Owens Corning Gutter Replacement Nationwide

Owens Corning Gutter Replacement: The San Antonio Owner’s Guide

Owens Corning gutter replacement in San Antonio typically runs $8 – $14 per linear foot installed, with most standard single-story homes landing between $1,200 and $2,600 for a full gutter run. We stock Owens Corning-compatible gutter systems and components on our trucks, and most replacements are completed same-day once we’re on site. The way most San Antonio homeowners discover they need this is unglamorous: they notice water spilling over the gutter edge during a downpour, or they find the gutter pulling away from the fascia with visible sag between hangers.

Owens Corning doesn’t actually manufacture gutters under their own brand the way they do shingles. What they do manufacture is the roof edge and drip edge systems that tie into them, plus the underlayment and shingle lines that direct water into your gutters. When a San Antonio homeowner searches for “Owens Corning gutter replacement,” what they usually have is either gutters that were installed alongside an Owens Corning roof system and are now failing, or they want gutters that integrate properly with their Owens Corning roof and its warranty requirements. That distinction matters, and we’ll walk through it below.

Key takeaways:

• Owens Corning-branded gutter components are limited to edge metals and drainage accessories; the gutters themselves are typically a compatible third-party system matched to your roof.
• Our San Antonio gutter replacements run from roughly $8 to $14 per linear foot, and we put that price in writing before any work starts.
• Every replacement carries our 365-Day Done Right Promise, in writing, at no extra cost.

Which Owens Corning Models This Applies To

The roof-to-gutter connection on an Owens Corning system comes down to what’s called the drip edge, which is the metal strip that guides water off the roof deck and into the gutter trough. Owens Corning specifies drip edge profiles that overhang the gutter by a minimum of 1/4 inch. If the previous installer set the gutter too tight to the fascia, or if the drip edge was bent, cut short, or omitted entirely on a re-roof, water will hug the fascia board and run behind the gutter. That’s a compatibility failure, not just a gutter failure. We see it constantly on San Antonio homes built in the early 2000s, where original gutters were hung before the Owens Corning re-roof and never repositioned afterward.

When we talk about replacing an “Owens Corning gutter,” the field is really this: 5-inch K-style aluminum gutters matched to the roof’s Owens Corning shingle profile, plus downspouts sized at 2×3 inches for standard runs. Most San Antonio homes take 5K gutters unless the roof pitch is steep or the overhang is unusually deep, in which case 6-inch half-round or 6K profiles do the job. The gotcha to check: if you have Owens Corning Duration or TruDefinition Duration shingles, the shingle overhang into the gutter should be roughly 3/4 inch. If a previous contractor left an inch or more, the shingles wick water backward instead of dripping clean. A proper gutter replacement should include correcting that overhang, not just swapping the metal.

For materials, we install factory-formed seamless aluminum using a portable gutter machine on-site, because that eliminates the seam leaks that plague sectioned gutters over time. The aluminum we run is .027-gauge standard, with .032-gauge available for homes with heavy oak canopy or frequent hail. As an independent San Antonio roofing and gutter contractor, we’re not affiliated with Owens Corning directly, but we install and repair using Owens Corning roofing materials and we understand exactly how their systems need to drain. We also work regularly with GAF and CertainTeed systems, so if your roof isn’t Owens Corning, the same gutter expertise applies.

Signs Your Owens Corning Gutter Replacement Is Failing

• Water spilling over the front edge during moderate rain. This usually means the gutter pitch has flattened over time, or the downspouts are undersized for the roof area feeding them. San Antonio’s clay-heavy soil settles, and fascia boards move with it, which can invert the slope over a five-year span.
• Gutter pulling away from the fascia with visible daylight behind the bracket. The spike-and-ferrule hangers used on older homes rust at the spike head and lose grip. Once the gutter tilts nose-down, every rain event erodes the soil at the foundation line.
• Seams dripping or staining the gutter exterior. Sectioned gutters sealed with caulk will fail at the seams eventually because San Antonio’s heat cycle bakes the sealant brittle. When you see black streaks down the outside face, that’s water and decomposed organic matter leaking through the seam, not just cosmetic dirt.
• Downspouts that pour water at the foundation instead of five feet away. This is a downspout extension or elbow problem, not always a full gutter replacement, but if the downspout itself is rusted through at the elbow connection, you’ll need that section replaced.
• Granule buildup from Owens Corning shingles clogging the gutter trough. All asphalt shingles shed granules, but if you’re seeing heavy granule accumulation within the first five years, that’s a sign your roof is shearing and the gutter is catching the evidence. A gutter replacement won’t fix the roof, but the clog points to where drainage was already failing.

Replacement Cost & What’s Included

For San Antonio, a standard seamless aluminum gutter replacement on a single-story home runs $8 to $14 per linear foot installed, including downspouts, hangers, end caps, and haul-away of the old material. A typical 1,800 to 2,200 square foot home has between 140 and 180 linear feet of gutter, which puts most jobs between $1,200 and $2,600 total. Two-story homes push higher because of ladder time and fall protection setup. If your home has steel or copper gutters now, the replacement price moves up, but those are rare in San Antonio outside custom builds.

What’s included in our number, every time: the gutter material, hidden hangers spaced every 24 inches (not the old spike style), downspouts and elbows, sealant at all joints, and the labor to remove and dispose of the old system. We do not charge extra for the disposal. The price you get in writing before we start is the price on the invoice. No change orders for “unexpected” fascia rot discovered mid-job unless you explicitly approve it first, with the new number in writing before that work begins. That’s how every Crestview Roofing job runs, and it’s part of The Relay Visibility Guarantee: written price, before-and-after photos, live arrival time, and a digital invoice sent by text. Every gutter replacement ends with a quick photo set of the completed runs and downspout terminations so you can see exactly what was done.

On the warranty side, our 365-Day Done Right Promise covers the installation for a full year. If a hanger loosens, a seam drips, or a downspout separates within 365 days, we come back and fix it at no charge. That’s in writing, included with every job, no fine print.

DIY or Call Us?

For a single damaged section or a broken hanger, a homeowner with basic tools can make a temporary fix. Re-securing a loose gutter with a new hidden hanger is an afternoon job if you own a drill and a level. Cleaning out a clogged downspout is straightforward. What’s not a safe DIY job is replacing a full gutter run on anything above a single story, or attempting to re-pitch gutters that have pulled away from a second-story fascia. Ladder work at height, especially on San Antonio homes with limestone ledges under the ladder feet or steep grade changes, is where homeowners get hurt. We treat gutter replacement as a safety-conscious trade: the techs are background-checked, uniformed, and loaded with the proper stabilizers, standoffs, and harness points for two-story work.

If you’re comfortable on a ladder and it’s a five-foot section, go ahead. If it’s a whole run, rusted-through downspouts, or anything two stories up, call us at (361) 209-8857 and we’ll get you a written estimate. You’ll know who’s coming, when they’ll arrive, and exactly what it costs before we start.
