How Many Pieces of Roof Drip Edge Do You Need?

Enter eaves and rakes as separate takeoffs — you don't need a simple L×W rectangle like many roof-length × width tools — then get pieces to buy with waste and full-stick rounding.

Quick preset
Eaves gutter line Rakes gable slopes

Measure eaves along the gutter line; measure rakes along each sloped gable edge.

Total of every eave where drip edge meets the gutter line.

Sloped gable/rake edges. Use 0 for eaves-only jobs.

Planning note

Gutters, fascia, shingles, and ice-and-water shield are separate orders. Type D vs Type F changes the profile, not the piece count above.

Worked Examples

Ranch gable — 100 × 40

100 ft eaves · 40 ft rakes · 10 ft sticks · 10% waste

Measured length140 ft
Order length (with waste)154 ft

For a simple 40×30 footprint that's just 2L + 2W, plus waste, then round up to full sticks.

Large ranch — 150 × 60

150 ft eaves · 60 ft rakes · 10 ft sticks · 10% waste

Measured length210 ft
Order length (with waste)231 ft

Keep eaves and rakes separate when the roof isn't a clean rectangle.

Eaves only — no rake

100 ft eaves · 0 ft rakes · 10 ft sticks · 10% waste

Set rake to 0 if you already counted rakes elsewhere, or the job is eaves only.

Type D vs Type F Drip Edge

Pick the profile for eaves and rakes. The piece count above stays the same either way.

Type D at eaves

T-style with a kick-out — the usual eave pick so water clears the fascia into the gutter.

Type F at rakes

Longer upper flange, common on rake edges and re-roofs. Match it to your underlayment sequence.

Frequently Asked Questions

Add every eave and rake where drip edge goes on. Bump that total by about 10% for waste, divide by the stick length you buy (usually 10 ft), and round up. That whole-stick count is what you order — no need to force a simple L×W rectangle.
Most stores sell 10-foot sticks (some carry 8-foot or 12-foot). Set stick length under Advanced before you order. Face height and profile (Type D vs Type F) are a product choice — they don't change the piece math above.
Start at 10% for overlaps, corners, and a few damaged pieces. Bump it up if you have lots of hips, valleys, or short leftover runs. Rounding up to full sticks already covers some of that cutting loss.
Overlap joints by about 1–3 inches so water can't sneak through the seam. That lap is why a 10% waste buffer is a solid default — full-stick rounding may cover some of it too.
No. Gutters and downspouts are a separate drainage order. Fascia boards live on the soffit and fascia calculator. Here you're only ordering roof-edge drip edge sticks.
