What is a valley flashing?

A valley flashing is a specially shaped metal sheet used in roof construction. It is installed in the roof valley—the intersection of two sloping roof surfaces—to efficiently channel rainwater and protect the roof from moisture damage.


What material is a valley flashing made of?

Valley flashings are typically made from durable materials such as aluminum, steel, or zinc. These metals are weatherproof, long-lasting, and corrosion-resistant, making them ideal for outdoor use.


What defines a high-quality valley flashing?

A high-quality valley flashing is characterized by precise workmanship, UV and weather resistance, and a long lifespan. Additionally, an exact fit and easy installation are crucial to seamlessly integrate the flashing into the roof structure.
