I smell exhaust type fumes in my home. Could it come from the roof vents? What can happen if they get clogged up?

the roof vents are meant to remove sewer gas from your plumbing it is toxic and highly explosive but smells like sewage or a rotten egg smell. Yes they can get clogged or broken sometimes by a careless roofing job or wasps or even spiderwebs. Don't go up there yourself. Exhaust fumes could be coming from your furnace call furnace repair or from your dryer check to see if it is clogged with lint or otherwise obstructed or from your car which you should not run in the garage for more than a few seconds before you back it out and always with the garage door opens. Hope this helps. Please write if you can so we all know you are ok. If this problem persists CALL 911!

If your roof vents get clogged you will have drainage issues like sinks not draining, toilets flushing slowly etc,etc. Does this smell seem like a cars exhaust or is it something else ? Post back and try to be a little more specific if you can I know smells can be tricky but they are even worse for us since we cant smell them at all. Are these odors making you feel bad or just bothersome odors ? If you feel this is affecting your health might be best to call in a contractor to have a look or a sniff(lol) and see what they tell you. Either way keep us posted and we will try to help if we can . Oh one more thing do you have any gas appliances , Fire places anything else. As mentioned in the previous post if it smells like car exhaust do you leave a car idling in a garage or on a carport even near a package unit ac system where the whole unit is outside any of these can bring the smell into your home. GOOD LUCK ,AC
