Proper Flashing Around Windows and Doors
This visual representation depicts the crucial role of flashing in preventing water damage. Correct installation is essential for long-term protection.
Imagine a window framed within the house’s exterior wall. First, a layer of flashing extends from the window’s exterior frame, up and over the window’s top edge, and then down the other side, creating a continuous, slightly overlapping, cap over the window frame. This flashing extends several inches beyond the window frame on all sides. Next, a second layer of flashing is installed, butting up against the first layer at the bottom of the window. This second layer extends horizontally outwards, away from the house. This creates a “step” effect, diverting water away from the window. The siding then overlaps the second layer of flashing. All seams and overlaps are carefully sealed with a high-quality sealant to prevent water penetration. The same principle applies to doors, ensuring water runs away from the opening rather than into the house.
