While having a roof deck is a great way to increase living/entertaining space, one of the biggest issues that many homeowners experience is frequent leaks.

Properly waterproofing a roof deck is often a challenge, because the materials used most frequently, either EPDM rubber, or a Tar/built-up material, do not offer solid protection against leaks.

However, there is a much better, longer lasting alternative: a TPO roofing membrane. Its designed with hot air-welded seams, which makes it impervious to water infiltration.

While a TPO membrane costs more than rubber, you get the benefit of enjoying a leak-free roof deck for years to come. Also, since roof decks are typically small the real difference in price is miniscule and can be as little as $200-400. Therefore it is always preferable to use TPO membrane instead of rubber.

Learn more about TPO membrane costs, as well as pros and costs of installing it on your deck.

Water Proof A Concrete Slab Roof Which Serves As A Roof

I am looking for a solution that would add minimum thickness to the slab. The deck is surrounded by a railing which would have to be replaced to meet code if the deck surface is raised too much. Two inches would be OK. The initial thought is a membrane but I would like to have a ceramic or manufactured stone tile surface. Is there a membrane material robust enough to accept these materials applied directly on the membrane? Any suggestions for another finished surface?

The Aquron Waterproofing System

The holistic Markham approach to waterproofing can completely remove the need for waterproofing membranes in many structures.

  • Intelligent slab pour and expansion joint design, to avoid movement cracking.
  • Aquron hydrogel treatment as an admixture and spray-applied to the exposed face.
  • Superswell waterstops, and strip drains if required, for water control at the joints and penetrations.

Its crucial that this approach is implemented from early design stages.

Libbie, a handy woman hailing from Port Alberni, British Columbia, Canada – our northern ally – emailed me with a great message. Read it for yourself:


Love your videos: I am a pensioner with limited physical ability ~ BUT ~ consider myself able to do a lot of handy work, the house has a concrete deck on the second floor and I have water ingress issues into the garage area below via one minor crack on the surface and crumbling flashing at the edge of the deck. This seems to occur when the snow melts on the deck

I need to know if I have to inject silicone into the cracks and then use a hydrolic cement patch product. I do not have the $ to remove the cement and replace with a wooden deck: I live in a rainforest area. Help me OBeWan! I LOVE your website and concise way of teaching. Thank you so much.”

Libbe, the LAST thing I would inject in that crack is silicone.

I’ve written extensively in the past about EPOXY injection materials for concrete cracks.

To get these magic products to work, you need to make sure the crack is wide enough to accept the material. Hairline cracks don’t play well with the epoxy injection materials. The epoxy manufacturers will tell you the MINIMUM crack width.

Flat Roof Decks: A Bit Different

Whats the difference between a regular roof and a flat roof, and why does it require different material? The key is in the word flat. When a roof is flat water is going to spend a lot more time in one place giving it more time to find a way underneath the roof surface and into the structure. So rather than a roofing material that simply lets water run down it, you need a roofing material that offers a completely waterproof barrier. Hence why waterproof decking is popular. As a multi-ply PVC membrane, vinyl surfaces can hold up to the rigors of continued exposure to water, heat, wind, etc.

    Tip #3 Regular Professional Maintenance

    Time and again, we would like to emphasize the need to regularly conduct maintenance. You should schedule this at least twice a year. Apart from the usual inspections and cleaning, there are far more extensive maintenance procedures. Buildings are usually high and large which make them difficult to access especially if you are not trained to do so. Because of these reasons, you should have a commercial roofing partner to monitor and study your concrete roofing structure. You have to report all roofing-related concerns that you may have so that they can address it properly.

    There is nothing wrong in involving yourself in roof repair projects. However, it should always be under the supervision of a roofing specialist. Always prioritize your own safety. Besides, professional roofers are always ready to assist you provided that they have the licenses to operate, tools, equipment, and appropriate skills.
