Water found at bottom front of fireplace insert. Any ideas on steps to find/ fix it would be appreciated! I fear this water damage has been happening for a while now due to the rust- like color.

Noticed some very loud water drips last night from a huge rain storm, next day notice grout is damp and used a paper towel to find some water.

My roof was actually just replaced 3 days ago- great company/ project manager. Had it replaced due to age (30yrs old) lived here for 6yrs . I have noticed the dripping sound before but very mild and only could ever hear it when it was pouring. Well we had a major downpour last night and the dripping sounded 10x worse and intense like it was actually dripping inside somewhere.

I let my roof guy know, and he checked out around the chimney and wasn’t sure where it could be getting in at, as he said everything looked sealed and good, but suggested I try reapplying sealant to the chimney cap, and flue flashing.

Thoughts?

Thanks in advance for any advice!…
