I have a problem with my roof tiles. Who should I contact?
In the first instance, you should contact the installer/supplier of the roof tiles to report the issue. For ongoing matters of complaint, contact the relevant Fair Trading Office in your state.
Do we need a different frame for terracotta or concrete?
The spacing of trusses (the planks of wood the tiles sit on) will need to change based on the tile being installed. Concrete tiles are a standard size so the set out will be the same however many terracotta tiles come in varied sizes and therefore require unique truss set outs to accommodate and support the tiles they hold.
What is the best roofing solution for coastal conditions?
Concrete or terracotta roof tiles are ideal for coastal regions as most products are suitable for marine environments and their high salt content. In the absence of rain, metal roofing requires frequent hosing down in high salt concentration areas, which can pose difficulties with water restrictions.
Is a dark roof any hotter in warmer months?
This will depend on the finish applied to the roof and paint used. In many cases research does suggest that a dark roof could attract heat, however, this has not been conclusively proven and other factors such as house orientation, use of ventilation/insulation and use of passive design principles will have a greater bearing on whether the house is hotter in the warmer months.
What is roof sarking?
Sarking is an impermeable reflective foil membrane that is laid under tiles and acts as a secondary barrier to water run off while reducing the amount of heat transferred in and out of the house by acting as a reflective barrier. Sarking reflects as much as 95% of radiant heat away from the home, ensuring more comfortable living conditions. The cost will vary based on the builder used and level of sarking product chosen.
What is flexible pointing?
Flexible pointing is a flexible and extremely durable coating that is applied to the bedding used to fix ridge fittings to the roof. It does not crack with the natural expansion and contraction of the roof because of its flexible properties. This pointing system significantly reduces the need for pointing maintenance. It is available in a wide range of colours that allow it to be matched to all standard tile colours.
Will the colour of my tile give me any advantages or disadvantages (light or dark)?
Dark coloured tiles are generally perceived to absorb more heat while light coloured tiles reflect more heat. This factor is a parameter used in BASIX and NatHERS rating schemes. However, heat absorption and reflectance only partially contribute to a roof’s energy performance. With simple inclusions such as sarking, insulation and ventilation dark tiles are shown to perform just as well as light tiles.
How should I choose roof tiles to minimise my power bills?
Factors such as thermal mass, tile thickness, colour, profile, pitch and R-values all contribute to your tile’s thermal performance. According to BASIX and NatHERS rating schemes, if insulation or ventilation are included, these inclusions will make some of the other factors, such as colour, negligible. Currently, further research is being conducted to explore these factors in depth.
How expensive is it to re-roof?
