5 Warning Signs Your Gutters Need Replacing

When was the last time you glanced up at your gutters after a heavy Midwestern downpour? If the answer is “I can’t remember,” we get it—but you could be one storm away from water sneaking behind your siding, eroding your foundation, or staining your brick! Gutters are quiet workhorses until they fail, and failure usually shows up as subtle hints long before you notice a waterfall by the front porch.

In this blog, you’ll learn the five clearest signs you need new gutters, why each one matters to your home’s safety and curb appeal, and what practical steps you can take right now. Stick with us, and you’ll know exactly when “repair” becomes “replace,” saving you time, money, and headaches down the road.

Warning Signs Your Gutters Are Crying Out for Help

Here are the clearest signs you need new gutters—the same red flags many homeowners overlook until water has already caused damage. Use this list to stay ahead of trouble and protect your home before minor issues turn into full-blown repairs:

1) Peeling Paint or Orange Flecks

If you notice paint flaking near the roofline or tiny orange spots on the metal, your gutters are holding moisture instead of moving it away. Those specks are early rust, one of the most significant warning signs for gutter replacement, and once corrosion begins, leaks aren’t far behind.

2) Water Marks Beneath the Troughs

Dark streaks or mildew patches under the gutter run mean water is slipping behind the system instead of inside it. That slow drip can warp fascia boards and damage insulation. Catch it early, and you’ll avoid major repairs later.

3) Sagging or Bowed Runs

Gutters that dip, sag, or pull away from the house can’t drain properly. These low spots collect debris, add weight, and eventually snap brackets. Once the slope is gone, replacement (not repair) is the only reliable fix.

4) Gaps at the Seams or Corners

Visible daylight through a joint tells you the metal has warped or separated. Caulk may work for a bit, but long-term, this is one of the most obvious signs you need new gutters, especially if water is shooting straight onto your landscaping.

5) Overflow During Normal Rain

If water is spilling over the front edge during a basic shower—and the system isn’t clogged—you’re likely dealing with undersized troughs or internal dents restricting flow. Overflow is one of the most overlooked gutter replacement warning signs, and one of the biggest causes of basement leaks in St. Louis homes after every storm.

Why Fixing Gutter Damage Now Saves You More Later

Those small drips, cracks, and sags you spot on your gutters aren’t just cosmetic; they’re early warning signs that water is already starting to work against your home. Overflow washes out soil, leaks rot roof decking, and sagging sections pull away from the fascia, creating expensive repairs down the line. And with repair and material costs on the rise, waiting too long can exacerbate the damage, especially in areas with freeze–thaw cycles and hail, which often leave many homes with damaged gutters, particularly in St. Louis, MO.
