Your home's gutters are very important for the overall maintenance of the structure itself; those gutters are meant to direct rainwater away from the home's exterior walls and foundation so that these materials don't suffer water damage and resultant cracks. The downspouts also allow water to flow away from the property's soil so that you don't have small floods in the yard, and so that the soil doesn't become overly moist and soft. Because gutters and all connected pieces are so important to your home and property, you want to ensure they are all installed properly; note a few reasons why homeowners should avoid doing this installation work on their own.
Don't assume that larger gutters are always the best for your home. Oversized gutters may allow in more leaves, twigs, rocks, and other such debris, which may just sit in the gutters and allow them to clog. This added weight can also cause the gutters to pull away from the home's roof. If your home's gutters are constantly overflowing, you might need to upgrade to a larger size, but it might be recommended that you add screens to the gutters so that you keep out all that debris that often causes them to overflow.
Gutters aren't just attached evenly to the side of the roof, but they need to be angled toward the downspouts so that water flows in that direction and doesn't just pool inside the gutters. However, you also don't want to angle the gutters too sharply, as then water might flow too quickly, causing overflow where the downspouts are connected. A professional will ensure that they're angled properly according to the length of the gutters and their overall capacity.
Many gutters today are seamless, meaning that they're made of one long piece of vinyl or another material, and then a factory will cut them to size. This reduces the risk of leaks from the gutters, as those seams between guttering pieces can start to loosen and allow water to drip through.
However, even seamless gutters still need to be connected properly to downspouts and the roof itself, and if you don't choose seamless gutters, you'll need to ensure guttering pieces are also properly connected to each other. Using the wrong connectors or not connecting all pieces of the gutters properly can lead to sagging gutters, gutters that pull away from the roof, and potential water leaks.
