Tiled Roof Cleaning

Majority of people are unaware of the importance of having their roof cleaned. Have you ever looked at your roof and wondered why there were green/black tinges on your roof.  These are often forms of mould and lichen moss. And the only signs of problems occuring could be if the occupants begin to have persistant headaches, nausea and respiratory problems etc. Mouldly buildings are known to present sometimes serious health risks to its occupants.

The quality of water that is captured by your roof can also be a problem. By simply cleaning the tiles of your roof may increase the street appeal and value of your house.

And finally, the moss or lichen can block the water channels on the joints of the tiles.  This can cause water to enter your roof space and create leaks.

Now most companies believe it is good enough to wash a roof with cold water.  We have never understood this.  Nobody that we have ever talked to would attempt to wash their dishes or clothes with cold water and expect them to be clean afterwards. 

So we have invested in custom made boiler systems that allow us to clean your roof with “steam” (well not quite, but the water is very, very hot).  This ensures that we get rid of ALL the dirt and residue off your roof.  No matter if it is sap, bird droppings or just general grime in the pores of your tiles, you can be assured that your roof is not only cleaned to the highests standard, but also kills the associated bacteria and ensures that your drinking water is safe (provided yor tank is not contaminated).

Tiled Roof Restoration or Replacement

There are many reasons to consider a roof restoration.

The roof is leaking and not economical to repair.
The roof is not functioning correctly.
The roof tiles let in too much dust and is too hot.
The roof does not look good.
You are extending and want a uniform look.

Whatever your reasons, we know enough about all the various options that we can work something out to suit your needs.

Why consider the change to colorbond roof?

Colorbond is a brand name of a coated steel product produced by Bluescope Lysaght. This product is essentially strips (coils) of high strength steel that has been coated with zincalume and then upgraded with factory applied paint on both sides and a final finish coat on one side.

For many commercial roofs, the unpainted zincalume roofing sheets are used. This is because of economy. A roof with colorbond material will look better and will outlast a zincalume one. Colorbond is the choice for most homeowners because there is not a big cost difference to get to pick your colour to match the rest of the house and to have it last longer.

Colorbond roofs in the different profiles has taken the imagination of homeowners and architects looking for a difference. It is lightweight. It can be used in more situations than the traditional tiled roof and the look is very modern. For flat roofs the use of metal roof sheets is the only viable roofing option. So why not upgrade to a colorbond flat roof. It can be used in pitches from 1 degree to 90 degrees and can offer better thermal qualities with the effective use of insulation directly under the roof sheets. This insulation also has the benefit of reducing the noise of raindrops – although most people do not notice this noise as being obtrusive.
More people are choosing to get rid of the dull boring tiled roof and replacing it with a colorbond one.

We get many queries about the advantages of colorbond roofs over tiled roofs. While both types of roofing material have their merits, we have been replacing many tiled roofs with colorbond mainly because the tiled roofs leak. A combination of trees dropping leaves and debris onto the tiled roofs and a low pitch of 25 degrees and less is a recipe for ongoing leakage problems that only a colorbond roof can solve.

Use zincalume on your gutters…and you will end up replacing them well before the roof. This is wasting money!

How long will my roof last?

Bluescope Lysaght guarantees their colorbond for 25 years. CSR has a 50 year warranty on their concrete and terracotta tiles. In reality, we have seen roofs of lower specifications last much longer than those time periods.

Built properly, a roof usually spans almost a lifetime.
But then, we have seen roofs last only as long as it takes for the next storm to arrive!

The serviceability and durability of the roof depends on how the materials are put together. That is why the manufacturer’s warranties always state that their products must be installed to their specifications in order for their material warranty to be valid.

The secret to a long lasting roof? Get it done by the roofing professionals.

We often get asked:  Is a tiled roof better than a steel roof?

Well there are at least 3 different issues to consider:

1) From the structure point of view:
According to the Australian Bureau of Statistic, the average house size today is 264m2.  This means, after allowing for pitch and eaves, a tiled house roof with weigh 15.6 tons (excluding any timberwork), while the same roof in steel would weeigh merely 1,467kg – i.e. less than 10% of the tiled house roof’s weight.

Although the roof structure is designed to carry this kind of weight, its will be affected by the constant weight and the structural members will gradually deform over the years.  This is often evident at the gutter corners with regularly start to hold water after a few years, due to the hips being elongated.

2) From the utility point of view:
Tile companies claim that the additional weight of a tiled house roof makes storm damage less likely.  But, we think the big hailstorm that hit Sydney on 14 April 1999 hs dispelled this myth.  In fact, the lighter weight of a steel roof is absolutely not a concern as long as the house is properly constructed and tied down according to the Australian Standard.  On the contrary, steel house roofs are regularly used in cyclone areas!

3)From the security point of view:
A young mother of three, Judith, ‘broke’ into her own home through the tiled roof without using any tools when she left her keys accidently inside and locked herself out.

If Judith managed to ‘break’ into her own home easily, could you imagine how easy a ‘professional’ burglar can get into her house (or any house) through a tiled roof?
