What Is An Inside Corner Flashing?

A D Cone Standard Flashing is a specialized roofing component designed to protect the corners of roofs from water damage. It is a conical structure with specific dimensions, including a 7-inch top diameter, 14-inch bottom diameter, and a height of 12 inches. This flashing features a 6-inch flange with a 1-inch overlap and is designed with a square base for added stability.
