If you’re roofing in Hermanus or the greater Overstrand, choosing the right roof sheeting—and the right supplier—can save you time, money, and callbacks. Here’s your practical guide to IBR vs corrugated, when to choose each, what “cut-to-size” means, and proven tips for coastal wind and corrosion.
What is roof sheeting and what are my options?
- Corrugated roof sheets: Classic S-profile waves that shed water well and flex slightly in high winds. Great for residential homes, cottages, and outbuildings.
- IBR roof sheeting: Deeper, wider rib profiles that deliver higher load capacity and a modern look. Often preferred for light commercial, garages, and larger spans.
Build it Hermanus stocks SABS-approved corrugated and IBR roof sheeting with all the accessories you’ll need—and can cut to your specific lengths for a cleaner finish and less wastage. Standard lengths are also available if you prefer. See: Products > Roofing Materials on our site for details (source: Products).
IBR vs Corrugated: how to choose in Hermanus
- Wind exposure: Both profiles work, but IBR’s deeper ribs offer excellent rigidity on larger spans; corrugated’s flexibility helps disperse gust loads on smaller roofs.
- Aesthetic: Corrugated gives a classic coastal look; IBR a contemporary, linear profile.
- Span and structure: For longer spans or fewer purlins, IBR often wins; for smaller roofs and canopies, corrugated is cost-effective and quick.
- Budget: Corrugated can be the most economical for small to medium projects; IBR may reduce substructure costs on larger spans.
Why cut-to-size matters
- Less wastage: Order only the lengths you need for your roof plan.
- Faster install: Fewer cuts on site; cleaner overlaps and eaves lines.
- Better finish: Tighter fit at ridges, valleys, and barges.
Roof accessories you’ll likely need
- Fasteners and washers specified for your sheet profile
- Flashings (ridge, barge, side and end laps)
- Underlay and insulation (Sisalation; also consider Aerolite/Isotherm for thermal/acoustic comfort)
- Gutters, downpipes, and water tanks for rainwater management
These accessories are supported by your broader product set: rainwater goods, insulation, and flat sheet categories (source: Products).
Coastal roofing tips for the Overstrand
- Specify corrosion-resistant finishes and fasteners suitable for sea air exposure.
- Use correct side- and end-lap seals to prevent capillary water ingress.
- Pay attention to purlin spacing per manufacturer spec to resist uplift.
- Include insulation/vapour barriers to reduce condensation under sheets.
- Plan your rainwater goods—oversize gutters/downpipes where heavy rainfall and leaf load are expected.
