Flashing is an important element in any roofing system, as it helps to keep water out and prevent leaks. When installing flashing, it is important to make sure that it overlaps the roof-covering material, in order to create a water-tight seal. On asphalt shingle roofs, for aesthetic reasons, the part of the headwall flashing that extends down over asphalt shingles is often covered with a course of shingle tabs. This helps to create a more seamless look and further protect against water infiltration.
