How is roof ventilation ensured?

How is roof ventilation ensured? Roof ventilation is an important part of a building’s functionality and durability. Good ventilation helps remove moisture and heat from under the roof, which can prevent mold and rot damage. Roof ventilation can be ensured in several different ways:

• Installing the underlayment: The underlayment is an important part of the roof structure, and it can be used to ensure roof ventilation. The underlay prevents moisture from entering the roof structures and enables air to circulate under the roof.
• Sufficient ventilation openings: A sufficient number of ventilation openings must be installed in the roof so that air can circulate freely under the roof. The ventilation openings can be located, for example, in the eaves, ridge or flaps.
• Ventilation pipes: If the slope of the roof or other factors prevent the free circulation of air, ventilation pipes can be installed under the roof. The ventilation pipes help the air to move and remove moisture effectively.

It is important to ensure that the ventilation of the roofs is properly implemented so that the structure of the roof remains healthy and durable. More information on the meaning and implementation of roof ventilation can be found, for example, on Rakennustieto‘s pages.
