Walkable Roofing, Rooftop Decks and Outdoor Living Spaces

Duradek introduced its vinyl decking material over 40 years ago. They developed it as a waterproofing solution for decks that previously didn’t exist. Since then, Duradek vinyl decking has become the perfect solution for residential and light commercial outdoor living spaces.

These vinyl decking materials and roof deck membranes are inviting, long-lasting and low-maintenance. In addition to its strength slip resistance durability, Duradek completely seals any deck substructure making sure water never reaches the structure below.


If you’re building or renovating a rooftop deck, be sure to top it off with roofing that’s both waterproof and walkable. Duradek is a 100% waterproof PVC roof decking system made from a highly durable material, professionally installed with heat-welded seams to create a watertight seal so you can enjoy your deck worry-free.

It’s also available in several designer colours and doubles as a high-performing roof to protect your living space. In addition, it’s a comfortable, slip-resistant walking surface for your outdoor living activities above.

An adequately prepared subsurface is one of the most important considerations when preparing for your Duradek installation. The better the subsurface, the better the result. To achieve this, our authorized installers use the recommended 5/8″ T&G untreated plywood to create the flattest subsurface possible. In addition, to avoid pooling or ponding, which can lead to premature discolouration or deterioration of your vinyl decking, a 2% slope of the subsurface is ideal.

It’s essential to seal any posts or pillars penetrating the vinyl to prevent water from getting under the vinyl and into the subsurface. We strongly recommend regular caulking and inspections of your deck to ensure the integrity of your Duradek installation. If possible, you should permanently fasten posts to the fascia. Any surface-mounted bases must be covered entirely with a waterproof membrane and clad. If you’re attaching metal rails or posts to the vinyl decking surface, you should fill the pilot holes with a sealant before inserting screws.
