How to measure a triangle roof.

For example if the roof slopes up from the front of a. Locate the level s 12 inch mark. 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. Access one of the rafters then take the measurement this way.

If you have a roof section that s 30 feet 9 1 m long and 12 feet 3 7 m high multiplying those dimensions would give you an area of 180 square feet 17 m 2. Pitch measurement method 1 1. If this distance measures 4 inches you have a 4 in 12 pitch. So if you divide your answer of a product of length times height by two you will get the area of a triangle.

L 30 feet h 12 feet 30 12 2 180 square feet. 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. Determine the distance from the edge of the roof to a point on the same plane directly under the highest point.

The most precise way to find the roof s slope is by measuring it from the underside. The length l times the height h of a triangle is twice its area a2. 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. For trapezoidal roofs measure the bottom edge the top edge also known as the ridge and the distance between the 2 edges.
