The importance of ventilation between the roof

Written by Posted On Friday, 11 January 2019 02:55

There are several elements that help to prove the effectiveness of good roof ventilation. Without good ventilation through the roof, it would be impossible to effectively control the airflow in the roof.

Having good roof ventilation means avoiding a lot of long-term problems.


The benefits of good roof ventilation

In addition to the fact that poor ventilation between roofs will contribute to the rapid deterioration of your roof, problems such as overheating in summer and the accumulation of water vapor causing mold will also be there. A well-ventilated roof will suffer less ice build-up along the overhang of the roof.

By having good ventilation between roof, you can keep yourself away from lots of issues.

In summary, good roof ventilation will provide the following benefits

  • Protect the roof system against the accumulation of water vapor
  • Maintain the quality of your roofing
  • Keep a pleasant climate in the building
  • Avoid inflated electricity bills due to heat loss
  • Maintain the durability of your roof and your building

A good ventilation system for a flat roof

Although roof ventilation is easier for a sloped roof than a flat roof, it still requires a good ventilation system.

In the presence of a flat roof or with a roof which is difficult to access, the positioning of the ventilation must be strategic. We suggest dividing the area evenly and then installing fans in the center of each of these divisions. The number of fans depends on your requirements and varies according to the manufacturer's requirements.

Good ventilation between roofs will help maintain the quality of your roof system and save you a lot of hassle.


A good ventilation system for a sloping roof

Generally easier to access than the other roofs; sloping roofs favor the installation of a good ventilation system.

The best way to control airflow in a sloped roof is to suck the air through perforated soffits or to install ventilation grilles at the bottom of the slopes of the roof.

The location of your vents should provide a good vent, both horizontally and vertically to minimize moisture accumulation.


If my roof liner is waterproof, do I really need good roof ventilation?

Even if your roof is 100% waterproof, it is still important to have good ventilation between roof. A waterproof roof significantly reduces the moisture problems of the roof, but a minimum of ventilation is still necessary.

A waterproof roof does not control the air inlets and outlets in the way that good ventilation does. To avoid future repair, it is important to consider the installation of a good ventilation system.
