[RE-wrenches] Sharp racking on cement roof tiles

[William Miller]

Max:

We had a client who, on a barrel tile roof,  insisted on removing tiles 
from under the array but wanted to keep tiles below the array.  There was 
no good way to divert water from under the lower tiles.  The roofer first 
tried using some roll roof that cracked and then used lead flashing.  There 
was still a mosquito pond where the water pooled.  Also, the "built in" 
look creates cooling flow restrictions.  We eventually gave up on the built 
in look.
