Colorbond Roofing Cost Calculator
Here’s a comprehensive table for estimating Colorbond roofing costs across different states, considering various factors such as roof size, roof pitch, Colorbond types, labor type, and additional services. Colorbond is a popular roofing choice in South Africa and Australia due to its durability, low maintenance, and weather resistance.

| KwaZulu-Natal | +5% – +10% on labor and material costs | Moderate-cost region with a mix of urban and coastal influences. | |
| Limpopo, North West, Free State | Standard Rate | Average rates with steady material costs and lower labor costs, especially in rural or less populated areas. | |
| Northern Cape, Eastern Cape | -5% – Standard Rate | Lower labor rates in rural or low-cost-of-living areas, slightly reducing installation costs. | |
| Colorbond Type | Standard Colorbond (Standard Grade) | R100 – R150 per sq m | Most affordable option, available in standard colors, ideal for residential properties. |
| Colorbond Ultra | R150 – R200 per sq m | Designed for coastal areas; offers enhanced corrosion resistance. | |

| Roof Size | Small Roof (100 sq m) | Standard Material and Labor Cost | Small home roofs or extensions; usually lowest end of the cost range. |
| Medium Roof (200 sq m) | +10% – +15% on material and labor costs | Common size for residential properties, requiring more materials and labor. | |
| Large Roof (300+ sq m) | +20% – +30% on material and labor costs | Larger roofs for commercial or extensive residential properties. | |
| Roof Pitch | Low Pitch (below 10°) | Standard Rate | Easiest for installation with minimal labor adjustments. |
| Medium Pitch (10° – 25°) | +10% on labor costs | Moderate pitch requires more labor due to installation difficulty. | |
| Steep Pitch (above 25°) | +20% – +30% on labor costs | Increases labor costs significantly due to safety and access requirements. | |
| Installation Type | Basic Installation | R100 – R150 per sq m | Standard installation for low-pitch and simple roof designs. |
| Reinforced Installation | R150 – R200 per sq m | Required for steep-pitch or high-wind areas; includes extra bracing and support. | |
| Additional Services | Insulation Layer | +R40 – R60 per sq m | Adds insulation beneath the roof to improve energy efficiency and soundproofing. |
| Roof Removal and Disposal | +R30 – R50 per sq m | Necessary for replacing old roofing material, especially for full replacements. | |

Example Calculation
For a 200 sq m roof in Western Cape with:
- Colorbond Type: Colorbond Matt (R170 per sq m)
- Installation Type: Basic Installation (R100 per sq m)
- Additional Services: Insulation (R50 per sq m)
- Roof Pitch: Medium Pitch (+10% on labor)
Estimated Calculation:
- Material Cost: 200 sq m * R170 = R34,000
- Installation Cost: 200 sq m * R100 = R20,000
- Insulation: 200 sq m * R50 = R10,000
- Pitch Adjustment: R20,000 * 1.1 = R22,000
Total Estimated Cost: R66,000
