Chimney Leak? - Rotten wood, where do I even start? Help

I have no idea where to start. When walking up the stairs of the back patio I saw that the osb under the fire place was rotten. I know I could just replace and caulk it but it wouldn’t solve the actual issue. On the wood sides, the corners of the siding only are soft and definitely has potential rotten wood behind it. I see that the wood siding that’s next to the gutter is split. Possible that’s where the water is causing it? But on the other side in the small corners are also soft on the wood siding. So I think that maybe there’s another issue. The house was built in 1986, so it is old-ish. If I do just replace the siding + osb, do I just place the wood and use an outdoor caulk or some sort to seal it? Or do you think this is something I should call in a contractor or specific person? Or call someone to confirm/check the chimney cap (is that the correct term?) to see if it’s leaking? submitted by /u/ValinImproving [link] [comments]
