PV on slate? [RE-wrenches]

[Jeff Clearwater]

<x-flowed>
Hi Nicholas,

3 best approaches  that come to mind for slate roofs:

1)  Reconsider doing it
2)  Pole Mount near the building
3)  Hire an experienced slate roofer to work with 
you and give as much of the liability as possible 
to them.

I don't mean to be pessimistic and I do encourage 
you to go for it - it would be nice to be able to 
respond to any roof type in the industry - but 
the little work I did with slate roofs in the 
early 80s with solar hot water in Vermont taught 
me that damage to the roof during installation is 
a major liability besides the issues of attaching 
mounts - especially the steeper you go.  The roof 
trac system from ProSolar for tile mounts might 
be of help - I'm guessing here - call em and see. 
. . .perhaps you can find other vermonters that 
have actually done it - but proceed cautiously! 
I know that's why you went to the list. I hope 
someone responds with some definitive experience 
here.  Let us know how you end up approaching it!

Best,
