What is the main concern with vegetation near siding?

The primary concern with vegetation near siding is that it holds moisture. When plants, shrubs, or trees are situated close to building surfaces, they can trap moisture against the siding. This moisture accumulation can lead to significant issues, such as wood rot, mold growth, and even structural damage over time as the siding and underlying materials deteriorate. Adequate clearance between vegetation and siding is crucial for maintaining airflow and allowing surfaces to dry, ultimately preserving the integrity of the home’s exterior.

While other concerns like attracting pests, obstructing views, and causing discoloration are valid considerations, they are not as critical as the moisture issue. Moisture is a fundamental factor that can lead to more serious and costly problems, making it the primary concern when assessing vegetation proximity to siding.
