How Many Square Feet Is In A Roofing Square

So What Is A Roofing Square

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

A roofing square is a measurement, but it has nothing to do with square feet, meters, yards, or miles. A roofing square is commonly used by roofing companies and is roughly equivalent to 100 square feet. This measurement does not change whether it is a square of shingles or a square of tarp. This is because roofing squares are used to make calculating the cost of materials and labor easier than if you had to use square feet or yards.

Draw Each Shape Individually Calculate Each Area And The Total Square Footage Of Your Roof

Now we have eight shapes to find the area of six triangles and two rectangles. Instead of breaking out the old textbooks to calculate triangle areas, we like to use a triangle calculator. It makes figuring out the area of triangles a lot simpler.

In the example above, we have two triangles with sides of 30, 20, and 20 feet. Pop those figures in the three-sides calculator and youll get an area of 198. Since we have two of those triangles, multiply by 2 for a running total of 396 square feet.

We have four remaining triangles, all with dimensions of 15, 20, and 25 feet. That same calculator reveals a result of 150 square feet. Since there are four of those triangles, multiply by 4 to get 600 square feet.

Lastly, we have two rectangles of 15 by 30 feet. This one is easy, just width times height for a total of 450 square feet for each one. Multiply by 2 and their total square footage is 900.

Adding all the areas up yields a total of 1896 square feet . Since roofing material comes in 100 square foot squares, youll need at least 19 of them for your roofing project. Itd be wise to get at least 20 to account for mistakes and waste.

Installing Roof Shingles In 11 Steps:

  • To start installing shingles, line up aluminum drip edge flush with the edge of the roof and make a pencil line at the top on each end of the house.
  • Using the chalk line, snap a line between the two marks to get a straight edge.
  • Pull the drip edge down about a half-inch from that line to create a gap between the drip edge and the fascia board.
  • Nail the drip edge in place using 1ü-inch galvanized roofing nails and a hammer.
  • Repeat steps for gabled ends, installing the drip edge up the roof along the gable.
  • Lay out 30-lb. asphalt roofing felt paper and nail it in place using 1ü-inch galvanized roofing nails.
  • To lay out the design for the shingles, begin at the bottom of the roof and place a tape measure ý inch from the edge of the roof to ensure the shingles overhang the drip edge.
  • Using the chalk line, snap a straight line on each 5-inch increment.
  • Use the chalk line to snap a straight line vertically every 6 inches.
  • Install a starter course by cutting off the three tabs on a shingle, leaving only the top tar section.

    A common question we get at Roofing Solutions is to define the term roofing square.

    Whats a roofing square? How big? In feet? In yards?

    In the roofing industry, the term square is unique. It does not refer to squared feet. Nor does it refer to squared yards.

    Instead, a square is a term of measurement all its own. One roofing square is equal to 100 square feet.

    So, in a sense, were talking about square feet, but using this unit makes it easier to calculate the footageor required materials and cost of a roofing project.

    Varying Roof Styles Make The Term Roofing Square More Common

    Another reason that you cant always divide square footage by 100 to get the number of square is because every roof shape and style is different

    For example, measuring a gable roof is fairly straightforward, but measuring a gambrel or mansard style roof can be a bit more complicated. Waste becomes a major factor when measuring more intricate roofing types like mansard and hipped roofs. Waste happens when shingles need to be cut to fit tight spaces . They are not always nailed in even rows along the roof deck.

    With more complex roof types, you quickly realize that not every square foot of measurement is created equal! Overall, the phrase roof square helps bridge the gap for projects both simple and complex.

    As long as you have an experienced roofing contractor to work with, you can breathe easy knowing that at the end of the day, the correct amount of materials will get delivered and that your roof installation will go 100% according to plan!

    How Many Homes Fit Into An Acre

    How to Measure the Square Footage of a Roof

    One of the biggest misconceptions that I commonly hear is people thinking that a single acre is equivalent to the size of a standard residential plot of land. While it would certainly be nice for that to be the case, unfortunately, an acre is actually considerably bigger than a residential plot.

    The median lot size for an average family home in the United States is roughly 8,276 square feet, which is equal to about 0.19 acres. This implies that you can fit around 5.5 standard homes into a single acre.

    With that said, keep in mind that this is the standard size for a family home in an urban area. Finding homes in the countryside that are bigger than this is quite normal, as they can often be nearly double in size.

    How Can I Figure Out The Square Footage Of My Roof

    Its been a long time since high school trigonometry, but take it from the leading Northern VA roofing company, figuring out the square footage of your roof isnt as complex as it sounds.

    The Terminology

    First, youll want to understand a few of the terms you might not have heard before. If youre researching a new roof, its easy to become overwhelmed.

    Pitch/Slope: This is the steepness of your roof. The reason this is important is because this angle will greatly affect the square footage of the roof deck.

    Squares: A square is 100 square feet, or an area 10×10. Roofers use this because its easier to say The roof is 24 squares, than it is to say, The roof is 2380 sq ft. Pricing and materials also tend to be quoted in squares.

    Peak/Ridge: This is the top of your roof. Its not uncommon to instal special ventilated ridgecaps, and if the peak is shingled traditionally, it will require several layers of shingles.

    Gable: The gable is the sloping edge of your roof.

    Eave: This is the bottom of your roof, where the gutters hang.

    The Math

    The first thing you will need to do is figure out the slope of your roof. Unlike, say, engineering the rafters figuring out the slope of your roof is relatively easy.

    Or, you could go outside with a protractor and see which angle matches.

However, an annual inspection by a professional expert will reveal any flaws or damage to your roof that you were not aware of and allow you to “nip it in the bud” before it gets worse.

    Inspectors will check for shingles that are not correctly secured or bent, bowed, cracked, or broken. They’ll also look for missing flashing in the eaves, roof cement around chimneys and vents that have developed cracks from hail, and other telltale indications.

    Headlap 1 Square Isnt Always Exactly 100 Square Feet

    What is a Roofing Square? (How Big)

    If youre hiring a qualified contractor for your project, then you dont need to worry about this, but if youre replacing your own roof you need to understand headlap!

    Earlier we mentioned that a roofing square is equal to 100 square feet. While true in most cases, this calculation does not consider headlap.

    What is headlap? Headlap is the overlap of a row of shingles on top of the next row, which helps protect against water penetration. Because of headlap, a square of roofing shingles never really equals exactly 100 square feet of roofing when you line all the materials up.

    Put plainly as possible: one square of roofing is not 100 square feet exactly, but is enough to cover 100 square feet of roofing area. The materials themselves may, and often are, more than 100 square feet in total.

    How To Measure A Roof And Determine How Many Squares Of Shingles Are Needed

    When installing a new roof or paying a professional roofer, the magic number is the number of squares of roofing shingles. A square of roofing is equal to 100ft2 of asphalt shingles. Roofers will typically charge based on the number of squares of roof in need of installation. Other factors include whether the roof can be walked upon without ropes. If a roof does not require cable for workers to be safe, it is called, walkable. And vice versa, non-walkable. If a roof already has a layer of shingles, another layer of shingles can be laid-over the old layer of shingles. The shingle installation is called a lay-over. Obviously a lay-over cost less because the labor and dumping costs are less.
