To confirm that your gutters are draining properly, take a quick look after a storm. If water collects in a corner and there is no debris, the gutters are likely to be sloped badly. Call a reliable gutter company to correct this problem right away. Usually, the contractor will use a leveler to realign the gutter section with an incorrect slope.
If folding the hanger (the tool that secures the gutter to the ceiling) isn't enough to set the proper slope, the gutter professional may recommend removing the entire section and hanging it back up. This especially applies to homes with seamless gutters. Installing gutter protectors is an effective way to prevent stagnant water from accumulating in the gutters. If you notice that there is stagnant water in the gutters, especially during spring, it is most likely a bird's nest and you can simply remove it so that the gutters return to work properly.
However, did you know that standing water in your gutters can damage your foundations? Let's take a closer look at how standing water in gutters can affect the foundation of your home. Standing water in a house's gutters can be a sign that the gutters are poorly installed, so when you're looking for new gutters, choose a gutter company that cares about the details and installs them precisely. Your point of view that a gutter doesn't need a “perfect” slope is true, but that's not the same as having a gutter that traps water. If you have signs that water is accumulating around the perimeter of your house, it's a sign that your gutters aren't working and that it's time to build new gutters.
