As summer temperatures climb and outdoor living spaces get more use than ever, your clients need deck builds that can take the heat—literally. Whether it’s a lakeside vacation home, a rooftop lounge, or a busy family backyard, durability isn’t just a nice-to-have—it’s the foundation of your reputation as a builder.
That’s where composite decking comes in.
At Evolution Supply, we work closely with leading manufacturers like Trex, TimberTech, and AZEK to provide high-performance composite decking built to withstand extreme weather and heavy foot traffic without compromising on aesthetics. If you’re a contractor, builder, or construction team managing multiple projects this summer, here’s what you need to know about how composite decking holds up when the pressure’s on.
Built for Heat: Composite Decking in High Temperatures
Working in hot, sun-drenched environments? Composite decking performs differently than traditional wood—and that’s a good thing.
Heat Resistance and Color Fade
Today’s top-tier composite products are engineered to resist excessive heat absorption and minimize color fading, even in full sun. While no decking material stays cool under foot on the hottest days, composite boards made with advanced caps and protective layers are designed to reflect more sunlight and retain color stability over time.
Trex Transcend®, TimberTech AZEK®, and AZEK Vintage Collection® all feature high-performance caps that guard against heat-related issues like:
- Board warping or cupping
- Surface discoloration
- Thermal expansion gaps
For rooftops, southern exposures, or wide-open decks with no shade, these capped composite boards are a smart choice to prevent callbacks and keep clients satisfied season after season.
Light Colors Reflect More Heat
Just like roofing materials, lighter deck colors tend to stay cooler than dark tones. TimberTech’s Weathered Teak and Trex’s Island Mist are great examples of options that stay more comfortable underfoot. This is especially helpful for families with kids or pets who are sensitive to hot surfaces during July afternoons.
Standing Up to Moisture: No Warping, No Rotting, No Problem
Moisture is the silent killer of natural wood decks. Rain, humidity, pool water, and ground contact can all cause wood to rot, swell, split, or become slick over time.
Composite decking, on the other hand, is designed to resist water absorption, making it ideal for:
- Lake homes and coastal properties
- Pool decks
- Rain-heavy regions or shaded areas with poor drying
Moisture Resistance in Action
Unlike traditional lumber, composite boards are made from a blend of recycled wood fibers and plastic. Brands like TimberTech PRO® and Trex Select® feature a fully capped surface that repels water, preventing the internal structure from swelling or rotting—even after years of exposure.
Meanwhile, AZEK decking, made from PVC rather than wood composites, is 100% moisture resistant, making it a go-to option for extreme humidity, wet climates, and anywhere mold or mildew could become a concern.
Less Slippery, More Secure
Slippery surfaces are another moisture-related risk, especially around pools or in shaded, damp zones. Many composite brands now offer textured or embossed surfaces that improve traction, even when wet. TimberTech’s Legacy Collection and Trex’s Transcend Lineage are designed with this in mind, providing safer footing without sacrificing design.
Built for Traffic: High-Use Areas Demand High-Performance Decking
Whether it’s foot traffic from entertaining, playtime with kids, or heavy furniture and grills being moved around, decking surfaces take a beating in summer. Composite decking holds up better under frequent use, especially when compared to natural wood that can splinter, crack, or dent.
Scratch and Dent Resistance
Composite decking from premium brands comes with a durable cap layer engineered to resist scratching, denting, and gouging. This matters in high-use areas like:
- Outdoor kitchens
- Entertainment zones
- Commercial patios or rooftop lounges
Trex Transcend® and TimberTech Reserve® are among the toughest when it comes to wear resistance. For heavy furniture, grill stations, or rolling carts, these boards deliver long-term durability without constant maintenance or surface repair.
Color Hold and Stain Resistance
With spills, sunscreen, and outdoor food and drink, summertime can put deck finishes to the test. Composite decking is built with stain-resistant surfaces that clean easily with soap and water—no sanding, sealing, or refinishing required. AZEK’s PVC lines are especially effective for stain-prone areas, making them ideal for busy outdoor kitchens or commercial installations.
Year-Round Low Maintenance = Summer-Ready Decks
One of the biggest advantages composite decking offers is the low maintenance promise. While traditional wood requires seasonal staining, sealing, or even board replacement, composite decking only needs:
- Occasional sweeping
- Basic soap-and-water cleaning
- No sanding or sealing ever
That means your summer projects won’t leave clients with a long to-do list—they can enjoy their space right away and for years to come.
Best Practices for Builders Installing Composite Decking
Composite decking is easier to install than ever, but a few key tips will help you get the best results and avoid problems down the line:
- Mind the spacing: Leave room for expansion and contraction, especially in high-heat zones
- Use compatible fasteners: Hidden fastener systems not only look great but help maintain board stability
- Allow airflow: Proper joist spacing and ventilation underneath prevents heat and moisture buildup
- Follow brand-specific guidelines: Trex, TimberTech, and AZEK each have installation resources—use them
When in doubt, the team at Evolution Supply is here to answer questions and help you select the right system for your job.
