Local Context
Water-damaged boxes in a garage can result from various structural weaknesses and environmental conditions. One common cause is water infiltration through the roof or walls. Over time, broken or damaged roofing materials, missing seals, or improperly installed flashing can allow rainwater to seep into the structure. Moisture may then travel along surfaces and settle into boxes that are stored near the edges of the building.
Garages often experience temperature fluctuations that lead to condensation. When warm, humid air interacts with cold surfaces, moisture forms. This can dampen nearby items, including storage boxes, even without any direct exposure to rain. Poor ventilation exacerbates the issue, allowing moisture to accumulate over time.
In some cases, the source of moisture is not the rain at all but rather leaks from plumbing or even rising groundwater. If the garage is attached to a home or close to underground water lines, slow leaks can gradually saturate stored boxes. Additionally, water can seep upward from the foundation if moisture is pooling around the base of the structure.
Severe weather and external environmental factors also play a significant role in causing water damage. Heavy downpours, flash floods, and even wind-driven rain can force water into areas that would normally remain dry. In regions such as St. Louis and Nashville, these conditions are not unusual, and improper protection or maintenance may leave storage areas vulnerable to unexpected moisture.
