This tool will help you estimate the number of shingles needed for your roof.
How to Use the Shingle Roof Calculator
Follow the steps below to calculate the total area and cost for shingling your roof.
- Enter the length of your roof in feet in the “Roof Length” field.
- Enter the width of your roof in feet in the “Roof Width” field.
- Enter the pitch of your roof in degrees in the “Roof Pitch” field. Common values range from 10 to 45 degrees.
- Enter the cost per square (100 sq ft) of the shingles you’re planning to use in the “Cost per Square” field.
- Enter the waste factor percentage in the “Waste Factor” field to account for materials that will be wasted during installation. Common values range from 5% to 15%.
- Click the “Calculate” button to get the total roofing area and cost.
How the Calculator Works
This calculator computes the total roofing area and cost based on the input parameters. It multiplies the roof length and width to get the base area. It then adjusts for the roof pitch by increasing the base area proportionally. Next, it adds the waste factor to this adjusted area to account for potential materials waste. Finally, it calculates the total cost based on the cost per square of roofing material.
Limitations
This calculator assumes a simple rectangular roof without any complex shapes or multiple pitches. Results may vary for more complex roof structures. Please consult with a roofing professional for more specific estimates.
Use Cases for This Calculator
Calculate Shingle Quantity
Enter your roof’s dimensions and choose the shingle type to calculate the exact quantity needed, ensuring you buy just enough for the job without overestimating.
Determine Total Cost
By inputting the price per bundle, you can quickly get an estimate of the total cost of shingles required for your project, helping you plan your budget effectively.
Compare Shingle Types
Compare different shingle types by entering their prices and calculating the total cost, enabling you to make an informed decision based on cost-effectiveness.
Estimate Installation Time
Calculate the estimated installation time for the shingles based on the roof’s size and complexity, allowing you to plan your project timeline efficiently.
Account for Waste Factor
Include a waste factor percentage when calculating shingle quantity to ensure you have enough materials, accounting for any potential mistakes during installation.
Calculate Pitch Factor
Factor in the roof’s pitch when estimating shingle quantity to adjust for additional materials needed due to steeper inclines, giving you a more accurate calculation.
Input Custom Shingle Dimensions
Enter custom shingle dimensions to calculate the exact quantity required for non-standard shingle sizes, providing precise measurements tailored to your needs.
