Over the years, your metal or concrete roofing will be subjected to contamination along the lines of dirt, mould, moss and lichen.
These stains compromise the appearance of your house. Bird droppings and mould spores can have an effect on the health of the home mostly for those who rely on rainwater tanks. These are important factors for carrying out high pressure cleaning on roofing.
Additionally, if your roof is being restored or repaired, high pressure cleaning is critical to set the foundation for an successful and long lasting finish.
