In practice, flat roofs do not need to be absolutely level to allow water drainage. Roofs can be classified into the following categories: For instance, a pitch of 1:12 indicates that the rise will be equivalent to one yard for every twelve yards of building length. In the form of x:12, we commonly state the roof pitch as a ratio between rising and run. We can measure it in two ways: as the angle formed by the rafter with the horizontal, or as the ratio of the rise to the run of the roof. The slope generated by the rafter is known as roof pitch. Take a look other related calculators, such as: This roof pitch calculator may also convert roof pitches from degrees to percent. We’ll walk you through the procedure of determining the roof pitch step by step.
Our roof pitch calculator is a useful tool for determining the pitch of your home roof and the length of rafters you’ll need for your building project.
