Garage roof leaks!
Discussion
Having just bought my first house, I was looking forward to getting my car away in the garage, but it leaks!
It's got a corrugated concrete roof that appears to have a few cracks in it, letting water in. How can I repair this? During heavy rain, you could see it dripping into the garage, and in a few places too.
Any suggestions would be greatly appreciated

New roof, if it's as bad as you say.
BUT be careful as those Corrugated roof's you speak of sound more like Double 6 (asbestos content) roofing sheets.
For a quick fix try a roll of flash band, also try warming the sticky bitumen side with a small blow torch for better stick-down-ability.
Good luck

Best to replace cracked/split sheets but; there are brush/trowel-on products (ask at local builders merchant) that can be used to repair said leaks. Do not stand on the roof, as there is no give in the sheets. One moment you will be standing on them, the next, you will be through them and wondering just what has happened. Best use a scaffold board placed over where the rafters/joists are supporting said sheets.
As above, flashing (of the metal kind, not exposing yourself...) should sort it. Put it over the joins in the roof (I assume they are overlayed on top of one another, similar to tiling?).
The corrugated roofing is generally the asbestos type stuff as mentioned, so if you take it down, be careful and know where you are going to get rid of it before you remove it.
Other than flashing, you can pick up bitumen paint from B&Q for a few quid and spread it over any visible leaking areas. I's only use that as a temporary fix though, it won't look too pretty, but it'll stop it leaking for the moment.

Best to cure the Prob once and for all time, remove the Concrete/asbestos sheets, and replace with box profile Steel roofing sheets, these are cheap as chips and easy to fit yourself. Whilst you at it why not replace one with a translucent sheet and give yourself some daylight in the garage too
I've got the same roof with the same problem. Didn't want to get on top for the risk of falling through. Bought some roof sealant in a tube, like bath mastic. Just ran it along the crack on inside and smoothed down with finger, has bodged the job beautifully until I can be arsed/afford to get it done properly!
Right, I spent 5 hours slappingon bitumen roof sealant, which hasn't done a lot at all really, so I have another plan. Im not going to be in a position to replace the roof this year (having just bought the property as our first), so, could I make up a new roof from corrugated PVC plastic, lay this ontop of the old roof, and fix it to the wooden battons around the edge of the old roof? Could this work, as it would divert the water to the back of the roof where it doesn't leak?

You could, certainly, but you would be as well by fixing battens (laths) across the roof, above the existing cross-battens, then fix the sheets to them. If you just fix around the edge, the wind will get under the sheets and rip them off.TBH, if you're thinking of over-boarding (which is what this is), you'll find it easier to just remove the old, knackered sheets, then fix the new PVC sheets to the cross-battens. Be aware that the PVC sheets come in three different thicknesses, 0.7mm, 1.1mm and 1.3mm. The sheds (B&Q, Wickes, etc) stock the 0.7mm thickness, which will probably need extra cross-battens to support it. For the little extra that it will costs, I'd go for the 1.1mm.
