Product Description


The sanitary vent provides a means to release sewage gases to the exterior of the structure or outdoors through the roof. The flow of air is the primary consideration in the design of a sanitary venting system for discharge from sanitary fixtures or appliances. The most significant benefit of our vent is that it is entirely integrated into the roofing system, meaning complete weather-tightness peace of mind.



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 are 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.
