Checking Your Gutters: A Quick DIY Gutter Inspection

Doing a regular diy gutter inspection is one of those annoying chores that saves you a massive headache—and a lot of money—down the road. It's easy to forget about the metal channels hanging off your roof until you see a literal waterfall pouring over your front door during a thunderstorm. By then, the damage might already be starting. Taking an hour or two on a Saturday to see what's going on up there is the best way to prevent foundation issues, basement flooding, and rotting wood.

Why You Should Care About Your Gutters

Most of us don't spend a lot of time thinking about our gutters. They're just there, catching rain and the occasional stray frisbee. But their job is actually pretty critical. They're designed to channel water away from your home's foundation. When they get clogged or start to pull away from the house, that water goes exactly where you don't want it: straight down into your flower beds, against your siding, and eventually into your crawlspace or basement.

If you let things go too long, you're looking at mold, cracked foundations, and siding that starts to peel and rot. A simple diy gutter inspection twice a year—usually in the spring and fall—keeps you ahead of the game. Plus, it's a lot cheaper to tighten a screw or scoop out some wet leaves than it is to hire a foundation repair crew.

Safety First: Don't Be a Hero

Before you even think about grabbing a ladder, let's talk about safety. Falling off a roof is a quick way to ruin your weekend. If your house is three stories tall or sits on a steep hill, maybe sit this one out and call someone who has the professional gear. But if you've got a standard one- or two-story home and a sturdy ladder, you're probably good to go.

Make sure your ladder is on level ground. If the dirt is soft, use a piece of plywood to create a stable base. It's also a great idea to have a "spotter"—someone to hold the ladder and call for help if you happen to disturb a nest of very angry wasps. Wear some thick work gloves, too. Gutters are full of sharp metal edges, soggy leaves, and the occasional mystery sludge that you definitely don't want to touch with your bare hands.

Start From the Ground

You don't actually have to climb the ladder to start your diy gutter inspection. Walk around the perimeter of your house and just look up. Are there any sections of the gutter that look like they're sagging or pulling away from the roofline? If a gutter is heavy with debris or standing water, it'll start to bow in the middle.

Look at the siding. Do you see any "tiger stripes"? Those are those dark vertical streaks that happen when water overflows the front of the gutter and carries dirt and minerals down the side. Also, check the ground. If you see little trenches in the mulch or washed-out patches of grass directly under the gutters, that's a dead giveaway that water is overtopping the system instead of flowing through it.

Getting Up on the Ladder

Once you've done your lap around the house, it's time to get a bird's eye view. Move your ladder frequently—don't try to lean out to reach that one last spot. That's how accidents happen.

Checking for Debris

The most common issue you'll find is just plain old gunk. Leaves, twigs, pine needles, and those "helicopter" seeds can pack down into a thick mat that works like a dam. Even if the whole gutter isn't full, a single clump of leaves right over the downspout hole will stop the whole system from working.

Looking for "Grit"

While you're up there, look for asphalt granules. These look like heavy black sand. If you see a lot of these in your gutters, it's a sign that your roof shingles are reaching the end of their life. The granules protect the shingles from the sun, and once they start washing away, your roof becomes brittle. It's a good early warning sign that you might need a roofer in a year or two.

Inspecting the Hardware

Gutters are held up by hangers or spikes. Over time, the wood they're nailed into (the fascia board) can get soft or the nails can back out due to the house shifting or the weight of snow. Give the gutters a little shake. They should feel solid. If they wiggle or if you can see a gap between the gutter and the wood, you'll need to tighten the hardware or add some new hidden hangers to pull it back tight.

The Downspout Test

Downspouts are the "exhaust pipes" of your gutter system. If they're clogged, nothing else matters. You can usually tell if a downspout is blocked by tapping on it. If it sounds dull and "full" rather than hollow, you've probably got a clog.

The best way to check this during a diy gutter inspection is to use a garden hose. Stick the hose in the top of the downspout and turn the water on. If it backs up immediately, you've got a blockage. Usually, it's at the elbows (the curved parts). You can often clear these by spraying a high-pressure stream of water up from the bottom or down from the top. If that doesn't work, you might have to take the elbow piece off, which is usually just a couple of small screws.

Finding the Hidden Leaks

Sometimes gutters look fine but still leak. This usually happens at the seams or the end caps. If your gutters are made of sections (rather than "seamless" gutters), they are held together with sealant. That sealant eventually dries out, cracks, and starts to let water through.

During your diy gutter inspection, look for rust spots or white chalky build-up near the seams. That's a sign that water has been sitting there or slowly dripping through. If it's a dry day, you can simulate rain with your hose. Run water into the gutters and watch the underside. If you see drips coming from the joints, you'll want to dry the area thoroughly and apply some fresh gutter sealant. It's a five-minute fix that can prevent a lot of wood rot.

Check the Slope

Water follows gravity. If your gutters are perfectly level, the water will just sit there and become a breeding ground for mosquitoes. Gutters need a slight "pitch" or slope toward the downspouts—usually about a quarter-inch of drop for every ten feet of gutter.

If you see standing water in a gutter that isn't clogged with leaves, the slope is off. This often happens because a hanger has come loose or the house has settled. You can usually fix this by adjusting the hangers to lift or lower certain sections until the water flows toward the exit again.

When to Call in a Professional

A diy gutter inspection is great for routine maintenance, but sometimes you'll find stuff that's a bit over your head. If you see that your fascia boards are completely rotted out, or if your gutters are bent and twisted beyond repair, it might be time to call in the pros. Also, if you're uncomfortable with heights or your roof is particularly steep, there's no shame in paying someone else to do the climbing.

But for the most part, staying on top of this yourself is pretty straightforward. It's all about being observant. If you catch that loose bracket or that small leak in the seam now, you won't be dealing with a flooded basement or a $10,000 repair bill later. Just keep those gutters clear, make sure the water is moving where it's supposed to go, and your house will thank you for it next time the clouds open up.
