Roofing/Orange/Yellow Dripping

Question
I have a strange orangish sort of waxy or oily stuff dripping around the outside of my furnace chimney into my basement.  Do you have any idea what it could be?  
My house is from the 1920's, and a new roof was put on about 7 years ago.  I've lived there since 1987 and have never seen this.  The furnace is gas.  I live in north-central Ohio and this has been the coldest winter I can remember.  When I first discovered the leaking into my basement I went to the attic and found that it seems to be coming from the roof, and the substance is running all the way down to the basement, and on all four sides of the chimney.
I looked online (which is how I found your site) but I'm not finding where such a thing is addressed anywhere.  I don't know who to call about it since I don't know what it is.  Would it be related to the relatively new roof - so should I call them because the roof is under warrantee?  
Is the substance dangerous?
Please help if you can!
Thank you!"

Answer
Barbara,
This is a strange one. I'm thinking that it may be some type of sealant or perhaps a foam insulation that may have been installed around the chimney, and due to the cold temps (thus the furnace working and putting out more warm exhaust) it may have caused some melting.
I quite honestly don't know what that product is. I'd start with the roofer and have him come out and see if it is something that they installed.
Sorry that I couldn't be more help - good luck.
