How to make roof ventilation

The operation of any building requires the provision of necessary measures aimed at extending the life of all structural elements. In this respect, the roof is no exception. For any type of roof, sufficient ventilation is necessary to increase the lifetime of its roof. If this is not done, then condensate from moist air masses will be absorbed into the insulation and structural elements made of wood. This can result in the destruction of the roof. You should know for sure how to make roof ventilation to ensure proper airflow in the attic space.

Relevance of ventilation

Device roofing ventilation

Condensate accumulated under the roof in wintertime can lead to the formation of ice and cause various damage to the drainage system.

Note! If there is insufficient air circulation in the heat, excessive heating of the roof may occur, which will cause an undesirable temperature increase throughout the building.

Ensuring adequate roof ventilation in a private home is the only effective way to get rid of the excess moisture that accumulates under it. Properly arranged air ventilation will ensure the removal of unwanted condensate that comes from the interior of the building. The presence of normal temperature and humidity under the roofing cake will ensure the preservation of the insulating properties of the roof insulation, prevent deformation of the roof structure, and also prevent the processes of decay.

Types of ventilation

Ventilation cold attic

Modern roofing technology involves the installation of several basic types of ventilation. The first option involves the provision of air circulation in the attic space, in case the roof is not insulated. At the same time the roof is equipped with only one waterproofing layer. The second option provides for a layer of insulation in the roofing pie. In this case, ventilation should ensure the circulation of air masses between the insulation, waterproofing layer and roofing material.

Another way to ensure the ventilation effect under the roof is the arrangement of the eaves circulation using perforated spotlights or embedded ventilation grids. In this case, the heater should not be used in the eaves space, as it will close the ventilation ducts. Today, to improve air circulation, roofing aerators, which are ventilation rolls or special tiles that have air ducts and insect screens, have become more common. They are usually set along the skates or on the pitched space. They do an excellent job, freely releasing air masses.

Flat roof aerator

For flat roofs, exhaust electric fans or turbines are provided, as well as special ventilation nozzles and ducts. The most common roof ventilation option is a dormer window. Such an element does an excellent job with its technical function, and can also greatly decorate the front of the house.

How to provide roof ventilation

Ridge

You need to know how to properly do the ventilation of the roof to prevent the above problems. In practice, the key to ensuring adequate roof ventilation is the creation of a ventilation gap between the roofing material and the waterproofing layer. Usually, an additional vertical bar is used for this, which raises the roofing material over the inner layers, providing free air flow from the eaves of the roof to its ridge. On the ridge of the roof, you can install a special aerator, which has many holes for the exit of air masses.

Roofing

If necessary, you can install point aerators, if the roof structure is too complicated. The principle of their operation is the same as that of the ridge aerator, therefore they are also effective for providing the necessary air circulation in the under-roof space. If the roof of the metal, for ventilation, you can use special fans and passages. They are installed by cutting out fragments of such a roof and mounting devices to ensure the necessary tightness.
