In the Pacific Northwest, particularly in areas like Portland, Oregon, where wet weather is a constant, selecting the right composite deck boards is crucial for preventing rot and long term damage. While many composite deck boards perform exceptionally in dry climates, such as California or Arizona, they don’t do well in regions with high moisture content. Let’s explore which types of composite decking materials to avoid and which ones are ideal for these wet conditions.
Composite Deck Boards to Avoid
The primary type of composite decking to avoid in wet climates is wood-based composite decking. These boards consist of a mixture of wood fillers, plastic, and other materials encased in a protective shell. While the outer layer is designed to be weather-resistant, any puncture to this exterior can expose the wood-based core to moisture. Over time, water can seep into the core, causing swelling, rotting, and eventual failure of the board.
Here are a few reasons to steer clear of wood-based composite decking:
- Susceptible to Moisture Damage: The wood fillers in these boards absorb water, which can cause the deck to swell, particularly at the exposed ends.
- Vulnerability to Cracking: If the outer shell is punctured or damaged, the underlying material is left vulnerable, leading to quicker degradation.
- Swelling and Warping: In regions like Portland, where it rains frequently, the exposed ends of these boards can swell, leading to warping and other structural issues over time.
Though they might work well in drier climates, the wet environment of the Pacific Northwest demands something more resilient.
Recommended Decking for Wet Climates
For Portland and other wet regions, we recommend using mineral-based composite decking like Deckorators Voyage. Unlike wood-based composites, these boards contain no organic materials, making them resistant to moisture. Here’s why mineral-based composite decking is a superior choice:
- Water Resistance: These boards are engineered to handle moisture without swelling or rotting. They are even suitable for ground contact and can withstand any amount of water.
- Better Traction: Deckorators Voyage provides 35% more traction than popular brands like Trex, TimberTech, Fiberon, and Armadillo. This increased slip resistance is crucial in a rainy region where decks can become slick, reducing the risk of accidents and liability concerns.
- Comparable Cost: Despite the enhanced durability and performance, mineral-based composites are often priced similarly to other composite decking options, making them a cost-effective choice for long-term use.
Deck Boards from Big Box Stores
Another important consideration when choosing decking material is the quality of the boards sold in big box stores like Home Depot or Lowe’s. While these boards may be more affordable upfront, they are often made with lower-quality materials. Based on insights from manufacturing facility tours, it’s evident that these mass-produced boards are designed for cost savings rather than durability. In a wet climate like Portland’s, opting for higher-quality boards designed for longevity will save you money in the long run by preventing frequent replacements and repairs.
Conclusion
When building a deck in Portland or any other wet area, it’s crucial to avoid wood-based composite deck boards due to their vulnerability to moisture damage. Instead, choose mineral-based composites like Deckorators Voyage, which are designed to withstand moisture, offer better slip resistance, and provide long-term value. Avoid mass-produced decking options from big box stores, as their quality is often compromised to keep costs down. With the right materials, you can build a deck that not only withstands the wet climate but also provides safety and durability for years to come.
