Nearly every house in Sioux Falls ends up with seamless aluminum, and that is the right answer for most of them. The decisions worth making are the ones underneath it: how thick the aluminum is, what color, and whether your house is one of the few that should be buying something else.
What the weather here actually does to gutters
Four things wear gutters out in this climate, and each one favors a different material.
Hail dents aluminum. It rarely puts a hole in a gutter, but a storm can leave a run looking hammered while it keeps draining perfectly. Steel dents far less.
Ice loads the hangers. Forty-five inches of snow a year, freeze-thaw cycles all winter, and a trough that can fill with ice before it drains. Hanger spacing matters more than the metal here.
Temperature swings work the joints loose. A 40-foot aluminum run changes length by close to three quarters of an inch between a January night and a July afternoon, and that movement pulls at the sealant in every corner and end cap. It is the reason gutters leak at fittings rather than in the middle.
Sun fades paint. Factory finishes chalk after 15 to 20 years, which usually shows up long before the metal gives out.
The materials, side by side
| Material | Installed | Lifespan | How it handles a Sioux Falls year |
|---|---|---|---|
| Aluminum | $12 to $18 a foot locally | 20 to 25 years | Does not rust, dents in hail, fine under snow load when hung properly |
| Galvanized steel | $8 to $10 a foot | 20 to 30 years | Shrugs off hail and ladders, rusts wherever the coating is scratched |
| Copper | $15 to $25 a foot | 50 years plus | Never rusts, never painted, costs several times aluminum |
| Zinc | $35 to $45 a foot | 50 years plus | Like copper, for architectural work rather than drainage |
| Vinyl | $8 to $12 a foot | 10 to 15 years | Goes brittle in cold. The wrong material for this climate |
Aluminum, and the number nobody mentions
Aluminum dominates for good reasons: it never rusts, it comes in dozens of baked-on colors, and a crew can roll it out of a machine at the curb so each run has no seams along its length.
The number to ask about is thickness. Coil comes in .027 and .032 inch. The heavier one is 18 percent more metal and noticeably stiffer, which matters where a ladder leans and where ice sits. It is also the line most quotes leave out entirely. No published test shows .032 resists hail better, so treat it as a sturdier gutter rather than a hail-proof one, and ask which the price assumes.

Steel, and how much hail you actually get
South Dakota averages about 48 days a year with hail an inch or more, and roughly 14 with stones of two inches or bigger, across thirty years of Weather Service reports. Those are statewide counts, not Sioux Falls counts, and they cluster in May through August. An inch is the size the Weather Service calls severe, and it is about where soft metal starts to show marks.
So the question is not whether hail will hit your gutters. It is whether you mind what it leaves behind. Dented aluminum drains exactly as well as smooth aluminum. If that bothers you, or if ladders and branches are hard on your eaves, galvanized steel at $8 to $10 a foot takes the hit better. On a metal roof, sliding snow is the bigger threat.
Steel rusts, though, and the zinc coating is the only thing stopping it. Every scratch and cut end is a place the protection stops. It is heavier to hang, and fewer crews here run it. Galvalume, steel with an aluminum-zinc coating, sits in between, with a manufacturer claim of 40 to 70 years that no independent test backs up.
Copper and zinc
Copper is $15 to $25 a foot, zinc $35 to $45. Both outlive the mortgage, neither is ever painted, and copper weathers to the green that people either love or find dated.
Understand what the money buys. It is not better drainage. It is a material that looks like it belongs on a house built in 1910, which is where you mostly see it here.
Vinyl
Vinyl goes brittle in cold. Sioux Falls has cold. That is the whole analysis.
Use it on a shed if you like. On the house it is a false economy, and a cracked section in February is a Saturday you will not enjoy.
Color, since it is the part you will look at
Aluminum coil comes pre-finished in a couple of dozen colors, and the finish is baked on at the factory. That is a feature: it holds up far better than anything brushed on later. It is also a constraint, because repainting a gutter well is hard and the color you pick is the color you keep.
Match the trim or the fascia rather than the roof. A gutter reads as part of the eave line, not part of the shingles. White and almond disappear on most houses. Dark bronze and black draw a deliberate line under a light wall, which looks sharp on a newer build and busy on a fussy roofline.
Two practical notes. Downspouts can be a different color from the gutters, usually matched to the siding they run down. And a finish warranty covers the coating cracking, peeling or fading, not the labor to put it right, which is why the installer workmanship warranty is the one that matters.
So what should you buy?
Seamless aluminum in .032, in a color matched to the trim, with 6-inch gutters and 3×4 downspouts if the roof plane needs them. That covers almost every house in this city.
Buy steel if your street gets hail badly and you would rather deal with rust in twenty years than dents next summer. Buy copper if the house deserves it. Buy vinyl for the shed.
Questions about gutter materials
What is the best gutter material for Sioux Falls?
Seamless aluminum in .032 thickness for almost every house. It does not rust, it comes in factory-baked colors, and a local crew can form it on site. Steel is the exception worth paying for if hail or ladder traffic is a real concern.
Are steel gutters better than aluminum in hail?
Steel dents less. It also rusts wherever the zinc coating gets scratched, so the trade is dents now against rust later. Most homes here do fine with heavier aluminum.
Should I use vinyl gutters in South Dakota?
No, other than on a shed or a short sheltered run. Vinyl goes brittle in cold, and a January in Sioux Falls is exactly the weather that breaks it.
How long do gutters last?
Aluminum lasts 20 to 25 years, steel 20 to 30, vinyl 10 to 15, and copper or zinc past 50. Failures here usually start at the joints, not in the middle of a run.
What color gutters should I choose?
Match the trim or the fascia, not the roof. White and almond hide nothing but age gracefully; dark colors read as a line against light siding. The finish is baked on at the factory, so it is not something you repaint well.
Is copper worth it?
On a historic house, or where the look is the point. At $15 to $25 a foot it costs several times aluminum, and it buys a century of service and a patina rather than better drainage.
