Standard Ranch House Roof Pitch

Barb traditionally ranch style homes had a consistent low roof pitch.

Standard ranch house roof pitch.

Conventional roofs are the easiest to construct and you can walk on them safely. The steeper the roof the more expensive the trusses get because the longer the boards get and the more roof area increases. This is the distance between trusses. You can also calculate roof pitch even without using a roof slope calculator.

Commonly it is 3 4 th of span as per gothic rafter must be equal to span. 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. Gable roofs offer the advantages of easily shedding rain and snow in cold climates. 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.

Usually average roof pitch is determined using the same roof length method. The standard roof truss spacing is 2. Gable roofs on ranch style homes can have a variety of pitches from low to steep. Pitches above 9 12 are very highly angled and are designated steep slope roofs.

Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. 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. They have a pitch ranging from 4 12 to 9 12. Greek says one must keep rafter length in range of 1 9 to 1 7 th of span but as per roman style the standard dimensions are kept about 1 3 to 2 9 th of span with an angle of 23 to 24 degree.

Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. Roof pitches can be as high as 12 12 according to the mhimperialhome website. The most commonly used roof pitches fall in a range between 4 12 and 9 12. High pitched roofs often need extra fasteners and their pitch can be as high as 21 12.

Occasionally you see a ranch with a 6 12 but just as often they have a 3 12.
