Common Roof Types

Galvanised Iron

Corrugated, galvanised iron sheets are the most common form of roof covering found in Queensland.

Decramastic Tiles

As possibly one of the most disliked roofing materials in existence, Decramastic roof tiles are pressed metal tile strips that were made to imitate concrete tiles. Produced from light gauge metal, it deforms very easily if walked on – often leading to roof leaks.


Also known as fibro, super six, asbestos cement or AC sheeting, the hazards of this once popular construction material is well documented.

Concrete or Terracotta Tiles

Concrete or Terracotta roof tiles are hung from the framework of a roof by fixing them with nails. The tiles are usually hung in parallel rows, with each row overlapping the row below it to exclude rainwater and to cover the nails that hold the row below. There are also roof tiles for special positions, particularly where the planes of the several pitches meet. They include ridge, hip and valley tiles. These can either be bedded and pointed in cement mortar or mechanically fixed.

The team at Vantage Point did an excellent job replacing approximately 2000m2 of 80s era galvanised roofing with Trimdek sheets and Wonderglas skylight panels. Great communication and workmanship from Will and team team. Would thoroughly recommend to any commercial property manager/owner.


I was pleasantly surprised by the level of customer service, professionalism and the quality of installation that the team had provided. The multiple persons I dealt with over the phone including the installation team were friendly, attentive to my needs/questions and I felt they were more than capable of delivering the final product.


For those looking for an honest, reliable roofing installer that provide top quality workmanship, efficient same day friendly service, starting from roof quoting to inspection, through to faultless completion of a new roof, I highly recommend Vantage Point Roofing. I am a grateful customer.
