Gutter guard is a kind of protective part of a gutter which can prevent the falling leaves entering into the gutter. Gutter Guard is essential in its goal to provide a maintenance free & self-cleaning gutter protection system.
A gutter guard is any piece that attaches to the gutter and prevents unwanted materials from entering. Usually, those unwanted materials are leaves, branches, and other outdoor debris. By keeping those materials out, gutter guards go a long way in preventing clogs and cracks in your gutters.  A gutter system is not complete without a gutter guard. Gutters are supposed to take water away from the home. If they are clogged, then the water overflows and ends up running down the side of the home and eventually causing foundation problems.
There are three basic types of rain gutter guards namely leaf filters, gutter screens and gutter covers.
The leaf filters can be made either in fine mesh or micro perforated sheet, the gutter screens can be made in various kinds of wire meshes and the gutter covers can be made in perforated sheet.
The gutter guards can be made in plastic and aluminum or other material as requested.
