How to fix bitumen corrugated to concrete purlins?

[ScottishGasMan]

Nearly done removing the asbestos cladding from the garage roof. However as the right angles bolts that hold it round the purlins are old and seized I've had to cut them off from inside (thinking it would be no bother to get them) however it appears none of the roofing places or ironmongery shops can get me them.

So are there any other options for fixing the roof to the beams? Its bitumen cladding I've bought.

You are going to have to buy more timber to support the sheets because they are too soft and will sag, so you may as well get some lengths of 4x2" and then you can use normal fixings.
