When up on a commercial roof, you surely see that there is a large amount of piping that runs on top of a roof. Gas lines, chill water lines, electrical conduit, and condensate drain lines are just some of what you may see running across the flat roof surface. But have you ever noticed the rooftop pipe supports?

What many people don’t know/understand, is that these lines need to be supported up off of the roof’s surface to prevent damage to the roof me membrane. 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. A 120 foot span of pipe can move as much as 1.5″ in 12 hours when heated up by the sun during the day, then to only be cooled off by the nighttime air. This constant expansion and contraction of the piping can cause severe damage to a roof; significantly shortening, or ending, its life span. This is why proper rooftop pipe supports are a necessity.

Without the proper type of rooftop pipe support, the expansion and contraction of the piping will eventually push the roof membrane around resulting in a leak in the roof. This can happen in a time period as short as a year! Now imagine that, a building owner pays as much as one million dollars for a new roof, only to try and save a few thousand dollars on the pipe supports. Inevitably, within 12 months his new roof is already leaking because he failed to have his contractor purchase the proper rooftop pipe supports, and it costs him tens of thousands of dollars to repair. From this example, you can now see why purchasing the proper rooftop pipe supports is a key element to properly protecting the roof of your commercial building.

A proper rooftop pipe support holds the pipe up off of the roofs surface while still allowing for the expansion and contraction of the pipe itself. Some rooftop pipe supports allow for this by setting the pipe on a roller type support, while others allow for the pipe to be suspended from a pipe hanger support and the vertical arm that holds the pipe swings back and forth with the pipe movement.
