How Gutters Protect Your Foundation
A roof is a big funnel. Every square foot of it catches rain, and all of that water has to go somewhere. Without gutters, it runs straight off the edge and lands in a narrow strip right next to your house.
A single hard rain can dump hundreds of gallons off an average roof — all of it soaking into the soil against your foundation if it is not caught and carried away.
What happens when water sits by the foundation
Oklahoma soil is the other half of the problem. Much of it is clay, and clay swells when it gets wet and shrinks when it dries out. That swelling and shrinking pushes and pulls on a foundation, season after season. Over time, it can open cracks, shift walls out of square, and let water into a basement or crawl space.
Even without clay, standing water washes soil away from under slabs and walkways, leaving them to sink and crack, and pooled water will eventually find any small crack or joint in the wall. This damage is slow and quiet — you may only notice it when a door starts sticking or a crack shows up in a wall.
How a working gutter system moves water away
A gutter system's job is simple: catch the water coming off the roof, carry it along the edge of the house, and drop it through downspouts where it can be sent away from the foundation. Elbows at the bottom of the downspout turn the water outward, and extensions carry it farther still, so it soaks into the yard instead of the soil against the wall.
That only works if the whole chain is intact. Gutters must stay hung securely and sloped toward the downspouts, joints and end caps must stay sealed, and downspouts must stay clear so a heavy rain can get through instead of backing up and spilling over the top. Gutter guard and screens help by keeping leaves and debris out, so water keeps flowing instead of damming up behind a clog.
Signs your gutters are not doing the job
Walk around your house after a good rain and look for these warning signs:
- Water pouring over the edge of the gutter instead of running to a downspout
- Mud splashed on the siding, or a washed-out trench below the eaves
- Downspouts that end right at the foundation with no elbow or extension
- Gutters pulling away from the house, sagging, or holding standing water
- Damp spots, staining, or white, chalky residue on the foundation wall
- Doors or windows that have started sticking, or new cracks in interior walls
Any one of these is worth fixing before the next storm season, because the next hard rain will make it a little worse.
Keeping the system working
Twice a year is a good rhythm for most Oklahoma homes: once after the leaves fall, and once in the spring before storm season. Clear out debris, flush the downspouts, check that hangers are tight, and reseal any joint that is dripping. Make sure downspout extensions are still in place — they are the first thing to get knocked aside by mowing, and a downspout without one just pours water back against the house.
If a section is rusted through or split, replacing it beats patching it again every year. Gutter coil, downspouts, elbows, hangers, and sealant that fit together make a system that holds up, and they are available in 7 colors to match the house.
A small system doing a big job
Foundations are expensive to repair. Gutters are the opposite: a simple system that quietly keeps thousands of gallons of water a year from reaching the one part of your house you least want it to touch. Keep them clear, keep them sloped, and keep the downspouts pointed away from the house.
