Our Rooftop Waterproofing Process
Before waterproofing on rooftop begins, we evaluate its condition — checking for cracks, pooling water, drainage issues, and existing damage.
Surface Preparation:
Clean the roof thoroughly by removing dirt, dust, oils, and any loose materials. Repair cracks, damaged areas, seal joint, and ensure proper slope for water drainage.
Primer Application
Apply a primer coat to improve adhesion between the roof surface and the waterproofing layer. Different primers are used depending on the surface type (concrete, metal, or asphalt).
Waterproofing Installation:
Liquid Membrane-Applied by brush, roller, or spray, forming a seamless waterproof coating.
PU (Polyurethane) Coatings-Flexible and UV-resistant, ideal for roofs exposed to sun and movement..
Inspection & Quality Check:
Perform water ponding tests to ensure no leakage. Inspect adhesion, coverage thickness, and detailing.

Frequently Asked Questions
What types of roofs can be waterproofed by SuperiorWaterproofing company?
We service concrete flat roofs, metal roofs, roof deck, and roof terrace. Each roof type requires a different waterproofing membrane or coating, which our team will recommend based on your property condition.
How long does roof terrace waterproofing last?
With correct rooftop installation and a proper roof terrace waterproofing process, the system can last 10–20 years, depending on the membrane type and exposure to Queensland’s climate.
Is your system for waterproofing of rooftop compliant with Australian Standards?
Yes, our system for waterproofing for rooftop is fully compliant with Australian Standards. We use high-performance membranes and installation methods that meet strict industry requirements, ensuring long-term durability, safety, and protection against Queensland’s harsh climate conditions.
How much does concrete rooftop waterproofing cost on the Gold Coast and Brisbane?
Costs vary depending on roof size, condition, and membrane type. On average, rooftop waterproofing can range from $50–$120 per square metre. We provide free quotes tailored to your property.
How to choose the best rooftop waterproofing near me?
How soon can I use the house after concrete roof deck waterproofing is completed?
Most systems require 24–48 hours curing time, though some may take longer depending on the weather and membrane type. We’ll provide clear guidance so you know when it’s safe to use after roof deck waterproofing.
What are the most common methods for waterproofing rooftop terraces?
The choice depends on the terrace usage (e.g., foot traffic, tiling, or a green roof). Common methods include:
- Liquid-Applied Membranes: Seamless coatings that cure into a rubber-like layer.
- PU (Polyurethane) Coatings: Highly UV-resistant and durable for exposed areas.
- Bituminous Membranes: Traditional “torch-on” felt layers.
- Cementitious Coating: Often used under tiles for rigid protection.
Can the waterproofing roof terrace, balcony, & roof deck be applied over existing tiles or concrete?
Yes, roof terrace waterproofing 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.
Does roof terrace waterproofing or under deck waterproofing improve energy efficiency?
Yes—waterproofing a roof terrace 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.
Should waterproofing of rooftop in Brisbane or Gold Coast be done by licensed professionals?
Yes. Professional contractors ensure waterproofing of rooftop in Brisbane or Gold Coast complies with Australian Standards and local building requirements, delivering reliable and long-lasting results.
