Unfortunately, I seem to have a leak in my ground floor below a shower. I'm guessing there's a leak. I saw a bubble in my paint. I popped it – only a thimble worth of water came out.

A few feet away (in the downstairs bathroom), I've noticed there's an access panel into the roof. I'm guessing this will hopefully give some sort of access to the pipes below the shower. (https://i.imgur.com/ozL27vQ.jpg)
My main question is – I don't have the skill or experience to fix this myself. Who should I start with? Plumber? Are there dedicated companies that fix leaks? Should I involve my homeowners insurance at all?
