1. What is Cost Per Square in Roofing?

In roofing, a "square" is a unit of measurement equal to 100 square feet. The cost per square helps contractors and homeowners compare roofing material prices and estimate total project costs more accurately.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• Total Cost — Complete roofing project cost in South African Rand (ZAR)
• Area — Total roof area in square feet

Explanation: Dividing the total cost by the number of squares (area/100) gives the cost per 100 square feet, which is the standard roofing measurement unit.

3. Importance of Cost Per Square Calculation

Details: Calculating cost per square allows for accurate budgeting, comparison between different roofing materials and contractors, and helps prevent overpaying for roofing projects.

4. Using the Calculator

Tips: Enter the total project cost in ZAR and the roof area in square feet. Ensure both values are positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate cost per square instead of cost per sq ft?
A: Roofing materials are typically sold and priced by the square (100 sq ft), making cost per square the industry standard for comparison.

Q2: What's the average cost per square in South Africa?
A: Costs vary widely (ZAR 800-3000 per square) depending on materials (shingles, tiles, metal) and labor costs in different regions.

Q3: Should I include removal of old roofing in the total cost?
A: Yes, for accurate cost per square calculation, include all project costs - materials, labor, removal, and disposal.

Q4: How do I measure my roof area accurately?
A: For complex roofs, consult a professional. For simple roofs: length × width × slope factor (typically 1.1-1.3 for pitched roofs).

Q5: Does this calculator work for other countries?
A: Yes, though currency and measurement units may need adjustment. The formula remains the same regardless of location.
