Why Do I Need A Waterproof Membrane for Decks?
One aspect that would-be deck builders should take seriously is waterproofing, particularly when constructing a roof garden. Failure to waterproof your roof deck can lead to extremely costly repairs to habitable areas below due to leaks. There is the cost of repairing the leak in the roof and then drying out the room below and redecoration. It doesn’t bear thinking about, does it?
A Waterproof membrane for decks is one way you can ensure your roof garden is watertight. When choosing a deck frame membrane, it’s important to select the right materials. Not all membranes are held to the highest standards and putting down a membrane is a job that you don’t want to be repeating for a number of reasons. Firstly, it can involve taking up all the decking boards if you have selected a fabric type membrane, and secondly, if you need to replace the membrane, it’s because you have a leak.
What To Consider When Choosing A Waterproof Membrane For Outdoor Decks
It’s a false economy to go for the cheapest product on offer. When you choose a waterproof roof deck system, you should consider whether it’s flame and UV resistant, whether it’s suitable for high volumes of traffic, and the expected durability of the product. Whether you choose a fabric type membrane or a vinyl covering, there should be a minimum level of thickness to ensure that your deck will remain watertight for years to come.

Vinyl Or Membrane Exterior Deck Waterproofing Systems?
Some people like to choose a vinyl covering that covers the whole deck. The advantages of this rooftop decking material are that it can be less slippery than wood or composite surfaces. It also can be far easier to clean as it’s one smooth surface rather than decking boards which may have ridges and gaps. Many vinyls are stain-resistant, meaning if you do happen to spill something like oil on them, they can be cleaned easily without leaving an unsightly mark.
A waterproof membrane for outdoor decks can also come in roll form like a fabric. A layer of this membrane is laid down under the deck, providing a waterproof layer. This is similar to lining a roof to keep the elements out. A fabric type membrane can be a cheaper option than using a vinyl membrane, but there are reasons why most professional venues choose vinyl. In short, it’s more durable and there is far less chance of leakage down the line.
