TL;DR
A gutter apron is an L-shaped metal flashing that slips under the first course of shingles and laps over the back edge of the gutter, guiding runoff into the trough instead of behind it. Without it, water wicks around the drip edge and rots fascia and sheathing, a hidden failure often found only when gutters are replaced.
What it means
A gutter apron is an L-shaped metal flashing that slips under the first course of shingles and laps over the back edge of the gutter, guiding runoff into the trough instead of behind it. Without it, water wicks around the drip edge and rots fascia and sheathing, a hidden failure often found only when gutters are replaced. It is standard on roof edges where the decking overhangs little, and on re-roofs the IRC drip-edge requirement is commonly satisfied at eaves with this profile.
