Why Use a Drip Cap?
Gravity is a relentless contractor. Without a drip cap, surface tension allows water to "wrap" around the top of your window trim and seep into the wall cavity. This flashing acts as a physical barrier, forcing water to drop straight to the ground, keeping your framing bone-dry.
Pro Tip: For the best seal, ensure the house wrap or building paper is integrated over the vertical leg of the drip cap before installing your siding.
