I. Introduction
When it comes to roofing projects, there are many factors to consider, including the number of shingles needed per bundle. Shingle bundles are the packaged units of asphalt shingles sold by manufacturers and suppliers. Knowing how many shingles in a bundle is crucial for accurate cost estimation, labor planning, and material ordering. This article aims to provide an in-depth exploration of shingle bundles, including the different bundle sizes, the average number of shingles per bundle, and tips and strategies for maximizing their value.
A. Definition of shingle bundles
A shingle bundle is a package of asphalt shingles that contains a specific number of shingles. The number of shingles per bundle can vary depending on the manufacturer and the type of shingles in the bundle.
B. Importance of knowing how many shingles in a bundle
Knowing how many shingles come in a bundle is essential because it determines the amount of material needed for a roofing project. If you order too few bundles, you may end up running out of shingles before the project is complete. On the other hand, if you order too many, you’ll be left with unnecessary surplus that will drive up the project cost.
C. Purpose of the article
The purpose of this article is to provide comprehensive information and tips on shingle bundles—from the basics of calculating the coverage area to maximizing the value of each bundle. By the end of this article, you’ll have a better understanding of shingle bundles and how to make the most of them for your roofing project.
II. Demystifying Shingle Bundles: Determining Quantity and Coverage
Before we delve into the specifics of shingle bundles, it’s important to have a basic understanding of square footage and roof pitch.
A. Understanding square footage and pitch
Roofing professionals use square footage as the primary measurement of a roof’s coverage area. To calculate the square footage of your roof, measure the length and width of each section and multiply them. Most roofing estimates require adding 10% extra for waste or there may be patterns that will result in more waste material.
Roof pitch refers to the angle or slope of the roof. It helps determine how many shingles are required per square foot of coverage. A steeper roof pitch requires more shingles to cover each square foot.
B. Calculating the number of shingles needed
To calculate the number of shingles needed for a roofing project, you need to know the square footage of the roof and the slope or pitch of the roof. Manufacturers provide instructions on the number of shingles needed to cover one square, which is an area of 100 square feet. The number of shingles needed per square will vary depending on the type of shingles, such as 3-tab or architectural.
For instance, a project with a 1,500 square foot roof with a 6:12 roof pitch requires 23.5 squares of shingles. If one bundle of shingles covers 33.33 square feet and there are 21 shingles in each bundle, you would need 540 shingles (23.5 x 3) to complete the project.
C. Choosing the right bundle size
Manufacturers offer different bundle sizes depending on the number of shingles in each bundle. The most common bundle size is three bundles, which covers approximately 100 square feet of roof surface. Other bundle sizes may be available for specific types or brands of shingles, such as tamko shingles having 4 bundles covering 100 sq ft of roof surface. The bundle size you choose should be based on the required coverage area, the shingle type, and the slope of the roof.
III. Shingle Bundles 101: How Many Shingles Come in a Bundle and What It Means for Your Roofing Project
The average number of shingles per bundle varies depending on the shingle type and the manufacturer.
A. Types of shingle bundles
There are two types of shingle bundles: three-tab shingles and architectural shingles. Three-tab shingles are the most common type, and they come in bundles containing around 21 shingles. Architectural shingles are thicker and more durable, and they typically come in bundles containing between 16 and 18 shingles.
B. Average number of shingles per bundle
On average, a bundle of three-tab shingles contains 21 shingles and covers approximately 100 square feet of surface area. An architectural bundle generally contains between 16 and 18 shingles and covers approximately the same area. Here is an example of how to calculate the number of required shingles for a 1,500 square foot roof:
- 1,500 square feet divided by 100 square feet per square is 15 squares.
- Each square requires three bundles of three-tab shingles or four bundles of architectural shingles.
- To cover a 1,500 square foot roof with three-tab shingles, you will need 45 bundles.
- To cover the same roof with architectural shingles, you’ll need a little more than 60 bundles.
C. Factors that affect the number of shingles per bundle
The number of shingles per bundle can vary depending on the manufacturer and the type of shingles. Other factors that can affect the number of shingles per bundle include shingle thickness, the shape of the shingles, and waste allowance.
IV. Understanding Shingle Bundles: Calculation Methods and Pro Tips for Accurate Estimates
To avoid over-ordering or under-ordering shingle bundles, you need to have an accurate estimate of the material you need for your roofing project.
A. Common calculation methods
The most common method of calculating the required number of shingles for a roofing project is the “square” calculation. A square represents 100 square feet of roof coverage. You can use the following formula to calculate the number of squares:
- Length x width of the roof section = square feet of the roof section.
- Add up the square footage of all sections.
- Round up to the nearest 100 to get the total square footage.
- Divide the total square footage by 100 to get the total number of squares.
- Multiply the total number of squares by the number of shingles per square to get the total number of shingles required.
Another method is to use an online shingle calculator or a material estimation tool provided by the supplier or manufacturer. These tools factor in the shingle type, roof pitch, and waste allowance to provide an accurate estimate.
B. Tools and resources for accurate estimates
Many reputable suppliers and manufacturers provide online tools to help you determine the quantity of shingles needed for your roofing project accurately. Shingle manufacturers also provide installation guides with step-by-step instructions and illustrations that can help you estimate the number of required shingles.
C. Pro tips for minimizing waste and maximizing coverage
To minimize waste, try to purchase the exact amount of shingles needed for the roofing project. Buy 5% more, if you can afford it, to account for possible miscalculation or waste due to cutting. Installing shingles on roofs with multiple planes or hips and ridges can create more waste due to the need to cut or trim shingles. Try to install shingles in warmer months as they are more pliable, reducing the risk of damage and improving fit.
V. Counting Your Shingle Bundles: A Step-by-Step Guide to Find the Right Amount for Your Roof
To accurately calculate the number of shingle bundles you need, follow these steps:
A. Measuring your roof
Measure each section of your roof and record the length and the width. Multiply the length and the width of each section to get the square footage. Add up all the square footage measurements to get the total square footage of your roof. Be sure to factor in ridges, hips, and valleys, and add about 10% for waste or possible changes in the roof’s coverage area.
B. Calculating the number of shingle bundles needed
Divide the total square footage by 100 to determine the number of squares you need to cover. Multiply the number of squares by the number of shingles per bundle you are using. Round up to the nearest full bundle, and order that amount or add a few extra bundles to allow for waste and any cutting needed.
C. Adjusting for waste and leftovers
Account for extra wastage when installing shingles around roof penetrations such as chimneys, and skylights. Additionally, Look to maximize leftover shingles by repurposing them for smaller projects or repairs such as doghouses, sheds or other roofing projects. Be sure to store any leftover shingles in a dry, clean area.
