What Is a Square of Roofing Shingles?

what is a square of roofing shingles

When you buy shingles for your roof, you are most likely going to buy them in bundles of several shingles. Some manufacturers pack three or four bundles per square, while others sell only one or two bundles. Regardless of the manufacturer, there are a few things you need to keep in mind when purchasing roofing shingles. These measurements are important to keep in mind, because a square of shingles equals approximately the size of a football field.

First, determine the square footage of your roof. Typically, a roof is approximately 800 square feet. Then, divide that number by 100 to determine the number of roofing squares you’ll need. For example, a roof with a standard pitch of eight percent would require 18 squares of shingles. Also, take into account how steep your roof is. The higher your roof pitch, the more roofing squares you need.

Another important consideration when purchasing shingles is the price. The price for roofing squares varies by material and pitch. To get an accurate estimate, measure the square footage and pitch of your roof to determine how many shingles you’ll need. If you don’t have an accurate measurement of your roof, use the Roof Shingle Estimator. You’ll need to calculate the number of squares to buy in order to obtain an accurate price quote.

A square of roofing shingles covers approximately 1/3 of a square roof. For instance, a roof with twenty squares would require sixty bundles. If you’re buying three-tab shingles, you’ll need three bundles per square. Similarly, if you’re purchasing three-tab shingles, you’ll need three bundles per square. To figure out how many roofing bundles you need, multiply the square footage by three.

The most accurate way to calculate shingle quantity is to measure the roof’s planes separately. In simple cases, you can multiply the length of the building by the width of the roof. For more complex roofs, such as those that include a rake edge, you can measure from ground level and calculate the amount of shingles you’ll need. Aside from that, the rake-edge overhangs on steep roofs are also important to consider when calculating square footage.

Besides the slope, another consideration when calculating the amount of roofing material is the roof’s pitch. If your roof is steeper than usual, you’ll need to purchase more squares of roofing shingles. To calculate the slope, multiply the height of your roof by twelve inches, for example. For the same effect, you should multiply the squares by four to determine the shingle coverage needed for a roof that has a 4:12 slope. If you’re unsure, you can find online calculators that will help you calculate the slope. Remember to include a 10%-15% waste factor when you calculate the shingle coverage.

Roofing shingles are sold in squares or bundles, and a square covers 100 square feet. Depending on the manufacturer, a bundle can range from $30 to over $1,800 per square. A bundle of roofing shingles covers approximately 33 square feet, while a square of slate can cost up to $1,800. While each bundle has a different square size, the overall weight of roofing shingles is comparable to one another.
