What Is Roof Flashing?

What is Roof Flashing? This is a common question among property owners looking to protect their buildings from water damage. Flashing is one of those roofing components that is often overlooked—until it fails. Understanding what roof flashing does, and why it's so important, is essential for maintaining a leak-free structure. This question becomes even more relevant when dealing with roof repairs, home inspections, or planning new construction.

Understanding Roof Flashing and Its Purpose

Roof flashing is a thin material, usually made of metal, that's installed around roof features such as chimneys, vents, skylights, and where the roof meets vertical surfaces like walls or dormers. Its main job is to direct water away from these vulnerable areas, preventing leaks and moisture intrusion. Without proper flashing, even the best roofing system can allow water to seep into your attic or walls, leading to mold, wood rot, and structural damage.

There are various types of flashing, including step flashing, counter flashing, and valley flashing, each tailored for specific parts of the roof. Over time, flashing can deteriorate due to weather, corrosion, or improper installation. That’s why it’s important for homeowners and property managers to have their flashing inspected regularly, especially after major storms or if signs of leaks appear. Addressing flashing issues promptly is a simple way to extend the life of a roof and avoid expensive damage down the line.
