Butterfly roofs took flight from boxy norms in the 1950s and have made a solid landing in modern interpretations
Sharp angled roof lines that incline to the center create a butterfly roof. Popular following the atomic age, this midcentury roof design was a response to the boxy brick facades of the postwar norm. The crevice at the center of the sloping roof was able to collect water in drought-affected areas, and the sharp angles allowed for fantastic vaulted ceilings.
This butterfly roof has equal-length sides and acts as an eave for the covered deck below.
The downspout of this butterfly roof shows where the water will run off, right at the crevice where the two slopes meet.
This is an example of a modern butterfly roof. The lines of the structure are long and low, characteristic of modern design.
Tongue and groove panels line the eaves of this contemporary butterfly roof.
Though this looks like a butterfly roof, it is actually comprised of two skillion roofs, which both slant inward. The advantage of this is that the vertical space between allows for a nice clerestory window.
