  • S5! Attachment Frequency

    How do I determine the frequency of the S5! attachments for my roof? I have a Midwest Manufacturing 26 gauge steel roof which is compatible with the S5! "S-5-N Mini" clamps. I purchased enough clamps for mounting at every other seam location and boy do these things have a positive mount and seem to hold like crazy. My roof has 16" seam spacing. Anyone have experience with similar standing seam attachments?

    -2 rows of 11 & 1 row of 12
    -Unirac Standard racking
    -8/12 pitch, standing seam steel roof

    it depends on your uplift requirements in your location. If you are in hurricane area or something then you would want to do every seam and a few hanger bolts to be sure.

    remember that the S5! holds onto the roof really well but how well is the roof attached to your house?

      Thanks Butch. I'm in Minnesota so no special hurricane requirements here. I agree, the weak point is probably always the roof attachment (with standing seem metal roofs). All I can find on the S5 website is here:
      but, of course, they defer to others to determine whether or not an attachment every seam is required or not. But it's still a pretty good document.

      I'd love to hear feedback if anyone has experience where they have seen these attachments used every rib vs. every other.

        You should be staggering though such that every other rail is attached to every other ridge. Thi si sthe same for non standing ridge attachements as well.
