I had a metal roof installed on my house and now I'm pulling my hair out trying to figure out my racking options. The previous roof on my house was shingle. The metal roof was installed by nailing 1" purlins (furring strips) horizontally 24" apart directly on top of the shingles. The metal roof is then screwed to the purlins. The purlins do not line up with where my horizontal rails need to run. I need to run the rails directly along the purlins for effective anchoring.
Here's my question. How critical are the recommended clamping zones on the panels? Is this strictly for wind and snow/ice load? I'm considering running the rails (and clamps) outside of the recommended clamp zone. Sometimes as much as six inches outside of the recommended range.
Thoughts?
