When it comes to the roof, there are many elements that optimize its efficiency. With each component performing a specific function, the overall condition is better preserved. People can be easily overwhelmed with the many parts of a roof. In an effort to help people become more familiar with their home’s roof, we at Nickerson Roofing would like to look closer at the flashing that is on your roof.

Flashing is Part of Weather Resistant Barrier (WRB) System

To prevent the passage of water into a structure from a joint, the flashing is part of the weather resistant barrier system, or WRB; this component is the thin pieces of impervious material that is installed in specific locations on the roof. In order to decrease water penetration of the different components of the building, including the vent pipes, chimneys, walls, windows, and door openings, the flashing on modern homes make buildings more durable and minimizes indoor mold problems. Stainless steel, aluminum, copper, zinc alloy, and other materials are what metal flashing products derive from. To minimize water penetration, builders used creative methods including angling the roof shingles away from the joint before the availability of sheet products for flashing. Covering seams between roofing materials with mortar flaunching, building steps into the sides of chimneys to throw off water, and placing chimneys at the ridge are other methods often utilized. Manufactured flashing reduces water penetration at obstacles like the vent pipes, chimneys, walls as well as window and door openings, making buildings more durable and reducing indoor mold problems.

By design, flashing can be concealed or exposed at the time of installation. Directly installed, usually around wall penetrations such as window and door openings, concealed flashing is either metal or a flexible material with an adhesive backed. The exposed flashing is typically a sheet metal. Because it is one of the first barriers of defense against the elements in order to preserve your home or business, the flashing installation is crucial.
