If you want to determine roof slope, it isn’t as difficult as you may think. In fact, it’s quite simple and can be done in a very short amount of time. Since it means being on a ladder and can be rather intimidating you will probably want to hire a professional.. The slope of a roof is measured as the length that a roof rises vertically over a 12″ horizontal distance.

Determine Roof Slope, But Maintain Ladder Safety. 

To determine roof slope, a ladder is placed at the side of your house so that you may easily access the down slope edge of the roof. At this point, you should be in line with the roof’s peak, which means the roof should slope up from left to right or from right to left, but not away from you. No matter who is taking the,measurement its important to make sure that your ladder is secured. Both hands are needed to determine roof slope and  being distracted by a shaky ladder can be very dangerous. When working on a ladder, make sure that it’s perfectly safe. If you have trouble with heights and do not wish to climb the ladder yourself, call a roofing professional.

How To Determine Roof Slope Accurately

Now that you’re ready to get started. The measurement begins by holding a framing square onto the roofline while making sure that the long end of the “L” is pointing toward the roof’s center and the short end is pointing down toward the ground. The long end of the framing square should meet the edge of the roof at the 12″ line. Level the square horizontally and read the measurement on the short end.

To determine roof slope, remember that rise is the measurement on the vertical leg while run is the 12″ measurement on the horizontal line. If you are using a framing square, keep in mind that some have measurements on both edges. If that is the case with your framing square, consult the measurements on the inside edges for an accurate number. Remember that, if your roof rises 8 inches vertically for every 12 inches horizontally, then you can determine roof slope to be at 8/12.

If you do not have a framing square to measure roof slope, a ruler or tape measure will also work because the slope is measured based on a 12″ horizontal distance. If you are using a tape measure, look for one that has a push lock. This will help avoid unnecessary problems with constantly having to pull the tape measure back out to double check the slope measurements.
