Deck Waterproofing: Waterproof Deck Membranes By TufDek
Dr. Roof’s professional deck builders install single ply vinyl deck membranes by TufDek™. These systems are fully integrated and can provide thorough waterproofing for a variety of deck designs.
If you’re concerned about whether vinyl deck membranes follow local building codes, we can assure you that our waterproofing method complies with building codes in all of the cities we serve.
Properly sloped waterproof decking prevents pooling water, deck deterioration, and water-collection underneath raised decks and balconies.
How does the waterproof deck installation process work?
Our deck membranes are a vinyl top layer that is adhered to a substrate. In most cases, the substrate is a plywood surface.
Vinyl deck membrane installation involves looking at the slope, type of plywood, structure, and joist spacing of the existing deck before even getting started.
We begin by preparing the surface by fixing any damage, removing hollow spots, ensuring all fasteners are secure, and that all dust and debris are removed.
Testing, sanding, and filling
We then test moisture levels and sand the surface again until it’s smooth and well-prepared for installation. We even remove debris between joints and clean the substrate repeatedly as needed.
Once the surface is clear of debris, we use a TufDek patch compound and ensure all joints are filled in completely.
Directing water runoff
We then use metal flashings coated in PVC to create a drip edge that sits flush with the deck, allowing water to freely run off the deck.
This flashing is held in place by galvanized nails. Galvanized flashing is also installed at deck-to-wall intersects, ensuring no gap is left to collect water runoff. This also helps to support the deck membrane.
Customizing your waterproof deck
Finally, the waterproofing deck membrane is custom cut to fit the deck and rolled out, trimmed, and fit into place before it adheres to the substrate.
The manufacturer-supplied adhesive is then trowelled onto the surface. However, before applying the climate-sensitive adhesive, our deck specialists consider temperature and humidity levels so they can adjust timing and other methods accordingly.
Final touches on your new outdoor space
The membrane is then rolled onto the adhesive and air bubbles are pressed out. Using flat spreaders or heavy rollers to remove the bubbles, we ensure a totally smooth surface.
Dr. Roof considers details such as framing intersects, stairways, steps, door sills, and any other vertical surface where the membrane changes direction and needs to be glued and heat-welded into place.
Overlaps, seams, and areas touching metal flashing are also thermally welded into place to ensure complete waterproofing.
Why is Vinyl Deck Waterproofing Preferred?
Our waterproof decks are stronger under pressure than any other similar product. Our deck waterproofing system is perfect for swimming areas, ramps, balconies, exposed porches, semi-enclosed recreation rooms, and more.
TufDek systems rely on four layers of protective material, including:
- A Bottom Layer of Pure PVC Film
- A Second Layer of Non-Wicking Weft Reinforcement
- A Third Layer of Texture for Aesthetic Appeal
- A Final Layer of UV-Reisistant Polycarbonate

Our process is designed to create a durable, waterproof membrane that still allows flexibility as the wood beneath expands and contracts.
These waterproof coatings are perfect for:
- Boat Decks
- Plywood Decks
- Rooftop Decks
- Swimming Areas
- Hot Tub Areas
- ADA Accessible Routes
