Flashing is a sheet of thin, impervious material used to prevent water penetration or seepage into a building and to direct the flow of moisture in walls.

Why do we use flashing?

In modern buildings, flashing is intended to decrease water penetration at objects such as chimneys, vent pipes, walls, windows and door openings to make buildings more durable and to reduce indoor mold problems. Metal flashing materials include lead, aluminium, copper, stainless steel, zinc alloy, and other materials.

What is flashing on a home?

As all builders know, flashing is a thin sheet or strip of water-resistant material that's installed at roof intersections and projections, around windows and doors, and along the tops of foundation walls to direct water flow away from the home.
