COUNTERFLASHING Meaning and
Definition
-
Counterflashing is a term used in construction and architecture to describe a type of protective covering or layer that is installed to prevent moisture or water penetration in areas where two different materials meet, most commonly at the intersection of a roof and a wall. It is typically placed on top of step or base flashing, which is the first line of defense against water infiltration.
Counterflashing is designed to be an additional barrier that is installed vertically on the wall and overlaps the top portion of the base flashing. Made from durable materials such as metal or PVC, it acts as a cap or barrier, preventing water from seeping behind the underlying flashing layers. This protective layer is crucial in diverting water away from sensitive areas, specifically joints and connections, that are prone to leaks and water damage.
The installation process for counterflashing varies depending on the type of wall material and the specific construction project. Most commonly, it is securely anchored into the wall using screws or other fasteners and then sealed with a waterproofing agent or caulking to further prevent water infiltration.
Counterflashing serves as an essential component in building envelope integrity by providing an extra layer of protection against moisture intrusion. By effectively preventing water from seeping into vulnerable areas, it helps to increase the longevity and durability of a structure by reducing the risk of water damage, such as rotting of wood, corrosion of metal components, or deterioration of masonry materials.

Etymology of COUNTERFLASHING
The word "counterflashing" is a combination of two words: "counter" and "flashing".
The term "flashing" originally comes from the Middle English word "flashen", which means "to dart or spring forth". In the context of construction, flashing refers to a thin sheet of metal or other waterproof material that is installed to prevent water intrusion and redirect it away from critical areas, such as joints, seams, or intersections of a building.
The prefix "counter" indicates opposition or conflict, denoting something that is contrary or opposing. In the case of "counterflashing", it refers to a second layer of flashing that is installed to protect the primary flashing from potential damage, typically placed on top of the primary flashing and shaped in a way that diverts water away from the joint or intersection.
