Replacing Garage Roof

[ScottishGasMan]

Hey all, going to be replacing a garage roof as soon as posible and looking to get all the materials together for when the weather is better.

Is a sectional concrete garage, pre cast panels with nuts and bolts holding it together,

looks like cement fibre corrugated roof held to concrete beams run along the top of the garage,

Im looking to do it the cheapest way that will work, so was thinking I could just get some bitumenr corrugaded roofing, and replace whats there,

the sheets at the moment appear to be held to the concrete beams but l shaped bolts, can anyone advise me where to get some of these fixings incase the ones that are there are rotten/need cut out?

meant to say, ive seen lots of L-bolts on searching, but these have a little extra bend and the end of the L so they hook round the beam
