Raised Ranch Roof Pitch

Gable roofs on ranch style homes can have a variety of pitches from low to steep.

Raised ranch roof pitch.

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. Hipped roofs are also common which offer a slightly different design and lower pitch. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Raising the pitch of a roof often requires not only tresses but new supports new roofing and in the end a full replacement of the rooftop itself.

Usually average roof pitch is determined using the same roof length method. 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. Gable roofs offer the advantages of easily shedding rain and snow in cold climates. Commonly it is 3 4 th of span as per gothic rafter must be equal to span.

For every 12 horizontal feet the roof changes 8 feet in vertical height. For most home styles roof pitches fall in a range 4 12 a moderate slope up to 8 12 fairly steep. Roof pitch is expressed as a ratio of the amount of the roof s vertical rise over a corresponding horizontal distance called the run pitch is written assuming a run of a foot or 12 inches so the ratio describes how much the roof rises for every foot of its run.
