Gutter guards are a good idea if you live in an area that has a lot of debris (leaves, branches, etc.) that can clog up your gutters. They can help keep your gutters clear and free-flowing, which will help protect your home from water damage. If you're considering getting bigger gutters, make sure to consult with a professional to determine what size and type of gutters would be best for your home. Larger gutters may not be necessary if your home doesn't have a lot of rain or snowfall, and they may end up being more expensive and more difficult to maintain than smaller gutters.
