Surface Area Of A Roof

Measure the distance from the surface of the roof to the bottom of the level at the 12 inch mark.

Surface area of a roof.

You want a roof area calculator that provides accurate estimates to help you order materials such as shingles membrane roofing or ceramic tile. Roof pitch affects the actual area of the 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. Many homes have an asphalt shingle roof but some have wood metal tile and slate which can be more expensive.

Roofing material is estimated by the square which is equal to 100 square feet. That gives you 5 590 square feet which is the actual area of the surface of the roof. This would yield 1 3 next square your result. The base width is the distance from one corner of your roof to the other at its base on the.

How roof area is calculated. Place the other end of the level at the peak of the roof and hold it level. And that s the number you were looking for. For example if your roof s pitch is 4 in 12 you would divide 4 by 12.

Start the project with a roof area calculator. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118. If your number is 1 3 squared would yield 1 9. Area is defined as the expanse or measurement of a given surface and there are a few methods for measuring your roof s area.

Determine the slope of the roof. Calculating the surface area of a sloped roof can be time consuming without the right tools. Calculating the area true if you want to get the exact area measurement for your roof you can follow these steps. The average roof is 3 000 square feet or around 30 squares.

And for a roof with a slope of 6 12 that number 1 118 is your roof slope multiplier. Once you have your roof s pitch divide the number by 12. Roof pitch is a determining factor for cost of the roof as well as the roof area and the type of materials used. Multiply the length of the roof by the width to establish the surface area in square feet.

Mark a level 12 inches from one end. This is expressed in terms of how many inches the roof rises for every foot of horizontal distance. For example if the length is 21 feet and the width is 10 feet the surface area is 210 square feet 21. Our roof calculator uses base length and base width to find the estimated area.
