Roof waterproofing is the process of applying materials or systems to roofing surfaces to prevent water penetration. It involves sealing joints, using membranes (sheet or liquid), coatings, flashing, sealants, and ensuring proper drainage. Waterproofing differs from simple roof repair because it provides a continuous barrier to moisture protecting roofs from weather exposure, leaks, and structural deterioration.
Stopping water ingress before it causes interior damage
Preventing mould, mildew, and rot in roofing structure and insulation
Extending roof lifespan and reducing maintenance costs
Enhancing energy efficiency by maintaining insulation performance
Protecting property value and making insurance claims easier
Water infiltration over time weakens roofing substrate, deck, and supports leading to costly and unsafe damage.
Leaks can damage ceilings, walls, insulation, and paint waterproofing protects your finishes and interior areas.
Moist, damp conditions foster mould and mildew which can affect indoor air quality and occupants’ health.
Sealed, waterproof roofs retain insulation effectiveness and prevent unnecessary heating or cooling load, making interiors more comfortable and energy usage lower.
Roof Inspection & Surface Assessment – Evaluate existing roof condition, membrane type, slope, penetrations and previous damage.
Material & System Selection – Choose appropriate waterproofing system (liquid membrane, sheet membrane, coatings) suited to roof type and exposure.
Surface Preparation – Clean, repair cracks, ensure good substrate condition and remove old coatings or debris.
Application of Waterproofing System – Apply membrane or coating evenly, ensure flashing, joints and roof penetrations are sealed properly.
Quality Assurance Tests – Check for leaks, ponding, correct adhesion, and waterproofing integrity.
Final Inspection & Warranty – Complete final checks, clean up, and provide guarantee for both materials and workmanship.
We waterproof a wide variety of roofing systems, including:
Flat & Low-Slope Roofs – membranes, coatings or sheet systems to manage ponding and ensure drainage.
Concrete & Terracotta Tile Roofs – waterproof coatings, sealing of tiles, flashing integrity to block moisture entry.
Metal & Colorbond Roofs – sealants, coatings, and membranes to protect seams, flashings, rust-prone areas.
Composite & Synthetic Roof Systems – bespoke waterproofing solutions fitted to panel joints and penetrations.
If you notice any of the following, roof waterproofing may be required:
Water stains or discoloration on ceilings or attic spaces
Leaks during rain or storms, often after heavy downpour
Cracks in roof surface, tiles, or around penetrations
Peeling, blistering or flaking in existing coatings
Ponding water or pooling on flat or low-slope roofs
Damp insulation or mould in roof cavity
Corrosion, rust or degraded sealant joints
Flashing around vents, skylights and chimneys failing

Yes it can, especially when leaks are due to surface failure or faulty flashing. But in some cases repair or restoration of damaged roof substrate may also be needed.
Depends on the system and conditions, often 7-15 years for coatings or liquid membranes, longer with sheet systems and good maintenance.
Yes. Tiles or metal surfaces alone often allow moisture entry through joints, flashing or underlay; waterproofing adds protection.
There’s an upfront cost, but it often prevents much bigger costs later from water damage, leaks, mould, and structural decay.
