Roof Cleaning and Washing
Over time, roof surfaces accumulate significant biological growth and general weathering debris. Moss, algae, lichen, and dark streaking caused by atmospheric pollution are all extremely common on Irish roofs, particularly in areas that see regular rainfall.
Left untreated, this growth does more than make a roof look neglected. It actively works against the performance and longevity of the tiles themselves. It will also need to have gutters that get regularly blocked, which can lead to water overflowing and penetration issues.
Celtic Clean and Seal carries out professional roof cleaning and washing for any type of domestic or commercial building.
Moss is probably the most visible offender on most roofs. It retains moisture against the tile surface and, during colder months, this trapped moisture freezes and expands, gradually breaking down the surface of the tile over repeated cycles.
Lichen is a slower-growing but more stubborn problem. It anchors itself directly into the tile material and, if left long enough, can cause permanent surface damage that no amount of cleaning will fully reverse.
Keeping a roof clear of this growth is a straightforward way to extend the working life of the tiles and maintain the property’s overall appearance. Give it an extra boost by getting your roof painted to give extra protection and a new colour!
Soft Washing vs Pressure Washing
Celtic Clean and Seal assesses each roof individually before deciding on the appropriate approach. Soft washing, which uses lower pressure combined with specialist biocidal treatments, is often the preferred method for older roof surfaces or tiles that require a more careful touch. The biocidal treatments do the heavy lifting by killing the root growth rather than simply removing what is visible on the surface.
Where pressure washing is appropriate, it is carried out at the correct settings for the tile type, ensuring an effective clean without causing unnecessary wear.
If moss, algae, or general discolouration has taken hold on a roof, professional cleaning is the most effective way to address it properly.
