How to Clear a Clogged Plumbing Vent Stack on Your Roof · Step 4 of 6
In this video
With the bladder securely in the pipe, have a helper turn on the water supply to the hose. The bladder will inflate, sealing the pipe, and then shoot a powerful, focused jet of water forward. This high pressure is designed to dislodge and flush away even very compacted clogs. According to the video, this can clear the drain in a matter of seconds. Once the drain is clear, turn off the water.
Goal: Unclog the drain pipe
- Stand clear of the drain opening, as there is a possibility of water and debris splashing back out of the pipe.
- You will likely hear or feel when the clog gives way. Let the water run for a few more seconds to ensure the line is fully flushed.

FAQs
What are the most critical safety precautions I need to take before getting on my roof to clear the vent stack?
Prioritize a stable ladder placement on level ground and always use non-slip footwear, like the Shoes For Crews listed, to prevent falls. Avoid working on wet, icy, or extremely windy days, and consider having a helper spot your ladder and assist. Wear heavy-duty work gloves to protect your hands from debris and potential sharp edges.
How can I be sure I've identified the correct plumbing vent stack on my roof?
Plumbing vent stacks are typically 1.5 to 4 inches in diameter and usually located directly above bathrooms, kitchens, or laundry rooms. If unsure, have someone run water in a sink or flush a toilet while you listen near the vent pipe on the roof for gurgling or suction sounds that indicate it's connected to that fixture. You can also trace visible pipes in the attic if accessible.
Do I really need a specialized drain auger, or can I clear the clog with just a garden hose?
A garden hose with a high-pressure nozzle is often effective for clearing minor clogs like leaves or small nests. However, for stubborn blockages, such as compacted debris or animal nests deeper within the pipe, the THEWORKS 3/8 in. x 25 ft. Drain Auger is essential. It allows you to physically break apart and retrieve the obstruction that water alone can't dislodge.
What should I do if flushing with the garden hose doesn't clear the clog?
If the garden hose method doesn't work, it's time to use the drain auger. Carefully insert the auger into the vent pipe, feeding it down until you meet resistance. Gently crank the auger to break up the clog, then slowly pull it back, hopefully retrieving the obstructing material. Repeat as needed, flushing with water periodically.
