Why commercial roofs fail differently to houses
A blocked residential gutter overflows outside the wall. A blocked commercial box gutter does the opposite: water rises inside the roof plane until it passes the internal upstand and runs into the ceiling space. That is why a single missed clean on a Sydney warehouse or a Newcastle retail strip can produce a five-figure stock and fit-out claim while the roof itself is undamaged.
The other difference is scale. Long box gutter runs with a single sump concentrate everything the roof collects into one outlet, and low-pitch metal roofs shed debris slowly, so silt compacts rather than washing through. Clearing that properly needs vacuum equipment and roof access planning, not a ladder and a bucket.
What a commercial gutter clean includes
- Site-specific SWMS and height safety plan
- Full box gutter, eaves gutter and valley clearing
- Sump, rainhead and downpipe flushing
- Industrial vacuum extraction, waste removed off site
- Overflow and flashing condition check
- Before and after photo report for your records
