How do you unclog vent pipe?

To unclog a vent pipe, first, ensure safety by using a ladder to access the roof where the vent pipe exits. Remove any debris or obstructions from the top, such as leaves or nests. If the clog persists, use a Plumbing snake or a hose with a high-pressure nozzle to push or flush out the blockage. Finally, check for any signs of damage and ensure the vent pipe is properly aligned and sealed.
