Your shopping list

A rough takeoff to load the truck, not a substitute for measuring on site. Hangers at your spacing, sealant about one tube per 6 joints (corners + end caps + outlets). Order a little extra.

How the takeoff is figured

Every number comes straight from what you typed. No magic, no markup, nothing hidden.

Gutter coil = length × (1 + waste%). 200 ft + 8% = 216 ft
Hidden hangers = one every 24 in along the run. 2,400 in ÷ 24 = 100
Downspout pipe = drops × average height. 6 × 10 ft = 60 ft
Drop outlets = one per downspout. Elbows = your elbows-per-drop.
End caps = runs × 2. Miters = your corner count.
Sealant = about one tube per 6 joints (corners + end caps + outlets).
