Standard Ranch House Roof Pitch

In the roofing trade the go to term is pitch and it is expressed in terms of 12 inches so the pitch of a roof is determined by how many inches the slope rises for every 12 inches it runs horizontally.

Standard ranch house roof pitch.

The standard roof truss spacing is 2. Usually a 4 12 either hipped gabled or with a dutch gable. Pitches above 9 12 are very highly angled and are designated steep slope roofs. High pitched roofs often need extra fasteners and their pitch can be as high as 21 12.

Gable roofs offer the advantages of easily shedding rain and snow in cold climates. Conventional roofs are the easiest to construct and you can walk on them safely. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. Hipped roofs are also common which offer a slightly different design and lower pitch.

Commonly it is 3 4 th of span as per gothic rafter must be equal to span. You can also calculate roof pitch even without using a roof slope calculator. The most commonly used roof pitches fall in a range between 4 12 and 9 12. The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Roof pitches can be as high as 12 12 according to the mhimperialhome website. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. Barb traditionally ranch style homes had a consistent low roof pitch.

Usually average roof pitch is determined using the same roof length method. Occasionally you see a ranch with a 6 12 but just as often they have a 3 12. They have a pitch ranging from 4 12 to 9 12. This is the distance between trusses.

You will also incur additional costs because it is much harder to deck and shingle a roof that is 12 12 pitch versus a 4 12 roof.
