you can either pressure wash it for him or just brush it. Either way give it a spray over with some algicide. It'll kill the moss.

I think you may need scaffolding(legally)

We cleaned about 900m2 on a store last month.

We used a small electric platform, extending lances - with turbo nozzles fitted and two 15lpm pressure washers.

The roof came up like new.

We then had to clean all the guttering out, upvc and soffitts because we made a right mess. Total job - couple of days.

The roof had damaged tiles but it became clear that the kids who sat in the park - next door, would throw stones up and see how many they could break (all the stones were in the gutter).

This is the second large roof I have cleaned and H & S would not allow me to 'sit on the peak'.

None of our activities damaged the roof tiles.

I do have photos and they will be appearing on our website, when we next update it.

If I were you I would get a scaffold tower, pressure washer, extendable lance and all the other bits and bobs required, clean your dads bungalow roof for free, or a small price and then you can take your photos at every stage.

You will have cleaned one, got the photos and know what to expect and how long it will take, if you get asked to clean any more.

A small bungalow roof should not take any more than a day. just check that what is underneath the tiles is sound and is not going to allow water to ingress into the loft space!!!

Just me, BUT the day rain comes down at 250bar is the day I'll start washing roofs

These men doing wash and seal/recolurs are selling to marley tiled homes on the principle that marley only guarantee the tiles for 30 years so they are targetting houses about 30 years old, then PERSSURE WASHING the end of its life tiles!!!

And they only give a 10 year guarantee on the seled job. I wonder what the service in like on guarantee call backs during next 10 years? Watch this space ehh

Because a roof aint designed to take 250 bar. If you use a turbo on a 250 bar machine the pressure is well in exess of that.
You got flashings vents and such, plus you can bet yer last £ that any damage after you finish "wasn't there before"

AND roofwasher dont sound right as I,m a drivewasher lol.............

Is that an opinion from experience or supposition?

I can tell from experience that you are wrong.

We were called in to tidy a roof on a store in Whitstable, last year. A contractor had attempted to clean it and had left it patchy and half done. We cleaned it properly and the end result was more than satisfactory, with no damage.

The store that we have recently cleaned the roof on in Hayes - Middlesex has had a £50million  refurbishment and extension. Part of our work remit was to make the old store roof tie in with the brand new extension.

The roof is there for anyone to go and have a look at and the store and the site agents were staggered by the end result. Again - no damage.

These contracts are so valuable that if I thought that we were causing damage to any surface we woud review our working practises and lower pressures and remove turbo nozzles.

This year I have cleaned thousands upon thousands of metres of elevated and ground level surfaces for Sainsburys and they would be less than happy if we continued to damage such large surfaces.

Good luck

Rob ;D

Theres a big difference between a slate roof and insulation laminated steel cladding, I would'nt be over keen on cleaning a slate roof but I would a factory. I did my flat roofs with fibreglass and when I get a quiet spell I will pressure wash them - every job is different and should be treated as such, you can't say I won't do this or that because that may be the lead that opens an avenue to a lot of work and if others have turned it away may well be lucrative. Also it can be difficult to adhere to the safety rules all the time ie securely attaching ones boot lace to a ridge tile >:( >:( >:(
