What wood doesn’t rot in rain?

In regions with rainy weather, the top choices for hardwoods include teak, mahogany, redwood, walnut, and cypress, while cedar stands out as the best option among softwoods. These wood varieties excel in such conditions due to their impressive resistance to moisture. As a result, they maintain their structural integrity and do not succumb to warping or rot, unlike other less resilient woods exposed to similar environments.

Understanding Wood Rot

Wood rot is a natural process where wood fibers break down due to the growth of fungi. Rain and moisture play a vital role in this process, providing the necessary conditions for fungi to thrive. Understanding the impact of rain on wood and the factors contributing to wood rot is essential in choosing the right wood for rainy climates.

The Impact of Rain on Wood

Rainfall can have a profound effect on wood, especially when it penetrates the wood’s surface. The moisture allows fungi to develop and spread, leading to decay. Additionally, repeated wet-dry cycles can cause wood to expand and contract, leading to cracks and weakening the structure.

Factors Contributing to Wood Rot

Several factors contribute to the susceptibility of wood to rot in rainy weather. The wood’s porosity, its natural chemical composition, and the presence of existing decay or damage are critical aspects to consider.
