Every chimney and skylight needs what is referred to as “a back pan”, which includes sheet metal folded at around a 90 degree angle (depending on the slope of your roof) and tucks under the shingles and up under the stucco, siding or counter flashing on the chimney or skylight. Every back pan needs a small 2″ section of metal sticking out 1″ or more from either side of the chimney or skylight to divert water far from the edges.
