Introduction to Roof Flashings
Roof flashing is an essential element in any roofing system, providing a critical line of defense against water intrusion. It prevents direct water contact at critical junctions, helping to maintain a watertight barrier where different surfaces meet. Typically installed at points where the roof meets a vertical surface — such as around chimneys, valleys, vents, and walls — flashing acts as a barrier that channels water away from these vulnerable areas.
