1. What is Rollex Soffit?

Rollex soffit is a vinyl siding component used to enclose the underside of roof overhangs. It provides ventilation while protecting the roof structure from weather and pests.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Roof\ Perimeter \) — Total linear footage around the roof edge (ft)
• \( Soffit\ Width \) — Width of the soffit area (ft)

Explanation: Multiplying the perimeter by width gives the total square footage of soffit material needed.

3. Importance of Accurate Calculation

Details: Proper calculation ensures you purchase the correct amount of material, minimizing waste and preventing project delays due to insufficient materials.

4. Using the Calculator

Tips: Measure the roof perimeter accurately, including all eaves. Typical soffit width ranges from 12-24 inches (convert to feet for calculation).

5. Frequently Asked Questions (FAQ)

Q1: How do I measure roof perimeter?
A: Measure the linear distance around all roof edges where soffit will be installed. Include all eaves and overhangs.

Q2: Should I add extra for waste?
A: It's recommended to add 10% to your total for cutting waste and mistakes, especially on complex roof lines.

Q3: What's the standard soffit width?
A: Most homes use 12-16 inch soffits, but this varies by design. Measure your actual overhang width.

Q4: Does this account for vented soffit?
A: The area calculation is the same for solid or vented soffit. Specify vented when ordering materials.

Q5: How does this differ for multi-story homes?
A: Calculate each level separately and sum the totals, as soffit widths may differ by floor.
