10 Signs You Need New Gutters (Not Just a Repair)

The ten signs

1. Leaks at many seams and corners

Every joint on a sectional system relies on sealant, and sealant does not last forever. One or two leaky joints can be cleaned and resealed. When most joints drip, or a joint you resealed last year is leaking again, the system is wearing out.

2. Sagging along several runs

Sagging means the gutter is pulling away from its fasteners, usually old spikes that have loosened over years of freeze and thaw. A sag holds water, which adds weight and makes the sag worse. A single sagging section can be rehung; sagging across the house points to replacement.

3. Gutters pulling away from the house

Gaps between the gutter and the fascia let water run down behind the gutter. If the cause is rotted fascia along long stretches, the gutters have to come down anyway to fix it.

4. Rust and holes

Galvanized steel gutters rust from the inside where wet debris sits. Small holes can be patched, but rust that shows through in many places means the metal is near the end. Angi notes that steel gutters can rust through within 10 to 15 years without adequate protection (Angi, how to choose gutter gauge).

5. Hail dents and crushed sections

Dents along the gutter lip, crushed outlets and bent runs after a hailstorm affect flow and the fit of guards. Seamless runs are usually replaced by the full run. If several runs are damaged, replacing the system is often cleaner, especially when the roof is being replaced too. See hail-damaged gutters.

6. Overflow even when the gutters are clean

If water sheets over clean gutters in heavy rain, they may be undersized for the roof, pitched incorrectly or short on downspouts. Adding downspouts may fix it; otherwise, replacing with 6-inch gutters and larger downspouts addresses the cause. See why gutters overflow.

7. Standing water that will not drain

A gutter that holds water after rain is clogged, sagging or pitched backward. Repeated standing water rots fascia, rusts steel and breeds mosquitoes.

8. Rotted fascia, stains and peeling paint

Dark stains, peeling paint and soft wood on the fascia or soffit are signs that water has been getting behind the gutters for some time. See fascia and soffit.

9. Water problems at ground level

Erosion lines under the eaves, washed-out mulch, water in window wells, damp basement walls and cracks in flatwork near downspouts can all trace back to gutters that are not carrying water away. Where expansive soils are known to exist, the building code calls for roof drainage to discharge at least 5 feet from foundation walls (ICC, 2018 International Residential Code, Section R801.3 roof drainage).

10. Age

HomeGuide notes that if gutters are over 20 years old or have multiple issues, replacement is often more cost effective than patchwork repairs (HomeGuide, gutter installation cost). Material matters: HomeGuide lists typical lifespans of about 20 to 30 years for aluminum and 10 to 20 years for vinyl, with copper lasting far longer.

When a repair is enough

• One or two leaking joints on an otherwise sound system.
• A single sagging run with solid fascia behind it.
• A crushed downspout or a disconnected elbow.
• One overflowing corner that a splash guard or extra downspout can fix.

HomeGuide lists common repairs such as resealing leaks, adjusting pitch and fixing sags among the most frequent jobs (HomeGuide, gutter repair cost). See gutter repair.

A quick self-check

1. Walk around the house during or right after a heavy rain and note where water drips, overflows or runs behind the gutter.
2. Look along each run from the corner: is it straight, or does it dip between hangers?
3. Check the fascia for stains, peeling paint and soft spots.
4. Look at the ground below each downspout for erosion or pooling.
5. Count how many of the ten signs apply, and to how much of the house.

If several signs apply around most of the house, read gutter replacement and the cost guide.

Timing replacement with other projects

If a new roof, new siding or exterior painting is coming, coordinate the gutters with it. A roof replacement installs new drip edge that the gutters should hang under; a siding job takes downspouts off the walls; painting is easier with gutters down. Replacing gutters alongside those projects avoids paying twice to remove and rehang them.

Photos of problem areas during rain, plus a note of the approximate age of the gutters, make it much easier for anyone estimating the job to tell whether repair or replacement fits your house.

When in doubt, start with a thorough cleaning and a hose test; it often shows exactly which problems are real.
