Our Roof Waterproofing Process
Free On-Site Inspection & Quote
S&S Remedial provides a no-obligation, free on-site thorough inspection and written quote for concrete or flat roof waterproofing repair projects across Brisbane, Gold Coast, and surrounding regions.
When a concrete roof waterproofing has reached the end of its life—showing signs of persistent leaks, bubbling, cracks, or complete failure—a surface-level fix won’t do the job.
Primer Application & Roof Sealing
Apply primers, and install a new, high-performance waterproofing roof sealant designed to withstand extreme weather and UV exposure. This method provides a clean slate and is ideal for roofs with multiple layers of failed waterproof roof coatings or extensive water damage.
Surface Cleaning & Preparation
Remove all dirt, moss, algae, and debris using tools like pressure washers or stiff brushes. Repair any surface imperfections—such as cracks or holes—to create a clean, stable base for waterproofing.
Roof Waterproofing Membrane
Select an appropriate material—such as liquid waterproofing membrane, polyurethane, EPDM, PVC, or bituminous coating—based on roof type and local conditions. Apply the first coat evenly and add additional coats (usually two or more), allowing each layer to cure before the next is applied.
Repair Cracks and Weak Spots
Our rip-up and redo waterproofing of rooftop is a thorough process that starts with mechanical grinding to completely remove the existing roof waterproofing membrane and any delaminated material. This allows us to expose the bare roof slab for inspection and repair. We then address any cracks or structural weaknesses.
Curing & Final Inspection
Let the system cure fully per manufacturer guidelines. Conduct a detailed inspection and consider flood testing to confirm watertight integrity. Address any gaps or weaknesses discovered. It ensures long-term reliability, improved insulation, and a strong manufacturer-backed 10 year warranty.
What are the best waterproofing solutions for residential and commercial roofs?
Liquid-Applied Polyurethane Membranes
- Best for flat concrete roofs, parapets, balconies, roof decks

Sheet Membranes (Torch-On Bitumen or PVC/TPO)

Steel or Metal Roof Waterproofing (Sealants & Membranes)
- Best suited for corrugated metal or low-maintenance Colorbond roofs
