Product Description


The Metrotile LV75 roof space vent is designed to provide an integrated outlet for the passive release of moisture-laden air from the roof space. When used in conjunction with venting at the eaves, it creates a simple in/out airflow pattern to adequately ventilate the roof space. In many parts of Europe (with similar temperature variations to New Zealand), this type of venting is mandatory for the removal of moisture created inside all residential homes (from cooking, bathrooms, heating etc). In New Zealand it is fast becoming recognised that increasingly air-tight construction methods are allowing less of the natural moisture created in our homes to be released. This moisture laden air often ends up in the roof space where it can condense on the roof.



Ventilation is a big topic these days when it comes to roof spaces or in-house ventilation. Modern houses become increasingly more insulated and air-tight, however, with cold and humid weather conditions like in New Zealand, house owners may still experience water dripping from the exhaust cooker or other outlet vents from bathrooms or laundry room. These conditions can create serious moisture problems with attendant damage and health issues caused by mould and damp.

The Metrotile Vent is part of the High-Performance Roofing System. The unique design of our roofing system means there is no penetration cut on the roof and no need for ancillary trades to get up on the roof after the roofer has completed the install. It requires no further flashing, and is installed by a qualified roofer who is trained to install the weather-tight roofing system.
