1. Water Spills Over the Edge During Rain
The classic sign. Stand outside during a steady rain and watch: water should flow through the gutter and out the downspouts. If it sheets over the front edge like a waterfall, the gutter is blocked — usually at the downspout outlet or packed solid along the run. This is the sign that means "call this week," because every storm is now dumping water at your foundation.
2. Plants Growing in the Gutter
Yes, really — and it is more common than you think. Decomposed leaves become soil, seeds land in it, and suddenly you have grass, weeds, or even small saplings growing out of your gutter. If your gutters are fertile enough to farm, they are long past due. The roots can also work into seams and make them leak.
3. Gutters Sagging or Pulling Away
Wet debris is heavy — a packed gutter can weigh far more than the hangers were designed for. Sagging between hangers, or a gutter visibly pulling away from the fascia, means the weight has already started winning. Left alone, sections tear loose entirely, usually during the next big storm.
4. Water Stains on Siding
Dark streaks or mildew on the siding directly under the gutters mean water has been overflowing there repeatedly. Besides the cosmetic damage, that overflow has been soaking the fascia board behind the gutter — check for soft or rotted wood.
5. Basement Dampness After Storms
Clogged gutters overflow at the foundation line, and foundation-line water becomes basement water. If the basement gets damp after heavy rain and you have not cleaned the gutters in a while, the roofline is suspect number one. Read our guide on gutters and basement water.
6. Birds, Pests, or Mosquitoes
Standing water in clogged gutters breeds mosquitoes. Packed debris makes a cozy home for birds, and the insects that gather attract more wildlife. If your gutters have become an ecosystem, they need cleaning — and the standing water means the pitch has likely sagged too.
7. You Cannot Remember the Last Cleaning
The most honest sign of all. If you cannot remember when the gutters were last cleaned, it has been too long. Gutters do not send calendar invites; they just quietly fill until something breaks. Put the remembering on us instead — our maintenance plan schedules both annual visits automatically.
What to Do About It
One or two signs: schedule a cleaning soon. Three or more — or any sagging, pulling away, or basement water: call now, because the damage is already in progress. Either way, the visit includes our full inspection, so you will know exactly where things stand.
