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 provides a comprehensive assessment of the roof condition at the above address, including detailed observations, photographic documentation, and prioritised recommendations for maintenance and remediation.

Background

Weather: Upon arriving at site, the weather was clear with minimal winds. This remained consistent throughout the entire reporting process, allowing for thorough drone inspection and clear photographic documentation.

Access: Site access was facilitated by the property maintenance team. A comprehensive walk-around was conducted to identify areas of concern prior to the aerial inspection phase.

Scope: This inspection was commissioned to assess the overall condition of the roof system, identify any active defects or leak sources, and provide recommendations for the planned solar panel installation.

Total Roof Area

ROOF 1 ROOF 2 Service Main Building West Wing Service Tower

Schematic roof plan identifying inspection zones

The property comprises three distinct roof areas totalling approximately 1,850m². The main building (Roof 1) represents the primary commercial space, with the West Wing (Roof 2) housing additional facilities. The Service Tower provides plant room access.

Roof 1 — Main Building

Roof 1 covers the main commercial building and represents approximately 60% of the total roof area. The following items were inspected and assessed:

1
Roof Sheets — 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 estimate a remaining lifespan of approximately 5–10 years. Localised rust has developed beneath the downpipe spreader due to galvanic reaction between dissimilar metals.

2
Flashings — Entire Roof
Observation The flashings 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. Potential weak points exist at brick mortar junctions.

Eaves Gutters — Perimeter
Observation This roof uses an eaves gutter system that is performing adequately. No defects have been noted in relation to the gutters. They appear to have been replaced in recent years and are in good condition.

Penetrations — Various Locations
Observation This roof has several penetrations including roof safety anchor points. These have been installed according to industry standards, are not currently the cause of any leaks, and are not a point of concern.

Roof 2 — West Wing

The West Wing roof exhibits similar conditions to the main building, with the primary concern being the box gutter system which shows signs of inadequate drainage capacity. Full inspection details available in the complete report.

Roof 3 — East Wing

The East Wing is generally in satisfactory condition but nearing end of functional lifespan. Box gutters show poor joins and inadequate fall. Full inspection details available in the complete report.

Conclusion

The overall condition of this roof is satisfactory for its age; however, due to its age and the planned installation of solar panels, a full roof replacement is recommended to support this upgrade.

Roof 1 — Main Building 4/10

Generally satisfactory. Localised rust requires rectification. Flashings show past repairs. Budget for fascia replacement.

Roof 2 — West Wing 3/10

Box gutter system is primary concern. Penetrations need back-trays. Downpipes causing galvanic corrosion.

Roof 3 — East Wing 5/10

Nearing end of lifespan. Box gutters have poor joins. Wall cladding adequate but stone should be capped.

Service Tower 7/10

Concrete roof with membrane. Minor pooling observed. Continue monitoring annually.

Recommendations Summary

Priority Item Action Required
High Box Gutter System Replace with adequately sized system
High Penetration Back-Trays Install to bring to compliance
Medium Flashings Budget for full replacement
Medium Fascia Board Replace or cap deteriorated timber
Medium Downpipes Replace copper with compatible material
Low Roof Sheets Monitor annually, budget for 5-10 year replacement

Solar Panel Installation: Given the current roof condition and estimated remaining lifespan, we recommend completing roof replacement prior to solar installation to ensure the long-term effectiveness of both investments.
