Renovating or replacing roofs seek knowledge of various roof-related terms. And most of us are unaware of such terms. And it leads to the miscalculation of the building cost. Roof squaring is such a term that we arent commonly introduced.

What is a square in roofing terms?

Roof square denotes 100 square feet of roof surface area. This terminology is quite sufficient to calculate the roof replacement cost. However, it also determines the amount of material, time, or labor youll need in work.

Thats not enough to answer your query. Theres a lot more to discuss. If you have a minute, wed suggest going through our article to get your query answered.

Without bragging anymore, lets jump into the discussion!

What If You Have A Steep Roof

To measure a steep roof, use one of the following alternate methods:

Method 1

Calculate the roof length by measuring the exterior walls plus the overhang for the length of the house parallel to the ridge.

Next, throw a rope over the ridge and mark it where it meets each eave. This will give the width dimension to use in figuring your area. This should be done on each roof section containing a horizontal ridge.

Method 2

Determine the roof area by using a mathematical formula that accounts for the roof length, total span, and roof pitch:

  • Determine your roof pitch by using a pitch gauge or a smartphone app .
  • Measure the length of the roof surface, including overhangs.
  • Measure the span of the roof, including overhangs.
  • Multiply the length x the span. The result will be the plane area. Use the chart below to calculate the total area of the roof.
  • Calculate the total roof area Plane Area x Correction Factor = Roof Area
  • What Is A Bundle Of Shingles

    A bundle of shingles is one package of shingles. Shingle manufacturers will package their bundles so that several usually 3 or 4 will add up to 100 square feet. A bundle of shingles will contain anywhere from 15 to 29 shingles, depending on the type and size.

    It is important to note that there is not a uniform number of shingles per bundle. The number of shingles in a bundle will vary tremendously depending on if you have typical 3-tab versus laminated or other specialty shingles.

    A bundle can only be so big. They are designed so that the average person can pick them up and move them, so you will never have one bundle drastically larger or heavier than a bundle for a different type of roof shingle.

    Initially, a bundle of shingles was supposed to cover one piece of roof sheathing 32 square feet. And three bundles would add up to 100 square feet. The advent of laminated shingles, which are much thicker than standard 3-tab, have created bundles with a total area that is less than the original 32 square feet.

    Roof surfaces are measured in squares. A roofing square is equal to 100 square feet of the roof. To determine the number of squares on the gable roof example in this post, divide its total of 2400 square feet by 100 . This means you would need 24 squares of shingles to cover that roof.

    How To Calculate A Roofing Square

    Before beginning, make sure you can safely access your roofif you can’t, contact a roofing professional for help.

    Grab your measuring tape, level, pen and paper, roof safety equipment, and your ladder. With these in hand, you can measure your roof in five simple steps.

  • Determine the number of planes. Your roof is made up of planes. If you have a flat roof, it has one plane. If you have a simple gable roof, it has two planes. The more architectural details your roof has, the more planes you will have to measure.
  • Measure each plane. Find the length and width of each plane. Then, multiply those two numbers together to find the square footage of that plane. For example, a 35 ft. X 36 ft. plane = 1260 sq. ft.
  • Find the total of all the planes. Add the square footage for each roof plane into one total. 1,260 sq. ft. + 1,260 sq. ft. = 2,520 sq. ft.
  • Divide to find the squares. To find how many squares are on your roof, divide the total square footage of all your planes by 100. In our example, the total was 25.2 squares 2,520 sq. ft. divided by 100.
  • Remember the roof slope. Roof slope indicates how steep your roof is and may increase the number of squares of materials you need. Roof slope is calculated by determining how many inches a roof rises vertically for every 12 inches it extends horizontally. For example, if that vertical rise is 4 inches, the slope is 4:12.

    How Many Roofing Shingles Do I Need

    To estimate how much roofing material you need, such as bundles of architectural shingles or rolls of synthetic roofing underlayment, you need to know the total square footage of your roofs surface.

    How to Calculate Total Square Footage of Your Roof

    To find your roofs total square footage:

  • Measure the length and width of each plane on the roof then multiply length times width.
  • Add the square footage of each of the planes together.
  • Example #1: Shed Roof with One Roof Plane

    For example, this shed roof has one roof plane.

    Multiply length times width :

    A x B = 40 x 30 = 1200 sq. ft. for the total square footage of the roof.

    Example #2: Gable Roof with Two Roof Planes

    This gable roof has two planes.

    So to derive the total square footage of the roof, you would:

  • Multiply length times width and length times width to get the square footage for each plane.
  • Add the two planes together.
  • For example:

    • Plane 1 : 40 x 30 = 1200 sq. ft.
    • Plane 2 : 40 x 30 = 1200 sq. ft.
    • Plane 1 + Plane 2 = 2400 sq. ft. for the total square footage of the roof.

    Find The Area Of The Footprint Of The Roof

    To calculate a roofs dimensions, you need to measure the roof as if it were flat, then account for roof pitch, calculate square footage, and finally determine how many squares of material are required for the roof.

    The calculator above can handle all of this, simply enter the length, width, and pitch, and it will determine the size of the roof in squares.

    Start by measuring the roofs length and width in feet as youre standing on the ground. Remember that the length and width need to be found for the roof, not the house, so take into account that the roof overhangs the building.

    Then determine the area of the roof as if it were flat. Multiply the length by the width in feet to get the area measurement.

    Keep The Slope And Complexity Of Your Roof In Mind

    How to measure a roof and calculate square feet. | 01/2020

    You have to keep in mind the makeup of your roof when doing the calculation for the square footage. The steepness and complexity will change the number you multiply the footprint of your home by.

    For example:

    For an easy up-and-over, walkable gable roof, youll multiply the footprint of the roof by 1.3 to get the square footage of your roof.

    For a hip roof with a low slope, you’ll multiply the footprint of the roof by 1.4 to get the square footage of your roof.

    For a steep and complex roof, you’ll multiply the footprint of the roof by 1.6 to get the square footage of your roof.

    How To Calculate Squares On A Roof: Example

    Since it may still be somewhat confusing, lets look at a detailed example so that you can learn where to plug each number in. Lets start with a roof that looks like this:

    For a house that is this shape, you will want to divide it into rectangular planes. There are a few ways to do this, but for this example, we will take the entire left side of the house and the entire right side of the house. This will leave the central area as the third plane.

    The left side measures 20 feet, but only the entire length from the edge of the left side to the edge of the right side is measured at 30 feet. Since we only want the left side, we have to subtract the length of the center area, 8 feet, by the total length, 30 ft, to get 22 ft. This means that the total area of the left side is 20 ft by 22 ft or 440 square feet.

    Doing the same for the right side, we also have one edge at 20 ft. Then, we have the width at 4 ft. This equals 80 square feet.

    Finally, the central area has a length of 8 feet. The width is equal to 20 feet . Therefore the entire central area is 12 feet by 8 feet or 96 square feet.

    Accounting for pitch, the total square footage is 1.29 x 616 = 794.64. However, to calculate the squares, you will have to divide that number by 100 to get 7.95. This is the number of squares and to account for any additional materials, you can round it up to 8 squares. Rounding up can also allow you to accommodate for any overhang or other discrepancies.

    Taking Pitch Into Consideration

    The pitch of the roof is something that must be considered if you want to get an accurate number of squares for your roofing project. If you do plan on measuring yourself, make sure to be careful. Some roofs will have different pitches for different areas depending on the number of slopes and peaks.

    Once you have the amount of pitch estimated, climb onto the roof with a two-foot level. Place the level on the peak of the roof extending outwards above the slope. Make sure that it is centered so that 1 foot will extend out in each direction from the peak. Also, make sure that the bubble is centered so that you have a level and accurate measure. When it is level, take a tape measure and measure the distance between the end of the level and the roof.

    This makes a triangle where you will have a single foot as one side and the distance from the roof up to the level for another. This will give you the amount that the roof pitches because it will tell you for every foot of the roof, the pitch will increase the height amount. For example, if you have 6 inches of height and 12 inches of length, then the pitch is 6/12. This means that for every 12 inches of roof, the height increases by 6 inches.
