Direct Answer
Yes. Drip edge is essential — and required by most modern building codes. It directs water off the roof and into the gutters instead of letting it wick back under the shingles and rot the decking and fascia. A roof without drip edge is far more prone to edge rot and leaks. We install it on every replacement.
Drip edge is a small piece of metal with an outsized job. It protects the most water-vulnerable part of the roof — the edges — from the rot that starts there and spreads inward.
Why a Roof Needs Drip Edge
- Stops water from wicking back under the shingles at the eaves
- Protects the fascia board and decking edge from rot
- Directs water into the gutters, not behind them
- Helps seal the roof edge against wind-driven rain
- Required by most modern building codes
What Happens Without It
- Water soaks back under the first row of shingles
- Decking edge rots — often the first place rot appears
- Fascia board rots and needs replacing
- Edge leaks develop that are hard to trace
Signs & Symptoms
- Rotting fascia board at the roof edge
- Soft or rotten decking at the eaves
- Water staining behind the gutters
- No visible metal edge under the first row of shingles
Repair Options
- Install drip edge where missing (during repair or replacement)
- Replace corroded or damaged drip edge
- Repair rotted fascia or decking caused by missing drip edge
When to Call a Roofer
If your roof lacks drip edge or the edge is rotting, get it inspected. Adding drip edge stops the edge rot that spreads inward.
How Beyond the Ladder Handles It
We install drip edge on every roof replacement and add it during repairs where it's missing — because the roof edge is where rot starts.
Related Questions
Is drip edge required by building code?
Most modern residential building codes require drip edge at the eaves and rakes. Even where not strictly enforced, it's best practice and we install it on every replacement.
My older roof doesn't have drip edge — is that a problem?
It's a risk. Older roofs often predate the requirement, and edge rot is common on them. If your fascia or decking edge shows rot, missing drip edge is likely a contributor. We can assess and add it.
