Common Signs of Roof Leakage
- Mould or mildew growth
- Peeling paint or wallpaper
- Damp, musty odours from hidden leaks

If you notice these signs, arrange an inspection to check where the water is entering and what roof repair or waterproofing work is required.
Common Causes of Roof Leakage
Damaged Roof Waterproofing
A damaged or worn waterproofing membrane can allow rainwater to penetrate the roof surface and enter the building below.
Water Stains and Leakage on Ceilings
Roof leakage can travel through the structure and appear as water stains, damp patches or dripping water on the ceiling below.
Cracks in Roof Surfaces
Cracks in concrete or other roof surfaces can allow rainwater to enter during wet weather.
Blocked Gutters and Poor Drainage
Blocked gutters or poor roof drainage can cause rainwater to collect and increase the chance of water seepage around the roof area.
Damaged Roof Joints and Sealing
Damaged sealing around roof joints and other openings can allow rainwater to enter through weak points.

Our team will inspect the affected roof area to identify the possible source of the leakage before recommending the repair or waterproofing method required.
Roof Leakage Repair and Waterproofing Methods
The repair or waterproofing method will depend on the source of the roof leakage and condition of the affected area.
Non-hacking waterproofing methods may be used for suitable roof leakage problems where major removal of the existing surface is not required.
PU Injection and Crack Sealing
PU injection or crack sealing may be used for suitable cracks where water is entering through concrete surfaces or joints.
Roof Waterproofing Membrane
A waterproofing membrane can be applied to suitable roof areas to form a barrier against rainwater penetration.
Roof Joint and Sealing Repair
Damaged joints and sealing can be repaired where they are identified as the source of the roof leakage.
Roof Drainage and Gutter Repair
Roof drainage and gutters can be checked where blocked drainage or water pooling is contributing to the leakage problem.
Roof Leakage Inspection
A roof leakage inspection helps us check the roof surface, cracks, waterproofing membrane, joints, gutters and drainage for possible sources of water leakage.
After checking the affected area, we will recommend the roof repair or waterproofing work required and provide a quotation based on the condition of the roof.
