I getting ready to reroof my house, to standing seam metal.
I have two toilets, 4 sinks, 2 showers, one washer.
I have an accessible attic.
Can I plumb all the current vents that pierce the current roof, into one single larger vent?

Purpose being to clean up roof clutter, move the main vent to back yard side of the roof, and reduce potential future leak sources?

Cost is not an object, but not sure if they will interact adversely, or long runs are a problem, or something else?

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
