Are you gearing up for a roofing project on your 2400 square foot house? If so, you’re probably wondering, “How many bundles of shingles do I need?” This is a crucial question to ensure you purchase the right amount of materials without overspending or coming up short. In this blog post, we’ll provide a straightforward answer and guide you through the process.

## Understanding the Basics

Before we dive into the calculation, let’s cover some basics:

• Shingles are typically sold in bundles, and each bundle covers a specific area. The most common type is the 3-tab asphalt shingle.
• Roofing measurements are often done in “squares,” where one square equals 100 square feet of roofing material. This simplifies calculations for roofing projects.

## Steps to Calculate Shingles

Calculating the number of shingles needed for your 2400 square foot roof is a simple process. Follow these steps:

Start by measuring the length and width of your roof. If your roof has multiple sections or slopes, measure each one separately and add the measurements together. Round up your measurements to the nearest foot for ease of calculation.

### 2. Calculate the Roof’s Area

Multiply the length by the width of each roof section to find its area in square feet. Then, sum up the areas of all sections to get the total square footage of your roof.

### 3. Convert to Squares

Since roofing materials are often sold in squares (100 square feet), divide your total roof square footage by 100. This will give you the number of squares required.

### 4. Check Shingle Coverage

Different shingle brands and types may have slightly varying coverage per bundle. Most 3-tab asphalt shingles cover approximately 33 square feet per bundle. To determine the number of bundles needed, divide the number of squares by the shingle’s coverage per bundle.

Example Calculation:

Suppose your 2400 square foot roof consists of two sections: Section A is 1200 square feet, and Section B is 1200 square feet.

• Total square footage: 1200 (Section A) + 1200 (Section B) = 2400 square feet.
• Convert to squares: 2400 square feet ÷ 100 = 24 squares.
• Shingle coverage per bundle: Approximately 33 square feet per bundle.
• Bundles needed: 24 squares ÷ 33 = approximately 73 bundles.

## Verdict

For your 2400 square foot roof, you’ll likely need around 73 bundles of 3-tab asphalt shingles to cover the entire area. It’s always a good idea to purchase a little extra for waste and potential future repairs.
