There are several methods for calculating the square footage of a roof. The first is to measure the base, which is the bottom edge of the roof. Then, multiply the length and width of each section by two. For example, a roof that measures 10′ wide and 10′ high has a base area of five feet by a height area of four feet. This will give you a roof area of ten square feet.
The most accurate method for calculating the square footage of a roof is to measure each roof plane. For example, a rectangle-shaped roof has a length and width that add up to a total square footage of 6-9 square feet. Once that is done, multiply the total square footage by two and add it all up. However, if you’re not able to take the time to measure each plane, you can estimate the number of bundles by measuring the building’s length and width, including rake-edge overhangs.
Another method for calculating roof square footage is to use an overhead sketch. In doing so, you can see the different angles of the roof and how they affect the size of the roof. A single-slope roof or a simple gable roof is relatively easy to calculate. A complicated roof line will require multiple pitch angles. To get an accurate estimate, you must make sure to include the square footage of each floor and the roof’s perimeter.
The next step in calculating roofing squares is to determine the total square footage of the roof. To do this, you must first determine how much the roof is. Using this information, you can then divide the square footage by 100. For example, if the roof area is 1000 square feet, then you would need one square of roofing material for a thousand square feet of roof surface.
Another method is to hire a roofing professional to do the measurement for you. Some manufacturers offer roofing square calculators online for free. The calculators will provide you with the approximate square footage of your roof. Then, you can use these calculations to determine the cost of materials for your roof. You can also use your own measurement of the roof’s square footage.
After you have determined the area of your roof, your roofer can then determine the square footage of shingles. This will be important when ordering roofing shingles. The area of each plane on your roof will vary depending on the type of roofing. A gable roof will have fewer planes than a hip roof. In addition, you must take into account any overhangs.
