One of the most important aspects of home maintenance is the upkeep of your rain gutters. In order to make sure your gutters are working properly, you must know how to adjust them in case they fall out of place or become corroded. Overflowing gutters can also be a result of an inadequate slope. You should always be aware of the condition of your rain gutters.
Clean out the gutter using your rake. If you don't clean out the debris from your gutter before starting this project it will fall when you try to readjust it.
Put on your gardening gloves before beginning. In order to adjust the slope of your gutter, you must first pop the pegs out that hold the gutter up around the corners and side. Make sure that you attempt this only a few brackets at once. Using a screwdriver, carefully work the drip edge until it is loose. You can then loosen the rest of the gutter using a crowbar or a hammer. Drop the rain gutter to the proper angle, making sure that it slopes downward toward the downspout. Your gutter will drop about one-quarter of an inch for every four feet of length. The best way to ensure this is to hammer a nail into the wood about an inch below each end of the gutter, then tie a string between the two. Underneath, tie another string along the gutter, but make sure this one is level. Using a professional leveler for this is best. Measure the distance between the lines at every four feet. The distance between the two lines should increase about one quarter of an inch for every four feet of gutter. If this does not occur, then you must realign your gutter again.
Replace the pegs that hold up the gutter. Make sure you use a block of wood to hammer these back in place, so as to not damage the soft metal of the gutter. After you have the gutter pegs popped back in, you can use silicone caulk to reseal the gaps that have appeared as a result of realigning your gutter. Simply apply the caulk directly to the gap, making sure it covers the entire gap. Now wait for it to dry.
Test the new slope of your gutter by using a garden hose to run water down it. The gutter's slope should cause the water to flow downward toward the downspout. Another good way to test if your gutter is properly aligned is to place a marble in it and see if it rolls down to the downspout.
Readjust your gutters accordingly if the test fails.
