At what distance from the ridge is the aerator placed?

In the world of architecture and construction, every detail has its own meaning, and the roof is no exception. When designing a roof, special attention is paid not only to aesthetics, but also to functional aspects such as ventilation.


♦ An important component of effective roof ventilation are aerators. They not only help maintain optimal temperature and humidity indoors, but also extend the life of roofing materials.

♦ One of the key issues when designing a roof is the optimal location of aerators. This aspect often determines the efficiency of the ventilation system. Design specialists are often faced with the question: at what distance from the ridge should aerators be installed?

♦ It is considered the most optimal to place aerators in the roof ridges at a distance of 6-8 meters. This allows for uniform ventilation over the entire roof area. In addition, aerators should be placed at the highest points along the valley, where the funnel lines meet. This additionally ensures effective removal of excess moisture and prevents the formation of condensation.

♦ When it comes to flat roofs built on cement-sand screeds using materials such as roofing felt or PVC film, it is recommended to install at least one aerator per 100 square meters of area. This provides enough ventilation to prevent moisture buildup and maintain the integrity of the roofing materials.

Choosing the right type of aerator also plays an important role. Lattice, turbine or vent aerators may be optimal depending on your specific roofing conditions. It is also important to take into account the climatic characteristics of the region where the building is located in order to adapt the ventilation system to specific requirements.


Roof design is a complex process that requires the integration of various elements. The placement of aerators is only one of many aspects, but undoubtedly one of the important ones. By ensuring proper ventilation, the roof designer creates not only functional, but also durable protection for the building.
