Why use Manthorpe tile & slate vents?

Roof tile and slate ventilators are needed to facilitate essential airflow into properties but should do so without spoiling their kerbside appeal. Thankfully, Manthorpe's wide range of in-line roof vents fit in aesthetically as well as mechanically, ensuring a stylish and functional finishing touch to any project.  All our vents can provide roof space ventilation as well as an outlet for mechanical extraction if required for many roof types, pitches and styles of covering.

Roof tile vents are available in multiple colours and sizes and in all major styles such as Roman, castellated, pantile, plain, flat and thin leading edge, so you can be sure of finding the right vent for all your projects. Our slate ventilators can be used with both natural and man-made slates and are available in a range of sizes. 




Our roof tile and slate vents have undergone vigorous wind tunnel and driving rain testing at the Building Research Establishment (BRE) to strengthen the design features of the final products and ensure their compatibility with surrounding roof structures.

As part of the Genuit Group plc quality is managed throughout every aspect of our business and ISO 9001 accreditation demonstrates our commitment to quality and continuous improvement.
