Roof flashing consists of one or several pieces of durable, strong and water-resistant material that is installed on the roof around the openings that disrupt the continuity of the roof, such as the skylights, the vents or the chimneys.
The principal role of roof flashing is to divert water away from areas where it would otherwise tend to accumulate. Made from galvanized steel, aluminum, sheet metal, rubberized plastic or copper, roof flashing comes in strips that are installed around the openings to ensure that the roof is watertight everywhere. This also means that the most obvious signs that indicate a fault of the flashing are leaks or dampness in the attic or in your rooms in the areas underneath the openings sealed with flashing.
There are many causes that can lead to the damage or the improper operation of the flashing on your roof as a Dallas roofer will tell you. Flashing strips need to be installed properly to be able to provide the expected protection – if they are not installed professionally, the edges of the flashing strips don’t adhere properly to the roof surface. The other common cause for flashing problems is the damage sustained by the strips – flashing strips are made from strong and durable materials, but any material can get damaged by extreme weather events and aging can also affect roof flashing.
