How to Use the Roof Replacement Calculator:

This calculator helps you estimate the total cost of replacing a roof. Here’s how you can use it:

  • Length of Roof: Enter the length of the roof in feet.
  • Width of Roof: Enter the width of the roof in feet.
  • Pitch of the Roof: Select the pitch of the roof. The pitch determines the slope of the roof.
  • Cost per Square Foot: Enter the cost of roofing materials per square foot.
  • Waste Factor: This is the percentage of material that will be wasted during the roofing process. The default value is 10%.

Click the “Calculate” button to get the estimated total cost of replacing the roof.

Explanation of Calculation:

The calculation is performed as follows:

  1. The area of the roof is calculated by multiplying the length and width and adjusting for the pitch.
  2. The waste factor is added to the area to account for extra materials needed.
  3. The total cost is then calculated by multiplying the adjusted area by the cost per square foot.

Limitations:

This calculator provides an estimate and may not account for additional costs such as labor, permits, or removal of the old roof. For an accurate quote, please consult a professional roofing contractor.
