Simplified roof vent code compliance

By TUBOS Inc.  

A user-friendly vent pipe extension helps roofing contractors meet vent height requirements and prevent costly leaks. 

When vent stacks sit too low on a finished roof, contractors risk more than just code violations; they risk leaks, costly repairs and even structural damage. That’s why roofers and builders rely on the TUBOS vent pipe extension, a simple, effective solution designed to quickly bring vent pipe heights into full compliance with building code requirements.  

Easy to install and compatible with standard pipe sizes, TUBOS provides a durable and code-compliant way to raise vent pipes without complex fabrication or added labor. Proper vent pipe height is essential for roof performance and occupant safety. When vent stacks are too short, trapped moisture and backed-up gases can compromise both roofing systems and indoor air quality.  

The International Plumbing Code (IPC), requires plumbing vent pipes to extend vertically at least 152 mm (6 in) above a roof, per Section 905.5, "Vent Connections and Grades." Additionally, vent pipes must be at least 305 mm (12 in) away from a vertical surface. In locations known for snow, the vent pipe needs to be at least 51 mm (2 in) in diameter and 305 mm inside an insulated area of a building before extending through the roof. Vents in these locations also should extend 610 mm (24 in) above a roof. 

Advantages of TUBOS prefabricated vent pipe extensions 

• Ease of installation: No special tools are required to size and install TUBOS securely into openings of existing plumbing vent pipes. Standard hand tools (tape measure, manual or portable battery powered saw, caulk gun) are all that is needed for installation. 
• Design simplicity: TUBOS are manufactured for use with standard diameter vent pipes. TUBOS are prefabricated with integral six-inch long pipe joint splice sleeve inserts at each end of every unit. 
• Economical: 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 lets you quickly get on with your project. 
• Average time to install: Three minutes 
• Average material savings: $35 dollars each
