Gutters & Gutter Guards across Missouri, Kansas, Illinois, Indiana and Kentucky
John Beal Roofing has handled gutter work for Midwest families for decades. We are family-owned, BBB Torch Award recognized, and every installation carries a lifetime workmanship warranty. Someone answers the phone 24 hours a day — nights, weekends and holidays included, which is exactly when roofs decide to fail.
Gutter guards and seamless runs for St. Louis homes are installed by our own crews; read more on St. Louis gutter service.
Every inspection is free, photographed slope by slope, and written up with an itemized price whether or not you hire us. Pick your city below for the local crew, the local storm history and the direct line to the office that covers you.
What gutters actually do for your house
A gutter system is not trim. It is the drainage system that decides where several thousand gallons of roof runoff go every year. An inch of rain on a 2,000 square foot roof puts roughly 1,200 gallons over the edge, and a gutter's whole job is to move that water away from the one place it does the most damage — the ground against your foundation.
When the system fails, the damage shows up everywhere except the gutter: water pooling against the foundation and finding its way into the basement, eroded landscaping and mulch washed into the yard, rotted fascia and soffit, saturated siding, peeling paint, split driveways and walkways from freeze-thaw, ice dams at the eaves in winter, and a wet crawlspace that turns into a mold and insect problem. Gutters are one of the cheapest things on a house to maintain and one of the most expensive to ignore.
Seamless gutters versus sectional
Seamless gutters are formed on site from a continuous coil, cut to the exact length of each run, so the only joints in the system are at corners, end caps and outlets. Sectional gutters are pre-cut lengths from a big-box store joined every ten feet with a sealed connector.
Every seam is a future leak. Sealant at a joint has a service life measured in a few years; the metal has a service life measured in decades. That is the whole argument, and it is why we install seamless: fewer joints, fewer failure points, a cleaner line on the fascia, and no staining streaks running down the siding under every connector.
Sizes: 5-inch, 6-inch, and why it matters
5-inch K-style is the standard residential gutter and it handles most homes with typical roof area and pitch. 6-inch K-style moves roughly 40 percent more water and pairs with 3x4 downspouts instead of 2x3.
Bigger is not automatically better, but 6-inch is the right call on: large or steep roofs that dump water fast, long runs with few downspouts, roofs with big valleys that concentrate flow into one section of gutter, and homes that have overflowed a 5-inch system before. Undersized gutters overflow in exactly the storms that matter, and overflow at the eave is what rots fascia. We size the system to the roof area and pitch draining into it rather than defaulting to whatever is on the truck.
Materials: aluminum, steel, copper
Aluminum is the standard for good reason: it will not rust, it is light, it comes in a wide range of baked-on factory colors, and .032 gauge aluminum — heavier than the .027 commonly installed — holds its shape against ladders, ice and debris. Galvanized steel is stronger on impact and a fit for commercial work or homes with heavy tree load, but it will eventually rust at cut edges and scratches. Copper is the premium option: it lasts generations, needs no paint, and develops the patina people install it for — appropriate on historic homes and worth the cost only where the look matters.
Color is baked on at the mill rather than painted on site, so it does not peel, and it is matched to fascia, trim or roof depending on whether you want the gutter to disappear or to read as a line.
Downspouts, outlets and where the water goes
The gutter is only half the system. Downspouts move the water down, and their placement and count are what keep a gutter from overflowing. General practice is a downspout for roughly every 30 to 40 feet of run, more where valleys concentrate flow, and 2x3 on 5-inch systems or 3x4 on 6-inch.
Where the water lands matters just as much. A downspout that dumps at the foundation has moved the problem four feet, not solved it. We extend discharge away from the house with elbows and extensions, splash blocks, or underground drain lines to daylight where the grade allows. And the grade itself has to slope away from the house — a perfect gutter system over negative grade still puts water in the basement.
Gutter guards: what works and what does not
Gutter guards reduce cleaning; nothing eliminates it, and any company promising you will never clean your gutters again is selling you something. What they genuinely do is keep the system from clogging with leaves and roof debris, which is where most gutter failure starts.
- Micro-mesh — stainless steel mesh over a rigid frame. The best-performing style for fine debris like pine needles, shingle grit and seed pods. Top-tier option.
- Perforated aluminum — solid panels with punched holes. Good on leaves, can blind over with fine debris and pollen.
- Reverse curve / surface tension — water wraps the nose into a slot. Effective on leaves; can overshoot in heavy downpours and struggles with pine needles.
- Foam inserts — cheap, easy, and they collect seeds and grow debris inside the gutter. We do not recommend them.
- Plastic screens — budget option, UV-brittle, blow out in wind.
One caution: a guard installed under the shingles improperly can lift the first course or void a roofing warranty. Guards belong on a gutter that is correctly pitched and secured — putting a guard on a sagging gutter just hides the sag.
Fascia, soffit and the rot nobody sees coming
The fascia is the board the gutter hangs on. The soffit is the underside panel that also carries your attic's intake ventilation. When a gutter overflows or a back-pitched run holds standing water, the fascia behind it soaks, and rotted fascia will not hold a gutter no matter how good the gutter is. That is why a gutter that keeps pulling loose is usually a fascia problem wearing a gutter costume.
Soffit damage costs you twice: water stains and rots the panel, and blocked or damaged soffit vents choke the intake air your roof needs. A roof with exhaust at the ridge and no intake at the soffit pulls conditioned air out of your house and bakes the shingles from underneath. We install and repair roofing, gutters, soffit, fascia and siding with our own crews, so the whole edge of the roof gets addressed as one assembly instead of three trades pointing at each other.
Ice dams, winter and gutters
A common myth is that gutters cause ice dams. They do not. Ice dams are caused by heat escaping into the attic, which melts snow high on the roof; the meltwater runs down to the cold eave and refreezes. Gutters simply give the ice a place to build, and then take the abuse — a full gutter of ice weighs enough to pull fasteners, bend the trough and tear fascia.
The real fixes are attic air sealing, insulation and balanced ventilation, plus ice-and-water shield membrane at the eaves when the roof is replaced. What gutters need in winter is to be clean going into the season, correctly pitched so nothing stands, secured with hidden hangers rather than old spike-and-ferrule, and free-draining at the downspout so meltwater has somewhere to go instead of backing up.
Storm and hail damage to gutters — and your claim
Hail dents gutters, downspouts, and the soft metal on the roof, and those dents are one of the first things an adjuster reads to confirm a hail event even happened. Wind tears gutters loose, bends them, and rips downspouts off the wall.
Here is what homeowners miss: when a storm damages the roof, the gutters are usually part of the same claim. Dented gutters and downspouts, damaged fascia wrap and torn screens all belong in the scope. Because we roof and install gutters with our own crews, one inspection documents the entire exterior and one scope goes to your adjuster instead of three contractors on three schedules. See storm damage and roof insurance claims.
Signs your gutters need repair or replacement
- Water spilling over the edge in a normal rain — clogged, undersized or back-pitched
- Sagging or pulling away from the fascia, or visible gaps behind the gutter
- Peeling paint or rust streaks on the siding under a seam
- Standing water in the trough after rain stops — a pitch problem
- Leaks at corners, end caps and seams, or re-caulked joints that keep failing
- Nail or spike heads backing out of the fascia
- Eroded mulch, trenched soil or splash marks along the foundation
- Basement or crawlspace moisture after storms
- Plants growing in the gutter — that is soil, and soil holds water
- Dents, dings and bent sections after hail or wind
- Soft, dark or spongy fascia board behind the gutter
- Icicles and ice buildup every winter in the same spot
Repair, or replace the whole system?
Repair makes sense for a failure in one place on a system that is otherwise sound: re-pitching a run, replacing a section, resealing a corner, rehanging a length with new hidden hangers, replacing a downspout, or swapping rotted fascia behind an otherwise good gutter.
Replacement makes sense when the problems are spread out: multiple failing seams on old sectional gutters, widespread hail denting, gutters that are undersized for the roof and overflow every real storm, and any system hanging on old spike-and-ferrule fasteners that has already pulled loose more than once. As with roofs, the honest test is whether the repair holds for years or just until the next storm.
How the installation works, and how long it takes
- Free inspection and measurement — roof area, pitch, existing downspout locations, fascia condition.
- Sizing and color selection, with fascia and trim matched.
- Tear-off of the old system and disposal.
- Fascia repair where the board will not hold a fastener.
- Seamless runs formed on site from continuous coil, cut to your exact lengths.
- Hanging with hidden hangers screwed into solid wood, pitched for drainage — roughly a quarter inch of fall for every 10 feet toward the outlet.
- Corners, end caps and outlets sealed.
- Downspouts set and discharge extended away from the foundation.
- Gutter guards if you opted for them.
- Water test, cleanup and walkthrough.
Most homes are a single-day job. Larger homes, steep or three-story runs, fascia replacement or underground drainage can extend it.
Maintenance that keeps a gutter system working
- Clean twice a year at minimum — late spring and after leaf drop. Add a cleaning if you have pines or heavy tree cover.
- Check after major storms for dents, loose sections and clogged outlets.
- Flush the downspouts, not just the trough — a clear gutter into a clogged downspout still overflows.
- Watch the water in a rain. Five minutes of watching in a downpour tells you more than an inspection in dry weather.
- Keep discharge extensions in place and pointed away from the house.
- Trim branches back off the roof and gutter line.
- Never lean a ladder against the gutter — it bends the trough and breaks the pitch.
- Watch the fascia, since that is where a small gutter problem turns into a carpentry bill.
Who installs them, and who stands behind them
Gutters are sold by everyone from national franchises with a one-product pitch to a guy with a brake on a trailer. What we bring is the same thing we bring to a roof: our own in-house crews, a written itemized scope before work starts, a free inspection, and a company that has been answering its phone in this region since 1947.
We are licensed and insured (License # 104.011957/105.007037), BBB Accredited, a BBB Torch Award for Ethics recipient, family-owned through three generations, with more than 50,000 satisfied customers across ten local markets in Missouri, Kansas, Illinois, Indiana and Kentucky, and 24/7 emergency service. Because we also install the roof, siding, soffit and fascia, the edge of your roof is one crew's responsibility rather than a seam between trades.
Gutter questions, answered
Tap any question to open it.
How much do new gutters cost?
It depends on total linear footage, 5-inch versus 6-inch, material and gauge, the number of downspouts and corners, how many stories, whether fascia has to be repaired first, and whether you add gutter guards. Anyone quoting gutters without measuring the house is guessing. Our inspection and written itemized estimate are free.
What are seamless gutters and are they better?
Seamless gutters are formed on site from continuous coil and cut to the exact length of each run, so the only joints are at corners, end caps and outlets. Sectional gutters are joined every ten feet, and every one of those sealed joints is a future leak — which is why we install seamless.
Should I get 5-inch or 6-inch gutters?
5-inch K-style handles most homes. 6-inch moves about 40 percent more water and pairs with larger 3x4 downspouts — the right call on large or steep roofs, long runs with few downspouts, roofs with big valleys concentrating flow, or any home that has overflowed a 5-inch system before.
How long do gutters last?
Aluminum seamless gutters commonly last 20 years or more, galvanized steel somewhat less before rust appears at cut edges and scratches, and copper can last generations. Fasteners, pitch and cleaning discipline matter as much as the metal.
Do gutter guards really work?
Good ones dramatically reduce clogging; none eliminate cleaning, and any company promising you will never clean your gutters again is overselling. Micro-mesh stainless performs best on fine debris like pine needles and shingle grit. We do not recommend foam inserts, which collect seeds and hold debris inside the trough.
Which gutter guard is best for pine needles?
Micro-mesh stainless steel over a rigid frame. Perforated panels and reverse-curve systems both struggle with needles, and screens and foam are not a real answer in heavy pine.
How often should gutters be cleaned?
Twice a year minimum — late spring and after leaf drop — plus a check after major storms. Heavy tree cover or pines means more often. Flush the downspouts too, because a clear trough feeding a clogged downspout still overflows.
Why are my gutters overflowing even though they are clean?
Usually one of three things: the gutter is undersized for the roof area and pitch draining into it, the run is back-pitched or sagging so water stands instead of draining, or there are too few downspouts for the length of the run. Valleys that dump a large roof area into one short section cause it too.
Why do my gutters sag or pull away from the house?
Either the fasteners are old spike-and-ferrule that have worked loose, or — more often — the fascia board behind the gutter has rotted and no longer holds a screw. A gutter that keeps pulling loose is usually a fascia problem, and replacing the gutter without repairing the fascia just repeats it.
Do you repair fascia and soffit?
Yes. We install and repair roofing, gutters, soffit, fascia and siding with our own crews, so the whole roof edge is handled as one assembly. Soffit matters twice over, because it carries the intake ventilation your attic needs.
Can gutters be repaired instead of replaced?
Often, yes — re-pitching a run, replacing a section, resealing a corner, rehanging with hidden hangers, or swapping a downspout. Replacement makes sense when failures are spread across the system, the gutters are undersized, or hail has dented them throughout.
Do gutters cause ice dams?
No. Ice dams are caused by heat escaping into the attic, which melts snow high on the roof; the meltwater refreezes at the cold eave. Gutters just give that ice a place to build and then take the abuse. The real fixes are attic air sealing, insulation, balanced ventilation and ice-and-water shield at the eaves.
Will insurance cover hail-damaged gutters?
Frequently, as part of the same storm claim as the roof. Dented gutters and downspouts, damaged fascia wrap and torn screens belong in the scope — and those dents are one of the first things an adjuster reads to confirm a hail event. One inspection from us documents the whole exterior.
How long does a gutter installation take?
Most homes are a single day. Larger homes, steep or three-story runs, fascia replacement or underground drain lines can extend it into a second day.
Can you match my gutter color to my trim?
Yes. Aluminum comes in a wide range of baked-on factory colors — finished at the mill rather than painted on site, so it does not peel — and we match to fascia, trim or roof depending on whether you want the gutter to disappear or read as a line.
Where should downspouts discharge?
Away from the foundation, never at it. We extend discharge with elbows and extensions, splash blocks, or underground drain lines to daylight where the grade allows. A downspout that dumps at the foundation has moved the problem a few feet, not solved it.
How many downspouts does a house need?
Roughly one for every 30 to 40 feet of gutter run, with more where valleys concentrate flow. 2x3 downspouts pair with 5-inch gutters, 3x4 with 6-inch. Too few downspouts overflows a perfectly good gutter.
What are gutters made of?
Aluminum is the standard — rust-proof, light, factory-colored, and best in a heavier .032 gauge. Galvanized steel is stronger on impact but eventually rusts at cut edges. Copper is the premium choice for historic and high-end homes and lasts generations.
Should gutters be replaced when I replace my roof?
It is the natural time to do it. The crew is already there, the edge details — drip edge, ice-and-water shield, fascia — are exposed and can be done correctly as one assembly, and old gutters get bent during a tear-off anyway. If your gutters are sound we will tell you so.
Do I need gutters on the whole house?
Not always. Gutters matter most above doors and walkways, on any elevation where runoff lands near the foundation, and wherever grade slopes toward the house. Some short or well-graded elevations genuinely do not need them, and we will say so rather than selling footage you do not need.

Seamless gutter installation near you
Looking for gutter installation companies near you? John Beal Roofing installs seamless gutters across all of our markets, from Greater St. Louis and Kansas City to Springfield, Columbia, Jefferson City, Lake of the Ozarks, Farmington, Cape Girardeau, Southern Illinois, Paducah and Indianapolis.
Why seamless? Sectional gutters are joined every 10 feet or so, and every joint is a place for a leak to start. Seamless gutters are formed on site to the exact length of each run, so the only joints are at the corners and downspouts. Fewer seams means fewer drips, less maintenance and a cleaner roofline.
What a gutter install includes
- Measuring each run and checking the fascia for rot before anything goes up.
- Gutters formed to length on site and hung with the correct pitch toward the downspouts.
- Downspouts placed to move water away from the foundation.
- Optional gutter guards for homes under heavy tree cover.
Gutters and your roof work together
Clogged or undersized gutters back water up under the roof edge and into the fascia and soffit. When we inspect a roof we check the gutters too, and when we replace a roof we can replace the gutters in the same project.
