Why Clean Your Roof?

A new roof or re-roof is probably an expense most homeowners would prefer not to think about. So it makes sense to properly maintain the one you already have and extend its lifespan. Indeed, there are many particularly good reasons why you should keep up with roof maintenance. Some of which you may not be aware of.

Firstly, a roof, covered in green moss and lichen or black algae, ruins the appearance of a house. This may well detract from its market value. You can decorate the exterior of your home and spend a fortune on your grounds. Although it will never really look like the part of the roof is unsightly, contact Powerdrive.

Roof Cleaning Perth – About Moss and Lichen

This moss and lichen also degrade the terracotta roof tiles. This can also aid in the process of a structural defect known as chemical delignification.

Real estate agents will recommend a roof cleaning Perth when a property is put on the market. After all, kerb appeal and first impressions count. The longer you leave the job the more difficult it will become and the more it is likely to cost.

Secondly, there are several reasons why you should look at roof cleaning in Perth. Moss and lichen can spread quickly and stealthily, depending on the local conditions. Tree shade, humidity, and position in relation to the sun.

Although the lichen and moss do not actually attack roof tiles themselves. They can hold water against the surface and create an environment. That leads to the roofing material becoming more porous and, hence, more susceptible to rain erosion over time.

More About Moss

The porosity also makes your roof frame structure more likely to develop chemical delignification. Therefore instead of just having a small problem of an unsightly roof, that can be fixed with roof cleaning, you now have a potential major structural defect.

One of the main problems with moss is that it can accumulate in the various water channels on the roof. This can lead to poor drainage and overflowing gutters. The outcome of this is often water running down the walls of your home. Which again can lead to a whole new set of potentially expensive problems.

The mould growth also prevents the reflective quality of a roof and can lead to higher heating and cooling bills.

Roof Cleaning Perth procedure

Roof cleaning Perth is done in three main stages. Firstly generally involves a treatment using a special, biodegradable sterilising solution or roof ripper.
Lichen is spread when its spores are transferred to the roof by the wind or birds landing on them.

Simply washing the growth off with water could fail to remove these tiny spores. They embed themselves in roof materials such as terracotta roof tiles made from natural clay. Therefore, more porous than most other types of roof construction.

The Powerdrive roofing roof cleaning solution effectively kills these spores and inhibits any future growth. It’s environmentally friendly, and will not harm your pets or damage the exterior of your home.

The second stage involves pressure cleaning, carried out with maximum care using specialised equipment.

There is a fine line between eradicating the lichen and causing damage due to over-saturation. Or damaging roof tiles by allowing large amounts of water to force its way beneath the roof tiles.

Our tradesmen are well-trained and experienced and know precisely how much pressure a roof can withstand. They know how to work on a roof without damaging it during the roof cleaning process.

The third and final stage consists of rinsing down the roof and surrounding areas to remove excess chemicals. Sweeping up any debris, and clearing disturbed moss and lichen. Cleaning any gutters and downpipes impacted by the roof cleaning process.

Can you Prevent Your Roof Getting Dirty?

Do trees that cast a shadow on your roof? It is a good idea to have them trimmed or even thinned. Lichen and moss find it almost impossible to grow in bright sunlight.

Tempted to clean the roof yourself. Be aware this is a hazardous task for the amateur. Wet roofs are extremely slippery and potentially highly hazardous. But there is also a particularly good chance you will break tiles. If you have not been trained how to walk correctly on a roof.

Risks of Roof Cleaning

Are you living in Perth? Is your homes roof covered in lichen? (moss). In many cases a high pressure cleaning Perth service can be all that old, the tired roof needs to restore it to its former glory. No roof painting is required especially if you have terracotta roof tiles.

Although if you are working with terracotta roof tiles that are covered in lichen, I would recommend you first check the roof structure prior to roof cleaning. This combination is often related to chemical delignification. Chemical delignification starts with efflorescence from the roof tile. This salt is then leached into the roof structure.

Once started it the delignification process will begin in the first structural member the tile is in contact with. Roof tile battens are a structural element that takes the load of the roof tiles and evenly distribute the weight. Chemical delignification will continue to spread if left untreated.

Structure is in Tact

If the roof structure is in good condition, we can get back to the roof cleaning, again depending on the tile type there are different options for pressure cleaning Perth, there is hot water high pressure cleaning Perth and the old faithful cold water.

Some companies will push towards hot water pressure cleaning saying it kills the spores and has a much deeper clean. The truth is on terracotta tiles hot water can actually do more damage, it makes the tiles more brittle and removes a lot more of the natural surface of the clay, in turn making them more porous and susceptible to lichen attack in the future.

Once we begin the high-pressure cleaning procedure, we make sure to get all the roof tiles washing from the ridge capping to the gutter line. Make sure to get the front edge of every tile on the way down. It is important when roof cleaning Perth not to push water into the roof void and cause damage. Angles are everything.

Time For The Roof Ripper

When the roof cleaning Perth is completed, we then apply a product called roof ripper, (or similar). This is what will break down any spores that are left behind without causing any further damage to your roof tiles. The last thing you want is to have to do a roof replacement because an inexperienced high pressure cleaning Perth company has broken down your roof and or roof carpentry.

We talked earlier about checking the carpentry but we haven’t yet mentioned the roof inspection prior to starting the roof cleaning Perth process.  It is very important to check any places that there could be a risk of water ingress.

Then there is always the chance of flooding the roof. Remember, you are not insured if anything goes wrong and you are doing it yourself.
