1. What is Roofing Cost Per Square?

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

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Cost per Square} = \frac{\text{Total Cost}}{\left(\frac{\text{Area}}{100}\right)} \]

Where:

Total Cost — Complete project cost in USD
Area — Total roof area in square feet
100 — Conversion factor (1 square = 100 sq ft)

Explanation: The equation converts total roof area into roofing squares, then divides the total cost by the number of squares.

3. Importance of Cost Per Square Calculation

Details: Calculating cost per square allows for accurate material comparisons, budget planning, and contractor price evaluations for roofing projects.

4. Using the Calculator

Tips: Enter total project cost in USD and roof area in square feet. All values must be valid (cost > 0, area > 0).

5. Frequently Asked Questions (FAQ)

Q1: What's included in total cost?
A: Include all material and labor costs for accurate per-square calculations.

Q2: How do I measure roof area?
A: Measure length and width of each roof plane, multiply to get area, then sum all planes.

Q3: What's a typical cost per square?
A: Asphalt shingles typically range $100-$400 per square, depending on quality and location.

Q4: Does this include underlayment?
A: Only if included in your total cost. For material-only calculations, exclude labor.

Q5: How does roof pitch affect cost?
A: Steeper roofs increase labor costs, which will be reflected in higher per-square costs.
