Melbourne Protective Coatings was engaged by a body corporate to deliver a long-term roof waterproofing solution for a centrally located commercial building experiencing persistent leaks.
A building on Little Bourke St. in Melbourne CBD had leaks across the roof area, mainly from rusty gutters and skylight seals.
They were advised by different companies to replace the roof and have been quoted over half a million dollars for it, which is financially unviable and highly disruptive.
Multiple weakened fixings and lifted roof sheets required stabilisation before any coating could be safely applied.
Limited edge access meant live edge rails and elevated platforms were essential for safe navigation across the roof.
Deliver a neat, consistent Monument colour across the roof
Box gutters were deteriorated and actively leaking, requiring sealing and reinforcement prior to installing the Noxyde system.
These conditions required a structured approach to preparation so the final membrane would bond correctly and deliver long-term protection.
Rather than replacing the roof, MPC designed and installed a waterproofing roofing membrane system that delivered long-term performance at less than one-third of the replacement cost.Â
The solution provided a defect liability period of up to 20 times longer than the re-roofing alternative. It also allowed the project to be completed quickly with minimal disruption.
High-pressure cleaning of all roof surfaces
Re-tensioning and fastening of loose roof sheets and fixings
First full coat of waterproofing membrane
Advanced specialised tape installation where required
StormShield Essentials & StormShield Plus waterproofing across the entire roof
Second full coat of waterproofing membrane
Our team used specialist equipment and tools ensured safe access and thorough surface preparation:
Used for deep cleaning of the roof surface, removing dirt, contaminants, loose coatings, and corrosion. This step ensured optimal adhesion of the waterproofing membrane.
Enabled controlled, consistent, high-build application of the Noxyde Anti-Corrosion Waterproofing Membrane across large roof areas, ensuring uniform coverage and membrane thickness.
Provided safe and efficient access to restricted and hard-to-reach sections of the roof, enabling full coverage and correct installation of the waterproofing system without disruption to the building.
Installed around the full roof perimeter to create a safe working zone. This allowed our team to work confidently at height while maintaining strict safety compliance in the Melbourne CBD.
We used Noxyde Anti Corrosion Waterproofing Membrane to form a flexible, high build barrier that handles roof movement and resists water ingress.
Advanced specialised tape was applied where extra reinforcement was needed across seams, joints, and penetrations.
Noxyde is a high-build elastomeric membrane designed for long-term corrosion resistance, waterproofing, and rust stabilisation on metal roofs.
Its direct-to-rust adhesion, 200% flexibility, and ability to seal small cracks make it ideal for aging commercial roofs where replacement would be costly or disruptive.
The seamless membrane forms a durable protective barrier that stops ongoing corrosion, prevents leaks, and extends the overall service life of the roof.
The building now has a fully waterproofed roof with all leaks resolved, without the cost or disruption of a full roof replacement.Â
The body corporate received a durable, long-term solution delivered efficiently in a challenging CBD environment, extending the roof’s service life and providing ongoing protection and peace of mind.
