Flat Concrete Slab & Waterproofing is a residential building-planning choice in the Price Your Build estimator. The roof selection affects span limits, support spacing, drainage, light transmission, heat gain and maintenance.
What this option means
The roof selection affects span limits, support spacing, drainage, light transmission, heat gain and maintenance.
Why it affects the estimate
The estimator uses this selection to establish an early allowance. Final cost depends on the approved drawings, site conditions, supplier system, installation method and contractor scope.
Before proceeding
- Confirm roof fall, guttering, flashing, wind exposure and compatibility with the supporting frame.
- Compare the final specification, exclusions and installation detail against supplier and contractor quotations.
- Confirm the relevant professional, municipal and product requirements for the actual project.
