Roof Ventilation

Importance of Roof Ventilation


The roof ventilation not only affects your roof, but also the heating and cooling system of the entire house. During the cold season, the roofing helps to release all of the heat collected in the attic. In winter, the heat accumulated in the attic is dangerous because snow and ice on the roof melt prematurely and an ice dam is created. In warm weather, poor roof ventilation can store heat in the attic and seriously affect your cooling system, reducing the energy efficiency of your home. Proper roof ventilation is important to give off excess heat in the attic and to protect the roof and air conditioning system.

Another danger of poor roof ventilation is the accumulation of water. If there is not enough escape method, trapped water can seriously damage the roof substructure. Moisture over time can cause mold, mildew, nail rust or even cracks, and the roof terrace is also prone to rotting. Adequate ventilation provides an escape route for heat and moisture and prevents these costly disasters.

Roofing is important in hot and cold weather. Ice dams on the roof can damage shingles and sinks. The hot air condensing in the attic promotes the growth of mold and mildew. In hot climates, inadequate ventilation can lead to premature wear of the asphalt shingle roofs and invalidate the material guarantees of most manufacturers. This can also cause the clay and concrete tile roof cushions to fail.

Operations of Roof Ventilation

The system that enables air circulation consists of air inlets and outlets that are installed at intervals in the attic or in the roof area. The right design and structure of the ventilation system are important. The roof structure should provide sufficient air space to ensure insulation and air circulation under the roof and eaves. In addition, a properly designed system precisely balances the inlet and outlet ventilation under the roof, so that the attic is slightly pressurized, which prevents the conditioned air from being sucked in too quickly through the ventilation holes, which increases heating and cooling.

Appropriate roof ventilation

Ventilation holes built into the wall and added to the roof allow some air to flow naturally, but may not be enough to promote the airflow required to maintain a constant, more moderate temperature. The turbine and vents that contain the fan can be set to automatically open during the hottest hours of the day or to be opened manually using a switch in the house or garage. Improving roof ventilation can reduce utility costs and extend the life of the roof.

Inlet and outlet

To ensure proper airflow, you need a method of drawing cold air into the attic (inlet) and a method of venting hot air (outlet). The continuous movement of the air inlet and outlet of the outlet are the keys to maintaining a pleasant atmosphere in the attic. This can also improve air quality and reduce the number of mold spores and other microorganisms that try to live in your home. The use of vents and wind turbines can significantly improve inlet and outlet efficiency to create a positive and even airflow.

Even airflow

Wind can create a stream of air in your attic, but it is not even. To make the continuously flowing airflow even, you need to apply an external force. In most cases, wind turbines, ventilation slots, roof fans or ventilation slots for the power supply can provide the airflow that is required to maintain a constant temperature and to maintain the highest possible air quality. Stable airflow also prevents the accumulation of moisture. Too much water promotes mold growth and actually increases the rate of rust.

Advantages of proper roof ventilation

Extend the life of the roof

Extreme weather can affect your roof in many ways that we cannot see. If the temperature is too high, the temperature on the roof doubles, heating the house. Poorly ventilated roofs and inadequate exhaust openings can lead to heat build-up, which can damage the inner and outer shingles. However, if the roof is well ventilated, warm air can escape and keep the roof and the room cool.

Lower your electricity bill

The roof is well ventilated and your air conditioner doesn’t have to carry all the load to keep your home cool and comfortable. When the roof air inlet and outlet holes are properly installed, warm air can be easily extracted, while cool air can easily enter your home. The logic is that operating fewer air conditioners uses less energy, thereby reducing electricity costs.
