Fair enough Darren I see you’re point what do you do them from a lift or roofing ladder.


The vast majority of that job could be done from the ground.

I do a few roof jobs on an annual basis and would use a scaffold tower on that job to ensure it’s all done to the required standard.

Do you just jet them or do  you apply a product first or after.

This is what I use, a little different to Darren who jets them I believe.





I also now use a turbo nozzle to tidy up stubborn lichen on roofs.

Always biocide after - if not the moss etc will be back inside 18 months

Slacky - is that the exact one you use ? what size is it

Yes it is. It’s the size of a large frying pan.

Of course it depends how badly soiled the surface is but I’d expect to get across that roof in your pics in a day quite easily with that. And clean out the gutters/fascias etc after before the end of the day.


Turn the uploader valve down with one of these otherwise she’ll fly…

I don't want one for roof cleaning - I'm looking for a good 12" ( like the Mrs  ;D ) for plastic decking - I do approx 120 decks in a holiday park and the FSC works like a charm but they are 15" and a bit bulky so a more compact jobbie is just the thing - any chance of a link ?

if not now when you return home
Thanks

One of 3 cleans this week

Nice job Darran

When you pressure wash a roof do you always use high heat and low pressure?

Cold

We reduce pressure down 150 Bar

Do you reserve using heat for just particularly bad/ filthy jobs regardless of the type of surface?

I use heat when the job calls for it like brick cleaning (low pressure high temp) graffiti removal - gum removal

I've yet to find cold struggle with standard type pressure watering no matter how dirty it is

Try using a long length lance at more than 150 psi,  it's hard work!

Goes everywhere,

2 meter is fine - that’s why we use access machine to avoid things like long lances

Thanks for all the info guys, lots of comments and advice on there, much appreciated.
I think the scraper is out for me as it looks proper tedious. Pressure washing better option no dou,bt but i think only on certain jobs where you can gain access via a cherry picker or spider lift, as Darren said (dont want to be clambering on top of roofs for sure). Might leave it alone for now!!
Darren, do you have your own spider lift or hire one, what sort of cost to hire? and do you need a licence?

I have considered buying but one machine does not fit all - we have sometimes only needed 12 meter m/c others the old genie 80/60

Generally I use Hinowa 20 for most domestic work which runs £190 per day - most roofs are done in a day

I have seen this done with the scraping method and it looks very hard work saw some guys using Darren’s method the whole house was done from a spider lift in a day,it didn’t look like he was using a jet wash though more like sand blasting.

there was a guy around here that sand blasted them (about 16 years ago) but I don't think he made a go of it - veery messy and that did damage tiles
