Your gutters need attention. The shorter days have told the trees to drop their leaves. Not only that, the rains are about to begin again. Your gutters will be working overtime for the next few months in this area. It is important to keep your gutters clean. This will require cleaning your gutters out several times over the next few months as the different trees around your home drop their leaves at different times.
We all know that the parts that are exposed to the elements (and leaves) are important to keep clean but lets not forget about the underground pipes as well. These pipes are low and out of sight and are easy to forget about. Those underground pipes are probably the most important part of the system as they will collect, concentrate, and (hopefully) remove the concentrated storm water from around your house.
In Marion and the surrounding counties, the underground pipes are usually where things are going wrong and unless inspections or unusually close attention is paid, things can go wrong for months or even years. It really is all about the way we receive rain.
The rains in the Willamette valley, in Salem and surrounding parts of Oregon show up in mid October and things stay moist until the middle of May. We don't necessarily receive a lot of rain, it is just steady and the clouds do not usually part long enough to dry anything out.
A great test for the underground system is to shove a garden hose in it and see where the water comes out. If water bubbles to the surface in the area you are testing or under the home.......you have some work to do.
