Typical project sequence
- Inspect and measure the existing roof
- Confirm material, colour and system specification
- Resolve approval, engineering and access needs
- Coordinate solar, electrical and other services
- Protect the site and establish safety controls
- Remove the existing covering in planned stages
- Inspect substrate and approve variations
- Install support, underlay and insulation layers
- Install new roof, flashings and rainwater details
- Complete checks, clean-up and documentation
Weather planning
A roof replacement opens the building. Work stages should respond to forecasts and the area that can be made weatherproof within the working period.
Variations after strip-off
Some substrate defects cannot be confirmed until removal. A clear process should define evidence, pricing and approval before additional work proceeds.
