Frequently Asked Questions
The main factors are roof area, material cost per square foot, labor cost per square foot, and waste percentage. Our calculator combines these to give an estimate.
This calculator provides a rough estimate. Actual costs may vary based on roof complexity, location, and specific materials chosen. Consult a professional for precise quotes.
Typical waste is around 10-15% for simple roofs, but can be higher for complex designs. Our default is 10%, but you can adjust it.
