What are gutters primarily used for?

Gutters are primarily designed to divert water runoff from the roof away from the foundation of a building. This function is crucial in preventing water damage to the structure, which can occur when rainwater overflows or accumulates around the foundation. By directing this water to appropriate drainage areas, gutters help to mitigate issues such as erosion, mold growth, and damage to landscaping.

While snow collection and enhancing aesthetic appeal are functions that may be associated with gutters, they are secondary to the primary purpose of water diversion. Supporting the structure is not a function of gutters; rather, they are components of a roofing system that work to manage water flow efficiently.
