Ventilation is a process through which the air enters or leaves the roof by keeping the temperature of the house moderate. If the roof’s ventilation is not done properly, it will lead to many problems with the roof that reduce the roof’s life span. Therefore, ventilation is very important to balance the room’s temperature and keep the house’s roof safe from extreme weather conditions.

Venting is a process through which excess water is not allowed to enter the room. A vent is like a small hole in the roof that balances the air or moisture in the roof. The vent can be in any shape and size. Mostly the vent is located near the wall. The importance of roof ventilation cannot be neglected for moisture retention in the roof.

The ventilation can be done mechanically and naturally, depending on the requirements. The mechanical ventilation requires a power source attached to the roof for the proper intake and exhaust of the air. In natural ventilation, the natural processes like the stake effect and the wind effect work together for the natural ventilation.

Purpose of roof vents:

The roof vents are designed to keep the air level maintained inside the building. They have a cover opening that opens and closes according to the requirement. There is a spring load attached to the vent opening. The vents are made of plastic, metal, or fiberglass.

Over time, due to extreme weather conditions, the vents tear, and they might cause leakage. For example, the vents leak in areas with frequent heavy rainfall, and the water enters the roof.

A proper ventilation system can save the roof from excess moisture.

How does Roof ventilation save the roof from moisture?

The moisture can cause serious damage to the roofing if proper ventilation is not done. In addition, the moisture on the roof might result in the rusting process, mold, mildew, and many other problems that in result damage the roof’s structure.

When blown up in the environment, the hot air carries moisture with it; when this hot air is in contact with the air on the roof, it results in the condensation of the air. That results in water droplets or excess moisture on the roof. If the proper ventilation system is not installed, the moisture enters the roof.

A well-moisturized environment provides favorable conditions for the growth of unwanted pests.

Reason for excessive moisture in the buildings and houses

In recent years, buildings and houses have been designed to have proper tight air ceilings. No ventilation and proper insulation of the buildings do not allow the proper air intake and exhaust, resulting in poor air quality and excess water retention.

The best way to resolve this issue is to have roof ventilation so that the excess moisture built up from human activities like bathing, washing, etc., does not accumulate on the roof.

Best ways to remove excess moisture through ventilation:

Venting: Through venting, the airflow is balanced in the house, and the excess moisture is also removed. There is no excessive moisture in the building due to venting. Installing vents is a very technical task. You should never be compromised on the safety of your house. Always consult experienced technicians for the venting.

Insulation of the Roof: The roof’s insulation plays a very important role in keeping the roof dry and warm. The excessive moisture does not build up through insulation. Insulation does not allow the process of condensation to happen on the roof. Vapor retarders play an important role in keeping the moisture away.

The vapor retarders act as a barrier between your roof and the water. The vapor retarders do not allow excessive moisture to build upon the materials like wood. The vapor barriers are very common nowadays; you don’t require any excess roof renovation to install these barriers.

The vapor barriers can be installed on any old roof. However, you should consult your roof contractor to install the roof barriers. It will help you save money in the long run by keeping your roof damage-free.



With time, the moisture build-up on the roof can cause major structural damage to your roof if not addressed properly. In addition, the roof’s ventilation system should be maintained properly from time to time. The rusting and the mild growth among missing shingles are the few problems caused by the water retention on the roof.

A proper ventilation system can save your roof from a lot of issues.
