Other gutter protection systems are simply updated versions of unsuccessful designs patented as early as the 1890’s. Simple screens are basically the first gutter protection design. Basic screens are only connected using clips, so they easily blow off in strong winds. They are also damaged easily, collect debris, and require regular maintenance. In gutter systems are basically foam type products laid inside the gutter working as a filter. These systems require regular cleaning to avoid mold buildup and will need to be replaced almost every five years.
