Reliable roof waterproofing for long-lasting protection
Protect your building's structural integrity, prevent costly emergency repairs, and maintain property value with roof waterproofing solutions.
Why do roofs leak?
Roof leaks are common in Melbourne apartments and commercial buildings. Poor drainage, weather damage to membranes, substandard installation, and building movement can compromise waterproofing systems over time.
Insufficient drainage
Buildings without adequate drainage systems experience water pooling after rainfall. When water cannot properly drain from roof surfaces, it finds alternative routes through the building structure, causing damage and deterioration often to apartments below.
Environmental damage
UV radiation, temperature fluctuations, and weather gradually compromise waterproofing membrane performance. These environmental factors cause material breakdown, including cracking, splitting, and membrane failure, leaving buildings vulnerable.
Poor quality materials and installation
The waterproofing membrane is the primary defense against moisture infiltration. Using uncompliant materials or improper installation techniques leads to premature system failure and requires expensive repairs.
Building movement and joint failure
Melbourne's climate causes buildings to expand and contract with temperature changes. This constant movement compromises seals around roof penetrations and construction joints, creating entry points for water infiltration.
Annual roof inspections help identify water damage and membrane deterioration early, preventing minor issues from becoming costly major repairs.
Why you should care
We've seen minor roof leaks in Melbourne quickly escalate into major building failures costing property owners hundreds of thousands in repairs, insurance disputes, and body corporate heartache.
Compounding structural damage
Roof leaks penetrate building systems, compromising structural integrity through concrete degradation, steel corrosion, and widespread mould across multiple apartments and levels.
Emergency repair costs
Roof system failures necessitate immediate intervention, often requiring substantial emergency funding and special levies costing many thousands of dollars when multiple units and common areas are affected.
Insurance complications
Water damage claims can face complications when maintenance records are inadequate or when damage is classified as gradual deterioration rather than sudden damage.
Legal liability
Property managers bear legal responsibility for common area roof maintenance. Resident property damage can trigger liability disputes, building defect claims, and litigation, compromising both financial position and professional reputation.
Spot the warning signs
Recognise failed waterproofing systems and water intrusion signs early to prevent costly and disruptive repairs.
Ceiling water marks on upper floors: Stains, discoloration, mineral deposits, or paint deterioration on top-floor ceilings or adjacent walls typically signal water entering from above. Examine areas directly beneath rooftop sections and shared hallways for signs of water damage.
Water pooling on the surface: When water remains pooled on rooftop surfaces long after rainfall, this suggests an improper fall toward drains or blocked drainage systems. These puddles will eventually penetrate through even small imperfections in the roofing membrane.
Membrane damage and surface deterioration: Cracking, blistering, or peeling waterproofing membranes indicate system failure. Look for exposed substrate, torn membranes around penetrations, or areas where the membrane has pulled away from walls.
Internal moisture and mould issues: Residents reporting persistent dampness, musty odours, or mould growth in top floor units can signal roof leaks. These symptoms suggest water is penetrating through compromised waterproofing systems.
Additional signs to watch for: Rust stains around roof penetrations, loose or damaged flashing, or peeling/blistering paint in dwellings directly below the roof, can indicate roof waterproofing failures.
Early detection of these signs allows for preventive repairs before costly damage and repairs are required.
The Schaefer solution
Trust Schaefer Waterproofing to fix your leaking roof right – the first time. Our comprehensive waterproofing service meets Australian Waterproofing Standards, ensures long-lasting protection, and provides documentation of installation from start to finish.
1.
Assessment and solution design
We assess your roof for water damage using non-destructive testing methods. We identify fall or drainage issues, waterproofing failures, and structural vulnerabilities, providing solutions compliant with Australian Waterproofing Standards AS 4654.1-2012.
2.
Waterproofing system selection
We recommend the most suitable waterproofing system for your roof, considering factors like building height, weather exposure, traffic requirements, and budget constraints. Waterproofing membranes should be UV resistant if remaining exposed, ensuring long-lasting protection.
3.
Surface preparation
Existing failed membrane and screed is removed by grinding and jackhammering. Damaged substrates are repaired or replaced. The surface is then cleaned, prepared, and primed for optimal adhesion of the new membrane.
4.
Waterproofing system installation
The membrane and waterproofing system is installed according to the Australian Waterproofing Standards AS 4654.1-2012 and technical specifications. Photo and video evidence of detailing and installation is provided. If required, a screed is installed to create a proper drainage fall for optimal water escape (min. 1:100) before the membrane is applied.
5.
Penetration and detail work
All roof penetrations, expansion joints, and parapet walls are properly sealed with compatible materials. Flashing systems are installed to direct water away from critical areas.
6.
Testing
We conduct thorough flood testing and drainage checks to verify system effectiveness. The option for independent third-party testing provides additional quality assurance.
7.
Project handover
We handle the project from beginning to end. Warranty and compliance certificates are provided, and we schedule a follow-up maintenance visit in 6-12 months time to ensure ongoing performance.
