Skylight Flashing

Flashing around skylights is usually a continuous piece. Skylights are raised using a wood curb, allowing enough room for flashing material. The National Roofing Contractors Association recommends that this is an 8-inch (200-mm) vertical run. If you are re-roofing your house you may need to raise or remove your skylight for the installation of proper flashing. Even if your skylight is manufactured with flashing attached, you may need additional flashing.
