I have some cladding over the top half of my house. I want to run some co-ax through a point in the middle of the cladding. I either need to (a) remove the tiles or (b) drill through them.

tried removing the nails to remove the tiles, but the nails won't come out. Is there a proper way of removing these tiles? A proper tool?
Is it possible to drill through these tiles? They are synthetic, but don't feel like concrete. Even if I could drill through them, I have no idea what is underneath, e.g. a membrane, bricks, who knows?
If anyone could provide some guidance I'd be grateful.
They look like Marley Eternit slates / cladding - about 3mm thick. If so, they're easily drilled using ordinary HSS bits. The rest of the roofing structure should be conventional felt on battens.
The nails might be copper and should come out like any other nail but you might crack the slate around the nail. A direct pull would be best rather than levering them out.
Good point. To explain more, the co-ax is coming from the ground floor, not from the roof. It's a communal aerial system that I am splitting on my side (I've already tested the split, which gives satisfactory results).
I think I would remove a slate by cutting the nails followed by drilling the hole for the cable. Then replace the slate with different securing holes unless you can drive new nails in the same holes at an angle.
The "nails" to which you refer (I presume you mean the bits sticking out at the bottom of each slate) are actually not the nails at all, but clips that stop the bottom lifting. The "head" of the clip is trapped under the edges of the tiles beneath the one with the end of the clip protruding. These can be freed simply by unbending the shaft. However that will not release the slate, since that will be nailed higher up, where you cant get at them! Easy enough to slate from scratch - but harder to remove individual slates later.
To free a slate you will need a tool called a slater's rip. e.g:

slide up behind the slate and allow you to cut the nails holding the slate.
The problem with those is that once freed you will not be able to nail the slate back again in the same way, and will instead need to buy or make a slate hook/clip to replace it. (often done with a strip of lead nailed to a tile batten and laying under the replacement slate, with the end turned up to hold the slate in place.
It depends when they were installed, I think asbestos was still being used as a fibre in slates in the 60s, I still think he should be carefull just in case. Google for advice and at the least wear a particle mask when drilling Dan. Don
1) Remove the tiles, tough work
2) Drill through the tiles: chance of death in twenty years, plus I would need to get a new ladder I think
I'm just wondering... I know it's frowned on generally, but in my situation would others try going through a PVC window frame instead? It is another option. I would keep well away from the glass of course, it would be in the 'frame' part of the window.
