Safety Alert: Trex Decks Pose Risks for Ladder Placement

Composite materials, such as Trex, are a commonly used and viable alternative to wood in decking. Trex is known for its durability, low maintenance, and longevity, which makes it a popular choice among homeowners. However, if your home features a deck made from composite materials, be aware that the planks could present safety hazards when working on the deck with a ladder and even walking across it. If you’re planning to use a ladder to reach a gutter or roof, you should understand the potential risks associated with your Trex deck material.

Even when they’re dry Trex decks are slippery.  When they’re wet, Trex decks can become very slippery. That’s because the composite material used in Trex decking often is mostly plastic and has a low level of friction, which can lead to slips and falls if you’re not careful. Even if your deck has an anti-slip coating, the surface can become hazardous during rain or in humid conditions. In addition, the planks’ smooth surface can make it difficult for shoes to gain traction, increasing the risk of slipping especially when you’re working on the deck.

Unsightly debris and mold can accumulate on Trex decks, making them slicker than wood decks. We recommend regular maintenance to keep the surface clean, since neglecting this can lead to dangers when walking or working on the deck. Over time, leaves, dirt, and other organic material can settle in your deck’s grooves and seams, adding to mold and mildew growth. This “biofilm” can become as slippery as ice and cause sudden falls. Plus, the cleaning process itself can be risky if not done properly by professionals who carefully remove all slippery residues.

The surface texture and material composition of your Trex deck can make it difficult for ladders to grip properly. Composite decking lacks the same roughness and natural grip as wood, which can cause ladder feet to slide, especially if your deck is slightly angled or the ladder isn’t placed perfectly. This slippery condition increases the risk of the ladder slipping out from under you or another person, leading to potential falls and serious injuries. To lessen this risk, you can take extra precautions, like using ladder stabilizers or anti-slip mats, but they don’t always guarantee safety.

While Trex or other composite materials are a great alternative to wood decks, homeowners should be aware of these potential safety hazards.
