Commonly used roof pitches were given names such as using the rafter-length method: Common, the rafter length is 3/4 the span; Gothic, the rafters equal the span; Greek, 1/9 to 1/7th the span; Roman, 1/3 to 2/9ths the span giving an angle of 23Â° to 24Â°; and Elizabethan, the rafters are longer than the span.
