To find out how many square feet are in a square of roofing, you must measure the dimensions of your roof. The length and width are the two primary measurements used to calculate the amount of square footage for your roof. Similarly, the area of a right triangle is the two sides at 90-degree corners multiplied together, then divided by two. The result is the total square footage for your roof. An example of this calculation is shown below. epdm roofing
The first thing to know is that one roofing square equals one hundred square feet. A square is a ten-by-ten-foot area. Therefore, if your roof measures 200 square feet, then you will need two squares. However, the square footage of your building and its roof will differ. Additionally, your roofing square may be impacted by the slope or overhangs on the roof.
When you are calculating the squares for your roof, make sure to understand the concept behind the term “headlap.” It is simply a metric measurement that refers to the amount of headlap between the shingles. It should not be an issue if you hire a contractor to do the job. In general, roofing squares are 100 square feet, but the headlap is an important factor.
A two-food level is useful for this task. Hold the level outward towards the peak of the roof, and you should see a bubble appear in the indicator glass. Then, take that number and divide it by the square footage of your roof. Remember that the number of shingles in a bundle will vary based on the brand and size of the shingles. Brand X may contain more than twenty square feet of shingles, while brand Y could have fewer shingles per bundle.
You can calculate the number of shingles needed to cover a 100-square-foot roof by dividing the total square footage by three. The result is the number of bundles you’ll need for the entire square. Always make sure you leave some room for error if you need to make adjustments later on. For example, you might not have enough shingles to cover your entire roof, so you’ll have to purchase more shingles to compensate.
The total cost of materials and labor per square varies depending on the type of roof you’re completing. When estimating the cost of materials and labor per square, remember to check the manufacturer’s warranty information. If your current roofing material is still under warranty, you might be eligible for a substantial discount. However, if you don’t have enough coverage, you should consult a professional and make sure the material you choose is covered by it.
