Signs You May Need Flat Roof Waterproofing

Here are common indicators that suggest it’s time for a professional flat roof waterproofing service:


  • Water Leaks: If you notice water entering your home through the ceiling or walls, it’s a clear sign that your flat roof’s waterproofing has been compromised.


  • Moisture Stains: Stains or discoloration on your interior ceiling or walls can result from water seeping through the roof membrane.


  • Blisters and Bubbles: The appearance of blisters or bubbles on your flat roof’s surface indicates trapped moisture beneath the membrane, a condition that waterproofing can address.


  • Cracks and Deterioration: Visible cracks or overall deterioration on the roof’s surface can create vulnerabilities, allowing water infiltration.


  • Pooling Water: Flat roofs should ideally drain water efficiently. If you notice water pooling or standing for extended periods after rain, it’s a sign of drainage issues that waterproofing can resolve.


  • Decreased Energy Efficiency: Rising energy bills due to temperature fluctuations inside your home can be a result of a poorly insulated or damaged flat roof, which waterproofing can help improve.
