Tamko Gutter Replacement Nationwide

Tamko Gutter Replacement: The San Antonio Owner’s Guide

If you have Tamko gutters on your San Antonio home and they’re pulling away, leaking at the seams, or sagging in the middle, replacement typically runs $8 to $14 per linear foot installed, and most homes we service in San Antonio fall between $1,100 and $2,400 total. We keep Tamko-compatible gutter sections, end caps, and drop outlets on our trucks, so we can usually swap failing runs in a single visit. The way most San Antonio homeowners discover the problem: they walk outside after a heavy thunderstorm and see water pouring over the front edge of the gutter instead of out the downspout, or they notice the gutter has pulled loose from the fascia board under the weight of a clogged section.

Before we get into costs and specifics, one thing worth stating plainly: Mercer Roofing Co San Antonio is an independent roofing and gutter contractor. We’re not a Tamko dealer or factory branch. We install and replace Tamko gutter components every week, and we buy them through the same distribution channels Tamko uses, but we answer to you, not to a manufacturer’s warranty department. That matters when something fails. Grant Whitlock, our owner, has spent years on San Antonio roofs, and his rule is simple: if a gutter we install fails within a year, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s in writing on every job.

Quick Answer: What Tamko Gutter Replacement Costs in San Antonio

Replacing Tamko gutters in San Antonio costs between $8 and $14 per linear foot installed for standard 5-inch aluminum K-style sections. For a typical single-story home with 120 to 180 linear feet of gutter, the full replacement lands between $1,100 and $2,400. That price includes tear-off of the old sections, new hangers every 24 inches, sealed end caps, new drop outlets where the gutter meets the downspout, and haul-away of the old material. Seamless replacement runs higher, usually $12 to $18 per linear foot, because it’s formed on-site from coil stock to match your exact fascia run. Gutter replacement is not an emergency service, and we don’t rush it. We schedule it, price it in writing before we start, and we don’t change that number unless we open up the fascia and find rot that has to be addressed first, which we’ll show you a photo of before we touch it.

Which Tamko Models This Applies To

Tamko’s gutter line isn’t as widely known as their shingles, but the company has been supplying aluminum and galvanized gutter systems through roofing distributors for years. The most common Tamko gutter products we see on San Antonio homes are 5-inch and 6-inch K-style aluminum sections in 10-foot lengths, along with Tamko’s matching 2×3-inch and 3×4-inch rectangular downspouts. If you’re trying to identify what you have, look inside the gutter near an end cap. Tamko stamps a small manufacturer code along the interior channel, though on older installs that stamp is often worn or painted over. The more reliable identification is measurement: 5-inch Tamko gutters measure 5 inches across the top opening, 3.5 inches deep, and have the standard K-style ogee profile with two bends on the face. A 6-inch section is wider and deeper, typically used on homes with steep roof pitches or heavy tree coverage like we see in Alamo Heights and Terrell Hills, where oak canopies load gutters faster than most systems can shed.

The parts-buying decision comes down to OEM vs. aftermarket. Tamko-branded gutter sections are manufactured to the same spec as the major national gutter suppliers, but they’re not always in stock at local supply houses in San Antonio, which means longer lead times if you’re ordering replacement pieces for a partial repair. In practice, most gutter contractors, including us, use aftermarket 5-inch or 6-inch K-style sections from American manufacturers like Spectra, Berger, or Senox that match Tamko’s profile and gauge exactly. The key gotcha is gauge: Tamko sells both .027-inch and .032-inch aluminum. The heavier .032 will hold its slope longer, and it’s worth specifying if you’re in a part of San Antonio with frequent hail. Lighter .027 sections dent and deform faster, especially on the north side of a home where hail hits hardest. We’ve replaced plenty of .027 gutters that looked like a drum set after one good March storm.

Signs Your Tamko Gutter Is Failing

• Water spilling over the front edge during rain. This almost always means the gutter slope has flattened out or debris has built up to the point where water can’t reach the downspout. In San Antonio, live oak leaves and roof granules from hail-worn shingles are the usual culprits. If the slope is gone, no amount of cleaning fixes it, and the section needs to be re-pitched or replaced.
• Seams separating or leaking at the joints. Sectional gutters like Tamko’s are joined every 10 feet with a lap seam and sealant. After six to eight years of San Antonio heat, that sealant dries out and cracks. You’ll see water dripping from the seam area or a dark mineral streak down the gutter face right below it.
• Gutter pulling away from the fascia board. The hangers, not the gutter itself, usually fail first. The screws back out of sun-baked fascia wood, or the hanger clips lose their grip. A gutter hanging by one end is a fall hazard and will tear the fascia when it goes.
• Visible sag or standing water in the middle of a run. If you can see a dip from the ground, the slope has failed across multiple hangers. Standing water in San Antonio is worse than in most climates because our mosquito season runs nearly year-round, and stagnant gutter water is exactly where they breed.
• Downspout seams splitting or the outlet detaching. Tamko downspouts attach to the gutter through a drop outlet, and that connection takes a beating when the gutter is holding water or when someone leans a ladder against it. If the outlet separates, water runs straight down the exterior wall and into the foundation soil.

Replacement Cost & What’s Included

Let’s talk real numbers for San Antonio. For a standard single-story home with 140 to 160 linear feet of 5-inch Tamko gutter replacement, you’re looking at $1,100 to $2,000 installed. A two-story home with 200-plus linear feet and 6-inch sections usually lands between $2,400 and $3,600. Steeper roofs, second-story work, and homes in neighborhoods like Alamo Heights where we often work around mature trees and tight lot lines can push the number higher because access is slower and safety setup takes more time. Every quote we write in San Antonio is line-itemed: materials, labor, tear-off and haul-away, and any fascia repair that gets uncovered during the job. You get that price in writing before any work starts, and it doesn’t change unless we find hidden rot behind the gutter and you approve the additional work first.

What’s included: removal of the old gutter and hangers, new hidden hangers or bracket hangers every 24 inches, sealed end caps, new drop outlets, reconnection of existing downspouts, and a written 365-day guarantee on the whole job. We’re licensed and insured, and every technician who shows up at your door is background-checked, identity-verified, and photo-badged under the Threshold Verified standard. You’ll get the technician’s name and photo sent to you before they arrive, so you know exactly who’s walking up your driveway.

DIY or Call Us?

Gutter replacement isn’t the most dangerous job in home repair, but it’s not harmless either. The risk calculus changes with ladder height, and most gutter work in San Antonio happens at 10 to 20 feet off the ground, often on uneven terrain around the foundation. If you’re comfortable on a ladder and you have a level, you can diagnose your own slope problems: put a level on the gutter and check whether the bubble sits toward the downspout. If it doesn’t, the section is pitched wrong. What you shouldn’t try to fix yourself is a gutter that has torn away from the fascia, because that usually means the fascia wood behind it is compromised, and the repair involves more than screwing a bracket back in. Same goes for any second-story section. A fall from a two-story gutter line is a hospital trip, and it’s not worth the $200 you’d save on labor. If the job looks bigger than a simple end cap or a loose hanger, call us at (254) 276-4369 and we’ll give you a straight written estimate.
