This free roof calculator estimates the area of a roof and the amount of materials needed to replace or build that roof. A bundle of shingles is called a bundle. Ft. They can be saved in case the roof is damaged later or if repairs are needed in the future. Example of a gable roof In this publication, you would need 24 squares of subfloor for roofs.
A square roof is an area of 10x10 of roof surface equal to 100 square feet. For example, 2000 square feet of roof area equals 20 square feet. Now you'll want to calculate the area by multiplying the length by the width. For buildings with more complex shapes, you'll need to divide the diagram you made with the size of the house into rectangles and squares to find the square footage of each one before adding them up. If parts of the building are shaped like a triangle or a trapezoid, the formula becomes a little more complicated.
The slope of the roof is a determining factor for the cost of the roof, as well as for the roof area and the type of materials used. In cases where the roof has a complex shape, as in the image on the right, measuring the dimensions and areas of each part of the roof to calculate the total area will result in a more accurate measurement of the area. To estimate the amount of roofing material you need, such as packages of architectural shingles or rolls of synthetic subfloor for roofing, you need to know the total square footage of your roof surface.
Keep the report handy to discuss with the roofers in the future or to review estimates for your next roof replacement or repair.
By using the aggregated area in these simple ways, a more accurate roof area can be obtained for use with the roofing materials calculator. Therefore, although it can be cumbersome, measuring the area and slope of each part of the roof and multiplying it by the corresponding correction factor will result in a more accurate estimation of the materials roofing required.The steeper the roof, the more the slope increases the total surface area of a facet or the entire roof. Now that you've calculated your home's basic roof area, it's time to incorporate the roof slope. In fact, the only way to truly understand why your roof costs what it costs is to know what the roofer takes into account when estimating a roof. Depending on whether the roof area is measured horizontally (possibly from a drawing or a photograph), a correction factor is necessary to determine the actual area of the roof.
Measuring the square footage of your roof is important in roof construction because it's used to calculate the labor and materials needed to complete the job. Repairing or replacing your roof can be costly, especially if you don't know how to calculate your square footage. The complexity of a roof is simply based on the way the roof is cut, for example, the multiple facets, the different inclinations, the slopes, the valleys, the gables, the dormers and the number of floors relative to the ground. Taking into account the slope and horizontal area, multiply the horizontal area by a correction factor corresponding to the slope, as indicated in the table below, to determine the actual roof area to be used in the roofing materials calculator.
