Metal Roof Staining

[Ryan Bazeley]

Hi,

 

I have just had an Aluminium Standing Seamed roof installed which is finished in Anthracite colour. There were footprints all over the roof as it was muddy / wet on-site when being installed. I decided I would wash them off and what I have found is the footprints have ingrained into the powder coat finish leaving faint white marks? Is there anything I can use to remove this or can they not be removed?

 

Thanks.

You could try buffing them out with car polish ... t-cut or better still a similar colour colour-cut etc. 

They should have been laying boards down for standing on.

The anthracite coating is incredibly thin, perhaps 80 microns, and should not be reduced.

There is no underlayer as with a car, and you are straight to the aluminium.

 

Soapy water and gentle use of a soft cloth is the only option.

Otherwise let the weather do the job, with cold rain in the winter, and warmth in the summer it is likely to come off in time.

The roof will get dirty too, so it should become invisible.

 

If you only have dirt you are lucky, as gritty feet scuffing can make a right mess of a roof sheet.

It still should not have happened as cladders should know to either keep feet clean or use walking boards.

If the muck is grit then it may be pushed right through to the metal, and you can ask the roofers what they are going to do.

 

What do you think the marks are made of? Is it soil/ cement dust/ grit?

I may have some more suggestions if you know.
