IBR sheeting and concrete tiles are both common roofing choices in Bloemfontein. Each has a different performance profile in the Free State climate.
Performance in Bloemfontein's climate
Bloemfontein's combination of severe hail, high UV, wide temperature swings and dry winters tests both roofing types differently. Hail is harder on tiled roofs - individual tiles crack and need replacement. IBR sheeting dents but rarely punctures from hail. UV degrades unpainted IBR coating over years, requiring periodic repainting. Tiles without maintenance develop lichen and algae growth that retains moisture and accelerates surface deterioration.
Lifespan and maintenance
A quality concrete tile roof, properly maintained, can last 40–50 years. IBR sheeting with a Chromadek finish has a design life of 25–40 years with periodic painting and fastener attention. Both require maintenance - tiles need repointing of ridge capping every 10–15 years, IBR needs rust treatment and repainting on a similar cycle. Neither is maintenance-free.
Weight and structure
Concrete tiles are significantly heavier than IBR sheeting. An existing structure designed for tiles can usually support them. Converting from tiles to IBR reduces the load on the structure significantly, which is sometimes an advantage in older buildings. Converting from IBR to tiles on an existing structure needs a structural check.
Which to choose
Tiles suit traditional aesthetics and are better suited to shallower pitches. IBR is faster to install, lighter, and handles a wider pitch range including very low slopes. For new builds, the choice is often architectural. For a re-roof on an existing structure, keeping the same material type is usually the most practical option unless there is a specific reason to change.
Frequently Asked Questions
Can I convert a tiled roof to IBR in Bloemfontein?
Yes. We do tile-to-IBR conversions. The lighter IBR reduces structural load and the installation is faster than relaying tiles. The batten spacing changes, so new battens are required.
Which roof type is better for hail in Bloemfontein?
IBR sheeting dents but rarely penetrates under hail. Tiles crack under hail impact, especially older brittle tiles. If hail frequency is a priority concern, IBR has the edge.
