Multi-gabled roofs are exactly what they are: a roof which has more than one gable. Either in series or in parallel, or leaning to another roof. You typically see multi-gabled roofs in medium-sized railway stations. Whether in standard or saw tooth form, they are a common sight in 19th century and early 20th century factory buildings. They can also be nested.
M-Type, Ridged or Multi-Gabled: What’s The Difference?
Structurally, there is little difference. An M-Type is a multi-gabled roof, though one that happens to have a distinctive ‘M’ shape. A ridged roof could be a factory roof in the saw tooth form, though it is ultimately a multi-gabled roof. The difference in pitch style is obvious. The slant in a multi-gabled roof may vary.
Where would you see multi-gabled roofs?
A fair number of railway stations have multi-gabled roofs as an alternative to barrel roofs. These are either seen across the lines or following the lines. The roof at Carlisle Citadel station is a fine example with small gables spanning across the lines. In Edwardian times, multi-gabled roofs were popular with factory buildings and football grounds.
