CertainTeed Gutter Replacement: The Fort Lauderdale Owner’s Guide
If your CertainTeed gutters are pulling away from the fascia, leaking at the seams, or overflowing during a routine South Florida downpour, we can replace them. A typical CertainTeed-compatible gutter replacement in Fort Lauderdale runs $8 to $14 per linear foot installed, which puts most single-story homes between $1,200 and $2,800 depending on the gutter profile and linear footage. We stock common CertainTeed dimensions on our trucks, and most replacements are finished in a single visit.
Most homeowners discover the problem the way you probably just did: they walk outside after a storm, see water dumping over the edge in one spot, and then notice the gutter is either cracked, separated at a joint, or sagging so badly it’s pulling the hangers out of the fascia board. You might also see rust streaks running down from a seam, or find that one section is holding water days after the rain has stopped. That’s a failed slope, not a rain issue.
One thing to know: Mercer Roofing Co Fort Lauderdale is an independent roofing and gutter contractor. We install and replace gutters that are compatible with CertainTeed systems, but we are not affiliated with CertainTeed and do not sell their products directly. What we do is match the gauge, profile, and mounting style of your existing CertainTeed gutter so the replacement blends in, drains correctly, and holds up to Fort Lauderdale’s weather.
Which CertainTeed Models This Applies To
CertainTeed’s gutter line is not as widely known as their shingles, but if you have CertainTeed-branded gutters on a Fort Lauderdale home, you almost certainly have one of two configurations: 5-inch K-style aluminum gutters in a standard residential profile, or 6-inch half-round gutters on older or higher-end coastal properties. The 5-inch K-style is by far the more common of the two in Broward County, and it’s the one we replace most often.
The compatibility gotcha with CertainTeed gutters is not the gutter itself. It’s the mounting hardware and the outlet spacing. CertainTeed’s hanger spacing on their 5-inch K-style system is tighter than what many aftermarket installers use, which means a generic replacement can sag in the exact spots your old one held its line. We match the original hanger spacing when we swap a section so the new run carries water the same way the rest of the system does.
Here’s what matters for matching the part. The color is cosmetic. The gauge is structural. CertainTeed residential gutters are typically .027-gauge aluminum, sometimes thinner on builder-grade installs. If your gutters were installed as part of a new construction package in the last fifteen years, check for a faded manufacturing sticker inside the gutter near a downspout. If it’s gone, we identify the gauge on site with a simple measurement – the difference between .027 and .032 aluminum is visible to the touch if you know what to look for.
On the OEM-vs-aftermarket question: for certain products, there’s a real reason to insist on the original. For 5-inch K-style aluminum gutters, there’s almost never a reason to pay an OEM markup. The aftermarket aluminum we use is the same alloy family, the same profile, and in South Florida’s salt-and-sun climate it actually outperforms some manufacturer-spec material because we spec it thicker at the joints. We also stock replacement parts for GAF and Owens Corning gutter systems, but CertainTeed accounts for most of what we see in the Fort Lauderdale neighborhoods we serve.
Styles & brands we work with






Signs Your CertainTeed Gutter Replacement Is Failing
- Water overflowing at one localized spot during rain. That’s not usually a clog. It’s a slope failure – the gutter has dropped or shifted so that water pools instead of running to the downspout. In Fort Lauderdale, this shows up fast because our afternoon storms dump an inch in twenty minutes.
- Visible separation at a seam or end cap. Aluminum expands and contracts with heat. Over five or six South Florida summers, the sealant at factory seams dries out and the metal opens a small gap. Water finds it and streaks down the fascia board.
- Sagging sections with hangers visibly pulling out of the wood. This is the one to catch early. Once a hanger loses its bite in the fascia, every heavy rain pulls it a little farther out. The gutter follows, and the slope is gone.
- Rust stains or green algae tracks down the outside face of the gutter. CertainTeed aluminum gutters don’t rust, but the screws and brackets some installers use do. If you’re seeing rust trails, someone used the wrong fastener material and the bracket is corroding inside its hole.
- Standing water in the gutter 48 hours after rain. A gutter that holds water becomes a mosquito nursery – something Fort Lauderdale homeowners know better than most. This usually means the original pitch was too shallow, or a splice has created a low point.

AfterReplacement Cost & What’s Included
Here’s the straight answer, because Grant Whitlock has never liked making homeowners call three times to get a number. For a standard single-story Fort Lauderdale home, replacing a 20 to 30-foot faulty run of CertainTeed-compatible 5-inch K-style gutter runs $160 to $420 for the section itself, which includes the gutter, matching hangers, seam sealant, and end caps. Full-home replacement of all gutters and downspouts on a typical 1,800-square-foot ranch runs $1,600 to $2,800. Two-story homes run higher because of the access and the additional safety equipment required.
What drives the range is straightforward: linear footage, whether we’re matching an existing color or installing new runs, the condition of the fascia board behind the gutter, and whether downspouts need to be replaced or only reconnected. We will not give you a low number and then change the invoice once we’re up the ladder. Every replacement starts with a written price before any work starts, and that’s the price you pay. No change orders, no surprise line items.
Every gutter replacement we install in Fort Lauderdale is covered by our 365-Day Done Right Promise: if the work is not right within a year, we make it right. That’s a written guarantee on every job, and it includes a free second visit if the repair fails.
DIY or Call Us?
Gutter replacement is one of the few parts of home exteriors where a careful homeowner can reasonably do the work themselves, and Grant will tell you that straight. If you have a single-story home, a level, a drill, and a helper to hold the section while you set hangers every two feet, you can replace a short run in an afternoon. The materials are inexpensive, and nothing about a 5-inch aluminum gutter is dangerous to handle on a ladder unless you’re working above one story.
Where DIY goes wrong in Fort Lauderdale is the part people never think about: the fascia board behind the gutter. After years of leaks at the seam, the wood is often soft, rotten, or actively coming apart. You’ll set new hangers, they’ll feel solid for six months, and the next tropical storm will pull them clean out. We check the fascia on every gutter job because it’s the difference between a replacement that lasts fifteen years and one that fails in one rainy season. If you’d rather have the whole thing done right and in writing, call (754) 354-1224 and we’ll send someone with a photo ID badge who will walk you through exactly what’s wrong before quoting a price.
FAQs
Expect 15 to 20 years from properly installed .027-gauge aluminum gutters in South Florida, though the sealant at seams typically fails around year 8 to 10. Coastal salt air knocks a few years off that number if you’re east of Federal Highway. If your gutters are older than two decades, replacement is usually more cost-effective than patching piece by piece. Call (754) 354-1224 and we’ll tell you honestly whether your gutters are worth repairing or the whole run should go.
Yes, sometimes. A small seam separation or a single loose hanger can be fixed for under $100 in most cases. But if the gutter is sagging in multiple spots, or the aluminum is cracked at the outlet, replacement of that section is cheaper and more durable than repeated patch work. We’ll give you the written price for both options before you decide.
A single-section replacement on a typical Fort Lauderdale single-story home takes 60 to 90 minutes once we’re on site. A full-home replacement of gutters and downspouts usually takes a full day, and we’ll walk you through timing when we give you the written estimate.
Yes. Our Fort Lauderdale crews carry standard 5-inch and 6-inch aluminum gutter profiles, matching hangers, end caps, seam sealant, and downspout components on every gutter call. For most replacements, we have everything needed on the first visit and finish the job the same day.
