4. Colorbond Roofing Cost Calculator Guide
Calculate your Colorbond roofing costs with this simple step-by-step guide. While we recommend getting professional quotes, this helps you estimate your budget.
Step-by-Step Calculation Method
Step 1: Measure Your Roof Area
For a simple rectangular roof:
Roof Area (m²) = Length × Width × Pitch Factor
Pitch factors: Flat = 1.0, 15° = 1.04, 22.5° = 1.08, 30° = 1.15, 45° = 1.41
Example: 12m × 8m house with 22.5° pitch = 12 × 8 × 1.08 = 103.68m²
Step 2: Select Material Cost Per M²
Choose based on profile and colour:
- Budget (Corrugated, standard colour): $30/m²
- Mid-range (Trimdek, popular colour): $40/m²
- Premium (Kliplok, designer colour): $50/m²
Step 3: Add Installation Labour
Installation costs vary by complexity:
- Simple roof: $40/m²
- Standard complexity: $60/m²
- Complex/steep roof: $80/m²
Step 4: Add Additional Costs
- Flashings and trims: Perimeter (m) × $25
- Sarking/insulation: Roof area × $10
- Old roof removal: Roof area × $25
- Permits and fees: $1,000-2,000
📊 Example Calculation: 150m² Home
1. Roof area: 150m²
2. Material (Trimdek): 150 × $40 = $6,000
3. Labour (standard): 150 × $60 = $9,000
4. Flashings (50m): 50 × $25 = $1,250
5. Sarking: 150 × $10 = $1,500
6. Removal: 150 × $25 = $3,750
7. Permits: $1,500
TOTAL ESTIMATE: $23,000
(Range: $21,000-25,000 depending on specific requirements)
⚠️ Important: This is an estimate only. Get at least 3 professional quotes for accurate pricing. Unexpected costs like structural repairs, asbestos removal, or complex drainage can significantly affect the final price.
