How big is a square in roofing

    The term “roofing square” is a commonly used term in the roofing industry. It is a unit of measurement for calculating the size of a roof where one roofing square is equal to 100 square feet.

    Why Roofing Square is measured, this way?

    In addition to being a larger unit of measurement, a square is used so that there’s a standardized measurement no matter the layout or shape of the roof. In other words, it doesn’t matter how you get to it, as long as it leads to 100 square feet. For example;

     

    • 10 ft x 10 ft = 100 square ft, which equals 1 roofing square.
    • 5 ft x 20 ft = 100 square ft, which equals 1 roofing square.

    All of these would require one square of material to cover.

    Before starting any roofing project, you’ll need to know exactly how much material you need. And that means knowing exactly how big your roof is. The most common roofing materials used include shingles, membrane roofing, and ceramic tile, all of which have different life spans.

    Shingle roofs typically have a life span of 15-30 years, while membrane roofs usually last 5-15 years. Although ceramic tile roofs are expensive, they can have a life span of over 100 years.

    How Many Shingles/Tiles are in roofing square?

    When purchasing shingles for your roof, they are usually sold by the “bundle”. Each bundle is a wrapped package of shingles with such a weight as to be lifted easily by a person. The most common is to have three bundles of shingles for a square of roof area. In other words, if you buy 3 bundles of shingles, this will cover one square which is 100 sq.ft of area.

    When it comes to roofing tiles, these vary in size. So there can be a huge difference in how many tiles will fill one square on your roof. Concrete tiles are usually around 90 tiles per square, while some clay tiles can range from 80 to 100. Some other types of tile may run 160 tiles per square or more.

    What is the cost per roofing square?

    The cost per square depends on the materials you choose to use for your roof. Including the cost of installation, most roof replacements will cost between $300 and $450 per square if you’re installing shingles. Tiles usually cost more. However, beyond juts the materials, there are a number of other factors that may affect cost. These may include:

     

    • Size and pitch of your roof
    • How difficult it is to access
    • If you need old material removed
    • A remaining warranty on the roof
