Decks can become unbearably hot during the summer. But with a few strategic design choices and the right materials, you can make your deck comfortable all season long.
At 24×7 Deck Builders, we specialize in creating outdoor spaces that stay cool, so you can enjoy your deck while mitigating the heat on those hot days. Let’s explore how to keep your deck cool in summer using shade, smart material choices, and airflow techniques.
Why Do Deck Surfaces Get Hot?
In Dane County, decks often face prolonged sun exposure, particularly in the afternoon, leading to extreme surface temperatures. Decking can feel 30 to 50 degrees hotter than the surrounding air without shade or ventilation, making it nearly impossible to enjoy.
Dark-colored decking materials and limited airflow beneath the deck exacerbate heat buildup. If your deck faces the sun for much of the day, particularly from the south or west, you might swelter by mid-afternoon, limiting how often you can use the space.
Best Decking Materials to Beat the Heat
When selecting decking materials for your new deck, choosing the right ones can make a huge difference in surface temperatures. Here are some of the best options for hot summer days:
- TimberTech/AZEK: TimberTech’s capped polymer and composite boards are built to resist heat and moisture. The AZEK line of PVC decking stays cooler than traditional composite and is ideal for areas with intense sun exposure.
- Deckorators: Their Mineral-Based Composite (MBC) technology features microscopic air pockets that keep the deck cooler to the touch. It’s a durable material that also expands less in the heat, making it a great choice for long-term comfort.
Does Wood Stay Cooler in the Summer?
Wood is a classic choice, but it can get uncomfortably hot during the summer months.
- Hardwoods (like Ipe and Cumaru) tend to absorb and retain heat, staying warm well into the evening.
- Cedar and Redwood release heat faster, but can still get hot if stained dark.
- Pressure-treated pine can start cooler but darken over time, making it less ideal for managing heat in the long term.
If you choose wood, pair it with shade structures to keep it comfortable.
Deck Shade Strategies That Work in Dane County
Shade is one of the most effective ways to keep your deck cool. Here are several ways to incorporate shade into your deck design:
Permanent Shade Options
- Covered Roof Structures: A solid roof provides full shade and protection from the sun, making your deck usable even during peak heat.
- Pergolas: Pergolas offer partial shade and allow for ventilation. You can add shade fabrics, climbing vines, or louvered panels for extra shade control.
- Louvered Roofs: Adjustable louvered systems offer flexible shade that can be controlled to suit changing sun angles. With this style of pergola, you can better control the amount of shade.
Movable Shade Options
If you prefer flexibility, movable shade structures can be a great option:
- Retractable Awnings: These can be extended or retracted based on the sun’s position, offering adjustable shade when needed.
- Cantilever Umbrellas: These provide shade without obstructing seating areas and can be moved as needed.
- Shade Sails: A great option for customizing shade areas in different parts of your deck, especially for decks with limited overhead space.
Greenery for Natural Cooling
Plants provide natural shade and help cool the air around your deck:
- Tall Planters: Use tall plants like ornamental grasses or shrubs to block the sun where it’s needed most.
- Climbing Vines: Trellises with climbing vines can provide dense shade and add natural beauty to your deck.
- Potted Trees: Trees like serviceberry or birch can offer seasonal shade and can be moved around to follow the sun’s path.
Don’t Forget Airflow
Adding airflow to your deck can help move warm air away, making it feel cooler. Here are a few ways to increase ventilation:
- Ceiling or Wall Fans: Installing fans under a pergola or roof can help circulate air and keep the deck cool.
- Misting Systems: Low-pressure misting systems can reduce the temperature a few degrees, helping you stay comfortable even on the hottest days.
Surface Protection
Even the best materials can get too hot under direct sunlight. One effective way to manage heat is by using UV-resistant outdoor rugs, which reduce heat transfer to your feet and protect the deck surface. These rugs are particularly useful in high-traffic areas, ensuring a more comfortable walking barefoot experience. They also help to prevent excessive thermal buildup, making your deck a cooler place to relax on hot summer days.
