Explanation: This calculation standardizes roofing costs to a per-100-square-foot basis, making it easier to compare projects of different sizes and estimate costs for new projects.
Details: Calculating cost per square is essential for accurate budgeting, comparing contractor quotes, estimating material needs, and understanding the value of different roofing materials and installation methods.
Tips: Enter the total cost of your roofing project and the total area in square feet. Ensure both values are positive numbers for accurate calculation.
Q1: What is included in "total roofing cost"?
A: Total roofing cost typically includes materials, labor, removal of old roofing, underlayment, flashing, vents, and any additional components specific to your project.
Q2: How do I measure my roof area accurately?
A: For simple roofs, multiply length by width. For complex roofs, break it into sections or consult a professional. Many contractors offer free measurements and estimates.

A: Costs vary widely by material ($150-600+ per square) and location. Asphalt shingles are typically $150-400 per square, while metal, tile, or slate can be $400-1000+ per square.
Q4: Does cost per square include tear-off and disposal?

Q5: How does roof pitch affect cost per square?
A: Steeper roofs typically cost more per square due to increased labor, safety equipment, and sometimes specialized installation techniques required.
