What is a Butterfly Roof?

A roof with a double slope that slants upwards near the edges, designed to resemble wings of a butterfly.  It is a roofing detail which is shaped like two upside-down “L”s  joined together to form a shallow “V” shape.

A butterfly roof offers a unique design touch to a building. It typically has a gabled roofline, and is used on many high-rise buildings.

The butterfly roof has a gentle curve that can be seen from the exterior of the building, often giving the building a distinctive and eye-catching appearance.

It is made of materials like aluminum, steel, zinc, copper, and lead-coated copper

A butterfly roof is an architectural roofing detail which is mostly used on multi-story buildings.

The butterfly roof, which is also known as a butterfly roof drain, is designed to allow rainwater to flow off the roof. This roof design is also beneficial because it prevents buildup of water.

When a heavy downpour does occur, runoff water will flow off the edges of the roof. This prevents water from backing up under the roof and causing damage.

A butterfly roof ensures that there is no wetting of the lower portion of the roof when it rains as rainwater runs off from the steep upper pitched portion and drops into a gutter which directly dumps it onto the earth below.

This means that the lower part of the roof remains dry and this greatly reduces health risks associated with mould and mildew.

This roofing system is ideal for areas that have high temperatures throughout the year because it allows for greater air circulation in the attic which helps eliminate moisture as well as reducing heat build-up and temperature extremes.

This is a great advantage, especially in places such as New York where temperatures can get very high.

Some cons of this design are that it takes a long time to install and it is not easy to repair if there is a leak.

Because of their complexity, they can cause a higher roof/ceiling clearance, which may make some people not to install them. Butterfly roofs may have a high cost in terms of installation, maintenance and repairs.

Why Install a Butterfly Roof?

The main advantage of installing this type of roofing is that it encourages rainfall to run off the roof instead of soaking into it which can cause premature deterioration.

It also has the advantage of increasing the volume in the attic which in turn increases the size of a living space.

It is a very popular roofing system today due its low cost, ease of installation and time-saving benefits.

Flat roofs are not ideal for collecting rainwater because they do not allow water to run off evenly, when rainwater falls it causes the upper slab portion to be saturated more than that on the lower sides.

This can lead to roof leaks as well as the water dripping onto the ground causing floods when it rains.

Butterfly roofs are a better solution for collecting rainwater because they have a sloped valley which allows water to run off from the roof instead of saturating the upper portion of the roof.

Rainwater simply runs down into a gutter and is deposited directly onto the ground below. This means that the water distribution on a butterfly roof is not only more even, but the volume of water that is collected goes towards building up the living space.

Benefits of Butterfly Roofs

Butterfly roofs are well suited to high pitched roofs and are particularly popular with tropical homes. It offers better protection against heavy winds because it has more space for ventilation. That being said, there are many advantages of butterfly roofs that make it more preferable than traditional roofs:

  1. They increase attic space
  2. They can be used to build a more spacious home
  3. They reduce cooling costs, because they allow more air to circulate between rooms
  4. They can provide better insulation of the attic space
  5. They are equipped with low-profile gutters, which means they will not excessively cover the roof and conserves rainwater.
  6. Butterfly roofs shed rainwater well because of the two angles that increase its ability to drain water from the attic space.

Butterfly Roof FAQs

1. What is the purpose of a butterfly roof?

The purposes of a butterfly roof are to collect rainwater and trap air in the attic or living space. A butterfly roofing system is designed to collect water in the core of a building (generally in a specifically created holding tank).

After being filtered, the collected water can be used for watering plants, bathing, or even drinking. Keep in mind that this requires certain facilities in order to function properly.

This helps to keep down the relative humidity of the room, control moisture, reduce thermal loads and improve comfort.

2. How do butterfly roofs drain?

This spectacular roof design has two downward sloping roof surfaces that meet in a central roof valley, resembling the wingspan of a butterfly.

As rainwater drains into the center roof valley, the butterfly roof eliminates the need for typical gutter and downspout systems.

3. How is it different from other roofing systems?

The main difference between other roofing systems and butterfly roofs is that the butterfly roof has two slopes.

This steep slope directs water to the center roof valley where it will be collected in gutters and drained directly onto the ground.

The lower slope has a shallower pitch that helps to minimize contact with water, reducing the risk of damage to both living space and roofing materials from moisture.

4. Are butterfly roofs expensive?

The complexity of the design raises the cost of the butterfly roof. Not only would the initial costs be higher than with traditional roofs, but maintenance will also be more expensive.

5.  How do butterfly roofs drain?

The shape of the roof prevents water from pooling and being collected in one location. Functionally, the butterfly roof eliminates the need for traditional gutter and downspout systems as rainwater drains into the central roof valley.

This is different from a typical roof which would collect water in one corner.

6. Who invented the butterfly roof?

The modern butterfly roof is widely attributed to William Krisel and Dan Palmer in Palm Springs, California, in the late 1950s.

It is estimated that beginning in 1957, they built about 2,000 homes in a sequence of developments known as the Alexander Tract, which historian Alan Hess describes as “the largest Modernist housing subdivision in the United States.”

Krisel agrees that, while his work popularized the style, he was not the creator of it.

7. Name some advantages of a butterfly roof

The main advantage of installing this type of roofing is that it encourages rainfall to run off the roof instead of soaking into it which can cause premature deterioration.

It also has the advantage of increasing the volume in the attic which in turn increases the size of a living space.

8. What are some disadvantages of a butterfly roof?

11. Explain the process of installing butterfly roofs

Butterfly roofs can be manufactured in both metal and concrete on a large scale as well as being installed individually.

The main difference is that the corners on metal butterfly roofs are defined by PVC and have no cover while the concrete version has more complex shapes with varying angles.

These differences also make it easier to install metal butterfly roofs because they can be cut to size, but it requires more time and skill when it comes to concrete Butterfly Roofs installation.

Butterfly roofs are installed on an individual basis by one member of the design team.

12. Are butterfly roofs maintenance stable?

The shape of the roof makes it more difficult to maintain and repair, but that is not a definitive disadvantage.

The main disadvantage is that the system can have a high cost in terms of installation and this may also be a factor when it comes to the maintenance process as well.

13. What are some problems of butterfly roof?
