How to plan your roof sheeting budget in gauteng
Understanding the Material Costs
When searching for a roofing supplier in Gauteng, you will see a wide range of prices per meter. This is usually due to the thickness of the steel (measured in mm).
0.4mm (Economy): Often used for temporary structures or low-cost housing.
0.5mm (Industrial Standard): This is what RS Warehouse supplies. It offers superior hail resistance and structural integrity for carports and homes.
0.58mm (Heavy Industrial): Used for massive clear-span warehouses.
IBR vs. Corrugated: Which is Cheaper?
A common question we get when providing roofing estimates is about the profile difference.
Corrugated (S-Rib): The classic “wavy” look. It has a wider cover width (762mm), meaning you need fewer sheets to cover the same area.
IBR (Inverted Box Rib): The modern, square profile. It has a slightly narrower effective cover (686mm) but offers better water drainage on flat roofs (low slopes). Our calculator automatically adjusts the sheet count based on the profile you select, ensuring your quote is accurate.
Hidden Costs in Roofing Quotes
If you are comparing our estimate against a quote from a local hardware store, check the “consumables.” Many suppliers quote for the sheets but leave out the Class 3 Fasteners and Polycarbonate Lighting, or they supply cheap “contractor grade” screws that will rust in two years. Our estimator includes Class 3 screws by default because a roof is only as strong as its weakest fastener.
FAQ's
Q: How much does a carport roof cost in South Africa?
A standard single carport (3m x 6m) using 0.5mm IBR sheeting typically costs between R4,500 and R6,500 for the roof covering alone, depending on current steel prices. Use our calculator above for an exact figure.
Q: What is the best roof sheet for hail areas?
In Gauteng’s hail belt, we recommend 0.5mm Full Hard Chromadek® or Galvanized steel. Thinner 0.3mm sheets dent easily and can be pierced by large stones.
Q: Do you offer roofing on credit?
Yes. Roofsheeting Warehouse partners with PayJustNow to allow you to split your roofing material purchase into 3 interest-free payments, making it easier to manage your renovation budget.
