It’s no secret that outdoor spaces are cherished in our harsh Canadian climate. By the time spring arrives, most are eager to set up their outdoor abodes. For the majority of homeowners, deck maintenance might not be top of mind when it comes to easing back into the summer season. And while decks aren’t as fun as flashy throw pillows and new barbeques, they are an important component of many outdoor spaces.

And with the cost of deck replacement reaching well into the thousands – it’s important to protect your investment. Moisture, in particular, has a sneaky way of wearing down your deck more quickly than you might imagine. That’s why deck waterproofing is such an important part of any long-term maintenance program.

What is Deck Waterproofing?

Deck waterproofing can be done using a variety of materials. However, two of the most popular applications are vinyl and polyurethane. However, Newport Dry Decks does not use vinyl materials because they are inferior to polyurethane and the end result is far lower in quality. We value quality over quantity and only use the best materials for your deck.


Vinyl deck waterproofing is completed using a material that comes in pre-measured rolls. The material is rolled out over the deck surface and secured using an adhesive. Because the material comes pre-measured, there will be seams – these are also sealed using an adhesive. Because the new vinyl membrane needs to be glued 8” up the exterior wall of most homes, siding and sliding doors often need to be removed and re-installed as part of the process.polyurethane deck waterproofing


Polyurethane deck waterproofing is completed using a liquid roofing material that can be molded around existing obstacles. This means that siding and sliding doors typically do not need to be removed. When the material dries, it forms a completely waterproof finish wherever it has been applied.

Which Deck Waterproofing Should You Choose?

While vinyl deck waterproofing can be installed quickly, it has significant downsides. As mentioned, new installation and eventual replacement can require additional work when siding and doors need to be removed and reinstalled. In addition, the seams can take away from the overall deck aesthetic while presenting a point of entry for moisture.

Although polyurethane deck waterproofing requires additional steps and intervals of drying time, it does not require the removal and reinstallation of siding and doors. The material can be applied using a trowel, creating a waterproof surface without all the hassle. Polyurethane also creates a completely seamless finish, which many will find visually appealing. This traditional roofing material is nearly indestructible, can be cleaned with almost anything, and lasts a lifetime.

Which Deck Waterproofing Costs More?

Here’s the good news – both methods cost nearly the same! While the time and material costs of polyurethane may be higher, its easier installation equates to savings over new vinyl deck waterproofing. Whichever method you choose, make sure you don’t look past the importance of proper deck maintenance. Now get out there, start up the barbeque, and soak up the sun!
