How far does drip edge stick out?
The code numbers
The International Residential Code requires drip edge at the eaves and rakes of shingle roofs, and Georgia enforces the 2024 edition with state amendments as of January 1, 2026. The drip edge provisions call for pieces overlapped at least 2 inches, extending at least 1/4 inch below the sheathing and at least 2 inches up onto the deck, fastened no more than 12 inches apart. Underlayment goes over the drip edge at eaves and under it at rakes. Ask your local building department about any local amendments.
The kick off the fascia
Most drip edge profiles have a bent lower lip, sometimes called a kick or hem, that holds the drip line a little away from the fascia board. That small gap keeps water from clinging and running back behind the gutter onto the wood.
Shingle overhang
Shingles should extend past the drip edge enough to shed water into the gutter but not so far that the unsupported edge droops or catches wind. The 1/4 to 3/4 inch range in GAF's instructions is typical; check the instructions for your product.
With gutters
At eaves, the drip edge lip should land inside the gutter, or a gutter apron should bridge the gap. If the lip sits behind the gutter's back wall, water runs down the fascia and rots it. In Georgia downpours this small detail decides whether your fascia lasts.
Signs it is wrong
- Streaks or rot on the fascia behind the gutter.
- Shingle edges drooping over the gutter.
- Gaps where pieces meet without an overlap.
