Clogged gutters can cause water leakage into the house as the water backs up. Clogged gutters can also lead to stagnant water build up which allows mosquitoes to breed and also allows grasses and weeds to grow in the gutter.
Gutters must be maintained regularly to remove leaves and other debris to keep them from clogging. Gutters that are filled with debris can overflow and soak the foundation, damage the roof structure, and exacerbate ice dams in cold climates.
Effective gutter guards that keep debris out but allow water to enter are a good alternative to regular cleaning.
Gutter protection devices include:
Snap-in metal and plastic gutter guards
Filtered gutter guards
Stainless steel gutter guards
Hinged gutter guards<br>
Plastic and metal total gutter covers
Gutter brushes
Regardless of the gutter guard protection used, all gutter systems should be examined for cleaning and repair twice every year.

Another option is to use a closed gutter to ensure that debris and leaves do not enter the gutter. The continuous hanger is a way to protect gutters from clogging and damage while reducing required cleaning to a minimum
