Description

Universal TPO Inside/Outside Corner (White)

Flashco’s universal TPO inside/outside corner flashing is an injection-molded, weldable accessory designed to quickly seal 90° roof corner details. The one-piece design offers a uniform, professional finish while reducing labor versus field-fabricated corners.


Key Features:

  • Universal Corner Design: Flashes either 90° interior or 90° exterior corners by cutting the riser as indicated in the diagram.
  • Labor-Saving Installation: Pre-molded part saves significant time compared to field fabrication.
  • Weldable TPO Construction: Made from injection-grade TPO for reliable heat-weld compatibility.
  • Consistent Finish: Provides a better fit and more uniform appearance than field-flashed corners.

Its sculpted, uniform form elevates the entire edge condition, making the roofline look cleaner and more resolved. It’s the kind of finishing piece that turns performance into polish—essential for a truly elevated build.

"Got the navy version and it feels sturdy in the hand. Used it during a move and nothing shifted. Button is a bit stiff at first but loosens up with use. Shipping was quick and the item delivered."

"Went with the XL and the material feels solid and well-made. I've had it on the kitchen counter daily. One minor scuff on the corner, purely cosmetic. I'm in Denver, CO. No complaints so far."
