8 inches and you have an 8 in 12 pitch.

How to measure roofing materials.

Roofing contractors estimate projects and materials by the square so it is crucial to find this measurement to accurately estimate the amount of material needed. Pitch measurement method 1. Dividing 1 290 sq ft 120 m 2 by 100 for example will tell you that you need to order at least 13 squares to get the job done. If this distance measures 4 inches you have a 4 in 12 pitch.

First measure the length and width of each surface on the roof then multiply these values to get the square footage of that surface. To find the squares divide the overall roof area by 100 and then round up. A square simply refers to a 10 x 10 square of roofing. Divide your estimated square footage by 100 to estimate your materials.

This is simply 100 square feet of roof. 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. Since it takes 3 bundles of shingles to cover a square plan to purchase 3 bundles for each square. 1 roof square 100 square feet.

So if you divide your answer of a product of length times height by two you will get the area of a triangle. Roofing materials are bundled in squares that contain enough shingles to cover 100 square feet 9 3 m 2. Then add 10 to the number to account for waste. To estimate roofing materials start by finding the total square footage of the roof and divide the number by 100 to determine the number of squares in the roof.
