How Many Shingles Do You Need for a 1,884 Sq Ft Roof?
You will usually need between 63 and 70 bundles of shingles to finish the job if your roof is 1,884 square feet. The difference of the shingles depends on the shape of your roof and how much extra material you plan for making the roof. Roofers use waste factors to make up for losses from cutting, valleys, and starter courses.
The number 1,884 sq ft is the total area of your roof, not the number of shingles you need to buy. People sell roofing materials in “squares,” not square feet. One square of roofing is 100 square feet. So, changing the size of the roof to squares will help you figure out exactly how much material you need.
In Arlington, Texas, it’s important to choose the right materials because roofs have to deal with hot summers, strong winds, and hail. Most homeowners in the area choose impact-resistant shingles (Class 4) to protect their homes from storms in North Texas. Your roof will last for years and meet local building codes if you use the right amount of high-quality materials.
2. The “Cheat Sheet” Calculation
Below I am giving a table that provides you a quick overview to estimate your shingle needs for a 1,884 sq ft roof. Roof pitch and complexity determine how much extra material you’ll need to account for waste.
| Complexity level | Waste factor | Roofing squares (rounded) | Total bundle count |
| Simple gable | 10% | 21 squares | 63 bundles |
| Moderate (hips & valleys) | 15% | 22 squares | 66 bundles |
| Complex (steep, many cuts) | 20% | 23 squares | 69–70 bundles |
These totals assume 3 bundles = 1 square for standard asphalt shingles. Many common products follow this rule. The shingle wrapper lists the exact bundle coverage for that product.
3. Understanding the Math: How to Calculate Your Order
What is a roofing square?
A roofing square equals 100 sq ft of roof surface area. Roofers use this measurement because it simplifies estimating materials for any roof size.
To calculate total squares:
Squares = Roof area ÷ 100
For a 1,884 sq ft roof:
Squares = 1,884 ÷ 100 = 18.84 squares
You do not order 18.84 squares. You add waste and round up.
Bundle coverage and bundle count
A bundle is a packaged group of shingles. Many standard asphalt shingles cover about 33.3 sq ft per bundle which equals about three bundles per square.
Use this simple rule for standard shingles:
Bundles = Squares × 3
4. Estimating Waste Factor
When you are installing the shingles then you need extra materials because some shingles get cut and wasted around the roof edges, valleys, vents, ridge caps. This consideration is called the waste factor. Here you also consider the waste factors which are due to the extra Then add your waste factor and round up to a whole bundle.
Most roofs use 10% to 15% waste as a baseline. But if the roofs need more hips, valleys, or dormers then its waste will go upto 20% or more.
Example with a 10% waste factor:
- Start with squares: 18.84
- Add waste: 18.84 × 1.10 = 20.724 squares
- Round up: 21 squares
- Convert to bundles: 21 × 3 = 63 bundles
That range produces 63 to 69 bundles for standard shingles. Many crews add one more bundle for margin on a complex roof. That choice brings the count to 70 bundles.
5. Arlington, Texas Specifics: Local Codes and Weather
Wind resistance matters in Arlington
Arlington follows the IRC/IBC rules with changes made by Tarrant County. Arlington is in an area that gets strong storms and windy weather. The wind can tear off the edges of the roof and the first row of shingles. According to ASCE 7 standards, roofs need Class A fire-rated shingles and to be able to withstand winds of 110 to 130 mph. Starter strips and properly nailed shingles prevent shingles from being blown off at these edges.
The wind speed specified for the local design influences the choice of your asphalt shingles. In the shingle packaging, you will see a wind rating, so you can choose the right one for the job.
Hail resistance matters in North Texas
Therefore as we know that the Arlington gets a lot of hail. A lot of homeowners choose Class 4 impact-resistant shingles because they work better in hail. In roofing, Class 4 is the UL 2218 impact test standard.
Texas also has a list of roof-covering products that can get insurance credits if they meet standards for being resistant to impact. This is an important detail to keep in mind when you compare shingle prices.
Therefore if you are looking for the re-roofing then you must check for permits before doing it. For every 150 square feet of space, you need 1 square foot of attic ventilation. Use starter strips and ice-water shields at the eaves.
Permits and inspections in Arlington
So, if you are looking for the re-roofing then you must need a permit for it. And you can also apply online through the city’s portal, and an inspection is required to finish and close the permit.
