❓What is Roof Waterproofing?
Waterproofing is the treatment of a surface to prevent the passage of water under hydrostatic pressure or the process where a building component is made totally resistant to the passage of water and/or water vapor.
Our specialists are professionally trained in waterproofing which helps to prevent water from entering and is the long-term solution to prevent roof leak.
The conventional system of waterproofing involves ‘membranes’. This relies on the application of one or more layers of membrane (available in various types of materials: e.g. bitumen, silicate, PVC, HDPE, etc) that act as a barrier between the water and the building structure, preventing water ingress.
However, the membrane system relies on the perfect application, which has presented difficulties. As such, problems with the application or when the membrane does not adhere properly to the substrate can lead to leakages.
❗Common Signs of Roof Leakage
- Brown stains or peeling paint on ceilings or walls
- Visible cracks or sagging areas on your roof
- Dripping water during rainstorms
- Mold or mildew smell indoors
- Increased electricity bills due to insulation damage
