Why the whole drainage path matters
Gutter profile, roof catchment, fall, outlets, overflow provisions, downpipe number and downstream discharge all influence roof-drainage performance.
Factors worth checking
- Roof catchment, pitch and drainage layout
- Gutter profile, condition, capacity and fall
- Outlet, rainhead and overflow arrangements
- Number, size and route of downpipes
- Fascia condition and adjoining roof-edge details
- Access for safe future maintenance
Cairns weather preparation
Queensland SES advises keeping gutters and downpipes clear so water can drain away quickly during cyclones and storms. Maintenance should be completed safely and ahead of severe weather.
