One of the most important terms you should be familiar with if you are about to start your roof replacement process is “roofing square.”

This article will find out all you need to know about what a roofing square is and how to calculate roofing squares.

A roofing square(s) is a measurement unit used to calculate the size of a roof, and it is equivalent to 100 square feet. This unit makes it easier to calculate roofing square feet.Â

The number of roofing squares in 1200 square feet is 12. One roofing square equals 100 square feet. Converting square feet to roofing squares is an easy thing to do. For a roof of 1200 square feet, you will have 12 squares. The value is obtained by dividing the square feet by 100 (1200/100 =12).

## How Many Roofing Squares In 1200 Squares?

As I mentioned earlier, a roofing square is a unit of measurement for determining the size of a roof, and it is equivalent to 100 square feet.

This large unit helps calculate the number of materials you will need for your roof.

It is a unit used in expressing 100 square feet. This unit simplifies the grouping of roofing materials like tiles, shingles, etc.

Only a few producers let you do free roofing square calculators online. You can let a professional assess your roof or measure it yourself.

If you want to measure the number of roofing squares your roof has, measure the total square footage of the roof and use the amount to determine the number of roofing squares it has.

Ensure that you have all the necessary equipment to climb your roof safely. You will need a measuring tape, a pen and notebook (to do your calculations), and a ladder. You may read our post if you don’t know how to climb up the roof.

Be extremely careful while climbing the ladder to avoid slipping off. Measure each roof planeâ€™s length and width. There may be more than two planes on the roof.

Some features that may cause your roof to have more than two planes are dormer windows, protruding garage, skylights, covered porches, and others. First, calculate each planeâ€™s area.

To get the total square footage, sum up the total of all the areas together. After getting the full square of the roof, convert it to roofing squares by dividing the number by 100.

You will have the pitch of the roof in mind to get the correct measurements.

There are 12 roofing squares in 1200 square feet. The surface of roofs is basically measured in squares. One square is equal to 100 square feet of the roof.

To calculate the number of squares of the roof, divide the total square feet by 100.

## How To Calculate Roofing Squares?

The number of roofing squares affects the cost (the time needed, labor, and materials to be used).

If you want to replace your roof, or your house is under construction, and you would like to know the cost or square, I will show you an excellent method of calculating your square roof footage.

However, it is essential to note that the best way to get a correct measurement is by hiring a local roofing contractor to measure the roof.

Here are some highlighted steps to calculate your square roof feet:

### Step-1

#### Find out the footprint of your house

To do this, count the number of steps to take for your house length to be gotten. Do the same to get the width.

When you have gotten the figures, multiply them to determine the home’s footprint. That is length X width = footprint.

This method is not very accurate, but you will have an idea of the home’s footprint.

### Step-2

#### Always remember the roof’s slope.

The makeup of the roof is something you should remember when calculating roofing squares. For an accessible and walkable roof, multiply the roof’s footprint by 1.3 to find the square footage.

For a roof with a low slope, multiply the footprint by 1.4 to calculate the square footage. Finally, if itâ€™s a steep and complex roof, the footprint should be multiplied by 1.6 to get the houseâ€™s square foot.

Another step is calculating the roof pitch. Roofs have either low, medium, or high. A low pitch will rise three inches in every twelve inches of horizontal base length.

A medium pitch rises six to nine inches of every 12-inch base horizontal length. High pitches are more than nine inches.

### Step-3

#### Calculate the roofing squares

Now that you know the footprint of your home with the slope and complexity in mind, I will show you the method of calculating your houseâ€™s square footage. Use this equation for getting your roofâ€™s square footageâ€™s rough estimate:

Length of home X width of home = footprint of your house

The footprint of your house X slope and complexity = square feet of roof.

For instance, if your roof is an easy and walkable one and your house measures 58 feet in length and 30 feet in width, this will be the look of your calculation:

60(length) X 28(width) =1680(footprint)

1624 X 1.3 (easy and walkable roof) = 2184 (square feet of roof area).

This equation will not be 100% accurate. However, knowing your roof’s square footage is an excellent starting point for learning how to calculate roofing squares and how much you will invest if the need for replacement arises.

## How Many Bundles Of Shingles Do I Need?

The number of bundles you will need is dependent on the surface area and slope of your roof.

Determining how many bundles of shingles cover your roof is analogous to determining how much wallpaper is needed for your walls.

You can do this by finding out the area of your roof and dividing it by each package of shingles ( there are three bundles of shingles in each box).

However, if your house is a newly constructed one, you can get the area of your roof by checking the architectural drawing.

As simple as it sounds, getting the measurement is difficult. You can do this by getting on the roof, taking measurements, and summing them up. The slope of your roof is an essential factor to put into consideration.

A steep roof of 1000 square feet will require more shingles than a lower sloped roof.

With recent advancements in technology, you can get an accurate roof area measurement using satellites or drone images when appropriately calibrated. Roof areas are called squares, simply 100 square feet of roof area.

Shingles are packaged so that three bundles can cover one square of roof area.

You should read the label carefully because certain brands require more than three bundles to cover a square.

For example, a brand may have 24 shingles in one package, and another brand may have 26, the one having 24 could cover up more roof area than the one with 26.

The most important thing you should look out for is the area covered per bundle. This information is always displayed on the label.
