To understand the x:12 measurement the ratio can be interpreted as follows. The ratio version of a roof pitch is commonly used in countries with imperial-based measurement standards to calculate roof pitch. Roof pitch is generally measured in either angle (in % terms or measured as degrees) or a ratio in the form of x:12.
These include different types of roof designs that can be classified as “pitched roofs” including: This prevents the roof from becoming damaged by a build-up of these elements. These advantages are gained by the steepness of the roof and allow for rainwater, debris, or even snow to naturally slide and fall off the roof. Pitched roofs allow for a few advantages over other types of roofs like flat roofs or sawtooth roofs. A pitched roof is a roof with an incline commonly found on buildings like houses.
