on the bottom row of my roof the tiles are falling down 2 or them,have lifted the tiles and can find no holes to fix nail to wood on roof and no lug at top of the tile to hook over wood on roof?

Just as easy to get a couple of new tiles for about 50p each.
Take a faulty tile to builders merchants or even better to a roofing contractors to get the correct make & size (they have loads leftover from jobs and glad to sell for a few quid!)
You wont get an exact match due to weathering over time etc. but if the colour is very different put the new one where it cant be seen (behind a chimney or back of house) then put the weathered one in its place so it looks just as good.

There are two ways I used to fix then especially half tile when the lugs were missing.
1. Lead strap the length of the tile + 75mm to form the hook on front end bend it over the end of the tile then fold half down over the strap this helps to stop it uncurling. Nail top end to tile batten using galvanized nail.

2. With a masonry drill and drill Not set on hammer drill nail hole in centre top end to line up with batten nail it on the other tiles either side will stop it twisting. I do same with slate eves tiles when the slip out.
