Seamless gutters — increases the estimate
About 15% more than sectional, formed on site from a coil so there are no joints along the run. Joints are where sectional gutters eventually leak, so this is usually money well spent.

Worth knowing
Gutter capacity depends on the profile and the roof area draining into it, not just the length. A 5-inch K-style gutter handles most single-family roofs; large or steep roofs in heavy-rainfall regions want 6-inch.
Where the water goes after the downspout matters more than the gutter. Discharging against the foundation is a common and expensive mistake — extensions or drainage are cheap by comparison.
Guards reduce cleaning frequency; none of them eliminate it. Any product sold as maintenance-free will still need periodic attention.

Capacity depends on profile and roof area, not length; too few downspouts will make a correctly sized gutter overflow; and the fascia they hang from is frequently rotten because the old ones leaked.

Methodology
How this calculator works
How the estimate is built
Material is priced per linear foot for the chosen metal, then multiplied by a profile factor — a 6-inch K-style uses about 22% more material than a 5-inch, and half-round about 45% more. Seamless adds roughly 15%, because the coil stock and the on-site forming machine cost more than stock sections.
Labour uses the Bureau of Labor Statistics mean wage for construction laborers in your state times a contractor burden factor, at a production rate that varies by material, then multiplied for roofline complexity, storeys, and site access. Corners, valleys, and level changes all mean stopping, measuring, and mitring.
Sizing, which matters more than price
A gutter overflows for one of three reasons: the profile is too small for the roof area draining into it, there are too few downspouts, or it is blocked. Only the third is a maintenance problem.
Five-inch K-style handles most single-family roofs. Six-inch is worth specifying on large, steep roofs and in regions with intense rainfall. Downspouts should be one per 30 to 40 feet — we flag it above when your figures imply fewer.
Location and data
Where the numbers come from
Location is optional, and we only ask for a ZIP code or a state — never a street address. A ZIP code is matched to its state using published postal prefix ranges, and that state is used to look up labor and price rows in the tables below. If you leave it blank, or your ZIP cannot be matched, the estimate falls back to a national average and says so on the result.

These are NOT published statistics. As with the interior material baselines, no public agency publishes exterior material prices at this granularity and proprietary construction cost databases cannot be reproduced. Every figure is material only, delivered to a metropolitan supply yard, before regional adjustment and before sales tax. Labor rates are crew-hours or per-unit production rates for a competent crew in normal conditions. See docs/data-sources.md for the full limitation statement.
These are the figures we chose rather than measured. For each one we record the range of values found across references, what we selected, and why — because an estimate you cannot interrogate is not much better than a guess. The 0 marked high risk are the ones most likely to be wrong and most consequential when they are.

Observed range
1 — 1.4 (typical 1.12)multiplier on labour
Why this value
Landscaping, decks, and steep ground below the eave all restrict ladder footing, which is the binding constraint for gutter work. Same band as exterior painting, for the same reason.

Downspout cost eachmedium confidence+
Observed range
25 — 160 (typical 65)USD each
Why this value
Material, elbows, straps, and installation per downspout, scaled by storey count since a three-storey drop uses roughly three times the material. One per 30-40 feet of gutter is the standard guidance, and too few is the most common reason a correctly sized gutter still overflows.
Applies to
United States.
Known limits
Where the water goes after the downspout — extensions, splash blocks, or drainage — is not modelled and matters more for the building than the gutter does.

Fascia repair per linear footmedium confidence+
Observed range
6 — 40 (typical 16)USD per linear foot
Why this value
Replacing rotten fascia before the new run can be hung. User-entered length because it is usually assessed on site. Its presence is diagnostically important: rotten fascia normally means the previous gutters were overflowing or leaking.
Applies to
United States.
Known limits
Rot rarely stops at the fascia — it commonly extends into the rafter tails, which is a structural repair well beyond this line and is not modelled.

Why this value
Simple screens $2-$7.50/ft; micro-mesh $6-$19; surface-tension systems $8-$24 and frequently sold at a premium to that. Selected mid-band values. Guards reduce cleaning frequency; none eliminate it, and the calculator says so rather than repeating vendor claims.
Applies to
United States.
Known limits
Branded surface-tension systems are sold through high-pressure channels at prices well above the material band, sometimes doubling the job cost. The model prices the product, not the sales channel.

Why this value
Sampled pricing spans $3/ft for vinyl to $65 for copper. Selected mid-band values per material. Aluminium is the default for good reason: it covers the great majority of residential installations at a fraction of the cost of the premium metals.
Applies to
United States. Copper pricing tracks the commodity market and moves more than the others.
Known limits
Copper is a traded commodity and its price can move materially within a year. Annual review is marginal for that material specifically.

Observed range

Why this value
Gutter work is done entirely from ladders at the roof edge, so height raises both time and risk more sharply than for siding, which is staged. Selected values sit above the equivalent siding multipliers for that reason.

Why this value
Taking down and disposing of the old run. The high case reflects steel or copper, which are heavy and worth salvaging, and three-storey work.

Why this value
Coil stock plus on-site forming costs more than stock sections, but eliminates the joints where sectional gutters eventually leak. Observed premiums run 5% to 30%; we selected 15% as the centre. Seamless cannot be a DIY option, since it requires the forming machine.
Applies to
United States.
Known limits
The premium is partly a bundling artefact — seamless installers tend to be more established firms with higher overhead — so it is not purely a material cost.

Why this value
Lowest waste allowance on the site. Seamless gutter is formed to length on site, so waste is offcuts at corners only. Sectional systems waste slightly more. 5% covers both.
Applies to
Not regionally variable.

Does not distinguish seamless from sectional, though seamless genuinely wastes less.

Cost factors
What changes the price most
Material
A tenfold spread from vinyl to copper. Aluminium is the default for good reason.
Seamless versus sectional
About 15% more, and it removes the joints that sectional systems eventually leak at.
Profile
Six-inch and half-round use materially more metal per foot than standard 5-inch K-style.
Guards
Can double the cost of the job. They reduce cleaning; none eliminate it.
Storeys and access
Height drives both labour and risk, and makes future replacement expensive too.
Fascia condition
Rotten fascia must be repaired before gutters can be hung, and its presence usually means the old system was failing.
Questions
Frequently asked
How much do new gutters cost?
+
Installed, seamless aluminium commonly runs $8 to $18 per linear foot, so a typical 160-foot single-storey home lands in the low four figures. Copper can be four to six times that. Guards, extra downspouts, and fascia repair all add on top.
Are seamless gutters worth it?
+
Usually yes. They cost around 15% more and remove every joint along the run, which is where sectional gutters leak first. The trade-off is that they must be formed on site by a contractor with the machine, so it is not a DIY option.
Are gutter guards worth the money?
+
It depends on your trees, not on the marketing. Under heavy leaf fall a good micro-mesh guard meaningfully reduces cleaning. On a house with no overhanging trees the payback is poor. No guard eliminates maintenance, whatever the sales pitch says.
How many downspouts do I need?
+
One per 30 to 40 feet of gutter as a starting point, more on large or steep roofs and in heavy-rainfall regions. Too few is the most common reason a correctly sized gutter still overflows, and adding one later is cheap compared with the water damage.
What size gutters do I need?
+
Five-inch K-style is adequate for most single-family roofs. Move to six-inch if the roof is large, steep, or in a region with intense downpours — a steep roof delivers water to the gutter much faster than a shallow one of the same area.
