I am about to remodel my kitchen and want to install an exhaust vent.
How tall does it need to be above the shingles and how far from the top of the hip roof. I live in a two story house and the exhaust will will go through the attic about 4 feet from the edge. Can I punch a hole through the roof there or should I follow the pitch of the attic and come through closer to the center? If so how tall above the peak? Thanks in advance.
I would look at the fan installation instructions carefully and contact the manufacturer for their advice. Sometimes the type/length of venting/direction of wind etc can affect it and you may want their advice so it is not overloaded etc.
