From the top of a commercial roof, it is easy to see the large amount of piping that can run on top of a roof. Gas lines, chill water lines, electrical conduit, and condensate drain lines are just some of what you may see on top of a flat roof surface.

HVAC ducts run across the tops of most roofs, and these ducts carry air to separate parts of the building. These ducts will often run across the top of the roof, but at times they may run below the roof also.

The old business model for pipe hangers of having a large distribution network with many different reps in the chain is now getting more and more outdated with the tools available through the internet.

A roof top conduit support is capable of holding many different lines at one time, especially when the lines are all running parallel to each other.

In a 24-hour period temperatures can vary as much as 50 degrees Fahrenheit. This change in temperature causes the material in any type of piping to expand in the heat of the day and contract in the cooler temperatures of the night.

Majority of the time, a rooftop duct support is made of sheet metal. This is a consistent element. The two things that are not consistent though, are the shape of the duct support and how it attaches to the roof.
