How Roof Vents Prevent Condensation

Posted: by & filed under Roofing

Ventilation of the attic is an essential element for the roof’s good performance in the long term and avoids condensation problems. Besides that, roof vents regulate the temperature in your home. On the other hand, poor roof ventilation can lead to condensation, further resulting in mould growth due to the accumulation of snow and water vapor or overheating in summer.

Here’s our explanation of the importance so that you can ensure they’re in perfect condition this season!

Negative Effects of Condensation

Condensation is a significant issue due to the lack of ventilation, leading to mould growth. A case of mould in the attic will spread mould spores invisible to the naked eye in healthy sections of the attic. These spores will subsequently become sporangia which, in turn, will develop new spores as a contamination effect. Homeowners often overlook roof vents without realizing the consequences of condensation when, in fact, they are an inexpensive way to reduce such risks.

Is Condensation Normal to Have?

Condensation in the attic is not an uncommon issue facing homeowners. In fact, it’s a widespread issue. Below are some of the common signs of condensation:

Dampness in attic

Water damage on the roof layer

Water accumulation in roof tiles

Mould growth

Musty smell in the attic

How Roof Vents Help with Condensation

Roof vents regulate the temperature of the attic. The air stays fresh, the climate remains moderate, and intense temperatures cannot get inside, reducing condensation.

It is also imperative to ventilate the attic, especially during the summer season, as this prevents overheating problems. In addition, the temperature of the shingles can climb up to 60°C or more. For an asphalt roof, this is not ideal.

This heat trapped in the attic then heats the underside of the roof and your roof shingles. It is, therefore, essential to let the heat out through the suction effect of the roof ventilator. In addition, overheating the shingle also reduces its lifespan. Maintaining fresh air in your attic is synonymous with good attic ventilation.

A well-ventilated roof lasts longer, does not deteriorate quickly, and is not invaded by mold due to the accumulation of water vapor. Plus, by ensuring good attic ventilation, you won’t have to spend money on situations you could have avoided.

Thus, installing roof vents is an essential element of a roof design since they ensure the ventilation of the roofs and prevent the formation of condensation and premature wear of the roofing materials.
