Road map: cleaning roofs

Step 1: Analysis roofing

First of all, the roof has to be inspected thoroughly. The cleaning depends on the roofing type and the nature of the pollution. A wrong cleaning agent or a too high water pressure could lead to permanent roof damage. It is therefore advisable to rely upon a professional firm in order to ensure a wonderful result.

 

Step 2: Cleaning the roof

When you want to clean a roof, you need to take into account the type of roofing:

  • Roof tiles get cleaned by means of hot water and a high-pressure cleaner. Dirt, moss and algae are washed away fluently because of the warmth and strength of the water. If the pollution is too persistent, an extra cleaning product is often used.
  • Also roofing sheets are cleaned in this way. They are very sturdy and stable, as a result of which the high-pressure cleaner is the perfect cleanser.
  • As a slate roof is more fragile, one lowers the water pressure a little. In doing so, damage to your house is avoided.
  • In case of a thatched roof, no water is involved. With this sort of roof, a thin layer of the roof is shaved off entirely. This way, the dirt, moss and algae disappear immediately.

 

Step 3: Finish and protect

After the cleaning, the roof is squirted with a disinfectant so the roof remains clean longer. Afterwards, you can still protect the roof by using roof coating. That means a protective layer is sprayed onto the roof. This layer is either transparant or in a colour of your choice. Thanks to this coating, your roof is much better protected and it will look like new for a longer time.
