By inputting the roof's dimensions (length and width), material cost per square unit, labor cost per unit foot, and any additional costs (e.g., permits or removal fees), this calculator provides an accurate breakdown of the total cost.
Replacing a roof can be a significant investment, and accurately estimating the costs is crucial for proper planning. Our Roof Replacement Cost Calculator simplifies this process by providing a clear breakdown of the total costs based on dimensions, material cost, and labor cost.
How to calculate Roof Replacement Cost
Step 1:Calculate Total Roof Area
To calculate the total roof area, you multiply the roof’s length and width:
Formula for Total Roof Area
Total Roof Area=Length×Width
Step 2: Calculate Material Cost
The cost of roofing materials is calculated by multiplying the total roof area by the cost per square unit of material:
Formula for Material Cost
Material Cost=Total Roof Area×Material Cost Per Unit
Step 3: Calculate Labor Cost
Labor costs are calculated by multiplying the total roof area by the labor cost per unit foot:
Formula for Labor Cost
Labor Cost=Total Roof Area×Labor Cost Per Unit
Step 4: Calculate Total Cost
The total cost of replacing the roof is the sum of the material cost, labor cost, and additional costs (e.g., permits, removal fees, etc.):
Formula for Total Cost
Total Cost=Material Cost+Labor Cost+Additional Costs
Example Calculation
Let’s walk through a complete example step-by-step.
Inputs:
- Roof Length: 40 feet
- Roof Width: 25 feet
- Material Cost per Square Unit: $4 per square foot
- Labor Cost per Unit Foot: $2.5 per square foot
- Additional Costs: $500
Step 1: Calculate Total Roof Area
Total Roof Area=40×25
Total Roof Area=1000 square feet
Step 2: Calculate Material Cost
Material Cost=1000×4
Material Cost=4000
Step 3: Calculate Labor Cost
Labor Cost=1000×2.5
Labor Cost=$2500
Step 4: Calculate Total Cost
Total Cost=4000+2500+500
Total Cost=$7000
