One of the final steps to complete your new roof is the installation of drip edge and gutter apron. These are strips that help to direct water away from the roof and prevent insects from entering your home. A drip edge is a narrow strip that covers the edge of the roof and allows water to easily flow into the gutter. A gutter apron adds another 2 inches of protection over the gutter to protect from water damage in homes that face harsh weather conditions.
