Finish the window flashing by overlapping the top over the side pieces.
How to do it
- Cut flashing tape to be at least two inches longer than the width of the window plus side jamb flashing.
- Make sure top of head flashing is at least two inches above where the top of the head flange ends.
- Make sure head flashing runs at least one inch past the jamb flashing on each side of the window.
- You can use ZIP System® 3-3/4 inch tape for this application, but to get a better adhesion surface and width to make sure a good shingling pattern is maintained, use 6 inch ZIP System flashing tape.
