[RE-wrenches] How much rail to leave behind and skirts

[Solar Energy Solutions]

Speaking of rails...  What are thoughts about how much rail to leave sticking out from an array.  It seems the industry has moved towards trying to make the rails invisible by designing them to be cut at the edges of an array.
I don't like this practice and try to leave at least 4 - 6 inches sticking out.  The reason for this is to make it easier for those who follow when the roof needs re-roofing.     

We also don't install skirts as we believe this hurts the efficiency of the system... but are open to hearing the contrary.
