## Project details

## Scope of work

Project Overview: Comprehensive remediation of a residential roof system to resolve active water penetration and structural damage.

Key Deliverables:

Detailed Roof Leak Detection: Conducted a full assessment to locate entry points caused by weathered roofing components and deteriorated seals.

Rusted Flashing Replacement: Removed aged, corroded roof flashings and installed new, heavy-duty lead or Colorbond flashings to ensure watertight roof-to-wall transitions.

Box Gutter Restoration: Repaired the damaged box gutter system, clearing blockages and re-sealing joints to restore optimal stormwater drainage and prevent internal flooding.

Roof Plumbing Maintenance: Inspected all roof valleys and downpipes to ensure the entire water catchment system is fully functional and compliant.

Final Waterproofing & Testing: Applied high-grade roofing sealant and conducted water flow testing to verify the integrity of the Kogarah roof repair.

## The challenge

The client was facing a severe leaking roof that threatened the property's structural integrity. The primary issues were rusted flashings that had lost their water-shedding capability and a damaged box gutter causing water to back up and overflow into the building. Previous temporary fixes had failed, necessitating a professional, long-term roofing solution.

## The outcome

We successfully restored the roof’s watertight seal by replacing all corroded metal flashings and rebuilding the box gutter drainage system. This project eliminated all active leaks, improved stormwater management, and provided the homeowner with peace of mind. The property is now fully protected against harsh weather conditions with durable, high-quality roof plumbing.
