What Math Do Roofers Use?

When it comes to roofing, there’s no denying that math is an important part of the job. From calculating angles and measuring materials accurately to budgeting for a project, math skills are absolutely essential for any roofers – but what specific kind of math do they use? We’re here to break down all the mathematics used in roof work.


The most obvious math application in roof work is geometry. Roofers need to be able to calculate angles when laying shingles and know how to measure areas accurately. This includes working with standard two-dimensional shapes such as squares, triangles, rectangles and circles, as well as more complex shapes like hexagons and octagons. Knowing how to properly cut these shapes into sections and properly lay them on the roof helps mitigate issues with water runoff later on.


Trigonometry is another subject that comes in handy for roofers since it requires calculating angles related to right angled triangles. This type of mathematics can help roofers measure pitches (the angle at which a roof rises) and angles for gables or dormer windows. It also applies when measuring heights from the ground up or when dealing with roofs at different elevations from each other (such as between two stories, a porch or a carport).

Algebra and Arithmetic

Algebra and arithmetic are both important topics for doing any kind of calculations related to budget estimations or measurements for materials needed for a job. For example if one side of the house needs 8 bundles of shingles (which usually come in packages of 3) then you will need 3 x 8 = 24 bundles total; this is just basic algebra! Arithmetic also comes into play when determining how much trim material will be needed around doors or windows based on measurements provided by architects or building plans.
