I'm about to retile a 17.5 degree roof, quite possibly in Marley
Modern. The fixing spec for these seems to say that *every* tile needs
to be clipped, which begs the question - how do you replace any of
them if they crack? The old tiles (Redland Delta's) were only clipped
on the verges and nowhere else - mind you, that might be why 10% of
them were cracked!

Before you ask why I don't just get new Redland's, a) they don't make
them anymore though they are available on eBay, b) they don't have
nail holes and I can't find eaves clips for them, c) if I use
something different on the garage then I'll have enough left over to
replace all the cracked ones on the house and make a few bob on eBay
with the rest to defray costs.

If you use marley mods, you just nail every third row, ignore the bull****
on the data sheets.
Marley mods have nail holes, so if you need to replace a broken one that has
been nailed, you slide the one above it upwards, and wrangle it out and
replace and re-nail.


Also, if you are going to the expense of re-roofing the entire thing, don't
scrimp on the wooden beam mentioned in your earlier post, take it out and
replace with new, well treated timber, locate the cause of the rotting of
the original and don't forget to treat the end-grain with a good soaking in
a quality preservative, I usually leave timbers standing in a shallow tub of
preserver overnight if they are as important as this.
