Commercial Roof Replacement Cost Calculator

When it comes to commercial roof replacement, it’s crucial to have a clear estimate of the costs involved. Roof replacement is a significant investment for any business, and having a precise budget can help you plan accordingly. To assist you in this process, we have developed the Commercial Roof Replacement Cost Calculator.


The estimated cost for commercial roof replacement is calculated using the following formula:

Total Cost = (Total Square Footage × (Roofing Material Cost per Sq. Ft. + Labor Cost per Sq. Ft.)) + Other Costs

How to Use

Using our Commercial Roof Replacement Cost Calculator is straightforward:

  1. Enter the total square footage of the roof that needs replacement in the “Total Square Footage” field.
  2. Input the cost of roofing material per square foot in the “Roofing Material Cost per Sq. Ft.” field.
  3. Specify the labor cost per square foot in the “Labor Cost per Sq. Ft.” field.
  4. Optionally, you can add any other costs, such as permits or disposal fees, in the “Other Costs” field.
  5. Enter the estimated lifespan of the new roof in years in the “Estimated Lifespan (in years)” field.
  6. Click the “Calculate” button to get an estimate of the total cost.

The calculator will provide you with an estimated cost for your commercial roof replacement project.


Let’s say you have a commercial property with a total square footage of 5,000 sq. ft. The roofing material costs $2.50 per sq. ft., labor costs $1.50 per sq. ft., and you have no additional costs. If you expect the new roof to last for 20 years, the estimated cost would be:

Total Cost = (5,000 sq. ft. × ($2.50 + $1.50)) + $0 = $20,000
