I'm in the process of buying a property built in 1977, and I discovered that the bathroom exhaust fan currently vents directly into the attic. The home inspection didn't find any mold, but I know it's not good for the moisture to be trapped there. I'm considering venting it out through the vinyl siding instead. The spot I found is about 20 feet away from the fan—do you think that's too far? I understand venting through the roof is ideal, but I'm a bit concerned since the roof is only a year old, and I really don't want to risk any leaks. I got a quote for $2300 for professional help, but I've heard that some quotes are just to make you go away. If I do go the pro route, who should I ask for help? It seems like I could get all the materials for around $200, although I do need a new fan. My dad says it's been fine for years like this, but I know I need to do something about the moisture issue.

You're right to think about venting it through the roof with insulated ducting. It’s not complicated, and there are loads of tutorials out there. This video I found really simplifies the process: [Link to video](https://www.youtube.com/watch?v=PqrZWd_CQIE). If you're planning to tackle it yourself, definitely check it out!
Venting out the roof is usually the easiest and most effective solution. It’s also generally the most cost-effective option. This is something you can do on your own if you're comfortable with heights—or you can hire a local independent roofer if you'd rather not deal with that. Just make sure to use insulated ducting to prevent any issues.
I just added that video to my bookmarks! Super helpful, thanks for sharing.
