Measuring Roof Size

A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally.

Measuring roof size. 1 roof square 100 square feet. We ll use satellite imagery and trigonometry to calculate your roof s measurements. It will also give you the perimeter of the shape of the roof. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs.

If your roof measures 48 feet 15 m x 24 feet 7 3 m multiplying its length by its width would give you a square footage of 1 152 square feet 107 0 m 2. How to calculate your roof square footage first measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. Roof reports and wall reports made easy. So if you divide your answer of a product of length times height by two you will get the area of a triangle.

See the image below for more explanation on rise run and pitch. L h 2 area calculating an area of a triangle when estimating a roof. The length l times the height h of a triangle is twice its area a2. Each time you add points the area will update and there is a box below that will convert this into acres meters kilometers miles and finally square feet.

A 12 in 12 pitch is a steep 45 degree angle roof.
