What Is Flashing and Why Does It Matter?

Flashing is thin metal material — typically galvanized steel or aluminum — installed at every vulnerable transition point on a roof, including chimneys, vents, skylights, and valleys. It creates a watertight seal that directs water away from seams and joints. Without it, even a structurally sound roof will allow water intrusion.

Wherever your roof meets a vertical surface or changes direction, water naturally wants to collect. Flashing acts as a barrier, channeling that water back onto the roof surface and into gutters rather than into your home or building. Common flashing types include step flashing along sidewalls, counter flashing on chimneys, and valley flashing in low-slope transitions between roof planes.

Flashing failures are one of the leading causes of roof leaks — and one of the most frequently overlooked during routine inspections. Over time, flashing can corrode, pull away from surfaces, or become improperly sealed due to settling or storm damage. A small gap is all it takes for water to work its way into your attic, walls, or ceiling structure.

Proper installation matters as much as the material itself. Flashing must be layered correctly with underlayment and shingles, and sealed with the right compounds for long-term performance. Cutting corners here leads to costly repairs down the line.
