an average conny roof takes me an hour to clean,set up and move on to my next job.this includes cleaning all the windows on the property if its a 3-4 bedder(maintenance cleans)with no access issues.
if its pretty dirty i spray with tfr or virosol in a 5l pressure sprayer and wfp off on custies outside tap if available.i usually charge between £40-£60 and then the price of the windows on top of that price.good little earners!!
