Roof Condition Report

Commercial Office Complex — Sydney, NSW

Report Date February 2026
Reference CAM-2026-SAMPLE
Compiled By Combined Asset Management
Inspection Type Drone & On-Foot

Introduction

At Combined Asset Management, we provide expert roof and façade cladding reports and advice. We specialise in all aspects of roofing — Tile, Metal, Slate, Zinc, Copper, and Lead — specifically targeting heritage, commercial and high-end residential clients with multiple building portfolios.

This report documents the current condition of the roof, identifies defects requiring attention, and provides prioritised recommendations for maintenance and rectification works.

Background

Weather: Upon arriving on site, the weather was clear with minimal winds. This remained consistent throughout the entire reporting process, allowing for comprehensive drone coverage and clear photography.

Access: We conducted a full inspection using both drone technology and on-foot assessment where safe access permitted. All roof areas were documented and photographed systematically.

Roof Summary & Details

Roof Design Multi Pitched Metal Roof
Roof Material Colorbond Steel
Roof Profile Longline 305
Roof Pitch Varies (5° – 15°)
Roof Height Multiple Storey
Rainwater System Eaves and Box Gutters
Estimated Roof Age 25 – 30 years
Overall Current Condition 5/10
Poor Excellent

Upon conducting the inspection, it became apparent that the overall condition of the roof is satisfactory for its age. However, certain areas exhibit significant defects that require attention. These specific defects have been outlined comprehensively below.

Observations & Findings

The following findings detail the condition of key roof elements. Each item includes location, observations, photographic evidence, and our recommendation.

1 Roof Sheets
Budget for Rectification
Location Entire Roof Observation The roof is covered with Longline profile sheets, most of which appear to be in relatively good condition given the roof's age. While the sheets are satisfactory, we suggest they have a lifespan of around 5–10 years remaining. Rust has developed beneath the downpipe spreader due to the dissimilar metals of the downpipe and sheet. To bring this roof to standard, it is recommended this area of rust is replaced. Recommendation Budget for rectification of rusted areas. Monitor and inspect annually to track deterioration.

2 Flashings
Budget for Replacement
Location Entire Roof — Ridge, Valley & Perimeter Observation The flashings occupying Roof 1 are in 'okay' condition and are not the current obvious cause of any leaks. The age of this roof is evident through the flashings — previous 'band-aid' repairs have been made, indicating previous points of defect. Note that circled flashings outline potential weak points at the brick mortar junctions. Whilst these are not currently an area of concern, leaks could arise here in the future. Previous pooling may have been a defect as multiple silicone repairs have been made to different areas; as these are band-aid repairs, leaks may arise again in the future. Recommendation Budget for full flashing replacement to ensure long-term performance. Monitor mortar junctions annually.

3 Eaves Gutters
Monitor Annually
Location Perimeter of Roof Observation This roof uses an eaves gutter system that is performing adequately. No defects have been noted in relation to the gutters. They should be monitored and inspected annually. The eaves looked to have been replaced in more recent years and are in good condition relative to the age of the roof sheeting. Recommendation No immediate action required. Continue to monitor and inspect annually. Ensure debris is cleared before storm season.

Conclusion

Roof 1 is in generally satisfactory condition, with longline profile sheets that have a remaining lifespan of approximately 5–10 years. However, localised rust beneath the downpipe spreader requires rectification to prevent further deterioration.

Flashings, while currently functional, exhibit evidence of past repairs and potential weak points at mortar junctions, which may lead to leaks in the future. The eaves gutters are in good condition and appear to have been replaced in recent years.

Recommendations Summary:

Budget for rust rectification and potential flashing replacement. Monitor and inspect flashings, gutters, and all roof elements annually. A detailed scope of work and budget aligned with this report can be provided upon request.
