Blast Away specialise in roof cleaning restoration removing all unsightly moss, algae, lichen and general stubborn airborn pollution.


Each roof is different, from the type of tiles to the type of organic growth. From these factors we know if the roof should either be pressure washed or soft washed.

The Roof Cleaning Process
  Stage one

  All health and safety set up is undertaken, downpipes disconnected to prevent drains becoming blocked and any flower bedding and lawns covered with sheeting.

  Stage Two
  The roof cleaning process is started. If your roof is mossy, we will ensure your neighbours are aware there may be a possiblity of moss balls being blasted over into their property, so they will be reassured that we will clean up any mess.

  Stage Three

  A qualified and well experiened roofer will undertake the following if needed;
  • Replace all broken roof tiles
  • Re-point ridges, hips, valleys and eaves
  • Inspect and repair lead work


Stage Four

We then apply an anti-fungicidal wash onto roof tiles using a backpack low pressure spray.

This treatment will remove any moss and lichen spores to prevent and minimise re-growth.





How much does it cost to jet wash a roof?

We charge from £350. As each roof is different from it's size, difficulty and the extent of the moss to be removed, we can only accurately price your roof from either a visit or by images.


Does jet washing damage roof tiles?

Experience and the correct equipment from a professional roof cleaner will result in no damage to your roof.

However, roof tiles can be damaged by inexperienced operatives. Correct methods need to be used in accordance with the right pressure, the right water flow rate and types of lance nozzles. Inexperienced roof cleaners or those just starting out may use either too much pressure, the wrong nozzle or even go too close to the tiles with the lance.


Pressure Washing Damages Shingle Felt Roof Tiles.

In many American states the properties are made up of mainly shingle felt roof tiles.

These shingles are cleaned by low pressure and chemicals known as soft washing.

There is a misconception on the web between the UK and US about pressure washing damaging roof tiles which often is referred to shingles in the US and not concrete tiles.


Do I need a new roof?

Simply the presence of algae stains and moss does not necessarily mean you need a new roof.

In many cases all a roof needs is a good professional clean to restore its original look and colour. You might notice that many roofers and roofing companies don't like roof cleaners, why do you think this is? A roofer wants your money for a new roof that really may just needs a good old clean.

If a roofer tells you that it's time for a new roof just because it's caked in moss and/or algae staining tell him to get back in his van and go away, give us a call and you'll save thousands of pounds!
