Cleaning The Roof Tips

Cleaning the roof is often seen as the most cumbersome part of the entire house washing activity. Cleaning the roof is considered as a tough proposition by most, primarily due to the difficulty in accessing it. Thus, when undertaking the arduous task of house washing, roof cleaning is an activity that is often postponed for a later time.

As a result of this neglect at the time of periodic house washing, the roof develops a lot of dirt and becomes greasy, which is difficult to treat. At such times, you need to solicit the services of professional cleaners in order to clean the roof. However, given the large extent of dirt and grease on the roof, getting it cleaned by professional cleaning companies becomes a costly proposition. Regular cleaning of the roof will avoid getting into such situations.

One of the difficulties that crops up when cleaning the roof is the water and cleaning solution draining off into the garden and ruining your plants. Thus, while cleaning the roof, utmost care has to be taken to control the run-offs from the cleaning area.


Black staining is another area of concern when it comes to cleaning the roof at the time of house washing. The stains make the roof surface greasy and difficult to tread on. On such occasions, high pressure cleaning is the most appropriate solution. The black stains are a result of the growth of algae and fungus spores on the roof surface. In order to address this problem, you need to use certain cleaning solutions that specialize in removing such fungal growth. These cleaning solutions when coupled with high pressure jets of heat regulated water are extremely effective in roof cleaning.


Cleaning your roof utilizing the high pressure cleaning technique, a water pressure range of 1000psi to 1800psi is advisable. The higher the pressure, the more effective will be the cleaning process. However, care should be taken to ensure that the roof does not get damaged due to excess water pressure. The ideal pressure setting of the pressure water – the equipment used for high pressure cleaning – can be determined by enquiring with the roof manufacturer. In the case of metal roofs, the water pressure can be maintained towards the higher end of the pressure range mentioned above, while in the case of clay tiled roofs, it will be towards the lower end of that band. In the case of wood shingle roofs however, a pressure lower than 1000psi may have to be maintained to avoid damage to the roof.



Roofs often have crevices and those hard to reach places where a lot of dirt often gets accumulated. These areas get neglected during regular house washing stints due to the large amount of time and effort required to reach them. In order to clean these areas, extension wands must be used. These wands are thinner than the normal pressure cleaning hose. As a result, the wands enable focused thinner jets of water and cleaning solution under high pressure to be directed towards the target area. Extension wands also help in reducing the amount of water and cleaning solution required to clean the roof, thus resulting in significant cost savings.
