A butterfly roof is a type of roof that is shaped like a butterfly's wings. It is made up of two sloping surfaces that meet in the middle to form a valley. Butterfly roofs are often used in modern architecture because they can provide a number of benefits, such as:

* Increased natural light: The sloping surfaces of a butterfly roof allow for more natural light to enter the building, which can help to reduce energy costs.

* Improved ventilation: The sloping surfaces of a butterfly roof can also help to improve ventilation, which can help to keep the building cooler in the summer and warmer in the winter.

* Increased durability: The sloping surfaces of a butterfly roof can help to make the roof more durable, as they can help to shed water and snow more easily.

* Enhanced aesthetics: Butterfly roofs can add a touch of elegance and sophistication to a building.

However, butterfly roofs also have some drawbacks, such as:

* Increased cost: Butterfly roofs can be more expensive to install than traditional roofs.

* Increased complexity: Butterfly roofs can be more complex to design and build than traditional roofs.

* Increased maintenance: Butterfly roofs may require more maintenance than traditional roofs.

Overall, butterfly roofs can be a good option for buildings that are looking to improve energy efficiency, ventilation, durability, and aesthetics. However, it is important to weigh the pros and cons of butterfly roofs before making a decision.
