First things first, we need to define what a drip edge is, to begin with. According to Wikipedia, in roofing, a drip edge is a “metal flashing or other overhanging components with an outward projecting lower edge, intended to control the direction of dripping water and help protect underlying building components.” Drip edges are installed with an intended tilt that is meant to guide water away from your roof while at the same time ensuring your roof’s foundation is not exhausted prematurely by holes and fissures.
A drip edge goes along the edge of the roof under the shingles. Though it is generally overlooked by homeowners, a drip edge is an important component of the roofing system. Some homeowners even tend to exclude drip-edges from a roofing project in order to save money. In the short term, doing without drip edges may be less costly but in the end, lack of it will lead to damage that is expensive to fix.
There are two broad types of drip edges:
These are used on low incline roofs. L shaped drip edges are located on the roof deck, on top of the fascia board. Before installation, the roofing material is held tightly using glue to the outside edge.
Usually used with metal and standing seam roofing. An open hemmed drip edge prevents water from moving upwards (through capillary action) and passing the drip edge metal.
