Stainless Steel Slate Hooks or Copper Slate Nails?

[JamieK]

Hi There,

 

We're soon to have our slate roof replaced.

 

The current slate roof is 100 years old. House was built in 1923.

 

The old slates are being removed and replaced with new slates (300mm x 600mm, 7-9mm thick)

 

Our roofer has suggested using stainless steel slate hooks (grade 316, black coated).

 

He feels they're easier to install, hold the slate more firmly and slates can replaced more easily.

 

Our roof has numerous valleys and quite steep pitches down the gable.

 

Which would be the best option to hold the slates firmly in place for another 100 years?

 

Slate hooks or copper slate nails?

 

Are any of the above more prone to corrosion or other issues?

 

The slates have pre-drilled holes.

 

Thanks

 

Jamie

Slate hooks definitely as better overall , the only downside with hooks vs nails is you can see a very small amount of hook once installed

I used nails on our previous and was going to use hooks this time But my wife didn’t like the look of them There quite regional Which is probably why she doesn’t like them Never see them where we live In any case you still need to nail around the valleys

Whatever is done locally, anything thing else may look strange.
