How to Clear a Clogged Plumbing Vent Stack on Your Roof · Step 3 of 6
In this video
Securely position an extension ladder to safely access the roof. Carefully climb onto the roof, carrying the assembled vacuum hose. Have an assistant on the ground to turn the shop vacuum on and off on your signal. Sit or kneel in a stable position next to the clogged vent pipe, insert the hose, and push it down until you feel the obstruction. Signal for the vacuum to be turned on and work the hose up and down to dislodge and suck out all the debris.
Goal: Cleaning
- Always have a spotter or assistant when working on a ladder, especially when handling bulky equipment.

FAQs
What are the most important safety precautions I need to take before climbing on my roof to clear a vent stack?
Prioritize safety by always using a sturdy, properly secured ladder and ensuring it extends at least three feet above the roofline. Wear slip-resistant shoes, like the Shoes For Crews listed, and work gloves for better grip. Never attempt this project in wet, icy, or extremely windy conditions, and consider having a spotter on the ground.
My vent stack still seems clogged after flushing it with the garden hose. What should I do next, and how do I know if it's truly clear?
If flushing doesn't work, proceed to use a plumber's drum auger, such as The Plumber's Choice 25 ft. Drum Auger. Carefully feed the auger down the vent until you feel resistance, then work it to break up the clog. You'll know it's clear when the auger passes freely and you hear water flowing freely down the stack, or by running water in a fixture below and listening for improved drainage and no gurgling.
Do I really need a specialized drum auger, or can I use a different type of drain snake for stubborn clogs in the vent stack?
A specialized drum auger, like the 25 ft. or 50 ft. options listed, is highly recommended due to its length and ability to navigate bends in the vent pipe effectively. Smaller, shorter drain snakes might not reach deep enough or be flexible enough for stubborn clogs. Ensure any tool you use is robust enough not to break or get lost in the pipe.
The project is rated 'intermediate' and estimated at 4 hours. What specific challenges or preparations should I be aware of that contribute to this rating and time commitment?
The 'intermediate' rating stems from the need to work safely at heights, potentially handle specialized tools like a drum auger, and accurately diagnose the clog. The 4-hour estimate accounts for ladder setup, locating the vent, potentially multiple flushing/auger attempts, and thorough cleanup. Be prepared for the process to take longer if the clog is exceptionally stubborn or difficult to reach.
