# Commercial Gutters in New Braunfels, TX — Sized to the Roof Source: https://arproofing.com/new-braunfels-commercial-gutters/ Last updated October 2026 New Braunfels, Texas If water is spilling over your gutters, pooling at the base of the building, or finding its way behind the fascia, the problem is almost never the roof membrane — it's drainage that was never sized to the load. Here's how ARP fixes that. ARP installs box and seamless commercial-gauge gutters, scuppers, and internal roof drains on commercial buildings across New Braunfels and Comal County — sized to the roof's actual drainage load, not the cheapest run that fits. Gutter and drainage work is priced per linear foot and per opening, and every project starts with a free roof inspection & estimate.

The point is moving every gallon that lands on your roof away from the building envelope before it undermines the slab, rots the fascia, or backs up under the membrane edge. A gutter that's too small for the roof it serves doesn't fail loudly — it just overflows in the third inch of a Comal County downpour, and you find out when the tenant calls. ARP sizes the system to the roof, not to the price tag. More than 5,000 completed roofing projects across Texas, 300+ five-star reviews, and a decade of commercial work along the I-35 corridor stand behind that discipline. When our team walks your building, we're reading the roof's square footage, its slope, where the water already wants to go, and how many outlets it takes to move that volume without ponding. That's the calculation a lowball bid skips. Gutters are craft work, not a certification play — so we won't dress this page up with a manufacturer badge that doesn't belong on it. What backs your drainage system is commercial-gauge material, correct sizing, and outlets placed where the water actually is — documented before anyone climbs a ladder. ![Roof-edge and parapet drainage on a New Braunfels commercial building — sized and detailed to carry an I-35-corridor downpour off the roof, not pond on it.](https://arproofing.com/_astro/commercial-flat-roof-tpo-membrane-parapet.CclyjRRq_a3E5e.webp) Roof-edge and parapet drainage on a New Braunfels commercial building — sized and detailed to carry an I-35-corridor downpour off the roof, not pond on it. Box Seamless Scuppers ## Box, Seamless, Scuppers, and Drains for Comal County Buildings Commercial drainage isn't one product — it's a system, and the right mix depends on your roof. - **Box gutters (commercial gauge)** — the workhorse for large commercial roofs. Their deep, squared profile carries the highest volume, which is what you want when a wide warehouse or retail roof dumps into a small number of outlets. Heavier gauge than any residential gutter, built to hold up under a full Texas storm load. - **Seamless commercial gutters and downspouts** — formed in continuous runs so there are far fewer joints to open up and leak over time. On standard-length runs, seamless is the lower-maintenance choice; it removes the seams that are the first thing to fail on a sectional gutter. - **Roof scuppers and conductor heads** — the openings that let water leave a roof through the parapet wall, feeding into a conductor head and downspout. On flat and low-slope commercial roofs, scuppers are often doing the real drainage work, and undersized or clogged scuppers are a leading cause of ponding. - **Internal roof drains** — set into the roof field and plumbed through the building, they pull water off the low points on large flat roofs where edge drainage alone can't keep up. Most buildings we assess in New Braunfels and Comal County — from Gruene storefronts to Canyon Lake light-industrial — end up with a combination. The assessment settles which pieces your roof actually needs to move its water, instead of forcing one product onto a roof it doesn't fit. Installed Cost ## What Commercial Gutters Cost in New Braunfels Commercial-gauge box gutters run **$27 to $35 per linear foot** in New Braunfels, and seamless runs **$27 to $32 per linear foot**. Scuppers run **$500 to $1,000 each** and internal roof drains **$900 to $1,800 each** — priced per opening, never per square foot. These are September 2026 New Braunfels figures. Notice the units: gutter runs are priced per linear foot of the run, and scuppers and drains are priced per opening. Nobody quotes commercial gutters by the square foot — if a bid does, it's guessing. | Component | Price | Basis | | --- | --- | --- | | Box gutters & downspouts (commercial gauge) | $27.00–$35.00 / linear ft | per lf of run | | Seamless commercial gutters & downspouts | $27.00–$32.00 / linear ft | per lf of run | | Gutter repair / reseal (commercial) | $500.00–$1,000.00 | line item, $1,295 job minimum | | Scupper (new install) | $500.00–$1,000.00 | per opening | | Internal roof drain (new install) | $900.00–$1,800.00 | per opening | Your final number moves with four things: total linear footage, the gutter profile and gauge, how many scuppers and drains the roof needs, and the building's height and access.

Get your New Braunfels gutter quote ## What seamless gutters cost in New Braunfels Seamless gutters are priced by the linear foot, not as one flat number — the honest answer is a range until we measure your roofline. Here's what moves your number, and how to get a firm one in writing. How gutters are priced Seamless gutters are priced by the linear foot, not as one flat number. Standard 5-inch aluminum sits in a lower per-foot range; oversized 6-inch systems for steep, large, or metal roofs cost more; and gutter guards add to the total. Your number depends on how many feet of gutter and how many downspouts your home needs. Why we measure first We size the system to the actual roof area feeding each run, not to whatever fit the old fascia — then roll the seamless gutter on-site and put a firm, itemized price in writing. ### Book your free New Braunfels gutter estimate We measure your roofline and hand you a written, itemized price — no guessing off a photo. Honest fit check ## Is ARP the right fit for your New Braunfels project? The best way to judge any New Braunfels contractor — us or anyone else — is to ask for a written scope, ask who your single point of contact is, and ask when the manufacturer warranty gets registered in your name. If a roofer can't answer those three plainly, that's your answer. Yes — we're a match ### A good fit if you - Want a roofer your New Braunfels neighbors have actually used — not a pop-up tent after the last hailstorm. - Want everything documented and in writing, with photos, before any crew gets on the roof. - Plan to stay in your New Braunfels home or hold the property long term. - Had recent hail or wind damage and want it documented correctly for your carrier. [Free Inspection & Estimate →](https://arproofing.com/book/) No — we'll say so up front ### Not the right fit if you - Need a commercial job below our minimum repair scope, or a firm residential repair price over the phone — we quote every repair after an on-roof inspection. - Need someone to start tomorrow with no inspection. - Are choosing purely on the lowest bid, without reading the scope underneath it. - Want a contractor to pay, waive or "take care of" your deductible — a criminal offense in Texas under Business & Commerce Code § 27.02. We'd rather tell you that on the phone than waste a walkthrough.

Commercial-gauge box gutters run $27 to $35 per linear foot and seamless runs $27 to $32 per linear foot. Scuppers run $500 to $1,000 each and internal roof drains $900 to $1,800 each. The total depends on your footage and how many openings the roof needs — see the [commercial gutters guide](https://arproofing.com/commercial-roofing-contractor/commercial-gutters/) for the full pricing picture. ### Box or seamless gutters for my building? Box gutters carry the highest volume, which makes them the choice for large commercial roofs feeding a small number of outlets. Seamless commercial-gauge runs reduce joints and leak points on standard-length runs. ARP sizes the system to the roof's drainage load rather than defaulting to one profile — that's what the assessment settles. ### Do you install scuppers and roof drains, not just gutters? Yes. Scuppers, conductor heads, and internal roof drains are all part of a commercial drainage system, priced per opening and sized to move the roof's water rather than let it back up. On flat and low-slope roofs, the scuppers and drains often do more of the real work than the perimeter gutters. See our [New Braunfels TPO roofing](https://arproofing.com/new-braunfels-tpo-roofing/) page for how drainage ties into a single-ply reroof. ### Can you reuse my existing scuppers on a reroof? Sometimes — but a new roof often needs new drainage to hold its warranty, so we don't assume the old openings still perform. ARP checks the existing scuppers and drains, then itemizes any new ones rather than lowball the bid by leaving them off.
