Flashing around windows and doors is primarily intended to prevent which of the following?

Flashing around windows and doors is primarily designed to prevent water infiltration. This is achieved by directing water that may collect around these openings away from the building structure and ensuring that moisture does not seep into the building envelope. Properly installed flashing acts as a barrier, channeling water away from vulnerable areas, which helps to protect the interior from potential water damage, mold, and rot.

Although preventing drafts, insects, or noise may be secondary benefits, the primary purpose of flashing is focused on water management. By ensuring effective drainage and sealing around window and door installations, flashing plays a crucial role in maintaining the integrity and longevity of a building’s exterior.
