If you’re planning to replace your roof, you may be wondering how many squares of roofing do I need. Although squares have nothing to do with feet or meters, yards or miles, a square roof is about 100 square feet in size. This makes the task of measuring roofing materials easier. In addition, a roofing square can be used for both shingles and tarps. Depending on your project size, you may require more or fewer squares for some roof types. roofing calculator
When estimating the square footage of your roof, the simplest way to calculate the squares is to measure the area of the existing roof. If you’re replacing an existing roof, you can use the square footage of the roof sheathing to get a rough estimate of the total square footage. One complete piece of roofing sheathing is four feet squared, while two squares are equal to eight square feet.
A shingle bundle contains 15 to 29 shingles, which is equal to about 33 square feet. There is waste material, which you need to cut off or overlap. Then, divide your total square footage by 33 to get the number of bundles you need. You should also purchase roofing underlayment and nails to complete your job. If you’re unsure about the square footage needed for your roof, you should consult a roofing contractor.
You can also use a roofing calculator. To calculate how many squares of roofing you’ll need, measure the roof as if it were flat, but take into account any slope and sloping. Multiply this number by 100 to get the squares needed for the roof. This way, you’ll be sure to have the right amount of roofing materials on your roof. But if you’re unsure, you can use a roofing calculator offered by Home Advisor.
You can calculate the square footage of the roof by measuring the dimensions of each plane. If your roof is a rectangle, then you’ll need four squares, while a complicated roof is a combination of several different shapes. For steeper roofs, you can estimate the square footage by measuring the building’s length and width. Take note that steep roofs are often dangerous, so use safety gear while measuring.
A good rule of thumb is to add about 10% to 15% to the total amount of shingles. The waste factor will be higher if the roof is more complex, so you’ll have more cut shingles on the edges and corners. Save extra shingles for future roofing repairs or damage. As a rough guide, a twenty-four square-foot roof would require 2.4 squares of roofing shingles. If you’re using roofing underlayment, you’ll need a similar number of rolls of roofing underlayment.
You’ll also need to consider the location of your roof. The climate in your region may require more roofing material than a square in the same area. It’s recommended that you contact a professional roofing contractor to receive accurate measurements. In addition, it’s also important to understand that the cost of roofing materials varies according to availability and the price. If you live in a tropical region, the price of roofing material will be much higher than in a temperate one.
