Deck Materials that are Water-Resistant

When building a new deck, you’ll make a ton of important decisions, perhaps the most important of which will be what material you’ll construct it from. There are many different deck materials you can use, and the benefit is that some of them are inherently water-resistant by nature. Whether it’s that these materials damage extremely slowly in water or they’re not porous, allowing them to form a tight, natural seal, these materials are wildly popular due to their ability to withstand the harshest of Los Angeles weather. Here are some of the most popular water-resistant decking materials and some of the advantages of each of them.


Vinyl has rapidly become a popular decking material for many different applications. For one, its cost is dropping dramatically as manufacturing becomes cheaper and more readily-available. Likewise, more and more options are hitting the market what seems like every single week at this point. While many of these different nylons have different advantages, they all inherently share some of the same properties: they’re cheap, require little maintenance, are lightweight, and easily replaceable. Additionally, the interlocking design these nylon “boards” use to stick together often creates a tight seal, making them virtually completely waterproof without any additional coatings.


Concrete is a popular deck material for commercial installations because of its ready availability, fairly low cost, and extreme durability. Concrete doesn’t crack and splinter in the sun like a wood or some vinyl materials do: it’ll hold its form for decades with few to no issues. In fact, at the most you might see just a few thin cracks develop in areas where the building itself may have shifted or where air bubbles may have formed under the concrete surface. The only real downside to concrete is perhaps the most obvious one: weight. Concrete is extremely heavy, and any deck structure needs to be durable and capable of withstanding the load of thousands of pounds in order to serve its purpose.


Aluminum has many of the same favored properties as concrete, but in a much lighter package. Aluminum is much stronger than concrete for its weight, making it great for rooftop deck installations or other places where a major structure can’t be built. However, it’s one of the most expensive options out there, and that means you’ll be spending a lot more per square foot to install one. While resurfacing with aluminum is also fairly simple, you’ll have to pay particularly close attention to its condition, and you will need to re-seal it periodically to ensure its durability and strength last for as long as possible.

Challenges of a Commercial Rooftop Deck

Rooftop decks have exploded in popularity over the last several years, particularly in urban centers like Los Angeles. When land is at a premium, most property owners don’t have the space to build a deck that’s easily accessible on a lower level, but the roof often sits completely unoccupied. As a result, building owners construct beautiful decks that are not only enjoyable to be on, but provide sweeping views of the area around them.

While these decks might seem like a great idea, there are challenges to building and maintaining these decks that most owners aren’t fully aware of. Here are just a few of those challenges that need to be taken into consideration when maintaining, upgrading, or building a new commercial rooftop deck.

Deck Usage

What do you want to do with your deck? Is it going to serve as a private lounge where you entertain only your highest clientele guests or those of your choosing? Or are you planning on using it as an open-air, elevated nightclub complete with a pool, open-air bar, tables, furniture, and more? If your deck is going to see a lot of use, you’re going to want to build it from more durable, long-lasting materials. This invariably means higher costs and more maintenance, especially if your rooftop deck also has a pool, spa, or other water fixture. Don’t forget, any leaks in your rooftop deck are also leaks into your building, which could do serious damage to the floors below.

Deck Height

How high off the ground is your rooftop? One story? Two stories? Or are you at the top of a sixty-plus story high-rise in the middle of downtown? This is something you need to strongly consider because it’s going to have an impact on what it takes to both construct and maintain your deck. If you’re looking to build a commercial deck on top of a high-rise building, you’ll need to make sure you have room to operate a crane in the vicinity that can lift the materials you need up to the rooftop. Odds are the building elevator isn’t going to have enough space to haul 20-foot joists up several hundred feet, or enough power to support several thousand pounds of concrete. Keep this in mind if you wish to build a new deck or even upgrade an old one to be better suited to commercial purposes.

Deck Drainage

Drainage is an important question if you’re going to be converting a commercial flat roof into useable decks pace. Decks cannot be perfectly flat; they must have at least a little bit of slope to them in order to allow water to reach drains and avoid puddling up in different spots, causing leaks. Not only that, but to even get your building cleared by inspectors, you’ll have to have this slope built in. Keep this in mind: if your roof slope isn’t right at the outset of your deck construction project, it’s going to cost you a considerable amount of extra time and money to ensure the proper slope and drainage is installed.

Deck Weight

If you’re building your deck on your roof, are you positive your roof can handle the extra weight? Concrete is heavy. Water is heavy. Furniture, decorations, glass, and other materials are all heavy. All of this adds up in terms of weight, and puts a lot of strain on your building’s structure. You may be tempted to use a lighter-weight material if structural limits are an issue, but lighter weight materials may not be able to handle the usage loads you’re throwing at them.

Commercial rooftop decks can all benefit from a thorough, regular waterproof service that ensures your deck remains leak-free and durable in all types of weather. Call Capital Deck & Stair Waterproofing today at (310) 912-7737 to request a waterproofing service that’s tailored to your needs!
