How to choose a Roof

Choosing a roof is one of the most important steps in designing a new home.

Your roof will be seen by more people every day than your new home theatre. It will represent five per cent of the value of your home, and contribute far more than five per cent of the comfort of your home in extreme weather conditions.

Your roof will have an effect on every day you spend in your house and it will significantly contribute or detract from your re-sale value when you move.

Decisions about your roof are far too important to leave with someone else.

Fortunately, once you know the facts, choosing a roof is simple. You need to consider:

  1. What the roof is made of.
  2. What shape or “profile” the roof is.
  3. What colour and finish your roof will have.
  4. How long your roof will last.


Until now, the traditional choices for roofs were Terracotta or Concrete. And, while these materials have various benefits, the biggest benefit they have is that they are heavy. Because traditional roofs do not have structural joined between tiles, the traditional tiles need to be heavy, or they will blow away.

With the Tractile Interlocking Roof System (TIRS), this is no longer the case.

This means you can take advantage of more modern and specialized materials.

Tractile tiles can be cheaper to make and cheaper to install. You can add high-tech insulation at the rear of the tile itself. On the outside, you can explore a new world of colours and finishes.

With the Tractile system, you can add the Tractile Solar BIPV-T technology. You could contain your entire solar hot water system not on your roof and inside your roof, but within your roof.

The only downside is that before where you have a choice of two, now you have a conundrum of millions. But we think that’s a nice puzzle to have.


Leaving aside freak storm conditions, the main battle fought by traditional tiles against the weather is that of stopping water penetrating the roof. In most cases, heavy terracotta or concrete tiles perform this task admirably; except when it comes to stopping water flowing down the roof from being blown up between the tiles.

Traditional tiles need a steep roof angle (pitch or rake) to hasten the flow of water due to gravity and therefore to limit the chance the water has to blow up between the tiles and into the roof.

Roofs built utilizing the Tractile Interlocking Building System do not have this problem because the connection between tiles acts as a barrier to any wind assisted water incursion.

The wind and water challenge limits the shallowness of the roof angle of a traditional roof and can force a home builder or owner to use channels or sarking to limit the ingress of water.

With the Tractile System, stopping water getting in under tiles is no longer a problem. The pitch of a Tractile roof and the shape of the tiles is now completely a matter of looks and taste.

And with modern materials and innovation, that’s really the way it should be.

Like the look

Your roof goes on top of your house. With a Tractile roof, that’s the only rule. With almost no limit on roof angle (Tractile roofs can be as shallow as 5 degrees and include sections at 90 degrees), the only constraints your have are the laws of physics and geometry, and your own imagination.

Match your roof to your walls. Match your roof to your fence. Match it to the natural surroundings of your home. Mix and match colours, textures and materials with only one consideration: what you want your roof to look like.

Built to Last

Because Tractile tiles are created in one process, with all materials forming part of a single mould, the life of your roof is the life of the materials.
