Is Roof Cleaning Safe

Is Roof Cleaning Safe?

Is roof cleaning safe for my roof type should be your first question to any roof cleaning company. It can often depend on how much moss you have allowed to grow on your roof. When left too long and moss has colonised all over your roof tiles it may be too late.

Moss covered tiles could have roof problems underneath and you should ask, Is roof cleaning safe for my roof. When the moss has gone under the tiles and into the roof joists it may cause leaks when removed.

Mosses, lichens, moulds and fungus are natures way of decomposing materials back into the earth over time. The process begins quickly and certain roof tiles may fail quicker than others, for example fibre cement roof tiles are covered in a thin membrane of colour, acids secreted from organic matter quickly eat through this to get to the limestone cement they crave underneath. Is roof cleaning safe for fibre cement roof tiles all depends on the levels of infestation on them, and of course we need to ask how long have they been on the tiles.

Roof Tile Types

Most other roof tile types in the United Kingdom will be affected over longer periods of time and therefore is roof cleaning safe for these types, yes in most cases they will look almost as good as new when cleaned by a professional roof cleaning company.

Methods of roof cleaning;

  1. Brushing off Moss
  2. Scraping off Moss
  3. Low Pressure Water Spraying
  4. Soft Washing
  5. Drone Spraying (in the future)
