Hi guys,
 I know this is the window cleaning section, but lots of other topics discussed here and some very experienced guys, so thought i would ask.
Im now doing roof cleaning, but decided to go with the softer approach of scraping and then a biocide. I already have several customers lined up.
- How long should it take approx, to scrape a bungalow roof, pretty easy access, mostly covered in moss, but not horrendous. Size of roof is around 140m2 (approx time fellas) for two people, one scraping one getting rid of the moss
- Im looking at the biocide "Algo Clear Pro" it says 5 litres will cover 1025m2 (approx) obviously water it down to get that, just wondered what you guys think of that - seems to go a long way. Cost wise wouldnt be that much if it goes that far? £20 max for the roof, seems cheap?
Finally, im looking at the best options to apply the biocide (obviously using the correct PPE)
(Options - which is best or any of these)
- My current pressure washer, (petrol engine) with long reach pole and various nozzles?
- back pack, using waterfed pole and brush it on, or use end nozzle to spray on (not fine spray)
Any help on this appreciated, just so i can work out how much to charge based around time and biocide costs, i know people dont like to discuss prices on here, so not asking for that.
Thanks in advance guys.

Price - as with windows or gutter clearing what you charge is your choice

Roof work is a bespoke service and you should be making far more p/h than any other service.

I won't/don't scrape roofs - far to physical and long winded - then applying a chemical that takes weeks to show its worked - its not for me, altho there are those that do it that way

Read the general section - some good threads and photo's on there on results achieved etc..

Hi Darran,
Thanks for the reply.
Yes it is the physical/ labour intensive side that puts me off a bit, but there would be two of us, so would probably take turns! The other person moving all the stuff that comes off and hoovering it up/out of the gutters etc. We would generally use a small tower for access, so not just balancing off a ladder!.
I looked at the pressure washing side, as i have a petrol enginge pressure washer. It just bothers me a bit, having all that water/pressure on the roof (incase it causes water damage inside i suppose)! Plus not easy to reach with a pressure washer, i assume you would need a cherry picker type to get proper access to the roofs! I would imagine a lot more expensive for the customer for sure, due to all the equipment needed.
I will have a look at the general section, as mentioned.
Thanks again Darran, much appreciated.
