Roofing Sheets Compared: IBR Profile vs Corrugated Chromadek vs Concrete Tiles
Guide Type: Technical guide
Compare IBR, corrugated Chromadek-type sheeting and concrete roof tiles for South African homes, including structure, pitch, insulation, rainwater and detailing allowances.
Quick answer
Roof covering selection affects more than the visible finish. It changes roof pitch, framing or support assumptions, underlay and insulation, flashings, drainage, acoustic expectations and the approach to roof penetrations.
How to compare the options
| Option | Best suited to | Include in the allowance |
|---|---|---|
| IBR profile sheeting | A crisp, modern sheeted roof design with an appropriate support and drainage layout. | Profile, coating, fixings, flashings, insulation, noise and condensation control. |
| Corrugated coated sheeting | A familiar, rhythmic profile suited to the selected roof form. | Gauge, coating, laps, fixings, pitch, insulation and flashings. |
| Concrete tiles | A heavier, tiled roof appearance with established roof-tile detailing. | Roof structure, pitch, underlay, battens, hips, valleys and loading. |
Cost and planning checklist
- Design the roof covering and roof pitch together; do not substitute one late without review.
- Include gutters, downpipes, valleys, flashings, skylights, penetrations and insulation in comparisons.
- Verify the chosen product system and installation requirements with supplier documentation and the project professional.

Frequently asked questions
Are roof sheets always cheaper than tiles?
Not necessarily after roof shape, structure, insulation, flashing, sound control and finishing scope are compared.
Can I change the roof material after plans?
It should be reviewed rather than treated as a cosmetic change, because structure, pitch, drainage and approvals can be affected.
Important
Confirm the final product, scope, installation method, drawings, approvals and professional requirements for the specific site before committing to work.
