What Are Roof Vents?

Roof vents are purpose-built components installed on rooftops to regulate airflow within the roof space or loft area. They allow fresh air in while expelling stale, moist air, reducing condensation, mould growth, and structural damage. Available in various styles (e.g. tile vents, ridge vents, over-fascia, and cowls), they are essential for maintaining a healthy, energy-efficient home.

Types of Roof Vents

Vent Pipe Terminals

Available in PVC and Bitumen, these are essential for ventilating pipe systems protruding through the roof. They help in maintaining airflow and preventing moisture buildup.

Breather Vents

These come in PVC, EPDM, and Bitumen. Breather vents are crucial for allowing air to circulate under the roof, reducing the risk of condensation and improving the overall health of your roof structure.

Universal Vent Tiles

 Including both cap-only and base with cap options, these vents integrate seamlessly with your roof tiles, providing efficient ventilation while maintaining the aesthetic appeal of your roof.

Rainwater Outlet Vents
