Which of the following best describes sheet metal flashings?

Sheet metal flashings play a crucial role as accessories for roofing systems. These components are typically made of durable materials such as aluminum, copper, or galvanized steel and are designed to direct water away from critical areas of the roof, such as transitions, penetrations, and joints.

Their primary function is to prevent water infiltration and protect the underlying structures from moisture damage. By serving as a barrier, sheet metal flashings enhance the overall integrity and longevity of roofing systems, making them essential accessories rather than structural components or insulation materials.

Understanding the role of sheet metal flashings helps in recognizing their importance in a well-designed roofing system, contributing to effective waterproofing and protection against the elements.
