Expert Verdict — Reviewed by the SuperArbor Pro Desk
Install head flashing behind the weather-resistive barrier with proper end dams so water exits at the sides, not behind the siding. Match the color to your trim for a clean look where the flashing remains exposed. Order by the carton and plan lengths to minimize laps on wide window combinations.
Metal flashing edges can be sharp; wear cut-resistant gloves when handling and cutting.
Order Mastic window head flashing in White or Black to protect your window openings.
