We just had our roof replaced today, and I've noticed a distinct smell of natural gas at random times while walking through the house. When they were here they had large pieces of wood up against the garage to protect it and I noticed the garage reaked of the smell after they left. So I opened the garage to let it air out, and now it's fine. But I still have random smells theoughout the house that smells like natural gas (we do have a gas range and water heater).
Is this normal, after replacing our gas vent? Could this be something else that just smells like gas?
Fwiw, I have two young daughters in the house - kind of worried to go to sleep without figuring this out first.
