# How Big Is a Square in Roofing?

The total square footage of a roof is a measurement of the distance from the bottom of the tallest shingle to the bottom edge of the highest pitched roofing system. It’s the square footage divided by the total square footage to get the total area covered by a roof. In an average house, the total square footage of the roof is about three-tenths of an acre. If you were to measure the roof of your entire home, you would get a measurement of just under one hundred and twenty-eight thousand two hundred and forty-two square feet. That’s about one quarter of an acre at the very least.

How Big is a Square in Roofing – Using Roofing Shingles? It depends on the type of roofing system you have. If you have asphalt shingles, then the answer to the question how big is a square in roofing will be easy. You get the answer by taking the length of the asphalt shingles and multiplying that by the total number of shingles. This gives you the exact answer.

If you have a wood roof, then it becomes a little more complicated. You can figure out how big a square in roofing you’ll need by taking the length of the roof and dividing it by the number of shingles. In most cases, it’s best to leave the top few inches of shingles intact so that you have maximum protection against natural elements. The reason for that is that natural elements can cause roof leaks, which can be really expensive to repair. But in most cases, you’re better off replacing the entire old roof rather than the sections damaged by storms or fires.

As you look at how big a square in roof area is, you also have to consider the orientation of your home. If your house has an east-west orientation, you’ll want to leave about a third of the total square footage of your roof area used. If your home has a north-south orientation, you’ll want to leave one-half of the total square footage unshaved. And if you have a north-east or north-west orientation, you’ll want to shave about a quarter of the roof area.

Once you’ve figured out how big a square in roof area is, you can then determine the thickness of the materials that you’re going to use. If your roof is made from single plywood sheets, then you’re looking at a thickness of about two or three inches. If your roof is made from a composite product like asphalt shingles, then you’re looking at a thickness of about six or eight inches. The thickness of the underlayment will also be important because the thickness of the underlayment determines how well your new roof system will work and provide enough cushioning against storms and other types of damage.

If you’re dealing with a flat roof, then the total square footage of your roof is going to be about one hundred and forty-five square feet. If you’re dealing with a higher pitched roof like a gable roof, then the total square footage of your roof can be anywhere from one hundred to one hundred and eighty-five square feet. As you can see, calculating the exact size of a square in roofing is pretty difficult. It really depends on what you’re trying to accomplish, the structure of your roof, and what materials are used to build your roof. Fortunately, there are some simple formulas that can help you figure it out.
