hi ya
had gypses canvasing for roof cleaning on my manor, i see one guy standing on a roof jet washing it no harnes or rope tied to him, they seem to get the work
........pete
Pete that was the point I was going to make with James.
James for costing in my experience, it all depends on how you carry out the cleaning and the quality of the clean / service offered. In general if they are slate tiles we will not clean due to their make up ie extremely thin / fragile. A previous post states around £20 sm that is a std coat manu guide price but would include treatment plus application of good quality coating, not just cleaning.
If you work as a 2 man team min one ground one roof, use professional equip (I know some companies which use Karcher washers and even take them up on to the roof!) work safety / ropes etc you can charge higher rates and beat the gypsies

providing a quality service - really depends how far you go for example our vac alone cost over £1600 which does not include poles.
no we would not prespray - quality wash will achieve desired results
