Drip Edge with Flat Shelf

Often associated with gutter installation and plumb fascia boards, perimeter drip edge flashings can create a shelf or ledge about three inches from the roofs edge. This shelf creates a flat roof area at the roof’s perimeter. Since this roof system is not a flat roof, the perimeter flashings are not designed to allow for sitting water. During light rains and morning dew water seeps under the roof system and deteriorates the perimeter decking sub-fascia board and fascia board. This can be resealed as a temporary fix, but should be replaced for a more germinate measure.
