Sagging gutters are much more than just a problem with your house's curb appeal. Anything that interferes with the overall function and flow of your gutter system can result in severe foundation damage, insect infestation, widespread mold growth, and more. Here are a few common causes of gutter sagging and when it's time for a gutter replacement.

Why Your Gutters are Sagging

1. Improper Sizing

Gutter sizes aren't just for creating visual appeal. A house's roof slope will determine the speed at which water runs down into the gutters. A steep roof requires larger gutters to catch the fast-moving surges of water. 

The same is true for all homes in areas where heavy rainfall is very frequent. If your gutters are too small, they'll be overloaded with water and end up sagging. Once this occurs, a gutter replacement with appropriately sized equipment is necessary. 

2. Clogs

It is common for debris, such as fallen leaves, twigs, and dirt, to accumulate in gutters. Since much of this debris is wet, it can be quite heavy, causing the structure to sag. In some cases, it may even separate from the roof. If the clog is caught early, removing it may be enough to resolve the sagging.

3. Unsupported Weight

Modern gutters are supported by hidden hangers. These hangers help support the weight of the gutter and the water it will hold. If the hangers are placed too far apart from one another, sagging will often develop in between. Over time, this sagging will lead to permanent warping of the metal.

4. Warping

The stress caused by sagging can lead to gutters becoming permanently warped or bent. A similar effect can also be caused by the expanding and contracting that occurs during extreme heat and cold. In cold weather, building materials contract and in hot weather they expand.
