roofers [RE-wrenches]

[Tom Simko]

 The below is why I pole mount, roofers and PV is like a bull in a china
shop, not a good combination! I was/am a journeyman carpenter and I can
assure you the roofers are at the bottom of the food chain in the
construction scene, and re-roofers are below them! I have been fortunate so
far in being able to always pole mount, I talk my customers out of roof
mounting as I can see it being a pain down the road, whereas the pole mounts
NEVER need to be messed with. I guess if its a surburban environment the
looks might count, but beauty is in the eye of the beholder! PV on a roof to
my carpenter's eyes looks like trouble, and I will only go that route if
there are NO other options.
