Planning a roofing project? One of the most common questions homeowners ask is: how many bundles in a Roofing Square Whether you’re tackling a DIY roof replacement or getting quotes from contractors, understanding roofing measurements like “squares” and “bundles” is essential to budgeting and getting the job done right.
This guide walks you through everything you need to know about calculating your roof size, estimating how do I measure a roof for shingles? you’ll need, and making sure your shingle roofing in Meriden, CT goes off without a hitch.
How Many Bundles in a Roofing Square?
What Is a Roofing Square?
In roofing terms, a “square” refers to a unit that covers 100 square feet of roof area. So, if your roof is 2,000 square feet, that means you’ll need 20 squares of shingles.
Bundles per Square
Typically, it takes three bundles of asphalt shingles to cover one roofing square. However, this number can vary slightly depending on the type, brand, and style of the shingles you choose.
Here’s a simple breakdown:
| Shingle Type | Bundles per Square |
|---|---|
| Standard 3-tab asphalt | 3 bundles |
| Architectural shingles | 3–4 bundles |
| Premium or designer shingles | 4+ bundles |
🎯 Quick Formula:
Total Roof Area (in sq. ft.) ÷ 100 = Total Squares
Total Squares × 3 = Total Bundles (approx.)
For example, if your roof is 1,800 square feet:
1,800 ÷ 100 = 18 squares
18 × 3 = 54 bundles
🚨 Important Factors to Consider:
- Roof Pitch: Steeper roofs require more shingles due to the angled surface.
- Wastage: Always add 10–15% extra for cutting, starter strips, and overlaps.
- Valleys & Dormers: These require extra material for proper sealing and layering.
Step-by-Step: How Do I Measure a Roof for Shingles?
There are two ways to calculate the size of your roof: the manual (on-roof) method and the digital method (using aerial tools or apps).
1. Measure the Roof Manually
If you’re comfortable using a ladder and walking on your roof, here’s how to do it:
- Divide your roof into rectangular sections.
- Measure the length and width of each section in feet.
- Multiply the length by the width to get the square footage of each section.
- Add up all the sections for the total roof size in square feet.
- Divide the total square footage by 100 to determine how many roofing squares you need.
Example:
If your roof has three sections that measure:
- 20 ft x 10 ft = 200 sq ft
- 15 ft x 10 ft = 150 sq ft
- 25 ft x 10 ft = 250 sq ft
Total = 600 sq ft ÷ 100 = 6 roofing squares
2. Use an Online Shingle Calculator
If you’re not comfortable climbing your roof, you can use online tools like RoofCalc.org or GAF’s shingle calculator. These allow you to input your home’s dimensions or even use satellite imagery to measure accurately.
These calculators also account for roof pitch, which can significantly affect your measurements. A steeper roof means a larger surface area.
How Many Bundles of Shingles per Square?
Now that you know how many squares of shingles your roof requires, let’s talk bundles. Typically, it takes:
- 3 bundles of standard 3-tab asphalt shingles = 1 square
- 4-5 bundles for architectural or designer shingles = 1 square (depending on brand and thickness)
So, if your roof is 20 squares:
- You’ll need 60 bundles of standard 3-tab shingles.
- Or potentially 80–100 bundles of thicker shingles.
Always add 10% extra for waste, overhangs, and cutting.

Common Mistakes When Measuring for Shingles
Avoid these costly errors when calculating roofing materials:
- Forgetting to Add Waste Factor: Always add 10%–15% extra for cutting and overlap.
