Roof Flashing

Roof flashing is an essential component in roofing systems designed to prevent water from seeping into the home through joints, seams, or intersections. It’s typically made of durable materials such as aluminum, galvanized steel, copper, or plastic, all of which are resistant to corrosion and designed to withstand harsh weather conditions. Flashing is installed around roof features like chimneys, skylights, vents, valleys, and at the junctions where different roofing materials meet.

The primary function of roof flashing is to redirect water away from vulnerable areas where the roof’s surface may be broken or uneven, such as along the edges of vents or around a chimney. These are areas where water can easily pool or penetrate if not properly sealed. By channeling water away, flashing helps prevent leaks, which can lead to costly repairs or structural damage over time.

There are several types of flashing, each serving different purposes. Step flashing, for example, is used around chimneys and walls, while counter flashing is often paired with step flashing for extra protection. Valley flashing is used in the valleys of a roof to manage the flow of rainwater, ensuring it moves off the roof efficiently without causing damage.

Proper installation and maintenance of flashing are critical to the longevity of your roof. If flashing becomes damaged or worn out, it can lead to leaks and water damage. Regular inspections are recommended, especially after storms, to ensure flashing remains intact and continues to protect your home from the elements.
