Construction: Weatherproofing and Sealing

In the construction world, flashing refers to thin pieces of material, typically metal, used to prevent water from penetrating a building's structure. It's installed at joints and intersections, such as around windows, doors, chimneys, and roof valleys.

Why is flashing important?

Flashing is essential for protecting your home from water damage. Water can seep into the smallest cracks and openings, causing rot, mold, and structural damage. Flashing acts as a barrier, directing water away from these vulnerable areas.

Without proper flashing, water can penetrate the roof, walls, and foundation, leading to costly repairs. In addition, mold growth can pose health risks to your family. By investing in quality flashing and proper installation, you can prevent these problems and protect your home for years to come.

Types of flashing

There are several types of flashing, each designed for specific applications:

  • Roof flashing: This is used to seal the areas around chimneys, vents, and skylights. It can also be used in roof valleys, where two roof planes meet.
  • Wall flashing: This is used to seal the areas around windows, doors, and other wall penetrations. It can also be used at the base of walls, where they meet the foundation.
  • Drip edge flashing: This is installed along the edges of the roof to prevent water from running down the fascia and causing rot.
  • Step flashing: This is used to seal the area where a roof meets a wall. It consists of individual pieces of flashing that are installed in steps, overlapping each other.

Materials used for flashing

Flashing can be made from various materials, including:

  • Aluminum: This is a lightweight and corrosion-resistant material that is commonly used for flashing.
  • Copper: This is a durable and long-lasting material that is often used for high-end homes.
