How to measure a triangle roof.

Determine the distance from the edge of the roof to a point on the same plane directly under the highest point. For trapezoidal roofs measure the bottom edge the top edge also known as the ridge and the distance between the 2 edges. Find the dimensions of each of the roof s faces. Use a level against the underside of the rafter you re measuring to get the most accurate value.

1 roof square 100 square feet. On a ladder beside the roof place the level a foot or so up the roof hold it level and measure from the 12 inch mark on the level s bottom straight down to the roof. Locate the level s 12 inch mark. If this distance measures 4 inches you have a 4 in 12 pitch.

For example if the roof slopes up from the front of a. L 30 feet h 12 feet 30 12 2 180 square feet. The basic formula for finding the area of a triangle is the base times the height in this case the distance between the base and the peak. The most precise way to find the roof s slope is by measuring it from the underside.

8 inches and you have an 8 in 12 pitch. If the roof has a triangular shape stretch your tape measure along the bottom edge then measure from the peak point down to the center of the bottom edge. So if you divide your answer of a product of length times height by two you will get the area of a triangle. Access one of the rafters then take the measurement this way.
