Hi Bill,
It sounds like you’re talking about a purlin type setup – 4’ sounds a
little far apart but I guess that’s what you have to deal with. If you have
a corrugated metal roof, we’ve used S-5 CurruBrackets screwed through the
metal and into the purlins and then either run the solar rail up and down
the roof or install a sub-rack system (with strut or angle aluminum)
perpendicular to your solar rail.
Best,
August

Recently, a customer had a metal roof (not standing seam) installed by a
"handyman". Pretty clean installation however for some reason he ran 1X6
stringers across the roof on the 1/2" plywood deck spaced about every 4
feet (as you go from ridge to eaves). Of course the roofing screws are at
the stringers. I'm sure he had a *great* reason for doing so. So now I
have been asked to install an array on this roof. You can feel how "soft"
the roof is as you walk on it of course because you are walking on
air-below-metal for most of the roof. Stringer locations don't jive with
possible feet/post locations for rail. I'm usually pretty good at problem
solving but I'm accepting ideas.
