Best practices for minimizing roof penetrations?
My house will have a gable roof with standing seam metal roofing. I’d like to minimize the number of penetrations to reduce the potential for problems over the long term.
The house is two stories over a basement. It is all electric with a bath on each floor. I know some devices, such as the kitchen and bath fans, can be vented out the sidewalls. But it seems like the plumbing stack and radon system have to go through the roof. Are there best practices for these types of situations that will help to ensure that I’m not having a problem with water and air leakage? Even though the house doesn’t have a fireplace, would I want to consider a “false” chimney as a way to get everything vented above the ridge line? Or am I being too paranoid?
