A standard roof pitch ensures perfect safety to construction because it creates effective water drainage mechanism.
Roof pitch is a measurement of a roof s slope expressed as a ratio.
High pitched roofs are hazardous to work on which may add to the cost of repairs or replacement.
The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.
To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

A high roof pitch is also more aesthetically pleasing on ranch houses giving them additional visual height to carry the eye upward.
Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
