slate guys: Advice needed

Broken_Roofer

I realized you mentioned they were stainless after I had posted and quite frankly was too lazy to go edit my response. Sorry.

What was their concern if the metal wasn't loose enough to pull up a corner to see what was underneath it? Just noticing that the nails were backing out and being proactive?

The owner is trying to get the manufacturer to warrant the low slope section of the roof for mechanical damage. I told her I did not think it was the manufacturer or the roofers' fault but she didn't want to hear it. I'm bowing out of the process because I hate litigious wenches.

Im sure I know what the problem possibly is.
We use a lot of that Zinc/Aluminium ridging up here in Scotland.
Its fixed to a ridge roll(the timber is flat on bottom & U-shaped) which is sometimes fixed through the hip joist with 5" "blacksmith nails" on older propertys.
These nails were super sharp when new & were shaped like a dagger blade, which frequently broke off leaving the Ridge/ridge roll loose.These timbers also get so old they wont even accept nails or are totally rotten where old nails are lying rusted & rotten in the timbers.This is the sort of problems we come across in places like Edinburgh/St Andrews with a lot of slated roofs.
I dont know if its the same setup but the design should be roughly the same

My. $.02

Expansion & contraction of the hip metal may loosen nails.

Well I wrote them an estimate and gave them no guarantee. If it doesn't work I will sell them a slate remove and reinstall on the turret to see what's going on under neath.
