6-Inch Gutters
6″ K-style seamless gutters hold about 40% more water than 5″ and drain through larger 3×4″ downspouts. They’re the right default for larger homes, steep or large roof planes, and light commercial buildings across the KC metro. Roll-formed on site in .032 or .040 aluminum.
The right-size upgrade for a roof that moves real water.
A 5″ gutter is fine on a small, simple roof — but a lot of Kansas City homes have big, steep roof planes that overwhelm it in a summer downpour. Premier Gutters KC installs 6″ K-style seamless aluminum that catches more, drains faster, and clogs less, so water ends up in the downspout instead of over the edge and against your foundation.
About 40% more capacity than 5-inch.
The jump from 5″ to 6″ is bigger than it sounds. The wider trough plus a larger 3×4″ downspout means far more water moves through the system before it can back up and spill.
- ~40% more water capacity than a standard 5″ K-style gutter
- Pairs with 3×4″ downspouts — roughly double the outlet of 2×3″
- Wider mouth catches valley and roof-plane runoff that overshoots 5″
- Clogs less — debris passes through the larger trough and outlet
- Roll-formed seamless on site — .032 standard or .040 heavy gauge
- The workhorse profile for larger homes and light commercial buildings
When to move up from 5-inch to 6-inch.
5″ gutters are the residential default, and on a modest single-story roof they do the job. But 6″ becomes the smarter call when the roof feeds more water into fewer places. In the KC metro we recommend stepping up to 6″ when any of these are true:
Large or steep roof planes
A big or steeply pitched roof sheds water fast. The steeper the slope, the more velocity the runoff carries — and a 5″ gutter can simply be overshot at the edge during a hard rain. The wider 6″ mouth catches it.
Long runs feeding one downspout
When a long gutter run drains to a single downspout, the volume stacks up at the outlet. A 6″ trough plus a 3×4″ downspout keeps that water moving instead of pooling and spilling over the low end.
Valleys dumping into one section
Roof valleys concentrate runoff into a narrow band of gutter. That’s one of the most common overflow points on a 5″ system — and one of the clearest reasons to size up to 6″.
Chronic overflow or clogging now
If your existing 5″ gutters overflow in heavy rain or clog every season, the system is undersized for the roof. Moving to 6″ with larger downspouts usually fixes it.
Light commercial buildings
For retail, office, and smaller industrial buildings, 6″ K-style is the standard commercial workhorse. For very large roofs, low-slope sections, or high-volume runoff, we may step up to 7″ oversized gutters instead — see our 6-inch vs 7-inch comparison to weigh it.
Built to spec, finished to match.
Every 6″ run is roll-formed on site so there are no seams to leak. You choose the gauge and color; we handle the sizing.
6″ K-style seamless
The most common upsized profile — a clean crown-molding face that suits most KC homes and light commercial buildings.
.032 or .040 aluminum
.032 is our standard; .040 heavy gauge is available for high-load, long-run, or commercial applications that need extra rigidity.
3×4″ oversized
The larger outlet moves roughly twice the water of a residential 2×3″ and is a big reason 6″ systems clog far less.
Standard & Kynar 500
White, black, bronze, brown, and mill finish in stock, with custom Kynar 500 colors for brand-matched or upscale projects.
Typical KC 6-Inch Pricing
6″ seamless gutter installation in the KC metro typically runs within the commercial range of $12–$24 per linear foot installed — depending on gauge (.032 vs. .040), downspout count, building height and access, and any removal of the old system.
