Why Is Roof Ventilation Essential?

Poor air circulation under the roof can lead to costly structural damage and mould-related health problems. Proper ventilation ensures :

Prevents the build-up of moisture that leads to mould.

Reduces excessive heat under the roof in summer, reducing the need for air conditioning.

Prolongs the life of shingles and insulation materials.

Allows more efficient heating and cooling.

Prevents the formation of ice in winter, which can lead to water infiltration.

How Does Roof Ventilation Work?

Good ventilation balances the intake of fresh air with the removal of warm, humid air. Choosing the right system depends on your roof configuration and local climatic conditions:

Based on natural air movement via soffits and openings under the roof.

Using fans to extract warm, humid air.

Integration of ventilation grilles at the ends of the roof to promote circulation.

Strategically placed at the top of the roof for efficient air flow.

A Ventilated Roof, a House That Lasts

A well-ventilated roof protects your home from the harmful effects of humidity and temperature variations. By evacuating warm air and preventing condensation, an efficient ventilation system extends the life of your roof, improves your comfort and reduces your energy bills.
