Which is better: tiles or long run Colorsteel?
This is a question we are frequently asked, and the truth is: it depends on your unique situation! We would recommend tile roofing to the home-owner who is looking for an easy-care, low maintenance, long-lasting roofing option – whereas long run can be slightly less expensive, you have a wider range of colour options, and there are a number of profile options to suit all tastes. There a number of pros and cons to each roofing choice, so the best policy is to talk with us first!
I have lichen and moss growing on my tile roof – is that okay? Or do I need to clean it?
In some climates, moss and lichen can grow in your tiles – this will not affect your tiles in any way, and in some cases can even add character! If you’re not a fan of the green, organic look however, growth on tile roofs is easily removed with a suitable cleaning agent – contact us for more information.
Will the colour of my concrete tile roof change? Would terracotta tiles fade too?
You may experience colour change. During manufacture, a coloured pigmented oxide coating is applied on the surface of the wet concrete tile in the form of slurry, fusing it to the surface. The concrete tiles are then painted with a water-based paint technology, which helps to alleviate the colour change process, however a normal fading process will still occur due to our harsh UV environment. Terracotta tiles, on the other hand, will NEVER fade, and will NEVER change colour.
I have longrun Colorsteel roofing; do I need to clean it?
With a durable, baked-on paint finish, Colorsteel resists chipping, peeling and cracking, is non-combustible, termite resistant, weather tight and secure – but it may require manual washing every 3 to 12 months, depending on the paint system, to prevent accumulation of dirt, debris or other material not removed by rain water.
Is my roof still under warranty if I don’t follow a regular maintenance schedule?
This is a very good question! The answer is most likely NO! You need to be aware of your warranty conditions when having a new roof installed, as regular maintenance is often mandatory. We can tell you everything you need to know about warranty conditions – contact us [link to contact] for more information.
Is there a waterproof coating on my concrete tile roof?
No, concrete tiles have no waterproof coating; they rely on the density of the tile to waterproof the roof. Grey, uncoated natural concrete tiles would perform equally as well.
I have noticed a whitish discolouration in some places on my concrete tile roof; is this normal?
Yes – and it will eventually fade. This is called efflorescence or ‘bloom’, and is caused by the natural salts in the concrete migrating to the surface. This has no effect on the tile’s performance.
I have a terracotta tile roof and am considering painting it – would that affect my roof?
Yes! You must never paint a terracotta tiled roof. Not only would the paint peel quickly, but if it is glazed it would become unsightly very quickly indeed! If you have a concrete tiled roof on the other hand, you can go ahead and re-colour the tiles whenever you like – however you should be aware that this is totally an aesthetic choice, as no concrete tiles produced in the last 40 years require repainting to maintain their performance. If you are unsure as to the age of your roof, contact us.
Which roofing is best for thermal protection?
Both concrete and terracotta tile roofing offer great thermal protection due to their density – however it is a little known fact that tile roofing also offer the very best protection against radiant heat from bush fires!
