1. What is a Cost Asphalt Shingles Roof Installed Calculator?

Definition: This calculator estimates the total installed cost of an asphalt shingle roof based on the roof size in squares, material cost per square, and labor costs.

Purpose: It helps homeowners and contractors budget for roofing projects by calculating both material and installation costs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( C \) — Total installed cost ($)
• \( Q \) — Roof quantity (squares)
• \( P_{square} \) — Price per square ($/square)
• \( C_{labor} \) — Labor cost ($)

Explanation: The roof size is multiplied by material cost per square, then labor costs are added to get the total installed price.

3. Importance of Roof Cost Calculation

Details: Accurate cost estimation helps with budgeting, comparing contractor quotes, and planning financing for roofing projects.

4. Using the Calculator

Tips: Enter the roof size in squares (1 square = 100 sq ft), material cost per square (default $100), and any additional labor costs. All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a "square" in roofing terms?
A: One square equals 100 square feet of roof area, the standard measurement unit for roofing materials.

Q2: What's a typical price per square for asphalt shingles?
A: Prices range from $80-$150 per square for materials, varying by shingle quality and region.

Q3: Should labor be included per square or as a total?
A: You can enter labor either way - either as a total project cost or calculate it separately per square and enter the total.

Q4: How do I find my roof's square footage?
A: Measure length × width of each roof plane, add them together, then divide by 100 to get squares.

Q5: Does this include removal of old roofing?
A: No, this calculates new installation only. Add tear-off costs separately if needed.
