Flashing is a thin material, typically made of metal or plastic, installed to protect specific areas of a roof from water infiltration. It is commonly used around chimneys, vents, skylights, and along roof valleys. The primary purpose of flashing is to redirect water away from critical points where it could enter the building.

There are several types of flashing, each serving a specific purpose in protecting your roof. Step flashing is used around chimneys and walls, overlapping each piece to create a watertight seal. Continuous flashing runs along the length of a wall or roof edge, providing a consistent barrier against water. Valley flashing is installed in roof valleys, where two slopes meet, to prevent water from pooling and leaking through. Vent flashing is designed for roof vents and pipes, ensuring that water doesn’t penetrate around these protrusions.

Proper sealing with roofing cement or caulk is also crucial to prevent water from seeping beneath the flashing.

Homeowners should include flashing in their routine roof inspections, especially after severe weather events. Checking for loose or damaged flashing, as well as signs of wear, can help identify problems before they escalate.
