More S5 standing seam attachments spreads the load onto more of the
metal roof fasteners. In Oregon, the Structural Code, requires a
standing seam attachment every 24" maximum. Since the common
standing seam panels are 16" wide that means one attachment per seam
-- a lot of attachments. Never had one come off even with 32" or 48"
spacing, previous to current code, but I'm not in area that gets
serious winds.<br>
<br>
S5 also makes attachments designed for other types of metal roofs,
the mix of discussion of standing seam clamps and clamps design to
attached to decking or to purlins has made this topic a bit
difficult to follow.<br>

Friends:
<div><br>
</div>
<div>I have figured that the best way to improve a standing seam
installation is to add more S5 clips. Each seam has a finite
number of fasteners into the sheeting. Therefore if you attach
to more seams you attach to more fasteners into the deck. </div>
<div><br>
</div>
<div>We double the required number of clips at the perimeters and
always stagger our clip pattern to attach to the maximum number
of seams. </div>
<div><br>
</div>
<div>Does this logic make sense?<br>

<div dir="ltr">It's interesting that you experienced this as
I've always told customers that the roof will come off the
building with the array attached before the array comes
off the metal roof. Sounds like the issue was with the
attachment (or lack of) between the roof and the
building.

would add that S-5s are only as good as the roof.
We saw a large system (not ours) that ripped the
metal right off the roof during Hurricane Irma. It
literally tore the meta. The panels, rails, and
S-5s were still connected, sitting on the ground
with chunks of metal roofing still attached to the
S-5s. It was quite the mangled mess. We salvaged
quite a bit, but the client built a ground rack
after this.</div>
