Suited to Marley Wessex roofs, this tile vent adds clean, effective ventilation at high or low level. The face matches the covering profile so from street level the elevation reads coherent, and the internal geometry promotes generous free area to move air through the roof space. A vent cap helps prevent debris and pests from entering, keeping performance steady. Installation follows established practice and results in a detail that looks intentional rather than improvised. Choose the Wessex tile vent to reduce condensation risk, support insulation and maintain a calm silhouette across the roof.
