I need to install a exhaust fan for a bathroom in Dallas Texas on the first floor. The home is two story home. There are two optionsto exhaust the air out. One is exhaust the air out on the side of the home through a brick wall. The other choice is to exhaust the air by cutting into the drywall and fireblocks all the way up into the attic and to the roof.
Which choice is better for long term for making sure there are major problems in the future. Cutting into the brick for a side wall air venting or out the roof?
I understand that a core drilling is used to cut into the brick and everything between the outside to get to the inside but I am not sure if this would cause any long term maintenance issues for cutting into bricks versus the roof access.
