Roof to wall flashing is a crucial component of a building's waterproofing system, providing a critical seal between the roof and walls to prevent water intrusion and structural damage. This type of flashing is typically installed at the intersection of the roof and walls, where water can easily seep through the joints and seams. The roof to wall flashing is designed to direct water away from the building, protecting the walls and roof from damage caused by wind-driven rain, snow, and ice. It is usually installed in conjunction with other flashing components, such as eave flashing, rake flashing, and chimney flashing, to ensure a complete and watertight seal.
