I have a flat roof that is a little "long in the tooth"

I thought I would give it a coat of paint to see if I could stall the
inevitable [one or two sunken its hold water].

I haven't used the paint before but iI get the impression it is both
very fluid and very volatile.

I want to keep my activities on the roof to a minimum, so I suppose
spraying the stuff on would be best.
Lidl do a sprayer for £14-00 has anyone any suggestions/ experience?


The paints instructions warn against use on polystyrene, so I would
guess that it may melt certain plastics. Also if the paint is
flammable might there be a risk of a static discharge using a sprayer.

Any suggestions would be welcome.

If you wish to extend the life of a felted flat roof somewhat, use a
product designed for the purpose like Aquapol. But it is far too thick to
spray without sophisticated equipment. But easy enough to brush on.

I don't know what the material is, it was smooth silver finished when
first fitted and had a sheen that I wouldn't associate with felt.

Whoever fitted it warned of the need to keep painting it with an
aluminum paint. I do not know what the paint was and I suspect that
the roofing company is no longer around.

Is the main ingredient that is detrimental to the "bitumen"?? based
coating likely to be sunlight?

I did a search on Aquapol, but the cost seems to suggest that it may
be best to hang on until the leaks start, then worry about a new roof.
