The most common types of gutter failures are: Clogs; Leaks; Misalignment; and Faulty Design.
The most common type of gutter failure is a clog. Leaves, dirt, shingle grit, and other debris flow into your gutters but not out. Over time, more debris creates weak water flow and leads to overflow.
Any standing water in your gutters will increase the likelihood of leaks and cracks; particularly in winter seasons when standing water can freeze and cause ice damming.
Often a secondary effect of clogged gutters, misaligned gutters occurs when gutters sag, bow, or break away from the roof’s edge.
Roofs with peaks and valleys may experience intense water flow towards sections of gutters. If the gutter system is not properly installed, the result could be an overflow from the system’s inability to divert the water.
