Brown stain on roof starting at the chimney!

Recommended Posts

Hello Folks,

 

This is my first official post as a member of RCIA.  Be nice now!

 

Any way, I got a call from a customer today, and she is telling me that the stain on her two year old roof is from her oil burning furnace (NH). 

 

Can anyone confirm this hypothesis as being possible?

 

Is there a prescribed method for cleaning such a stain?

 

Thanx in advance.

spray some oxacalic acid solution on it. Should clean it right up Make sure all the SH is washed off first. The 2 chems DO NOT mix.

Use whatever you have experience with and/or feel confortable with. Just don't let them contact each other.
