Every aspect of a home is important thus, it is important to decide carefully when roofing in Sydney because you have many options but the most common one is whether to choose tin or tiles. According to Chris Edgar, a member of the Master Builders Association of South Australia, there are advantages and disadvantages to the two materials.
When it comes to versatility, the steel is leading but looking at the lifespan of the material, tile is the clear winner aside from the fact that it is better in insulating sound and it has heritage appeal.
Mr. Edgar said that lightweight steels are ideal for architectural buildings because it can be formed into curves while the recommended pitch of tile is only from 18 to 22 degrees. Variance can be achieved when steel is used.
The only issue is that there is a big difference in the weight. Roof made of terracotta can be very heavy. The tiles can be as heavy as 60 kilograms for every square meter while steel only weighs five kilograms for every square meter.
Mr. Edgar said that flat roofs cost less to install but there might be problems in the future it the plumbing, wiring or the air conditioning system has to be changed. Flat roof is beautiful and it is possible but it has to be maintained more than the pitched roof because blockage can occur.
It is recommended to have at least two degrees of pitch because the curl on the edge can help in preventing the rain from coming back if it does not have enough run-off speed to begin with. On the other hand, roofs with higher pitch are more flexible.
Both tin and tiles can incorporate solar panels but the radiant heat can have an impact the panels. Tiles made of terracotta or concrete has the ability to absorb heat and as soon as the temperature drops, it sends it back out. Steel, on the other hand, lets heat pass through which is why the ceiling space can heat up a lot faster but dissipation is also quite fast.
For homeowners planning to do roofing in Sydney, make sure that you choose steel if your house is located in an area where bushfire is common.
