Roof Inspection Report
A damaged or aging roof can lead to costly repairs, water damage or structural issues. Our expert roof inspections identify hidden weaknesses – whether from storms, general wear or poor drainage – so you can fix them before they escalate. We’ll provide a detailed report with practical solutions to keep your roof in tip-top shape.
For commercial properties in Australia, regular roof inspections are not just recommended—they’re essential. Given the larger surface area and the increased complexity of commercial roofing systems, it’s advised to inspect your commercial roof twice a year: autumn and spring, to prepare for summer/winter storms and to assess any damage from previous storm season.
Regular inspections help identify and address issues like water pooling, membrane damage, and blockages in drainage systems, which are common problems in commercial roofs.
Why it matters:
Prevents costly water damage and structural issues
Identifies wear and tear before storm season
Ensures rainwater harvesting systems remain effective
Who needs it?
Homeowners and businesses looking to protect their investment
Properties needing to meet safety and maintenance standards
Anyone wanting to reduce long-term repair costs

When do I need it?
Commercial: at least annually
Residential: Recommended every 3-5 years
Before and after extreme weather events, such as storms
Before purchasing or leasing a new property
When planning major renovations
