Turnback flashing is often used for sidewall applications. This flashing features a design that protects against leaks at the endwall, sidewall, or roof top applications. It is used to keep water from going past the edge of the flashing. Turnback flashing is commonly substituted in place of angle flashing or step flashing, allowing for a cleaner, smoother look. It is a versatile product that can be used on a commercial or residential roof.
