Home > Flashings > Applications: Windows


  1. Always start flashing from the bottom, working your way to the top. This prevents water from getting in.
  2. For windows, install J bottom first, making sure the flashing runs past the window.
  3. Install the sides, make sure to lap it at the bottom corners.
  4. Install the drip at the top of the window making sure it is long enough to cover the J trim.
