Composite Vs Wood Decking — Which Is Better For A Rainy Climate?

Are you planning to install a deck on your property? Without question, adding a deck can enhance property value and make your outdoor living space more inviting and comfortable. However, when you initially talk to a contractor about choosing the deck flooring materials for the project, you may feel a little apprehensive about making the best decision. Two of the most popular choices are wood and composite decking. 

If you live in an especially rainy climate, you will want decking materials that can stand up to the extra moisture. Take a look at how wood and composite decking stack up when it comes to being resistant to high-moisture climates. 

Durability in Heavy Moisture Climates

Composite decking materials are the better choice when it comes to durability if you live in an area that gets a great deal of rain. Compared to wooden decking materials, composite is far less porous even when unfinished. The particles are both heat-treated and tightly compressed using high pressure, which means moisture particles are less likely to leech into the deck boards and cause deterioration. The exterior surface of composite decking is also more resistant to mold or mildew development and does not need any special treatment to stay resistant to these damaging problems.  

Longevity in Heavy Moisture Climates 

If you are looking for longevity with your new deck, composite is usually the most obvious choice compared to wood. If you live in an area that gets an abundance of rainfall every year, composite is still the better choice. Some of these decking materials actually come with warranties that protect your investment for decades.

Traction in Heavy Moisture Climates 

If your deck will be an area that you use to access the house even when it is rainy, you will definitely want a decking material that gives you traction without getting slippery. In this area, composite decking materials are definitely the better option. The synthetic materials can be finished with a rough or textured surface so it does not get slippery when wet. By contrast, treated lumber does not offer much in the way of traction or texture unless it is painted with a finishing product that contains traction particles. While effective for the purpose, these textured painted surfaces are not all that resilient and have to be reapplied often.
