Short answer
The metal is only part of a gutter price. BLS producer price data shows aluminum mill shapes up about 25% over the latest 12 months, but the index for aluminum and other sheet metal work, closer to finished products, rose about 6.1%. Labor, access, downspouts and the house itself still set most of an estimate.
What the federal price data shows
Federal producer price data shows metal prices climbing sharply, and gutters are made of metal. Gutters of Kent installs seamless gutters across Kent and South King County, with the work done by licensed and insured contractors, and a reasonable question for anyone planning new gutters is how much of that increase lands on an estimate. The short version: some of it, and less than the headline number.
The U.S. Bureau of Labor Statistics publishes producer price indexes that track what domestic producers receive for their output. Over the latest 12 months, the BLS index for aluminum mill shapes rose about 25%, and the index for copper and brass mill shapes rose about 30%. Both readings are preliminary and BLS revises them for several months after release.
Further down the supply chain, the picture is calmer. The BLS index for aluminum and other sheet metal work rose about 6.1% over the same period, and the broader sheet metal products index about 6.7%. These track fabricated products rather than raw metal. BLS used to publish an index specifically for sheet metal roofing and roof drainage equipment, which would have been the closest match to gutters, but that series has been discontinued, so these are the nearest public proxies.
Why a 25% metal increase is not a 25% gutter increase
A gutter price is a stack of costs, and the raw metal is one layer.
| Part of a gutter price | What moves it |
|---|---|
| Aluminum coil | Metal prices, painting, gauge and color, with a lag through distributors |
| Labor | Local wages, stories, access, corners and the length of each run |
| Downspouts and fittings | Count, height, elbows and any buried connection |
| Removal and fascia work | The old system and the condition of the wood behind it |
| Overhead | Insurance, registration, vehicles, equipment and the roll-forming machine |
| Sales tax | 10.4% at most Kent addresses, on the whole contract |
Labor is a large share in this market. BLS wage data for sheet metal workers, the occupation O*NET lists as covering rain gutter and downspout installation, shows a Seattle-Tacoma-Bellevue mean of $52.21 an hour against a national mean of $32.62, about 1.6 times as much. The Seattle figure also includes HVAC duct and commercial sheet metal work, so it is not a gutter installer’s wage, and a wage is not a billing rate, but it shows why local labor and overhead weigh heavily against the metal.
Timing also blunts the effect. Gutter coil reaches an installer through distributors, and a contractor may be working from stock bought at an earlier price. A rise in mill prices tends to show up in coil prices over the following months, not overnight, and a fall can be just as slow.
What it means for a Kent estimate
The budgeting ranges used across this site still apply: 5-inch seamless aluminum, installed, runs a typical Seattle-area range of about $8 to $13 per linear foot, and 6-inch is usually a few dollars more per foot than 5-inch. Standard aluminum downspouts run a national budgeting range of about $30 to $75 per downspout; taller runs, copper and buried connections cost more. One reasonable reading is that a sustained metal increase shows up as estimates landing higher within a range rather than a new range, and that it matters more on jobs where material is a bigger share, such as long single-story runs with easy access.
Copper gutters are the exception worth noting. Copper is the costly part of a copper gutter, so a 30% move in copper and brass mill shapes has more room to show up in the price. The best gutter material guide compares the materials on more than price.

What it does not mean
- It does not mean an old quote was wrong. Two estimates months apart can differ for reasons that have nothing to do with metal, including scope.
- It does not mean waiting will save money. Producer price indexes move both ways, and no one can promise which way next. Gutters that are already failing keep sending water where it does damage while you wait.
- It does not change what a good estimate shows. Linear feet, gutter size and gauge, downspout count and size, hanger type, removal, fascia repair, discharge and sales tax should all be listed. The guide to checking a gutter contractor in Washington covers what else to verify.
The practical takeaway
Compare scope first and price second, ask how long a quoted price holds, and plan around the house rather than the commodity market. If the gutters are sound, a repair may be all they need; the repair vs replacement guide helps decide. When you want a number for your own house, Get an Estimate.
