If you are like most homeowners, you probably use your deck quite a bit during the warmer months. Whether you are hosting a party or simply enjoying a weekend barbecue, your deck is the perfect spot to relax and enjoy the outdoors. But what happens when winter rolls around and all you want to do is curl up inside? If your deck is not properly waterproofed, you could be looking at some expensive repairs! In this comprehensive guide, we will teach you everything you need to know about waterproofing your deck.
How to Waterproof A Deck Over Living Space?
Tip Number 1: Choose The Best Materials
If you’re looking for an attractive, durable, and affordable option for deck waterproofing, a vinyl deck membrane is a great choice. Vinyl membranes are made from polyvinyl chloride (PVC), which is a type of plastic. PVC is strong and flexible, making it ideal for use as a decking material. Vinyl membranes are also resistant to mold and mildew, so they’ll keep your deck looking clean and new for years to come.
Tip Number 2: Install The Membranes Correctly
Installing a vinyl deck membrane is not a DIY project. If you want your deck to last, it’s important to hire a professional contractor who has experience installing these types of materials. The contractor will first clean the surface of your deck to remove any dirt, debris, or oil. Next, they’ll apply a primer to the decking boards. Once the primer is dry, they’ll install the vinyl membrane using special adhesives and fasteners.
Tip Number 3: Use A Drainage System
One of the most important aspects of deck waterproofing is ensuring that water can drain properly from the surface. If water pools on your deck, it can damage the structure and encourage the growth of mold and mildew. To prevent this problem, you should install a drainage system beneath your deck. This will allow water to drain away from the surface, keeping your deck dry and preventing any long-term damage. 
Tip Number 4: Regular Maintenance
Even if you have a waterproof deck, it’s important to perform regular maintenance. This includes sweeping the surface of your deck to remove any dirt or debris. You should also inspect the vinyl membranes for any cracks or damage. If you notice any problems, you should contact a professional contractor to have the issue repaired.
By following these tips, you can keep your deck looking great for years to come. Waterproofing your deck is an important step in protecting your investment and ensuring that your family can enjoy your outdoor space for years to come.
Tip Number 5: Choose The Right Deck Builder
When it comes to choosing a deck builder, you want to make sure that you’re working with a reputable company. There are a few things you can do to research a deck builder before you hire them. First, you can ask for referrals from friends or family members who have had decks built in the past. You can also read online reviews to get an idea of what other customers have thought about the company’s work. Finally, you can contact the Better Business Bureau to see if there are any complaints on file against the company.
Tip Number 6: Discover If Your Decking Material Meets Roofing Standards
One thing you’ll want to keep in mind when waterproofing your deck is that not all roofing standards will be the same as those for decks. For example, most roofing systems require a certain amount of slope in order to work properly. This means that if your deck is too flat, it may not be suitable for a roofing system. You’ll need to consult with a professional to find out if your deck meets the requirements for a particular roofing system.
Why Should You Waterproof Your Deck?
There are a number of reasons why you should waterproof your deck. Waterproofing will:
- Extend the life of your deck by protecting it from the elements;
- Prevent water damage to your home by keeping water from seeping through cracks in the deck and onto your floors or walls;
- Make your deck safer by reducing the risk of slips and falls on wet surfaces;
- Enhance the appearance of your deck by creating a barrier against dirt, grime, and mildew ;
What to Consider When Waterproofing a Deck?
One of the most important things to consider when waterproofing a deck is the type of deck you have. There are three main types of decks: raised, ground-level, and multi-level. Each type of deck has its own set of challenges and considerations when it comes to waterproofing.
1) Raised Decks
A raised deck is any deck that is built on top of an existing structure, such as a house or garage. Raised decks are usually more exposed to the elements than ground-level or multilevel decks, so they require special attention when it comes to waterproofing.
There are two main ways to waterproof a raised deck: from the top down or from the bottom up.
Top-down waterproofing is the most common method of waterproofing a raised deck. It involves applying a waterproof membrane or coating to the top surface of the deck. This can be done by hiring a professional contractor, or by doing it yourself with a do-it-yourself kit.
Bottom-up waterproofing is less common, but it can be more effective in some cases. It involves attaching a waterproof membrane or liner to the bottom of the deck joists before installing the decking boards. This prevents water from ever coming in contact with the decking boards, so there is no chance of rot or mold growth. 
2) Multi-Level Decks
Multi-level decks are any decks that have more than one level. They can be built on top of each other or on different levels of a house or building. Multi-level decks are more exposed to the elements than ground-level decks, so they require special attention when it comes to waterproofing.
There are two main ways to waterproof multi-level decks: from the top down or from the bottom up.
Top-down waterproofing is a popular method of ensuring your deck stays watertight. The process involves applying an epoxy or other type of sealant to the top surface and can either be done by professionals with the equipment you purchase, or it might make sense for homeowners who want complete control over what they do themselves so long as there’s some professional help along the way!
Bottom-up waterproofing is an innovative way to ensure your deck will be free from all sorts of problems. The best part? You can install it before you ever attach any boards, so there are no worries about water coming in contact with them and causing rot or mold growth! 
3) Ground-Level Decks
A ground-level deck is any deck that is built on the ground, without any existing structure to support it. Ground-level decks are the easiest type of deck to waterproof because they don’t require any special attention or equipment.
Waterproofing a ground-level deck can be achieved from the top down or from the bottom up.
Top-down waterproofing is a great way to keep your ground-level deck from sinking and cracking. The top surface of the material needs just about any type of coating, like for example membrane that will stop water absorption by acting as an air barrier plus it won’t let anything seep through into its core which means you’ll never have rot!
Bottom-up waterproofing is an option for those who live in areas that see a lot of rain. It involves installing a membrane or liner on the bottom edge joists before laying boards, which prevents any water from coming into contact with your newly installed decking material and ensures its longevity by preventing rot away at the worst-case scenario. 
No matter what type of deck you have, it’s important to choose the right method of waterproofing to protect your investment.
How Much Does It Cost?
There are several factors that will affect the cost of waterproofing your deck. The size of the deck is the most significant factor. Larger decks will require more material and labor, which will increase the cost. The location of the deck is also a factor. Decks located in areas with extreme weather conditions or those that are exposed to direct sunlight for long periods of time will require more extensive waterproofing and will be more expensive to treat.
The type of waterproofing material you choose will also affect the cost. There are many different types of waterproofing materials on the market, and each has its own advantages and disadvantages. Some types of waterproofing are more durable than others and will last longer, but they may be more expensive upfront.
The best way to get an accurate estimate of the cost to waterproof your deck is to contact a deck waterproofing contractor. They will be able to assess your specific needs and give you a more accurate estimate of the cost.

Waterproof means that a product is impervious to water. That means it won’t let any water in, and no water will be able to penetrate it. Water-resistant, on the other hand, means that a product can resist some amount of water but it’s not going to be completely impenetrable. Water-resistant products will allow some water to seep in, but they’ll be able to withstand a certain amount of moisture or wetness before they start to break down. So when you’re looking for a product to waterproof your deck, you want something that is completely waterproof.
