Roof Cleaning: Moss, Algae & Lichen Removal in Aberdeen
Roof cleaning services provided to remove moss, algae and debris from homes and businesses.
The correct cleaning method depends on the material, age and condition of the roof. Using excessive pressure or unsuitable equipment can damage protective surfaces, dislodge slates and tiles, and reduce the serviceable life of the covering. We assess the roof first and use a cleaning method suited to its construction and condition.
While carrying out the work, we also check for visible defects such as cracked, slipped or loose slates and tiles, reporting any concerns back to the customer.
Moss is more than a cosmetic issue
Moss, algae and lichen commonly develop on shaded roof slopes where moisture remains for longer. Although growth does not always mean the roof is damaged, a heavy build-up can retain moisture, obstruct drainage paths and make it more difficult to identify cracked, loose or deteriorating materials.
As moss breaks away, it can collect in gutters and outlets, restricting the flow of rainwater and causing overflowing. Regular inspection and appropriate cleaning can help maintain the roof covering, keep drainage systems clear and reveal defects that may otherwise go unnoticed.
Signs your roof may need cleaning
- Moss, algae or lichen across slates or tiles
- Thick moss growth along the lower edges of roof slopes
- Dark staining or streaks on the roof covering
- Moss debris collecting in gutters or around the property
- Noticeable discolouration of the roof
- Heavier growth on shaded areas or beneath overhanging trees
Moss collecting in the gutters can restrict rainwater flow and indicates that both the roof and drainage system may need attention.

Contact usHow long does it take?
It depends on the size of the roof, the pitch and how heavy the growth is. Smaller roofs are often done in a few hours. Larger or heavily covered roofs take substantially longer, and we would rather take the time than rush it.

How much better will my roof look?
Professional cleaning can make a striking difference by removing years of moss, algae, lichen and built-up dirt. It can restore much of the roof’s natural appearance and give the entire property a cleaner, brighter and better-maintained finish.
Results vary depending on the age and condition of the covering, but roof cleaning is often one of the most noticeable exterior improvements you can make.
How often should a roof be cleaned?
Most roofs benefit from a clean every two to five years.
Where you sit in that range depends on your roof. Overhanging trees, a north-facing slope and persistent damp all speed growth up considerably. A sheltered, sunny roof with nothing overhanging it can go a good deal longer between cleans.
Is roof cleaning safe for my roof?
Yes, provided the roof is assessed beforehand and the cleaning method is appropriate for its material, age and condition.
We select techniques suited to the individual roof, removing moss, algae, lichen and debris without using unnecessarily aggressive methods. If the covering is too fragile or deteriorated for cleaning, we will explain this and recommend the appropriate next steps.
