How Big is a Square in Roofing?

The question “How big is a square in roofing?” is a common one among home owners. One of the main reasons why this type of question arises is because of the many different types of shingles that are available for installation. A homeowner may initially purchase one type of shingle and have it installed on their roof. However, if they want to install another type of shingle they will want to know the size of the shingle needed in order to cover the entire roof.

Roofing professionals commonly measure the total square footage of the roof area in order to determine what the proper roofing materials will be. This is usually determined by the type of roof being installed. There are a couple of standard measurements that are used in residential as well as commercial applications. These measurements are the length and width of the roof area as well as the diagonal measurement between the length of the roof and the length of the ridge span. The average size of a square in roofing is determined by these two measurements.

There are several different factors that can change the size of a square in roofing. For example, the square footage of the roof area, including any gable roofs that surround the house, can impact the size of a square. In other words, if there are multiple stories in a house and all of the rooms are located on the same level, then the square footage of the roof area will increase significantly. Another factor that can add to the size of a square is the slope of the roof area.

The amount of new roofing added onto a house will also affect the answer to “How big is a square in roofing?” When adding new roofing to a home or business, the old shingles are removed and the newer, heavier vinyl roofing is installed. This process creates a slight difference in the appearance of the square in roofing. For this reason, the square should not be confused with “length x width” when comparing the two measurements.

A final factor to consider is the type of underlayment used in the roof. Different types of shingles will have different amounts of weight capacity. For example, asphalt shingles are the lightest of the types of shingles available and they do not need to support the weight of heavier shingles like tar and slate shingles do. Therefore, the thickness of the asphalt roofing underlayment will directly impact the question of “How big is a square in roofing?”

It is easy to see how the question of “How big is a square in roofing?” varies depending on the situation. For example, if there are multiple panels of shingles on a roof, then the total square footage of the installation will increase dramatically. If the roof is a single sheet, then the entire square footage measurement will remain the same. However, in either case, the materials and underlayment will play a large part in determining the final size of the installation.
