Typically most roofs can be cleaned in 1-2 days however it does depend on the size of the property along with ease of access around the property. A driving factor that will affect how long the roof clean will take is the weather. In windy conditions above 17mph we cannot use our mobile access towers to abide by PASMA regulations, if it is raining or below 5c then we cannot apply the biocide treatment so we will have to reschedule to another day and lastly if there is forecasted lightening we must cease cleaning and reschedule as our poles are made of carbon fibre, this being a very good conductor of electricity.
