Aluminum Gutters: A Twin Cities Contractor's Complete Guide

I run aluminum gutter on Twin Cities homes pretty much every week the weather lets us. Five-inch seamless on most suburban houses. Six-inch on the bigger custom builds and anything with serious water volume coming off the roof. K-style profile on almost everything, half-round when the architecture asks for it.

This is the post I wish every homeowner could read before they call three contractors and get three completely different numbers. No fluff. Just what I'd tell you if you caught me in the driveway after an install.

The Quick Answer

For most Twin Cities homes, 5" seamless aluminum K-style is the right gutter. Roughly $7 to $12 per linear foot installed. Lasts 25 to 35 years if it's hung right. Available in 20+ standard factory-painted colors.

Step up to 6" seamless when:

Your roof is over 4,000 square feet
You've got a steep pitch dumping a lot of water at the corners
Heavy tree cover and you want extra capacity before debris chokes the flow
The architecture supports the deeper profile (some homes just look better with a 6" trim line)

Step up to half-round when the home is historic or Craftsman-style. Costs roughly 50 to 80 percent more than K-style.

If you want the full breakdown on how we scope and price this work, our gutter installation page lays out the process.

What "Aluminum Gutter" Actually Means

Aluminum is the standard residential gutter material in North America. When someone says "gutters," they usually mean aluminum. It's what 90+ percent of the homes I drive past in Eden Prairie, Plymouth, Edina, and Minnetonka have on them.

Three coil specs actually matter:

Gauge thickness. Standard is 0.027" coil. Heavy-duty is 0.032" coil — about 20 percent more durable, costs about 15 percent more. I spec 0.032" on lake-area homes, anywhere the previous gutter showed ladder damage, and on north-facing runs that take the brunt of ice. Standard 0.027" is fine for most projects.

Painted finish. Factory-painted coil (Kynar 500 finish) holds color for 30+ years without chalking or fading. Field-painted gutter is shorter-lasting and almost nobody does it anymore. If a contractor is quoting field-painted aluminum, ask why.

Seamless vs sectional. Seamless is the standard now. The coil comes on a trailer, runs through a brake on-site, and gets cut to length right at your house. One continuous piece per run. Sectional gutter has joints every 10 feet — more seams, more failure points. I haven't quoted sectional on new residential work in years.

5-Inch vs 6-Inch Aluminum Gutters

This is the question I get at every estimate.

5-inch K-style gutter handles roughly 5,500 square feet of roof area at standard rainfall intensity. Most Twin Cities homes (1,500 to 3,500 square feet of roof) are well inside that handling capacity. For a typical 1990s Plymouth two-story, 5" is plenty.

6-inch K-style gutter handles roughly 7,400 square feet of roof area. I go to 6" when:

The roof is over 4,000 square feet
The pitch is steep and the runs are short — water concentrates at the downspouts and overshoots a 5"
Heavy tree cover means partial blockage is a given and you want headroom
The home's architecture supports the visible difference (a lot of Edina and Wayzata homes look better with a 6" line)

6" runs about 20 to 30 percent more per linear foot installed than 5". Most of my Eden Prairie and Plymouth quotes come back at 5". Most of my Edina and Wayzata quotes come back at 6". That's the pattern — it tracks with roof size and architecture.

Aluminum Gutter Cost — Twin Cities 2026 Pricing

Here's what I'm quoting in May 2026 across the Twin Cities. These are installed numbers — material, labor, hangers, downspouts, tear-off, cleanup, the whole job.

	5" K-style	6" K-style	5" Half-Round	6" Half-Round
Per linear foot installed	$7–$10	$10–$14	$12–$18	$16–$22
150 LF typical home	$1,050–$1,500	$1,500–$2,100	$1,800–$2,700	$2,400–$3,300
250 LF larger home	$1,750–$2,500	$2,500–$3,500	$3,000–$4,500	$4,000–$5,500
Heavy-gauge 0.032" upgrade	+15%	+15%	+20%	+20%
Mitered corners	$40–$60 each	$50–$75 each	$60–$90 each	$75–$110 each

We quote per scope, not per fitting. The range above is the total installed scope. What's in that scope:

Tear-off and disposal of existing gutter
5" or 6" seamless aluminum, factory-painted Kynar, your color
Hidden hangers spaced every 24" with stainless steel screws into the fascia
Downspouts and elbows in matching color, properly outletted
Splash blocks at downspout discharge points
Final walk with the homeowner to confirm pitch and discharge

You get a written quote within 48 hours of the measurement visit. One number per scope, scope items listed line by line so you know exactly what's included.

Aluminum Gutter Colors

The 7 colors I sell most in the Twin Cities (all factory-painted Kynar):

White — most common, brightens the fascia, hides nothing if the soffit is dirty
Almond / Buckskin — softer than white, plays well with cream or beige siding
Royal Brown / Musket Brown — pairs with most brown trim packages
Black — modern, popular on new builds and contemporary remodels; reads cleanest on white-house-black-trim
Pewter / Wicker — the gray family, works with almost any siding
Forest Green — traditional, still requested on older homes
Custom colors — available with a longer lead time, usually 3 to 4 weeks

I always pull color samples to the house and hold them against your trim, fascia, and siding in actual daylight. Showroom lighting lies. Sun lighting tells the truth. Don't pick a color off a website screen — make your contractor bring you the chip.

Aluminum Gutter Lifespan in Minnesota

A well-installed aluminum gutter on a Twin Cities home should give you 25 to 35 years before it's time to think about replacement. I've pulled off 30-year-old aluminum that was still structurally sound — just dented from decades of ladders. I've also pulled off 8-year-old aluminum that was wrecked because of how it was hung.

What ends a gutter's life early:

Ice dams. Heavy ice loads pull gutters loose from the fascia. North-facing roofs and badly-ventilated attics are the usual suspects. Here's the part most contractors won't say out loud: if your gutters keep failing from ice, the gutter isn't your problem. Your attic insulation or ventilation is. We can hang you brand-new aluminum tomorrow and it'll fail the same way next winter unless we deal with the ice dam at the source. I'll tell you that on the first visit, not after you've paid for the second gutter.

Ladder damage. Cleaning ladders crush the lip of the gutter over time. A ladder stabilizer (the rubber-tipped V-bar that bolts to the ladder) is under $40 online. Use one. Tell whoever cleans your gutters to use one.

Improper pitch. Aluminum needs a slight slope toward the downspouts — about 1/4" of drop per 10 linear feet. Flat-hung gutter holds standing water. Standing water freezes in winter. Frozen water expands and pops the corner miters. This is the single most common reason for premature gutter failure I see on homes installed by the cheapest bidder.

Detachment from rotted fascia. Hidden hangers anchor to your fascia board. If the fascia is rotten, the screws have nothing to grab. Fix the fascia first. Then hang the gutter. I won't hang aluminum on rotten wood — it's a callback waiting to happen.

If you want the broader picture of how we scope gutter projects against the rest of the exterior, that's all on the gutter installation service page.

Aluminum vs Copper vs Steel vs Vinyl

Once a year someone asks me about copper. Once every couple years someone asks about steel. Here's the comparison:

	Aluminum	Copper	Steel	Vinyl
Cost per LF installed	$7–$14	$25–$45	$9–$16	$4–$7
Lifespan	25–35 years	50–100 years	20–30 years	10–20 years
Maintenance	Low	Low (patinas)	Moderate (rusts at scratches)	Low
Best for	Most homes	Historic / high-end restoration	Industrial / commercial	Budget
Cold-climate performance	Good	Excellent	Good	Goes brittle

For 95 percent of Twin Cities homes, aluminum is the right answer. Copper is gorgeous and lasts forever, but it costs three to five times what aluminum does. I install it on the occasional Lake Minnetonka restoration where the budget supports it. Steel is overkill for most residential and rusts at any scratch. Vinyl I won't install on Minnesota homes — it goes brittle at -20°F and cracks. We had a stretch in January 2024 where it hit -28°F. Vinyl gutter does not survive that.

Gutter Guards: Worth It or Not?

This is the second-most-common question I get, right behind 5" vs 6".

The three gutter guard systems I install:

MasterShield (micro-mesh). Stainless steel micro-mesh on an aluminum frame. Blocks debris down to roof shingle granules. Lifetime transferable warranty. Roughly $14 to $22 per linear foot installed — so a 150 LF home is $2,100 to $3,300 on top of the gutter itself.

KleanGutter (micro-mesh). Same concept as MasterShield, slightly less expensive, slightly shorter warranty. Roughly $11 to $18 per linear foot installed.

LeafFilter (micro-mesh, the one you've seen on TV). Heavily marketed national brand. Costs more than the alternatives ($18 to $30 per linear foot) without measurable performance improvement in my experience. I wrote a full breakdown on this in MasterShield vs LeafFilter vs KleanGutter if you want to go deep.

Are guards worth it? Honest answer:

Heavily-treed lots (oak, maple, ash canopy): Yes. The cost pays back in 8 to 12 years of avoided cleanings and avoided overflow damage.
Open lots with limited tree cover: The math gets harder. Two annual cleanings at $150 to $250 each is $300 to $500 a year. $2,500 in guards is 5 to 8 years of cleanings. Some homeowners come out ahead with cleaning. Some prefer the convenience of guards. Either answer is defensible.

I won't push guards on you if your lot doesn't justify them. If three contractors are all pushing guards as a default add-on, that's a sign — they're making margin on the guard, not solving your actual problem.

What I Don't Love About Aluminum Gutter

Every product has tradeoffs. Aluminum has these:

Dents easily. A branch hit, a ladder pivot, a hail strike — aluminum dents. Steel and copper don't dent as easily. If your house sits under a big oak canopy and you get debris falls, expect cosmetic dents over the life of the gutter. They don't affect function, but they're real.

Paint can fade on cheap coil. Factory Kynar 500 is fine. The cheaper coil some discount contractors use can chalk and fade in 10 to 15 years. Spec Kynar finish on the quote.

Color match issues across years. If you replace one section in year 12 and the rest in year 25, the new section will be slightly different from the weathered original. This is true of any painted exterior product. Plan around it if you're doing a partial replacement.

Expansion and contraction. Aluminum moves with temperature. Long single runs (60+ feet without a break) need expansion joints or they'll buckle in July and pull apart in February. A lot of contractors skip the joint and you find out about it in year 5.

None of these are deal-breakers. They're just the things I'd want a homeowner to know going in, not after the fact.

Frequently Asked Questions

How much does it cost to install aluminum gutters in Minneapolis?

A typical 150-foot home runs $1,050 to $1,500 for 5" K-style installed. Larger 250-foot homes run $1,750 to $2,500. Going to 6" adds 20 to 30 percent. Half-round adds 50 to 80 percent. These are scope-based numbers — one quote per scope, scope items listed.

Are 6-inch gutters worth the extra cost?

On roofs over 4,000 square feet, yes. On standard 1,500 to 3,500 square foot Twin Cities homes, 5" is plenty unless you've got specific water-volume issues — heavy tree cover, steep pitch, or downspout-limited drainage. 6" also looks better on some architecture, which is a legitimate reason to upgrade even when 5" would work hydraulically.

How long do aluminum gutters last in Minnesota?

25 to 35 years with a proper install and reasonable maintenance. The most common reasons I see for early failure: ice dam damage from poor attic insulation, improper pitch causing standing water, and rotten fascia that won't hold the hangers.

Can aluminum gutters handle ice dams?

Aluminum survives normal ice dam conditions if it's hung properly with hidden hangers into solid fascia. Severe ice dams from inadequate attic insulation or ventilation will eventually damage any gutter material — copper, steel, anything. Fix the attic side first. Don't keep buying gutters.

Do aluminum gutters rust?

No. Aluminum doesn't rust. It can oxidize where the paint gets damaged, but the structural aluminum stays intact and the oxidation actually protects the metal underneath. Steel rusts at any scratch. That's one of aluminum's biggest advantages in a wet climate like ours.

How long does a gutter installation take?

A typical 150 LF Twin Cities home is one day on-site, weather permitting. Larger homes with two-story walkouts, multiple roof lines, or complex corner work run two days. The seamless gutter is run right there on the trailer, so there's no off-site fabrication delay.
