What is a Butterfly Roof? What is a Butterfly Roof?

A butterfly roof is house roof design that is built by joining two roofs with its edges elevated at a certain angle that allows it to form a valley slope. From the front of the structure, the roof looks like the wings of a butterfly. The roof is designed in such a way that the joining point is at a lower level compared to the outer boundary of the roof, resembling a water reservoir.

This American roof design was first implemented in 1933. Over the years, it has continued to develop and many versions of the roof exist. These include saddle roof, shed roof, gable roof, zigzag roof, and low pitch butterfly roof. The butterfly roof design ensures the interiors feel fresh and airy. Moreover, full sunlight can be achieved thanks to the increased height of walls and windows. In the earlier days, these roofs were used to hold water. The butterfly roof was designed to capture rainwater in the central valley of the roof. This water was then used during periods of drought.

The disadvantage of having a butterfly roof is that leakage or blockage in the drainage system can cause severe problems to the pillars as the weight bearing strength of the pillar decreases. This is the main reason why such roofs have not been able to become popular, despite their modern appearance.
