1. What is a Roof Temperature Calculator by Square Feet?

Definition: This calculator estimates the roof temperature based on base temperature, adjustment factor, and roof area.

Purpose: It helps construction professionals and homeowners understand how roof size affects surface temperature.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ T = T_{base} + \frac{k}{A} \]

Where:

\( T \) — Roof temperature (°C)
\( T_{base} \) — Base temperature (°C)
\( k \) — Adjustment factor (°C·ft²)
\( A \) — Roof area (ft²)

Explanation: The base temperature is adjusted by a factor that accounts for how roof area affects heat accumulation.

3. Importance of Roof Temperature Calculation

Details: Proper roof temperature estimation helps with material selection, energy efficiency planning, and understanding heat island effects.

4. Using the Calculator

Tips: Enter the base temperature in °C, adjustment factor (default 500 °C·ft²), and roof area in square feet. Area must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the base temperature?
A: This is the ambient air temperature before roof heating effects are considered.

Q2: What's a typical adjustment factor?
A: The default 500 °C·ft² works for many roofs, but this can vary based on material color, insulation, and climate.

Q3: When would I change the adjustment factor?
A: Increase for dark-colored roofs (up to 700) or decrease for light-colored/reflective roofs (down to 300).

Q4: How do I find my roof area?
A: Multiply length by width for each rectangular section, or use our Roof Area Calculator tool.

Q5: Does this account for shading or insulation?
A: No, consider reducing the adjustment factor if your roof has significant shading or extra insulation.
