Roofline Tile Vents

Please see the relevant section for Cowl Vents, Economy Vents and Ridgeline Vents

Corovent Roofline Vents are discreet interlocking tile vents that are designed to blend seamlessly with the profile of the tile for an almost invisible appearance from the ground level. They come with several features, including a unique discrete cassette that always keeps water above the roofline. The vent has a round felt sleeve that reduces the risk of felt tearing around spigots, and a large spigot ensures excellent roof ventilation. Like Cowl Vents, there is an option for the vent to come with a pipe adaptor for connection to extractors. An inline roof tile vent is less visible on the roof line and has a ventilation area of 10,000mm Sq.

Roof Tile Vent Colour Matching

Ariel Plastics offers a roof vent colour and texture matching service that guarantees their products will blend seamlessly with the roof or building for a more aesthetically pleasing finish. Their colour matching service ensures that the Corovent will discreetly blend with existing tiles, even on a weathered roof. Additionally, the texture of the roof tile is matched to ensure a consistent look and feel. This service is useful for architects, roofing professionals, and homeowners who want high-quality products with a seamless finish.


How Do I Calculate the number of roof vents required?

Building Control specifies either High Level (Ridge) or Low Level (Eaves) airflow requirements for roofs, such as 5mm or 25mm continuous airflow. To determine how many vents to install and where to place them, we need to convert the "mm of airflow" to "number of vents" and "centres for roof vents." Check out our useful guide for further assistance.
