These factors influence the price
- Roof area & pitch: Steeper roofs (> 45°) incur higher safety/access costs.
- Roof material: Concrete tiles, clay tiles and fibre cement require different methods.
- Degree of soiling: Heavy moss and lichen growth increases time and cleaning product requirements.
- Accessibility: Tight plots in Dortmund's Kreuzviertel or Nordstadt may require a crane or cherry picker.
- Additional services: Impregnation, coating or gutter cleaning.
When is roof cleaning worthwhile?
In the Ruhr area, fine particulate matter, mild winters and high humidity encourage the growth of moss, algae and lichen. Roof cleaning is worthwhile when:
- moss deposits are clogging the gutters,
- lichen is drawing moisture into the tiles,
- the property's appearance is suffering (relevant before a sale),
- a solar panel installation is planned.
3 practical money-saving tips
- Combine services: Roof cleaning + gutter cleaning in one appointment saves set-up costs.
- Neighbourhood offers: When several houses on the same street book together, travel and set-up time is reduced.
- Clean early: The heavier the growth, the more expensive the cleaning becomes.
