Abstract: The present disclosure relates generally to a roofing system including flashing, for example, suitable for protecting a roof from water leakage. The present disclosure relates more particularly to a roofing system including first, second, and third courses of shingles, where the second course overlaps the first and the third course overlaps the second. A flashing plate is disposed over the first course of shingles and partially under the second course of shingles. The flashing plate and the third course of shingles are spaced apart by a gap in a direction of the slope of the roof between a top edge of the flashing plate and a lower edge of the third course of shingles.
