Uncomfortable with heights, my weekend project hit a snag. Looking for someone who can help me install the vent for an exhaust fan on my roof. Everything else has been done/prepped, it's just the hole in the roof and installing /sealing the vent cover. I have everything ready and while I can get up there, I'm not comfortable moving around to install. Anybody that's comfortable with roofing work have 30-60 minutes to spare ?
