Rain reaches the roof
Roof surfaces collect large volumes of rainwater, particularly during heavy storms and prolonged rainfall.

Rooftop Gutter and Downpipe Waterproofing Solutions.
Rooftop Drainage Protection
Roof Top Gutter, downpipe and water-flow protection
Gutters and downpipes are often ignored until there are serious problems with drainage and run-off.
At Liquid Rubber Coatings, we help protect the complete rooftop water-management pathway — from the roof surface and gutter channels through to downpipes, outlets and discharge points.

Water-flow pathway
Roof to ground
Roof Catchment
Rainwater is collected and directed toward drainage points.
Gutter Channel
Water must flow freely without leaks, rust or blockages.
Downpipe System
Collected water is safely carried away from the building.
Controlled Discharge
Run-off is released away from walls, foundations and structures.
One Connected System
Water must move somewhere.
A roof does not manage rainwater by itself. Gutters, outlets, downpipes and discharge points must all work together as one continuous system.
Water enters gutters and channels
Gutters must remain clear, correctly sealed and capable of handling the volume of water flowing from the roof.
Downpipes carry water vertically
Downpipes move water away from roof level. Blockages, damaged joins or poor connections can cause overflow and uncontrolled run-off.
Run-off leaves the building safely
Proper discharge helps protect walls, landscaping, foundations and surrounding structures from repeated water exposure.
Drainage Failure Map
Small rooftop drainage failures can create damage far below the roofline.
Gutters and downpipes are often ignored until water begins overflowing, leaking into the building or damaging walls and surrounding areas.
Blocked or undersized gutters
Water can overflow during heavy rain and run back toward the roof,
fascia or building interior.
Leaking joins and outlets
Failed seals, rust and movement can allow water to escape before it
reaches the downpipe.
Damaged or disconnected downpipes
Uncontrolled water discharge can affect walls, foundations,
pathways and landscaping.
01
The First Warning
Drainage problems rarely remain drainage problems.
Once water stops following its intended path, it can enter ceilings, damage fascia boards, stain exterior walls, affect foundations, accelerate corrosion and create mould or damp conditions. Maintaining the rooftop drainage pathway is therefore part of protecting the entire building.
Rooftop Water Management
Protection designed around the complete drainage pathway.
Rather than treating an isolated leak without understanding its cause, the rooftop drainage system should be reviewed as a connected network.
Primary Objective
Keep water moving away from the building.
Gutters and downpipes are designed to collect, control and redirect rainwater. Waterproofing, sealing and maintenance help preserve this pathway and reduce the risk of uncontrolled run-off.
Gutter waterproofing and sealing
Helps seal vulnerable joins, outlets, laps and problem areas where water can escape.
Downpipe connection protection
Addresses connections and transition points where movement, deterioration or poor sealing can cause leaks.
Rust and corrosion management
Protects metal drainage components from continued moisture exposure and environmental deterioration.
Overflow-risk assessment
Reviews visible drainage behaviour, water paths and areas where run-off may be entering or damaging the property.
Inspection Journey
Follow the water. Find the weakness. Restore the flow.
Effective rooftop drainage work begins by understanding where the water comes from, where it should go and where the system is failing.
01
Inspect
Review gutters, downpipes, outlets, joins and visible water paths.
02
Trace
Identify how water travels across the roof and through the drainage system.
03
Prepare
Clean and prepare vulnerable surfaces so repairs and coatings can bond correctly.
04
Seal
Address leaking joins, outlets, cracks and deteriorated drainage components.
05
Protect
Apply the recommended waterproofing protection and restore controlled water flow.
Why It Matters
Your rooftop drainage system protects more than the roof.
Gutters and downpipes help protect ceilings, walls, foundations, landscaping and the surrounding property. Maintaining this system reduces the chance that ordinary rainfall becomes an expensive building problem.
Reduces uncontrolled roof run-off
Helps keep rainwater within its intended drainage pathway.
Protects walls and ceilings
Reduces water overflow and leakage near the building envelope.
Helps prevent corrosion
Protects vulnerable metal drainage components from moisture
damage.
Supports long-term roof performance
A functioning drainage system helps the roof manage severe
weather more effectively.
Reduces avoidable repair costs
Early attention can prevent minor drainage issues from becoming
major property damage.
Rooftop Drainage Assessment
Do not wait for overflow to reveal the problem.
Gutters and downpipes are often ignored until there are serious problems with drainage and run-off. A professional assessment can help identify vulnerable areas before water causes expensive damage.
