s!5 Clamps [RE-wrenches]

Hey Kirpal,

What Blair is referring to is much more important than the type of 
roofing.  Almost any of the residential standing seam profiles will 
work with S5! clips - at least the ones here in New England.

You may know this already from your post but just to make sure, 
follow the following:

1.  Never do a retrofit standing seam residential unless you can talk 
to the roofer and find out how it was installed because you don't 
know how well they attached the metal roofing to the plywood nor the 
plywood to the rafters.  Even if you can talk to them, mostly the 
standard method is inadequate unless an engineer says otherwise.

2)  If doing new construction;

a) Specify that the attachment of the plywood to the rafters be 
either screwed or diagonally nailed (slight angle to the nail gun 
when nailing aimed at the center of rafter).  If you are reroofing, 
strip the old asphalt before putting down the SS and have them 
upgrade the nailing.

b)  Double up on the clips from the normal 16" to 8" centers and make 
sure they use 2 screws (not 1 or 2 nails) per clip.

c)  Place your S5s on top of clips.  Be sure to determine your on 
centers for S5s from uplift as well as point loading from combined 
wind and snow.

Any deviation from this should really be run by an engineer.

Hope that helps!
