If home gutter problems occur, consider this statistic: Close to 1,000 gallons of water runs off the roof of a 1,500 square foot home during an inch of rainfall. Defects in the system of gutters and downspouts will become evident as this considerable volume of water stresses all components. Gutter problems that result can cause water leakage inside the home, deteriorate exterior siding, and even potentially damage the foundation of the house. Here's a summary of five common gutter problems:
- Leaky joints. Gutter problems often occur at joints between segments. Standing water trapped inside a clogged gutter is very heavy. This weight gradually pulls gutter segments apart at joints, triggering chronic leakage. To prevent gutter leakage, keep gutters clear of debris that clogs free flow.
- Gutter spillage. A gutter segment may gradually pull away from mounting screws securing it to the house. This will cause spillage down the wall as the detached segment tilts to one side. Check the condition of mounting hardware annually and repair or replace when necessary.
- Frequent clogs. Leaves and twigs may clog the gutter and/or downspout. Trimming back overhanging limbs helps reduce the accumulation of leaves and debris on the roof. Commercially available add-ons such as gutter screens are also available that allow runoff from the roof to enter the gutter while screening out leaves and other debris.
- Inadequate slope. Gutters must be slightly sloped so water flows in the proper direction and volume into the downspout. This prevents gutter problems related to pooling inside gutter segments. For proper free flow of roof runoff, the slope of segments should be slanted 1/4-inch downward per every 10 feet of gutter length.
- Drainage issues. Gutter downspouts should not discharge water on the ground directly below. This may deeply saturate soil adjacent to the house and damage the foundation over an extended time period. The bottom segment of the downspout should ideally extend three feet outward from the house for safe discharge of water. Downspout extensions are commercially available to fit residential downspouts.
