Consulted a roofing company for a metal roof. Got estimate and asked questions concerning vent pipes for metal roof. Roofer stated that metal roofs can and be with without them. Read a reply here in one of the forums that metal roofs are installed without vents. if so, How are the sewer gases vented from home without cutting holes in roof and installing vent pipes that are on traditional asphalt roofed homes. Is this possible?

Per code, these must be vented to the outside. There may be some confusion going on here between plumbing vents and attic exhaust vents. Attic exhaust vents are important too but the standard ones can be replaced by a ridge vent and also a hot roof is an option for eliminating attic exhaust vents.

Plumbing vents were in question. Please elaborate on these per original question.

Per code, these vents must have unobstructed venting to the outside.

+1 You don't want those fumes dumping into the attic.
