Start with what you can see
Make notes from a safe position. The purpose is to give a roofer a useful starting point, not to diagnose the structure yourself.
- Where the overflow or leak happens
- Blockages, fallen joints or sagging runs
- Downpipe condition and safe access
What a written proposal should cover
Ask providers to explain the work in the same level of detail. A cheaper price can reflect a narrower scope.
- Inspection and clearing where appropriate
- Joint, bracket, seal or section repairs
- Flow test and explanation of any remaining issue
Questions worth asking
- Is the fault in the gutter or the downpipe?
- Can a section be repaired instead of replacing the run?
- How will flow be tested after the work?
Cost and comparison
Access, gutter length and height, material, blockage and damaged sections influence the price.
