Chromadek Roofing Sheets: IBR, Corrugated Profiles and Full Roof Allowance Guide
Guide Type: Buyer guide
A Chromadek roof-sheet planning guide for South African homes, covering profile, roof structure, insulation, flashings, gutters and solar coordination.
Quick answer
Chromadek is the colour-coated steel material used when roofing sheets are profiled. The finished roof cost depends on the chosen profile and coating together with the roof pitch, structure, insulation, flashings, gutters and penetrations.
How to compare the options
| Option | Best suited to | Include in the allowance |
|---|---|---|
| IBR-profile roof | A crisp, linear roof expression with appropriate support and drainage design. | Profile, sheet lengths, fixings, flashings, insulation and rainwater goods. |
| Corrugated-profile roof | A traditional corrugated appearance on a compatible roof form. | Profile, laps, pitch, fixings, edge treatment and acoustic control. |
Cost and planning checklist
- Do not change roof profile late without reviewing structure, pitch and flashings.
- Include valleys, barge details, skylights, penetrations and gutters in every comparison.
- Coordinate photovoltaic panels and roof penetrations before sheets are ordered.
