Tubos and Wide Single Ply Roof Jobs

When you need to extend multiple rooftop vent stacks on a new or re-roofing project, Tubos Vent Pipe Extensions has the perfect solution for you. According to code, roofing vent stacks are required to be a minimum of 8- inches above the surface of the finished roof.

When insulation is added during re-roofing the height of the stack is effectively shortened from the required 8-inches. The same thing occurs when installing tapered insulation or adding new lightweight insulating concrete.

What Contractors Are Saying

"Tubos is an excellent product that we use on many of our reroof projects. Whether we are increasing insulation thickness to meet additional R-value requirements, adding tapered insulation or pouring a new lightweight insulating concrete deck, there is always a need to raise the height of existing vent pipes. Tubos is a quick, easy and inexpensive way to raise vent pipes that will not leak and meets roof consultant and the membrane manufacturer's requirements. Thank you for providing this great solution." 
- Brent McFarlin - KPost Company, Vice President of Operations

“This product is a great accessory as part of a complete roofing system. When vent pipes need to be extended to accommodate additional layers of insulation, or meet building codes, we can now offer our contractors the ability to order the extensions directly from us when they order all their other materials.” 
- Steve Ruth, Duro-Last Vice President of Marketing and Sales

"Tubos, are you kidding me? Every commercial and/or residential re-roof contractor has run into a sub-eight inch VTR scenario, broken or as is. Before Tubos you had to enlist the plumber or get creative with an exterior sleeve, not ideal. These are great to stock in your Service vans. Foremen hoard them behind the bench seat in their truck. You cannot do a re-roof or a recover without them. Thank you Tubos, you have created a must-have for us." 
- Geoffrey Hagan, LEED AP Environmental Solutions Manager at Tecta America Florida 

‎"Tubos has invented an indispensable product that fills a huge void in the roofing industry. We like the product so much that it has become a permanent line item in our project specifications. Congrats on the idea and we wish you every success with your business." 
- Robert Whitcomb, AIA, RRC, Forensic Architect, Roofing & Waterproofing Consultant

‎"Your product is amazing, we have been using it for some time, I wish I had thought of it! We do a lot of tapered insulation installations which almost always require that the vent pipes be extended to a higher elevation to accommodate the taper and this is a lot easier, less expensive and faster than the old method of a PVC coupling which usually also required the use of a larger lead stack. The roofing consultants we have interacted with on projects that required extension of the vent stack also approved it quickly as they also see it as a way to save their clients money and still maintain high quality detail. Good Job!" 
- Darrick Gockerell - PSI Roofing & Restorations, President

Watch How Easy It Is

Each TUBOS can be used for two installations. After one end of the TUBOS is cut and installed, the opposite end can be retained for future installation at another pipe of the same diameter.

No fabrication time and minimal installation labor let you quickly get on with your project.
