There are some design requirements to be respected if you want your flat roof to work properly.

  • The slope of a flat roof should be max. 5 degrees and the minimum slope must be at least 2% over the entire roof area
  • Flat roofs must be covered with materials able to withstand corrosion, chemical action and weather conditions
  • They must comply with thermal insulation requirements and prevent water infiltrations and moisture
  • The project should contain exact details of the materials to be used, the structural resistance of the building and the technology to be used for installing the roof
  • In addition to moisture barriers, you should also consider installing double drains that must be incorporated into the roof at a minimum depth of 5 mm
  • A flat roof must be designed to withstand dynamic stress, impact and other mechanical actions throughout its lifespan. It is thus recommended to use solid materials with adequate compressive strength and flexibility.

Different Types of Flat Roofs

Flat roofs vary according to factors like slope and functionality. Flat roofs are not completely flat but they have a very subtle slope of less than 5°. Some of them are designed for higher traffic, others for lower traffic, so they can have slightly different structures.

There are several types of materials used for flat roofs and they must provide good sealing and protection against water infiltrations. Traditionally, flat roofs used to be covered with a mixture of concrete and gravel. However, this option is not very durable because this type of asphalt becomes fragile over time and surface cracks will appear eventually. In addition to not providing long-term protection against moisture, this material is not considered sustainable, because during production and installation, there are chemicals released into the atmosphere.
