The question is often asked, “How many square feet is a roofing square?” While a simple gable roof is relatively easy to measure, more complex structures such as gambrel and mansard roofs require more complicated measurements. When estimating materials, waste becomes a large factor, especially when cutting shingles to fit tight spaces or nailing them in even rows along the roof deck. The truth is that not every square foot is the same, so knowing how many square feet is in a roofing square can be an effective tool for construction professionals and homeowners alike. roll roofing
In the roofing industry, squares are commonly used in discussions about roof size and cost. It is a simpler way to compare estimates, and many manufacturers have calculators online for roofing contractors. Homeowners can also measure their own roofs to estimate their own costs and find out how much roofing material to purchase. In either case, it’s a good idea to measure the roof first, and then divide it by 100 to get the exact square measurement.
The basic method for calculating the square footage of a roof is to multiply the length and width of the square by ten. For instance, a 35 ft. x 36 ft. plane would equal 1260 sq. ft. Similarly, a ten square roofing square would require ten squares to cover one thousand square feet. For more precise calculations, a contractor can use a specialized software to calculate roofing squares.
To figure out the square footage of a roofing square, measure the roof without allowing the square to fall off. Divide the result by the length and width of the roof to get the total square footage. The number of squares required depends on the roofing style. A simple flat roof is made of two planes. Other styles may have more than one plane. When calculating roofing squares, divide the total square footage by 100.
A roofing square is a useful tool for estimating the size of a roof. It is a standard unit of measurement for roofing materials. A roofing square covers 10 by 10 square feet, so a thirty-foot roof is 3,000 square feet. Obviously, the more squares a roof has, the more material it will cost to replace it. The roofing square is a great way for a contractor to determine the approximate material and rafter connection sizes.
The simplest way to estimate shingle quantity is to measure each plane of a roof. For a rectangle-shaped roof, you can simply multiply the length and width of the building, then add up the square footage of each plane. This method can be tricky if the roof is steep and you are not equipped for the task. Alternatively, you can estimate the bundle quantity by measuring the length of the building from the ground and adding the overhangs.
