Maintaining your Rain Gutters
Always Inspect and clear gutters in both spring and autumn. You also may have to loosen dirt that has blown into the gutters and scrub them with a stiff brush. Flushing gutters with a stream of water from a hose will clear material that has become lodged in the eaves troughs and downspouts.
The slope of gutters may need to be adjusted from time to time to keep water moving toward downspouts. Run water through them, and, if they drain slowly, reposition them so that they slope toward the downspouts at a rate of 1/4 inch for every 10 feet.
Be sure your downspouts expel water well away from your house. If necessary, add downspout extenders to carry the water away (see How to Fix Downspouts That Pool Runoff Water). Also consider concrete or plastic splash blocks, which are slightly sloped and extend away from the house at least 4 feet.
If your climate delivers abundant rainfall, you may want to have your downspouts run into a dry well. The well should be a hole 2 to 4 feet wide and 3 feet deep or a 55-gallon drum, with both ends removed and filled with rocks, that you’ve buried and punctured with holes. Underground drainage pipes should slope to the dry well, which will effectively keep water away from the house’s foundation. Check local building codes before installing.
Also check downspouts for rust, flaking, or peeling paint, plus leaks, and make sure they are affixed tightly against the fascia boards. Check the fascia boards themselves for dry rot or other damage, and, if need be, replace them with lumber treated with wood preservative that is finished to match the other boards.
Below are the simple steps on how you can maintain your gutters.
To clean gutters:
1. Scoop out loose debris. Starting at a drain outlet at the low end of a gutter, use a narrow garden trowel to scoop out loose debris, working away from the drain outlet. It’s usually easiest to do this when the debris is slightly damp and pliable, not soggy or dried and encrusted. To minimize cleanup later, you can scoop the debris into a plastic bucket.
2. Blast out the gutters with a hose. Using an on-off high-pressure nozzle mounted at the end of a water hose, wash out each length of gutter, working toward the drain outlet. This can be a messy job; try to avoid splattering mud all over your house. If necessary, use a stiff scrub brush to remove encrusted dirt.
3. Clear obstructions in drainpipes. If water doesn’t drain freely through the drainpipes, try flushing the debris down them with a hose. If that doesn’t work, use a plumber’s auger (snake) to free and pull out the debris from the bottom or, in some situations, to push it through from the top.
