What to use to waterproof metal shed roof?

[DIYNotIan]

Hi all

I am planning to help someone make their metal shed watertight as it seems to let in a reasonable amount of water from the roof.

It's a shed like one of these:



Could we use felt? If so, what type would be best? We know nothing about felt and so don't know where to start with all the different options! I've checked out some felt adhesives and they say that they will stick felt to metal.

Aside from felt, are there any other options we should be considering? Needs to be affordable....

Many thanks

Max

Is it leaking, or is it condensation on the inside? If it's leaking then you need to identify where the leaks are coming from and seal them. If it's condensation, which steel sheet is prone to, then you need insulation of some sort inside.

MKM's Evercryl......paint on thickly, reinforced with glass fibre.
The roof must be in a hell of a state though?
