Seamless or sectional?
Sectional gutter is joined every few feet and every joint is a future leak. Seamless is rolled to the length of the run on site. It's the single biggest difference in how long a gutter stays watertight.
Seamless gutters and downspouts, sized and pitched to actually move Missouri rain away from your foundation. Scoped alongside your roof, or on their own — and available on their own if the roof is fine.

A roof’s whole job is moving water. The gutters are the last handoff in that chain, and they are the part homeowners think about least — usually right up until water is running down the siding or standing against the foundation.
Which is the honest reason to scope them together with a replacement. Putting a new roof over gutters that can’t keep up with it is finishing three quarters of the job.
Doing the roof and the gutters at the same time also means the drip edge, the fascia and the gutter line get set up together — see what a replacement includes.
Every run of eave, every corner, and where the downspouts can sensibly drop without dumping water somewhere new.
Formed to length on site from a single coil, so the only joints are at corners and outlets instead of every few feet.
Fastened to sound fascia and pitched toward the outlets, so the water actually leaves rather than sitting in the trough.
Downspouts and extensions placed so the water is discharged clear of the foundation, not into the flowerbed against it.

Gutter is only as sound as the board it hangs on. If the fascia behind the old gutter has gone soft, that needs saying out loud before new gutter goes over it — not discovered afterwards.
New gutter that discharges two feet from the foundation has moved the problem, not solved it. Ask where the downspouts land and how far the water gets from the house.
Yes. New gutters come with a roof replacement from Sobczak Exteriors. It isn't an upsell brought out at the table after you've already agreed to the roof.
Seamless gutter is rolled to length on site from a single coil, so the only joints on a run are at the corners and the outlets. Sectional gutter is joined every few feet, and every one of those joints is a place that can eventually leak.
A gutter has to carry the water a roof sheds in a heavy Missouri downpour, and it has to fall enough toward the downspouts to actually drain. Undersized or badly pitched gutter overflows in exactly the storm you needed it for, and that water goes straight down against the foundation.
Yes — gutters and downspouts on their own are fine. Call and it gets priced the same way as everything else: measured at the house, written down.
Free estimate, written price — and if you’re replacing the roof, the gutters get scoped in the same visit.
