Question plumbing question

My kitchen sink and bathroom sink make bubbling sounds after all the water has been drained from the sink. I went up to the roof and looked at the vent pipes for obstructions (as told by a co-worker) but could not see any. I snaked the vent pipes with a 15 ft. snake for the heck of it with no success. Is there any other ways of solving this problem other than getting a longer snake and going back up to the roof? Could it be something other than the ventilation for the drain system? Please advise. Thanks.

A vent pipe obstruction would more likely cause a trap to be siphoned out, allowing sewer gas back into the home, although that could be the problem.
You can try flushing the vent with a water hose sprayer.
Sounds more like a partial clog in the drain line, however.
Open a clean-out plug, and snake the main drain line with a heavy-duty (rented) plumber's snake.
Good Luck!
