How to Use the Asphalt Shingle Calculator

Using our calculator is straightforward. Here’s how to get the results you need:

1. Enter the Length and Width of the area you need to cover. You can adjust the units to feet, inches, or other measurements depending on your needs.
2. Select the Roof Pitch from the dropdown list, which will affect the total surface area that needs to be covered. The roof pitch determines the steepness of your roof, and the higher the pitch, the more material you’ll require.
3. Click “Calculate” to get the results. The calculator will provide the total "squares" of shingles you need to cover the area, as well as the number of rolls of felt and nails required for your project.

The results will include:

• Total "Squares" to Cover: This is the area of the roof in squares, a standard roofing unit where one square equals 100 square feet.
• Bundles of 3-Tab Shingles: The number of bundles required for your roofing project.
• Rolls of Felt: The number of rolls of roofing felt you'll need to lay under the shingles.
• Nails: The number of nails you'll need for the installation.

Example Calculation

Let’s say you're working on a small roof:

• Length: 2 feet
• Width: 4 feet
• Roof Pitch: 3/12

After inputting this information into the calculator, you’ll receive:

• Total "Squares" to Cover: 0.08 squares
• 3-Tab Shingles Bundles: 0.25 bundles
• Rolls of Felt: 0.02 rolls
• Nails: 27 nails

These estimates help you plan your project efficiently, ensuring you don’t over-purchase or run out of materials mid-job.

Factors to Consider When Calculating Shingle Requirements

While the calculator gives you a good starting point, there are some additional factors to keep in mind:

1. Roof Shape and Features: Complex roof shapes (like hips, valleys, or dormers) can increase the surface area and require more materials.
2. Waste Factor: It’s always wise to add 10% to your total estimate to account for mistakes, cuts, or wastage during installation.
3. Type of Shingle: Different types of asphalt shingles may have different coverage per bundle, so it’s important to check the manufacturer’s specifications.

Why Accurate Estimation Matters

Using an accurate calculator like this one can save you both time and money. It ensures you order just the right amount of materials, reducing the risk of over-purchasing and the costs associated with returns or additional deliveries. With the right materials on hand, you can complete your roofing project efficiently and with a professional finish.
