Clay Ridge Tiles - fixing

[PAFCBOY]

Lost a clay ridge tile in the storms. One close to gable end. This was a weighty beast 46cm long 90 degree red clay tile on a 1930's house with slate roof. That was some gale. I have sourced a replacement from a reclaimers.

I've not been up there yet - I'm having to invest in a long ladder - but it looks as if there are a couple lumps of cement remaining in situe on top of ridge. No cement came down attached to the tile so I imagine the old fixing material is still up there.

Any advice on preparing the roof (in terms of old cement) before fixing please. What do I fix replacement ridge tile with and how? I've read 3:1 sharp sand mix but won't it just slide down the roof!? Do I fix then point. How much do I use to fix - a bed under each flap, a couple of spots on ridge itself? Do I leave time between fixing and pointing? Does it need to be dry for a few days before/after fixing? I'm probably over worrying on what is a simple job!

Just get a roofer to do it? It needs bedding on mortar and can be pointed straight away.

Or use magic goo instead of mortar http://www.fleximroofputty.com/- not tried it myself yet but seen a demo & it looks excellent, will be giving it a go when I get to that stage

I have never heard of the stuff has anybody used it ?

If anyone on here has used it I'd be very interested to hear how they got on- it looks perfect for my application (200 year old house with skinny rafters = a certain amount of movement on the roof. Mortar fillets and ridge tile bedding looked very neat but they'd all cracked due to movement so roof was leaking at key points)- bit pricey (£40 for 5m x 100mm so probably £80 for both sides and joins in a 10m ridge at 30 degree pitch ish) but I'll only be doing it once.
I've refelted and rebattened and currently reslating using the Marley Eternits that were installed badly about 20 years ago- eaves and ridge detail were all wrong, lap was down to 60mm in places, random galvanised nails (20mm to 60mm) used everywhere instead of copper/ally. Pics to follow- its starting to look half decent!

Its handy to keep in the van for emergency repairs, and working in wet weather, but far to pricey, you will use loads on the joints.
I was in roofing yard this morning and they can hardly shift the stuff.

Back bed the ridge on, with some clips screwed down if your in a windy area.
