Enter the total roof area, cost of roofing material per square foot, labor cost, and waste removal and disposal cost into the calculator to determine the roof replacement cost.

Roof Replacement Cost Formula

The following formula is used to calculate the roof replacement cost. 

RC = (A * M) + L + W

Variables:

  • RC is the total roof replacement cost ($)
  • A is the total roof area (square feet)
  • M is the cost of roofing material per square foot ($)
  • L is the labor cost ($)
  • W is the waste removal and disposal cost ($)

To calculate the roof replacement cost, multiply the total roof area by the cost of roofing material per square foot. Add the labor cost and the waste removal and disposal cost to the result.

What is a Roof Replacement Cost?

A roof replacement cost refers to the total amount of money a homeowner spends to completely remove and replace their existing roof with a new one. This cost typically includes the price of new roofing materials, labor charges, disposal of old materials, and any necessary permits or inspections. The exact cost can vary widely depending on factors such as the size and pitch of the roof, the type of materials used, the region where the home is located, and the roofing contractor's rates.

How to Calculate Roof Replacement Cost?

The following steps outline how to calculate the Roof Replacement Cost.

  1. First, determine the total roof area (A) in square feet.
  2. Next, determine the cost of roofing material per square foot (M) in dollars.
  3. Next, determine the labor cost (L) in dollars.
  4. Next, determine the waste removal and disposal cost (W) in dollars.
  5. Next, gather the formula from above = RC = (A * M) + L + W.
  6. Finally, calculate the Roof Replacement Cost.
  7. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total roof area (A) = 1000 square feet

cost of roofing material per square foot (M) = $5

labor cost (L) = $2000

waste removal and disposal cost (W) = $500
