Rooftop Waterproofing Brisbane & Gold Coast

The  liquid waterproofing membranes are ideal for waterproofing of roof top, roof decks, balconies, and terraces, offering a seamless and flexible barrier that bridges cracks effectively. These systems require thorough surface preparation and skilled workmanship to ensure long-term performance.

A specialized variant, polyurethane liquid membrane, is particularly suited for flat roofs and exposed areas. Applied in multiple coats, it delivers exceptional flexibility and weather resistance, making it a reliable choice for harsh outdoor conditions. Both systems provide robust protection when installed correctly, enhancing durability and moisture control across a range of surfaces including waterproofing concrete slab roof and roof deck.

Yes, waterproofing of rooftop can be applied over existing tiles or concrete, but only if the surface is properly assessed and prepared. This approach is often used in retrofit projects or when full removal isn’t feasible due to cost or access.

Yes—waterproofing a rooftop or under-deck area can contribute to energy efficiency, though it’s often an indirect benefit.

1. Reduces Heat Transfer
– Liquid-applied membranes and reflective coatings (like cool roof systems) can reduce solar heat gain, keeping interiors cooler.
– This lowers reliance on air conditioning, especially in hot climates like Queensland.

2. Protects Insulation Layers
– Waterproofing prevents moisture intrusion that can degrade thermal insulation.
– Dry insulation retains its R-value (thermal resistance), helping maintain stable indoor temperatures.

3. Improves Air Sealing
– Under-deck waterproofing systems often seal gaps and joints, reducing drafts and air leakage.
– This minimizes energy loss and improves HVAC performance.

4. Extends Roof Life = Less Embodied Energy
– A well-maintained waterproofed roof lasts longer, reducing the need for frequent replacements.
– Fewer materials and construction cycles mean lower overall energy footprint.
