How do venting outlets and chimneys fit onto a concrete roof?
All bathrooms require venting onto the roof and this is usually in the form of a black or white PVC pipe that protrudes out of the roof in the middle of a piece of aluminium foil used for flashing. This is unsightly and often leads to leaks. Gambale has special tiles that will accommodate a venting pipe as an integral part of the roof in an elegant PVC or concrete chimney.
