• Preformed shape: Preformed to fit T-joint intersections, saving field cutting and fitting time.
• PVC membrane: Made from PVC membrane material compatible with PVC single-ply roof systems.
• Two color choices: Offered in gray or white to match common PVC membrane colors.
• Hot-air weldable: Welds to the surrounding PVC membrane with standard hot-air welding equipment.
• Reinforces intersections: Adds reinforcement at seam crossings where membrane stress concentrates.

Expert Verdict Reviewed by the SuperArbor Pro Desk

T-joints are one of the most common failure points on single-ply roofs because overlapping welds pile up thickness and stress. A preformed PVC T-joint patch gives a clean, properly dimensioned reinforcement instead of a field-fabricated patch. Match the patch color to the field membrane for a consistent appearance and to avoid uneven heat absorption.

Follow roof safety protocols when working near roof edges, and use proper ventilation and heat-resistant gloves when hot-air welding PVC membrane.
