Nailing every tile

[23vc]

Hi
It's a bit of a way off but I'm using Marley Anglia tiles on my extension roof, and I'm pretty sure every one is meant to be nailed down nowadays. Question is though, I'd far rather nail every 3rd row or something, to make it easier to get them off if needed (not sure why admittedly) but is that a complete no no? Not sure who I'd be falling foul of, doubt building inspector would know or care, guess it's house insurance void if it catastrophically blew off in a storm?
Anyway appreciate it's probably a silly question but does everyone really nail every one of these type of tile nowadays?
Cheers
John

Just nail every one, if you need to get one out then a flat bar will do
if you lift up the ones above.

Ok will do, thanks

Only reason to remove would normally be due to damage so removal should not be a consideration , only a matter of slipping a hacksaw blade under to cut of nail.

practice nowadays is to fix every tile, though to be honest there are loads of roofs still functioning fine which probably only have the first few courses nailed on the whole roof, if that.

Except the winds are getting greater, so maybe that's the new thinking around nailing every course. If you're going to cheat, what about nailing every other row.

Clip the eave and verge tiles as a minimum....clip and nail every tile in areas of high exposure.

Marley have a chart giving fixing guidelines for different areas of the Uk.

Thanks guys, Marley fixing spec for it says basically fix every one if I'm reading it right?

Silly question then, why would you clip a tile rather than nailing it? Isn't it cheaper and easier to nail? Or do you mean do both?

Clips hold the tile nearer the tail where the wind is most likely to lift it..
We have in the past on a harbourside development clipped, nailed and fixed a tile batten across the top of the nibs.

Got it, thanks

" nailed and fixed a tile batten across the top of the nibs" - Without the clips I take it?

 

[Alastairreid]

No, double nailed, clipped and a batten nailed across the top each tile...double Roman if I remember correctly.
Council roofing, cladding contract on 6 storey flats ..probably the council architects who specified.
Never seen any tiles out in over 20yrs.

Silly question but how does that work with the next tile above if there's a batten nailed on top of the tile? Or is that just at the ridge? Excuse my ignorance

 

[Alastairreid]

Across the top of the tile above the nibs so jamming the nibs between 2 batten.
