Flat Roof Design Detail – Flat roof is a flat roof with a slope of less than 10 ° C. This type of roof is normally made from concrete, but because of its practical structure, it’s often useful for roofs with polycarbonate material. This sort of roof is widely utilized in temperate subtropical soils with little rainfall. There are many types of flat roof grating structures, including the usage of conventional reinforced concrete, front concrete (aerated) with aerated lightweight concrete or composite concrete (mixed with other materials such as steel wire reinforcement or styrene).


  • Most of it’s more practical due to its smooth shape, so the frame is not too complicated.
  • May be used for various roofing needs as the slope is not too steep so it’s flexible to be placed anywhere.
  • Maybe there’s a solution to cultivate a house. Narrow spaces with plenty of space make flat roofs a way to develop new activities on the roof of a house. Noteworthy would be the structures which can be shown for future loads.


  • Unable to drain the water causing patches that enable leakage.

Solution: When designing a ceiling, you need to make a roof slope of at least 2o to allow water to flow straight to the sink. Drains must certanly be provided at the edge of the roof to prevent stagnation from rainwater and concrete damage.

  • Concrete is a material with poor heat absorption, which causes the temperature in the lower chamber to become hotter.

Solution: To minimize the heat generated by the concrete ceiling, it is advised to supply 30-50 cm air gap involving the ceiling and ceiling so that the hot air generated doesn’t flow straight into the room.
