Manthorpe Castellated In-Line Roof Tile Vent

The Manthorpe Castellated In-Line Roof Tile Vent offers a discreet and effective way to ventilate your roof space or terminate a soil pipe or extractor fan through a square-profile tiled roof. Designed to blend seamlessly with the surrounding tiles, this in-line vent replaces a single tile to maintain an unbroken, low-profile roofline—ideal for both high and low-level ventilation on pitched roofs.

With a built-in 4mm louvred grille and internal water management system, this vent achieves a consistent 10,000mm² airflow while preventing rain ingress. It's suitable for pitched roof ventilation down to a 20° pitch and can be used in conjunction with mechanical extraction ducting or for soil stack termination through roof tiles.

Available in four colour options, it suits square-profile tiles such as Marley Ludlow Major, Redland Renown (with modification), Sandtoft Lindum, Russell Cheviot, and Lagan Square, offering broad compatibility across major roofing brands.

Whether you’re installing a new roof or upgrading an existing one, this vent provides a low-profile ventilation solution that performs without compromising aesthetics.
