I’ve Never Heard of It. What is Counterflashing?
Counterflashing refers to the metal flashing that is installed over the top metal of base flashing. It prevents water infiltrating a building where two different construction materials meet.
“Thanks, I somehow know less now.” Don’t worry, we got you.
What is Base Flashing?
- Base flashing, or just flashing, is a thin sheet of metal that is applied at the bottom of a vertical surface like a wall. Imagine where a chimney or dormer intersects with the rest of the roof.
- Protects construction materials from exposure to water.
- It is most commonly made of galvanized steel but can also be made of aluminum or coated copper.
- Very important- we’re big fans.
What is Counterflashing?
- Counterflashing is an additional piece of metal applied over the top edge of the base flashing.
- Further directs water away from the vulnerable joint.
- Provides a watertight seal to ensure integrity of the materials underneath.
- Super important- we’re even bigger fans.
