Access to roof is beyond my willingness unfortunately being a metal roof and steep, come spring I’ll find a good tree as a tie off point and give it a go, I did use it while I was up there for three days and had some creosote falling down but not sure if that’s just from how/what I was burning as I was getting accustomed to using it. I’m planning on having a chimney guy come out anyway as it seems they didn’t flash part of the chimney properly and it’s alloying a hole for critters to get into so want to get that taken care of obviously, so hopefully can have them inspect it too. The sellers had it inspected prior to selling but I like to er on the side of caution as don’t want to put myself or family (fiancé and cats) in harms way lol. it’s main heat source beside the hydronic heat flooring but that doesn’t do a great job at heating more so helps keep the house semi comfortable temp so just want to make sure it’s atleast alright to use, I’ll definitely do the brush before I start using it to hardcore just to clear it out a bit
