Commercial Roofing
Your first step to NetZero with up to 90% heat-reflective coatings
Waterproof Your Commercial Roof
Is your roof rusty, leaking, or both? Don't replace it. Seal it with the RTT system for as little as a third of the cost of a replacement. We have manufactured our products in Australia since 2008: a top-quality waterproofing sealant and a NetZero Coating UV-protection topcoat membrane, available in any Colorbond colour.
Our specialist applicators waterproof and restore commercial roofs, including box gutters.

Benefits of going NetZero
Why Is Your Roof Overheating?
☀️ Sun Exposure:
Prolonged exposure to harsh sunlight causes your roof to absorb and retain heat, warming the entire structure from the top down.
🧱 Outdated Protection:
Traditional coatings and aging insulation fail to reflect solar radiation, forcing your HVAC system to work harder just to keep up.
💸 Higher Energy Bills:
That excess heat doesn't just make you uncomfortable—it drives up your power costs and carbon footprint.

Why seal your commercial roof instead of replacing it:
- Saves tens of thousands of dollars.
- Heat reflection and UV protection from our NetZero Coating.
- No costly building inspectors.
- You don't need to shut down your business. We apply the system while you keep trading.
- All leaks sealed, with a minimum 10-year warranty and options for 15+ years.
- Lower cooling costs. The topcoat reflects up to 90% of the sun's heat, so the building stays cooler.

COMMERCIAL ROOF LEAKS & ROOF REPAIRS
Most roofing specialists charge around $1,500 + GST for a small repair, and the price climbs considerably for bigger jobs. RTT Sealant charges 20% less, so the larger the job, the more you keep in your pocket.
Commercial Box Gutters
The average price is around $250–$300 + GST per linear metre. RTT Sealant charges $150–$200 + GST per linear metre, up to 40% less.
Commercial Metal Roof Restoration
Re-roofing costs $200–$300 + GST per m², and vacating the premises while it's done can cost tens of thousands of dollars in lost income. Our price can be as low as $80 + GST per m², and we finish within 3 weeks. If your roof is rusty, cracked, has holes or has loose screws in the sheets, our waterproofing system can seal it, whether it's on a business, hotel, shopping centre, government building or airport. Our own experienced specialists apply the products, and we have a long-standing reputation in the industry.
Commercial Concrete Roof Restoration
Valued at over $200 + GST per m², our current price is only $140 + GST per m². A concrete roof needs a different approach from a metal roof. The prep work requires a specialist to repair cracks, joins and holes before the primer and our UV-protection topcoat go on.
