Flashing is considered a weatherproofing element because its primary function is to direct water away from critical areas of a roof, such as chimneys, vents, and joints where different roofing materials meet. By creating a barrier against moisture, flashing helps prevent leaks and water intrusion, which can lead to significant damage within a building.

This component is typically made from materials like metal, plastic, or rubber that are chosen for their durability and ability to withstand exposure to the elements. Flashing is essential in maintaining the integrity of the roof and ensuring that water does not penetrate areas where it could cause structural or interior damage. Through its weatherproofing role, flashing plays a pivotal part in extending the lifespan of roofing systems and safeguarding the interior of the home from water-related issues.
