Tubos, Inc., manufacturer of the popular Tubos line of pre-engineered vent stack extensions, has released an animated video for roofing contractors and distributors to make installation and installation efficiency quickly learned.  

Vent stack heights can become shortened when adding insulation on a reroofing project to meet R-value requirements. Municipal codes require stacks to be at a specified height above the roof and often fall out of compliance on reroofing projects.  

“Tubos units are designed to help roofing contractors do more with less,” said Kevin Morris, CEO of Tubos. “They are fast and simple to install and can be a real productivity enhancer on the roof, particularly if there are multiple vent stacks to address.”

Pre-engineered and patented Tubos pipe extensions are available in 2-, 3-, 4- and 5-inch diameters to accommodate most common vent stack sizes. According to the company's release, the line is fully compatible with cast iron and PVC vent stacks. Each Tubos unit has a six-inch internal splice sleeve that prevents water and moisture from leaking into the roofing assembly.

Tubos says its units install in four easy steps: measure, cut, seal, and flash. The company says each 28-inch long unit can be divided and used to extend two pipes; extensions can be up to 16 inches long. Tubos says its extensions are ideal for use where a tapered system is added, or a lightweight insulating concrete deck is used.
