Understanding the Challenges of Coastal Climates

Coastal climates present a unique set of environmental challenges that can wreak havoc on traditional siding materials. Before diving into specific siding options, it’s essential to understand these challenges:

High Humidity and Moisture Intrusion

High humidity levels are a constant presence in coastal regions. This moisture can seep into siding materials, leading to rot, mold growth, and structural damage. Materials that readily absorb moisture are particularly vulnerable. The continuous cycle of wetting and drying can also cause expansion and contraction, further weakening the siding over time.

Saltwater Exposure

Saltwater spray and airborne salt particles are ubiquitous in coastal environments. Salt is highly corrosive and can accelerate the degradation of many materials, including metals and certain types of wood. Saltwater can also penetrate the siding’s surface, causing blistering, peeling, and discoloration.
