Round shapes can also be mounted with S-5!®, eliminating unsightly and corrosive wood blocking. For gas piping, electrical conduit and condensate lines, S-5! is the solution.
Mounting Pipes / Conduits on Metal Rooftop
Most model codes provide that if gas piping is run within the building envelope, the joints must be welded. If run on the rooftop, threaded joints may be used. There are significant cost differences in the two methods threaded joints are much more economical. It is also much easier (less labor-intensive) to install gas piping on a rooftop than overhead within a building. For this reason, gas piping is often roof-mounted.
Wood blocking is typically used to shim the piping above the panel seams. The long-term effects of wood blocking on coated steel roofs (shown in the photo) will void the roof s warranty. To keep the piping from migrating on the roof, all kinds of nasty things are done to the new roofs most of them involving the punching of holes in the panels and (temporary) externally applied sealants (which fail over time). The result is leak problems, repeated maintenance and warranty violations.
The S-5! solution: Gas piping is mounted above the panel seams using S-5! clamps. With S-5!, there is:
No wood blocking.
No impediments to roof drainage.
No holes in the panels.
This close-up photo shows how a small piece of Uni-strut and a pipe clamp were used to facilitate the installation. Electrical conduit is mounted in a similar fashion.
