We use the SDS galv up here in the mountains, they are tough, haven't
snapped one, the engineer loves spec'ing them.

The Simpson screws look very similar to the Headloks.  I just looked at the
Simpson SDS, and I see they are available in 316 Stainless as well.
That would be my choice near the ocean, but I'm guessing they're spendy.

I believe it's best to have the screws go into purlins. These are
fairly low cost; contact me offlist if you want me to send you
distributor contact info.

As far as figuring out what manufacturer/model of roof you have
that can be tough. Maybe find original building drawings or a
sticker somewhere on the underside? I've also found that the
folks at S-5! are good at figuring out manufacturers.

Good luck! -August

Friends:

I am trying to specify attachments for a corrugated roof.  This is the type
with the sine wave shape.

I want to try the DPW CMB product line.  I have been instructed to provide
measurements of the corrugation from peak to peak and also the height from
valley to peak.  The problem is that the measurements vary from point to
point on this roof.  In some places the peak to peak is 2.75" and in others
it is in the 2.6" range.  The height varies from 0.625 to 0.5 inches.

I have looked on-line and I find that a common dimension for roofing peak
to peak is 2.67".  There are products with height measurements of 0.5 and
0.875.

I have a few questions:

1. How do I figure out which roofing product I have?
2. Does it matter if the spacing varies from one location to the next?
3. Does anyone have experience with the CMB product.

Thanks in advance.

The SnapNrack Corrugated Roof Block will work with that roof - I'm sure DPW has 
one that will work as well but can't say which size -
