Surface Area Of A Roof Calculator

Online calculators and formulas for a surface area and other geometry problems.

Surface area of a roof calculator. 10 x10 100sf 1 square roof area calculators. 40 to 60 years heavy requires a stronger roof structure other factors that can affect a roof s lifespan. If using this calculator to compute the surface area of a hollow sphere subtract the surface area of the base. The area calculator can be used to calculate the area of a variety of simple shapes that together can comprise the area of the roof.

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. This applies to lengths as well as areas. Calculate the unknown defining side lengths circumferences volumes or radii of a various geometric shapes with any 2 known variables. A roof with a high pitch can last longer because snow and rain can not settle on the roof.

Heavy requires a stronger roof structure concrete tiles. The surface area formula for a cone given its diameter or radius and height is π x diameter 2 2 π x diameter 2 x diameter 2 2 height2 where diameter 2 is the radius of the base d 2 x r so another way to write it is π x radius2 π x radius x radius2 height2 as seen in the figure below. Our roof calculator uses base length and base width to find the estimated area. Using the aggregate area of these simple shapes can yield a more accurate roof area to be used with the roofing material calculator.

Spherical cap sa 2πrh base sa πr 2. In general you can skip the multiplication sign so 5x is equivalent to 5 x. Given two values of height cap radius or base radius the third value can be calculated using the equations provided on the volume calculator. Fortunately if you know the roof s pitch or have access to the home s attic to measure its incline you can arrive at an accurate roof area calculation using sketchandcalc.

This calculator will help you determine the amount of square feet you have for replacing roof shingles. Calculator online for a the surface area of a capsule cone conical frustum cube cylinder hemisphere square pyramid rectangular prism triangular prism sphere or spherical cap. And that s the number you were looking for. Take the area of the roof s footprint say it s 5 000 square feet and multiply 5 000 by 1 118.

The calculator will find the area of the surface of revolution around the given axis of the explicit polar or parametric curve on the given interval with steps shown. That gives you 5 590 square feet which is the actual area of the surface of the roof. Roof shingles are figured by number of squares. You want a roof area calculator that provides accurate estimates to help you order materials such as shingles membrane roofing or ceramic tile.

Darker colors absorb more heat so they last less. Gable hip shed for each of the roof types pictured below l horizontal length w horizontal width and h vertical height all entered in feet.
