Many houses in the UK have moss on their roofs. Moss damages roofs. But how do you remove it without causing damage to the roof?

The old solution is to get the roof pressure washed, however this is bad.

Homeowners fear pressure washing for 4 main reasons:

  1. It damages the tiles, taking the protective surface off it.
  2. Often causes water damage inside the house – and can be very costly to the homeowner.
  3. Causes a lot of muddy mess.
  4. People on the roof break tiles, often not informing the customer which leads to costly problems some months later.


Our ‘Reach and Blow®’ System uses compressed air from an industrial petrol air compressor mounted in a van or trailer. The air hose is on a portable reel so you pull it out to where you are working on the property.

  1. The ‘Reach and Blow®’ System leaves the top protective surface of the tile intact.
  2. Using the ‘Reach and Blow®’ System causes no damage to roof tiles or very delicate surfaces because it uses compressed air combined with lightweight attachments.
  3. The ‘Reach and Blow®’ System is a ‘dry’ no wet mess system.
  4. Accessing the roof from the gutter level means that no one goes on the roof – this is what sells the roof clean service to many customers.

How it works

The method of working is mostly off a portable scaffold which gives a stable platform to access the roof tiles from gutter height with the ‘Reach and Blow®’ System. The scaffold is gradually moved around the house as you clean the roof.

The choice of which attachment to use depends on the type of moss and tile – currently there are 4 brush attachments and 9 metal scraper attachments which come in the standard System. This means you can clean concrete, clay, slate and man made tiles as well as the different profiles that these tiles come in.

Having chosen your attachment, you get to work, loosening the moss and blowing out the dirt lying in the tile joints. The compressed air is powerful enough to blow the dirt and moss out of the tile gaps, but does not damage the tiles. Once loose the moss and dirt are then blown down the roof. A tarpaulin is placed underneath the scaffold and the dry mess is simply wrapped up in the tarpaulin and disposed of.

In this way you can clean the roof with superb results without going on the roof and causing no distress to the homeowner.

Having cleaned the roof you can apply biocide to the tiles to leave the whole surface incredibly clean and any moss roots eradicated.

The ‘Reach and Blow®’ System is the perfect partner for clearing moss off roofs prior to Softwashing.
