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. TufDek™ decking materials come in several different styles and designs that make your deck look aesthetically pleasing while providing quality waterproof decking.

This type of deck membrane is popular for those who have second floor decks with patio space below. The TufDek™ waterproof deck membranes allow the space below the deck to be completely dry, allowing you to enjoy that outdoor patio space even in the rainy and wet conditions of the Pacific Northwest. It also allows you to use the space below for storage space, giving you peace of mind that nothing below the deck will get rained on.

There’s a reason why TufDek™ is the leader in the waterproof deck membrane industry and why Dr. Roof continues to partner with them and recommend them for all of our customers. Creating vinyl decking designs with unique technology is what makes TufDek™ membranes the choice among home owners who take pride in having a good looking, quality deck.

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.

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.

We then use metal flashing 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 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 troweled 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 deck 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

Dr. Roof also offers deck waterproofing with our GacoDeck® acrylic waterproofing kit. This is a water-borne deck system that is applied on top of plywood, stained decks, concrete, fiberglass, and metal decking materials. 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:
