How do i figure out square footage of a roof.

The roof area for a hip end is the same as for a gable end the intersection is equivalent to a hip slightly conservative so there is usually no need to consider triangles when measuring a roof. The calculator cannot account for complex shapes based on a measurement of square footage alone. This is simply 100 square feet of roof. Our roof calculator uses base length and base width to find the estimated area.

Get the square footage of roof and divide it by 100 and it will give the number of squares you need and for every decimal number over 3 buy a bundle to achieve the amount of material. Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area. Multiply the length by the width to arrive at the ground area of the house. The first step in a free roofing estimate is measuring the roof dimensions.

1square of roofing covers 100 square feet of roof a bundle is 1 3 of a square. In cases where a roof has a complex shape such as in the image to the right measuring the dimensions and areas of each part of the roof to calculate total area will result in a more accurate measurement of area. A square simply refers to a 10 x 10 square of roofing. To find the squares divide the overall roof area by 100 and then round up.

The roof area is simply 114x18x2 plus 30x18x2 giving 5184 square feet which is perfectly adequate for estimating materials. For example take an area made up of a triangle that s 20 feet high and has a base of 40 feet plus a square that s 40 feet by 40 feet. Calculate the square footage of a gambrel style roof using imperial measurements. The base width is the distance from one corner of your roof to the other at its base on the short side of your house.

Keep in mind that the average size of a roof is 1 700 square feet so your total will likely be 10 higher or lower than this figure. If the house has an irregular shape measure each part separately figure the separate areas and add them together.
