Description
Style D, also known as u201cDL,u201d u201cdrip edgeu201d or u201ceave drip,u201d is a type of roof flashing, applied to the edge of a roof prior to shingling. Itu2019s shaped more like a u201cTu201d than a u201cDu201du2014but thatu2019s construction terminology for you. One arm of the u201cTu201d extends a couple inches onto the roof, the other arm extends about 1 inch beyond the roof and the lower leg extends about 1 inch down onto the fascia. It performs a variety of functions: It helps protect the edges of exposed plywood and OSB sheathings, it creates a clean edge for supporting the edges of shingles and it helps deflect water away from eave boards and/or into gutters. (Water can easily run 1 inch uphillu2014Style D prevents that.)
