Manstard Roof - Slipping tiles - Nails

[whiteshadow]

Hi,

We've got a really old cottage with a tiled mansard roof. The bottom slope (approx 80 degrees) has slipping tiles, and if you try and put them back it's like playing ker-plunk and they all start slipping. I'm firmly of the opinion that this has been bodged (~1980s) as not all the tiles are nailed (shouldn't they all be fixed at the near vertical angle!!?) and the gal. clout nails used are so short they don't even reach the batterns!

It's above a flat roof I've just replaced, so I'm ok with removeing and fixing them, but should I use copper or Ali nails??.....Sort of thought they need to be soft in case I have to lift them, otherwise I'd screw them in as the hammering casuses more to slip!!

TIA!

Sounds like it needs redoing, copper nails if you want it to last.

If you take it off and redo it you will be able to fit some kingspan or celotex.

round here (coastal) we use stainless. Roofers formerly used bronze.

I might well nurse the roof this winter and redo in the spring. Why would you use copper over Ali??.....Just longevity? I quite like the way I could tear off the tiles with the Ali clouts, would that be hard with copper ones?

Copper come out easy too
