When it comes to covered gutters, one-piece designs just don’t make sense. Because the top and bottom are made in one piece, if either piece gets damaged, they both have to be replaced. And because the top isn’t removable, it’s very difficult to clean or service the gutter.The newest state-of-the-art integrated gutter systems use a two-piece technology. The top is a separate piece that can be replaced if damaged without replacing the seamless gutter. One type uses a snap-on hood, but snap-on hoods can be easily damaged or blown off in high winds. Gutter Shutter’s two-piece design secures the separate hood to the bracket and trough. The secured hood is very strong, can’t be blown off by the wind and allows easy access if service is ever needed.
