Gutter cost calculator

How the estimate is built

Linear feet × an installed rate per foot for the material. Downspouts are priced by the foot of drop, so a two-storey house pays for twice the length of a bungalow’s. Taking old gutters down is its own per-foot line. A typical whole-house job lands around $3,223, with most between $2,320 and $4,222 for a new house with nothing to remove.

Profile and seams move the price too

K-style is the common profile and usually the cheapest; half-round in the same material and size usually costs more, and box gutters more again. Seamless runs, formed on site to the length of each eave, cost more than sectional gutters joined from stock lengths — and the joints are where sectional gutters leak. The rates above are for the common case; ask for the profile and the seam method by name on every quote. Guards are a separate purchase, usually a few hundred dollars for a whole system.

Why gutters belong in the roofing conversation

Gutters hang off the fascia and sit under the drip edge, so a re-roof is the only cheap time to replace them — the crew is already at the eave and the drip edge has to be detailed to kick water into the trough either way. See the drip edge guide for that detail; the code asks for a vertical leg of at least 1 1/2 inches and an extension of 1/4 inch below the sheathing, which is what puts the water inside the gutter rather than behind it.

Where the water goes after the spout

A downspout discharging at the foundation is a wet basement with extra steps. Extensions, splash blocks or a buried line moving water six feet away are cheap and are almost never in the gutter quote. Add the line yourself. Blocked or under-pitched gutters are also the most common contributor to eave ice dams.
