Seamless Gutter Installation in Texas: Cut On Site, Sized to Your Roof

Compare 5-inch vs 6-inch and full gutter costs →

The gutters at the home-improvement store come in 10-foot sections you snap together, and every joint you add is one more place water can get behind your fascia. Seamless gutters solve that at the source.

A seamless gutter is formed from a single continuous coil of aluminum, fed through a roll-forming machine parked at your house and cut to the exact length of each run. The only seams left are at the corners, where we lap and seal the miters, and at the downspout outlets, far fewer places for a leak to start, and a cleaner line along your roof edge.

Having a roofer hang them, rather than a general handyman, matters because your gutters are part of your roof's edge, not a bolt-on accessory. They tie into your drip edge and fascia, and they have to carry the exact volume of water your roof throws at them, which is why we size the gutter and the downspouts to that load and make the two work as one system.

A seamless gutter is made on your driveway, run to the exact length of your fascia in one continuous piece. The only seams are at the corners and the downspout outlets — and every seam is a future leak. A sectional gutter is nothing but seams. We roll it, hang it to the right pitch, and space the hangers for a Texas downpour, not a drizzle.

Most standard Texas homes do well with 5-inch seamless aluminum K-style gutters. Step up to 6-inch when your roof is steep, large, tile, or metal, or when you have watched a 5-inch gutter sheet water over its edge in a hard rain. A 6-inch K-style carries roughly 40% more water, which is what a fast-draining roof needs to keep the overflow off your fascia.

The most common gutter mistake isn't a bad install. It's a gutter that was never big enough for the roof draining into it. Sizing is the whole game.

A steep or large roof throws water at the eave fast, and a metal or tile roof sheds it faster still. A gutter can only take so much before it overflows at the fascia, exactly where you never want standing water. So we walk your roofline before we quote and check three things:

• Your roof's pitch: the steeper it is, the faster water reaches the eave, and the more capacity you need.
• The square footage draining to each run: the more roof feeding one gutter, the bigger that gutter has to be.
• The roof material: a slick metal or tile surface delivers water to the eave faster than shingles, which often tips the call toward 6-inch.

We install aluminum in the K-style profile as our standard because it carries the most water for the price, won't rust like steel, and won't turn brittle and crack in the heat like vinyl. The color is baked on at the factory, so we match it to your trim and it holds that color under sustained Texas UV instead of chalking out in a few summers.

It is easy to treat gutters as the least important thing on the house. The homeowners who do are the ones who end up paying for it downstream.

When runoff dumps against your foundation instead of draining away, Texas clay soil swells and shrinks with every wet-dry cycle, and that movement is one of the most common causes of the foundation cracks and slab problems you never want to see. Working gutters, sized right and drained well away from the house, are one of the cheapest forms of insurance you can buy against a five-figure foundation repair. That is the real job a gutter does: not decoration, water management.

Gutters are the least glamorous thing we install and one of the most important. The roof sheds the water; the gutters decide where it goes. Get that wrong and you're not looking at a roof problem — you're looking at a foundation problem.

Seamless gutter installation in Texas runs $11 to $12 per linear foot for 5-inch aluminum and $13 to $15.50 for 6-inch, installed with hidden hangers, sealed miters, and downspouts. A typical single-story home needs about 150 to 200 linear feet of gutter.

Your gutters are priced by the linear foot, the length of roof edge they cover, not by the square foot the way your roof is. That catches most homeowners off guard.

Updated August 2026. Texas residential pricing, per linear foot (never per square foot). Every install includes hidden hangers, sealed miters, downspouts, and a full flow test.

At about 150 to 200 feet, a typical single-story home lands roughly between $1,700 and $3,500, 5-inch on simple rooflines at the low end, 6-inch on longer, more complex homes at the high end. Because gutters follow your roof edge and not the roof area, a real number comes from measuring your house, not a formula.

No pressure, no guesswork. Here is the whole thing in three steps.

1. You book a free measure. We come out, measure every run, check the fascia and soffit behind the old gutters, and talk through 5-inch versus 6-inch for your roof.
2. We send a written estimate. You get the footage, the system, the downspout count, and a flat price in writing, usually within a day or two. Nothing is verbal.
3. You decide, and we install, usually in a day. Most homes are measured, formed on site, hung, flow-tested, and cleaned up in a single day, and the work carries our workmanship warranty.

Here is what actually happens on install day. We repair any rotted fascia first, because new gutters on bad wood is money wasted. We roll-form each run on site, then hang it on hidden brackets fastened into solid wood, spaced tight enough to hold a full gutter in a downpour.

From there it comes down to drainage. We set the pitch at about a quarter-inch of fall per 10 feet so water runs to the outlets instead of standing, and we place downspouts where your water load calls for them (a rule of thumb is one for every 30 to 40 feet of run), routed to carry water well away from your foundation. Then we run water through the whole system to confirm it drains clean, and we haul off every scrap under our Clean Site Promise™.

One more timing note: the smartest moment to replace tired gutters is when you're already replacing the roof. The drip edge, fascia, and gutter all live on the same roof edge, so doing them together means one mobilization, one clean detail, and no seam where old gutter meets new roof. If a roof replacement is on your horizon, fold the gutters into it.

You cannot truly DIY seamless gutters, because "seamless" means the runs are roll-formed to length by a machine on site. A rented sectional kit from the store is a different, snap-together product with a joint every 10 feet. Even setting those aside, the pitch, hanger spacing, and downspout sizing are what actually make gutters work, and getting any of them wrong sends water over the edge or back toward your fascia. On a two-story home, the ladder work alone is a real hazard.

Straight answer: not really, and it's worth understanding why before you rent anything.

The roll-forming machine and coil stock that fabricate a seamless run aren't things a homeowner buys for one job. What you can rent is a sectional kit, and every seam you snap together is a future leak. The money you'd save rarely survives the first overflow that soaks the wood behind it.

Straight answer: for some jobs we're not the cheapest call, and we'd rather tell you that here.

We're a great fit if you:

• Want the gutters sized to your actual roof, not a one-size default
• Want seamless runs, sealed miters, and the fascia checked before we hang anything
• Want a written scope and a flat price before work starts
• Want the install to carry a real workmanship warranty

We're probably not the right fit if you:

• Just need a short section patched for under our minimum scope
• Want snap-together sections from the store hung as cheaply as possible
• Are choosing purely on the lowest number
