Why It’s Important to Have a Well-Ventilated Attic

Interstate Roofing

Often, people save on the roof ventilation, ignoring its importance and efficiency. A roof that is not properly ventilated has the following risks:

  • Condensation
  • Mold formation
  • Increasing humidity
  • Insect attacks

All these risks can cause severe damage to the wooden parts and to the entire roof structure. In order to understand the importance of adequate ventilation, we analyzed what is happening with a ventilated and a non-ventilated roof, during the hot and cold seasons:

In the hot season

Non-ventilated roof: The roof coat transmits the heat to the insulating material, which has a thermally slowing function. Subsequently, the heat is transferred to the interior of the building. As a result, more energy will be used for air conditioning.

Ventilated roof: The sun heats the air in the ventilation space, which becomes easier and goes out through the ridge, instead of accumulating under the roof.

In the cold season:

Non-ventilated roof: Due to cold weather and temperature fluctuations, condensation happens and causes mold and high humidity the roof`s structure.

Ventilated roof: In winter, air circulation will dry the insulation and avoid condensation. In the case of snow and frost, ventilation allows uniform snow melting on the roof and prevents the formation of ice barriers.
