Measuring Roof Size

The length l times the height h of a triangle is twice its area a2.

Measuring roof size.

See the image below for more explanation on rise run and pitch. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12 horizontal inches it runs. It will also give you the perimeter of the shape of the roof. L h 2 area calculating an area of a triangle when estimating a roof.

1 roof square 100 square feet. 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. 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. If its pitch is 6 in 12 a pitch multiplier of 1 12 multiplying 1 152 sq ft 107 0 m 2 by 1 12 would give you an overall square footage of 1 290 square feet 120 m 2.

A 12 in 12 pitch is a steep 45 degree angle roof. A roof s pitch is determined by how much it rises vertically for every foot it runs horizontally. Make sure to document the number of chimneys skylights or other obstructions and include dormers in your measurements. So if you divide your answer of a product of length times height by two you will get the area of a triangle.
