What is not a result of improper gutter drainage?

Improper gutter drainage can lead to a host of issues, including vegetation growth, deck deflection, and fungal growth due to the accumulation of water. In cases where gutters do not function properly, water can overflow or back up, causing water to pool near the foundation or on surfaces where it shouldn't be.

However, "improved water flow" is not a consequence of improper gutter drainage; in fact, it is quite the opposite. When gutters are functioning correctly, they effectively channel water away from the roof and foundation, promoting improved water flow and preventing drainage problems. Thus, the presence of improved water flow actually indicates that the drainage system is working properly. In contrast, when there are issues with gutter drainage, it can lead to stagnant water, which fosters other problems such as fungal growth or unwanted vegetation.
