Step 3 Measure the Ridglines

Measure the ridge lines.

The distance of the ridge lines are necessary to accurately calculate the surface area. On this roof, measuring the ridge on the main area is not necessary as it's length will be the same as the back wall. While it is not necessary to duplicate measurements, it is good policy to measure if there is any doubt.

The length of the ridge on the smaller hip roof section must be measured. If it is not safe to measure the ridges, estimate from the ground or roof edge as accurately as possible. Remember, the more accurate your measurements are, the more accurate your materials list will be.
