The stars are shining, the evening breeze is blowing, and you’re sitting back on the deck with something cool in your hand. Oh, and you also happen to be on the roof of your building!
A rooftop deck is an experience like no other, allowing you to relax from a unique, elevated perspective. Whether yours includes a pool, outdoor kitchen, or simply a sweet patio set, you’re sure to get lots of enjoyment from it as the years go by.
If you want to build or replace one, it’s important to know the right rooftop deck materials to buy. Today, we’re sharing some of the most common options to help you make a more informed buying decision.
Key Considerations to Remember When Building a Rooftop Deck
Though it might look the same once you’re up there, a rooftop deck is significantly different from a ground-level one. Not only should your materials be sturdy and durable enough to support all the weight they’ll hold, but they must also be able to maintain their color and finish amid extreme weather exposure.
These structures receive more direct sunlight than lower alternatives, and the same applies to forceful winds, fast-moving hail, and torrential downpours. While you obviously want a decking material that will look great, you’ll also need to make sure it offers the longevity you need at a price point you can afford.
With that in mind, let’s take a look at a few of the choices you can consider.
1. Pressure-Treated Wood
Put simply, raw wood isn’t capable of withstanding the adverse weather that a roof deck will encounter. If you’re sold on the look of wood and want to keep the aesthetics authentic, then we suggest investing in pressure-treated wood instead.
Most outdoor decks in the U.S. use chemically-treated, weather-resistant planks of Southern yellow pine. When your deck is first installed, the planks might look light green in color, but this will fade to a softer, yellower tone after about six months. Eventually, after years of exposure to the elements, pressure-treated wood starts to look light gray or silver.
While it might be sturdy, you’ll still need to take great care of your wooden deck. In addition to cleaning it thoroughly once a year, it’s also smart to give it regular once-overs to remove any debris, scrub away mildew, and keep it looking its best.
Apply a sealer to your wood once a year to help it withstand solar damage, as well as water damage. While they might be less vulnerable to pest infestations and rot, pressure-treated varieties can still warp if they get too hot or too wet. Before you seal it, apply an exfoliating deck-cleaning solution to prep the surface and allow the sealer to seep in as deeply as possible.
2. Hardwood
Real hardwood decking will cost more money than pressure-treated wooden decking. Yet, this is a case of getting what you pay for. This type of deck will be even more resistant to wear and tear, and can also stand up against extreme temperature fluctuations.
Plus, it’s aesthetically beautiful. Hardwoods are distinguished by their natural characteristics and unique textures, which can be difficult to replicate in a factory. To help them maintain their sheen, you may need to apply regular coats of stain.
Keep in mind that it’s important to take great care of your hardwood decking. Imagine what would happen if you left a piece of heirloom furniture out in the rain or snow! While it can last for years under the right conditions, many homeowners are surprised at how much time and energy goes into helping them look their best.
Untreated hardwoods will turn lighter over time, which may not be a major concern to you. However, regular upkeep is necessary to keep them in sturdy, safe condition. It will also help curb any painful splinters that may result from walking barefoot across the surface!
3. Cedar
Cedar is not considered a type of hardwood, but it can be a great choice for your rooftop deck. However, it’s best to use it only on decks that aren’t used too frequently, as it doesn’t hold up as well against regular foot traffic as some others.
Cedar is long-lasting and is naturally resistant to rotting, moisture, and insect attacks. It also isn’t as likely to split or crack as pressure-created wood and is easier to maintain on an annual basis. When you first install a cedar deck, you’ll be impressed by the rich, red tone of the wood.
Though it will fade to a silver/gray if you don’t keep it cleaned and sealed, even rustic cedar can look beautiful. Most standard options will highlight the cedar’s natural knots and imperfections, but if you prefer a smooth and uniform finish you can always sand, seal and treat the wood with the finish you choose.
4. Composite Decking
Love the look of a wooden deck, but don’t want to worry about the upkeep? You can save time and money in the long run by investing in a composite deck instead. Designed to look very close to real wood, it’s much easier to maintain than the real thing.
Even after years of being exposed to severe weather, composite decks will still look similar to how they did when you first installed them. You don’t have to worry about them fading or changing color in the sun, and mildew will only grow if you allow water to accumulate in damp, shady spots.
The best part? You never have to worry about sealing or staining a composite deck. You can also ditch the stains, finishes, and paints. These boards are ready to use, right out of the box.
While you might spend a little more upfront to procure a new composite deck, you’ll easily recoup that money over the years without the need to invest any more in additional upkeep. Browse the different grain options and choose one that you love. You can even find options made from recycled plastic items and wood fibers, which makes your home greener and more environmentally friendly.
5. Steel
When you want to make sure your roof decking is secure, few options surpass the durability of steel. In fact, we recommend using steel for both your deck frame and your flooring surface. Otherwise, you could wind up replacing your frame before your boards give out, which can create a logistical nightmare.
You can find steel decking in a variety of different finishing options. For a more rustic look, consider galvanized finishing, which allows the metal to shine in all its original glory. For a more refined look, check into a prime-painted finish in a neutral color that complements your exterior.
6. Synthetic Grass
Did you decide to build a rooftop deck because your outdoor space is at a premium? If you envision escaping to yours as a retreat from the busyness of city life, then you may want to look into synthetic turf or synthetic grass.
Meant to replicate the real deal, this decking material usually goes on top of a standard substrate decking base. You can choose to install full areas of just green space, or have a little fun with the pattern and design of your turf! Why not transform your deck into a plein-air putting green?
Most synthetic turf is sold in large rolls, made out of a polyethylene plastic material. Designed to replicate the look and feel of individual grass blades, it looks authentic but you’ll never have to mow it! For best results, look for one that includes a pre-applied UV treatment to prevent the turf from fading or becoming discolored in the sun.
7. Porcelain
You may think of porcelain as a material that’s best reserved for your bathroom shower or kitchen backsplash. However, did you know that it’s also durable enough to support a rooftop deck?
Not only is it rugged and strong, but it’s also lightweight. This makes it an ideal option for such a tall surface, as it won’t place a ton of extra strain on your structure.
Plus, porcelain decking is refreshingly low-maintenance. As long as you wipe the boards down every so often with water and a mild detergent, you can keep the deck free of dirt, grime, and mildew.
Most manufacturers will create porcelain pavers, designed to be installed side-by-side to create a smooth decking surface. This gives the floor a smooth, seamless look that serves as the perfect backdrop for your patio landscaping. You can find these pavers in a variety of different colors, patterns, and finishes so take your time and choose ones that appeal to you.
For an even more luxurious rooftop experience, look for porcelain deck products that integrate with radiant heat systems. Can you imagine walking upstairs and into the night, with a warm floor at your feet?
8. Rubber Tiles
Does the idea of walking on a rubber deck on a bright, sunny day make you raise your eyebrows? If so, take heart. These tiles are surprisingly comfortable and don’t retain heat as you’d expect.
Instead, you’ll discover that they’re heavy-duty, reliable, and versatile. For this reason, many commercial property owners turn to rubber tiles when installing outdoor recreation courts and gym facilities. Yet, they’re equally beneficial in residential installations.
A standout benefit of rubber decking is that it’s water-resistant. If you live in a climate that sees a significant amount of rainfall each year, this is an important consideration to keep in mind. You can rest assured that you’ll maintain your footing and keep your traction, even in the slippiest conditions.
Rubber tiles also tend to be more cost-effective than other varieties on this list, and you can use them to cover a large number of square feet with ease. Most tiles feature interlocking edges that join to one another seamlessly.
9. Plastic Perforated Tiles
Plastic perforated tiles also work well on rooftop decks. These tiles are excellent at draining off water, which will help your surface last longer and resist premature rotting. Though they can be polarizing, plastic decks are worth a second look, even if you’re concerned that the surface will appear too unnatural.
Most of the time, these tiles are made from a sturdy PVC material that helps prevent fatigue and delivers excellent traction. The tiles connect together via a loop-and-tab system that will stay securely in place. You can also find plastic decking planks if you don’t prefer the look of a puzzle-piece design.
If you just need to repair an existing rooftop deck that needs some TLC, it’s worth looking into plastic perforated tiles. As long as the deck is structurally sound and safe, these tiles can help freshen its look and restore its luster. You can install them directly on top of an existing wooden or concrete deck, without the extra costs associated with sanding, staining, or restoring the surface.
One caveat to keep in mind? The PVC material can expand and contrast with major temperature fluctuations. If you live in an area that’s prone to these surges throughout the year, then it’s best to look at a different option.
