Step-by-Step Guide: How to Use the Asphalt Shingle Calculator

Using the Asphalt Shingle Calculator is straightforward. Follow these steps:

Step 1: Enter Roof Dimensions

• Input your roof length in feet.
• Input your roof width in feet.
• Make sure your measurements are accurate, as this directly impacts the calculation.

Step 2: Enter Shingle Coverage

• Input the coverage per bundle, which is usually listed on the shingle packaging (commonly 33 sq ft per bundle).

Step 3: Calculate Shingles Needed

• Click the Calculate button.
• The calculator will show a progress bar while performing the calculation.

Step 4: Review Results

• Total Roof Area (sq ft): The total square footage of your roof.
• Bundles Needed: How many bundles are required to cover the roof.
• Extra Bundle (10%): Recommended extra shingles to account for waste or cuts.

Step 5: Copy or Share Results

• Use the Copy Results button to save the data.
• Use the Share Results button to send your calculation via social media or email.

Practical Example

Imagine you have a roof that is 50 ft long and 30 ft wide, and your shingle coverage per bundle is 33 sq ft.

1. Multiply the length and width: 50 × 30 = 1,500 sq ft (total roof area).
2. Divide by coverage per bundle: 1,500 ÷ 33 ≈ 45.45, rounding up gives 46 bundles.
3. Add 10% extra for waste: 46 × 0.10 = 4.6, rounding up gives 5 extra bundles.

Result: You will need 46 bundles, plus 5 extra, for a total of 51 bundles.

This practical example shows how the tool simplifies planning, preventing both shortages and over-purchasing.
