7 Signs Your Gutters Need Cleaning Right Now
February 10, 2025 · 4 min read
San Diego may only get around 11 inches of rain per year — but when it does rain here, it often comes in heavy bursts. Clogged gutters that can't handle that sudden flow cause the kind of water damage that runs into the tens of thousands. Here are the seven signs you need to act now.
Plants growing from gutters
If you can see grass, weeds, or even small plants sprouting from your gutters, you have a serious blockage. Organic debris has accumulated deeply enough to support plant life — and roots can crack gutter joints and pull sections away from the fascia.
Water spilling over the sides during rain
This is the most obvious sign. If water pours over the edges of your gutters during rain rather than flowing through downspouts, they're completely blocked. Every overflow event soaks your fascia boards, soffits, and foundation.
Staining or mildew on exterior walls
Dark streaks running down your siding below the gutters, or mildew patches near your roofline, mean water has been overflowing and wicking into your walls for some time. The longer it goes, the more expensive the repair.
Sagging gutter sections
Gutters should be straight and slightly angled toward downspouts. If sections are visibly drooping or pulling away from the house, the weight of waterlogged debris is warping them. Left too long, sagging gutters need full replacement.
No water from downspouts during rain
Step outside during the next rain and watch your downspouts. If no water comes out while rain is hitting your roof, the downspouts are completely blocked — which means every drop is backing up and overflowing somewhere.
Pests or bird activity near gutters
Stagnant water and decomposing debris in gutters attract mosquitoes, roof rats, and nesting birds. If you've noticed unusual pest activity near your roofline, check the gutters — they may have become an unintended habitat.
It's been more than 12 months
Even if you can't see any of the above, gutters accumulate fine debris, dust, and sediment that restricts flow without being obvious. San Diego's eucalyptus, palm, and pine trees shed constantly. Clean gutters every 6–12 months regardless of visible symptoms.
💧 The Real Cost of Waiting
Professional gutter cleaning is one of the most affordable ways to protect your home. Water damage to fascia, soffits, foundations, or interior walls caused by overflowing gutters typically costs $2,000–$15,000+ to repair. The math is obvious.
