Roof Options for Earthbag Buildings
For small round/circular earthbag homes/buildings, an earthbag dome for the roof is practical. However, when the span of the roof becomes big, or the building is not circular, a framed roof is recommended.
Examples of framed roof are:
- Roofs for earthbag buildings could be done with any type of construction material used for other types of construction such as:
- Lumber rafters or lumber trusses.
- Timber beams
- Log rafters and log trusses
- Bamboo rafters and trusses
- Light gauge steel rafters or light gauge steel trusses
Please note that:
- Earthbag walls must be anchored to the roof or floor at their tops.
- Using concrete bond beams on top of the earthbag walls with 2- #4 reinforcing bars is highly recommended.
