Flashing installation

Why install flashing?

Even if an exterior siding – regardless of its material – has no visible holes or places where water can seep in, there will still be water infiltration. In doing so, the flashing and counter flashing are absolutely essential to ensure the waterproofing of the coatings. Prevent unpleasant surprises caused by water infiltration such as crumbling brick, rusty metal and rotting wood.

What is flashing?

Flashing is a metal sheet, usually aluminum or pre-painted steel, used to uniformly join two surfaces of an exterior building. For example, flashing is found at the junction of a roof and a chimney. The flashing plays an extremely important role and must be properly installed to be properly sealed.

What is the purpose of the flashing?

Flashing and counterflashing are used to direct water away from the interior of siding or roofing. In other cases, drainage flashing is installed on the structure to direct water to the exterior of a siding. A brick siding normally has an evacuation flashing that is used to direct water that seeps behind the siding.

What are the types of flashings?

The self-adhesive membrane flashing is installed around certain junctions such as chimneys, skylight perimeters, door and window surrounds. It is important to coat the structure well with self-adhesive membrane at the junction of two types of coatings.

Metal flashing, also known as counter masonry and head rim, must be positioned between an exterior wall and other materials. It is found at the base of masonry walls, lightweight siding or any other type of covering (Canexel, aluminum, all types of wood).
