Can't get on the roof yet, it is covered in snow, hate to go up there and fall off.
I don't have brick chimney, looks more like an insert type. When I was up there in the late fall,I did notice the silcon seal seemed to missing in places. I redid the seal, but it doesn't seem to have worked.
When it gets warmer out I will have to go and look at it again or get someone out to take a look at it. Thanks for the help
