TUBOS are pre-fabricated plumbing vent pipe extensions. When a commercial building is being re-roofed, typically additional insulation is added to the roof to come up to compliance with R-Value requirements as set by the International Energy Conservation Code (IECC). Minimum insulation R-Value requirements for non-residential applications above the roof deck ranges from R-15 to R-40. As insulation is added, vent stacks typically fall out of compliance with the vent stack height requirement over the roof deck. When this occurs, the vent stacks must be extended to stay code compliant. Tubos Pipe Extensions are designed to fit into 2-, 3-, 4- and 5-inch diameter PVC or cast iron vent stacks and can be delivered directly to the jobsite, eliminating the need for your crew to take a special trip to the hardware to pick up pipe boots, clamps, and PVC that does not provide an effective extension and will not fit correctly on existing vent stacks. You can purchase Tubos directly from your roofing or plumbing distributors of choice. 

When you have to extend multiple vent pipe extensions on a re-roofing project, Tubos Pipe Extensions offers a tried-and-true method for reducing jobsite costs and labor, particularly on projects where wide 10-, 12- or 16-foot membranes are being installed. 

In addition, rolling out wide and heavy rolls of membrane and cutting around many vent stacks is both time consuming and labor intensive. As a productive alternative, roofers should consider the following process:

1. Once the insulation is installed, cut all the existing vent stacks to a height of 1.0- to 1.5-inches above the insulation.

2. Roll out the membrane over the shortened vent stacks, making it easy to find and cut holes around each of the shortened vent stacks.

3. After securing the membrane, measure and cut each Tubos Pipe Extension to the proper length, and install into an existing vent stack as you work across the roof.
