Signs You Should Replace Your Gutters

Updated: August 12, 2026Written by: Kenya McCullum

Look out for these nine signs that your home may need gutter repair or replacement.

1. Cracking

A cracked gutter lets water escape and stops your drainage system from working properly. While you can fix a small crack or two, they might point to a bigger issue. If you see several large cracks, it’s time to replace your gutters.

2. Rust

A little rust on your gutters isn’t a big problem and can usually be fixed. But if you notice several rusty spots or large areas affected, it could mean there’s a bigger issue. It’s best to contact a professional soon to see if your gutters need to be replaced.

3. Leaky or Separated Seals

Gutters are weakest where the sections join together. Look closely at these areas for leaks, gaps, or sagging to make sure the seals are still holding up.

A working gutter system directs water to the downspouts. Water shouldn’t spill out of the gutters near your roof.

Check your gutters during a rainstorm to make sure they send water down and away from your home’s foundation. If your gutters leak or clog and you don’t fix it quickly, water can get into your home and cause damage.

4. Paint Damage

Paint bubbles or peeling on your siding likely result from water damage, often caused by a faulty gutter system.

If you see an area with damaged paint, inspect the condition of the nearest gutter and look for any damage. If you’re unsure whether the gutters cause the siding damage, consult a professional for an expert’s opinion.

5. Rotting

Similar to paint damage, water from a broken gutter system can rot siding, window sills, or door frames. Wood siding is especially prone to rotting from damaged gutters. Prevent additional siding replacement projects by proactively repairing your gutter system.

6. Mold or Mildew

Have you seen green or black patches on a house? Damaged gutters might not move water away from your home’s exterior. If you find mold or mildew where it was dry before, bad gutters could be the reason.

7. Roof Separation

Make sure your gutters and roof are attached correctly so they work well. Sometimes, the fasteners can get loose or break and just need to be replaced. If this keeps happening, check the fascia boards for rot. If you find rot, you’ll probably need to replace your gutters.

8. Sagging

If parts of your gutters sag, water can pool there. This can cause water to spill over and may lead to cracks or gaps. You might also see damage to your landscaping after rain or notice flooding, which could mean your gutters are sagging.

9. Flooded Basements

If water builds up where it shouldn’t, it can seriously damage your basement or foundation if left alone. Fix this problem as soon as you find it.

How to Avoid Gutter Damage

It is worth noting that gutter replacement projects are typically much more affordable compared to fixing the damage that occurs when they are neglected. However, all of this can be avoided by being proactive and caring for your gutters routinely.

Cleaning gutters isn’t the most fun job, but it helps prevent future problems. Cleaning and checking your gutters about twice a year keeps them working well and helps you spot any issues that might need repair or replacement.
