It was awesome to see you guys at the ASB Showgrounds! It was a great show for us to show case our products, especially the new Vent. The Metrotile Vent is part of the High Performance Roofing System. The unique design of our roofing system means 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.
