What Is Chimney Flashing?
Chimney flashing is a system of metal pieces (usually aluminum, copper, or galvanized steel) installed where your chimney meets the roof. It creates a watertight seal that prevents rain, snow, and ice melt from seeping into the gap between the chimney and the roof deck. explore this guide

How Flashing Works
A proper flashing system consists of multiple layers:
- Step flashing: L-shaped metal pieces woven into the roof shingles along the sides of the chimney
- Counter flashing: Metal pieces embedded in the chimney mortar joints that overlap the step flashing
- Base flashing: Covers the bottom (uphill) side of the chimney
- Saddle/Cricket: A peaked structure behind the chimney that diverts water around it
