MYTH 1:
“Concrete and Terracotta Tiles are Porous”
False. Tiles are manufactured to NZ standard 4206:1992 and are tested for permeability and water absorption. During manufacturing, tested tiles are required to hold 50mm of water for a period of 24 hours without leaking. In water absorption testing, the standard also requires that tiles do not absorb more than 10 per cent of their own weight in water.
MYTH 2: “Concrete and Terracotta Roof Tiles Crack Easily”
False. Building products can break when handled incorrectly, but the reality is that concrete tiles should not crack if you walk on them in the correct place. Concrete gets stronger with age and concrete tiles are no exception. Care must be taken when walking on metal sheeting, as it is susceptible to denting when incorrectly walked on. Dented metal can result in a costly and difficult job to replace the whole sheet of damaged metal whereas in the unlikely case of broken tiles, it is extremely easy to replace individual tiles.
Myth 3: “ALL ROOFS GET HOT EASILY AND OVERHEAT YOUR HOME”
False. Concrete and Terracotta tiles have a larger thermal mass. Tiles take longer to heat up or cool down.
This minimises sudden temperature changes, improves air circulation AND prevents condensation that might occur with metal roofing.
With the use of insulation they provide superior thermal properties for a warmer, drier and more comfortable home keeping your family safe and warm.
MYTH 4: “Metal roofs suit all New Zealand conditions”
False. Not all metal sheeting will be suitable for the range of environmental conditions we see in New Zealand. Being an island nation, you will need to prevent your metal roof from rusting and corroding and it may require a significant amount of maintenance to protect it and comply to warranty terms.
- Metal roofs covered with ColorCote® are recommended to be washed with fresh water every six months in those areas not normally exposed to rain*
- Every six months you need to check fasteners, fixtures and fittings for corrosion and keep the roof free of lichen, leaves, pollen*
- Holes and penetrations in your metal roof can expose the substrate and let in moisture, therefore care needs to be taken every time you make a hole in any ColorCote® product to ensure that you don’t void your warranty.
- Exposed fasteners may increase potential for damage to internal structural supports. Concrete and terracotta tiles, on the other hand, don’t rust or corrode, and the colour of a terracotta roof tile will last for the life of the tile.
