Drip Edge and Membrane

step1 in steep-slope roofing is the edge flashing one common method is to lay the edge metal under the eaves membrane and over the rake membrane this layering uses gravity to direct water out of the roof assembly another way is to storm proof the edge by folding the membrane down over the gap between roof deck and fascia regardless of how you do it make sure the eaves membrane extends at least 2 feet inside the outer face of the wall this probably means a second course of edge membrane overlap seems about 3 inches depending on what the manufacturer specifies install the edge metal to the eaves beginning at the back of the house working toward the most visible section of roof to avoid gaps that can catch the eye and seal it with another strip of flashing membrane rake membrane only needs to be a single width and should extend up all of the rake edges work the edge metal up the rake from the bottom the upper pieces should overlap the lower ones visible gaps between the flashing are less important then the water injection system that would result from slipping upper pieces under the lower ones the bottom of the rake metal should extend past the eave flashing sweating the details at the edges will keep windblown rain out of your roof by
