How to calculate drip edge length
This calculator finds total drip edge length needed for a roof by adding the eave length and rake length together — drip edge is installed along both the horizontal eaves and sloped rakes of a roof.
How the calculation works
Total drip edge = Eave length + Rake length.
Example
120 ft of eave length plus 80 ft of rake length: Total drip edge = 120 + 80 = 200 ft.

Pro Tips for Drip Edge Length
- Drip edge is typically sold in 10-foot sections — round your total up to the nearest number of whole pieces needed.
- Add a small overlap allowance (a few inches per joint) since pieces overlap slightly where they meet.
Common Drip Edge Length Mistakes to Avoid
- Forgetting to include rake length, and only calculating drip edge for the eaves, which would leave the sloped edges without proper drip edge protection.
