How To Find The Leak On Your Concrete Roof.

Are concrete roof inspections necessary? YES. Concrete roof repairs and maintenance are definitely necessary because concrete is susceptible to cracks, scaling and flaking (also known as spalling) due to general wear and tear of the material mixture. Concrete is moderately porous, thus it is vital that adequate waterproofing systems are installed.

Before we discuss how to repair and waterproof a leaking concrete roof, we first need to ask the most important question: Where Is The Leak Coming From?

Firstly, we recommend that roof inspections only be conducted by professional roof waterproofing contractors like ourselves. However, if you are familiar with roofs you can perform a basic visual inspection yourself. Here is a list of roof leaking signs and symptoms that may be visible on your concrete roof:

  • 1. Ponding Water:

    Concrete roof systems are not designed to hold water. Period. Thus, if you notice ponding water that is NOT slowly evaporating or isn’t drained within 48 hours, you need to call our waterproofing professionals for a free no obligation quote.

  • 2. Downpipes, Outlets & All Other Roof Drainage:

    Are your downpipes or outlets blocked? You can test this by conducting a flood test. Firstly (with the help of someone) take a hose pipe up onto the roof with you. With the hose pipe connected to the tap on the one end, place the hose into or in direction of your downpipes and take note of any water backing up onto the roof. If you do experience water back up or any slow flow of water, there might be dirt or debris blocking your drainage. Therefore, it is time for some downpipe cleaning.

  • 3. Cracks, flaking, Scaling Concrete:

    These are all signs of concrete that has not been waterproofed as these are the general wear and tear symptoms of concrete. If this is the case, give us a call and we will happily answer any questions or queries you have regarding the waterproofing options for your concrete roof.

  • 4. Loose Waterproofing Laps:

    if your roof already has a torch on waterproofing system installed but you are still experiencing leaks, you need to ask yourself 2 important questions; When last was my roof waterproofing maintained? Who installed my waterproofing? Majority of roof waterproofing systems come with a maintenance guarantee.

  • 5. Holes, Tears Or Any Other Imperfections in Your Concrete Waterproofing:

    The majority of other tradesmen and the community overall do not understand how waterproofing works. And you shouldn’t need to, that is our job. Having said that, we sometimes find that other contractors (ie. electricians, plumbers, satellite installers etc) will damage the waterproofing accidentally whilst installing or completing the service they were hired to do. Thus, resulting in water ingress.

  • 6. Do NOT Restrict Your Leak Inspection To Only Above The Leak Area:

Concrete is permeable, remember. Therefore, water has the tendency to travel before finding its way out again. Concrete waterproof coatings and other membrane waterproofing can increase the likelihood of water travel if it is damaged. Thus, resulting in water seepage you will not be able to visibly see due to it being under the coating or membrane.

  • 7. Plumbing Pipe Leak:

    If your leak is constant regardless of the elements, you might have a plumbing problem more so than a waterproofing problem.
