Rain gutters are much more than a basic water diversion system for your home; they are an essential piece of protection for one of your biggest investments. Unlike commercial buildings, most homes feature pitched rooflines and moderate, though still significant, water runoff that can quickly damage foundations, landscaping, and exterior siding if left unmanaged. A 5-inch K-style aluminum gutter is typically the standard choice for residential properties, offering the ideal balance of affordability, curb appeal, and dependable performance season after season.
