A monkey with a crayon must have found his way to this roof. A local realtor who calls us often needed help with this home. I'll post the afters once we get to it.

I am not sure what they tried. It looks like it might be a pencil point from the ground. People will do the strangest things to save money and make money. Very few ever pay off.

Reminds me of this one I did a few weeks ago.  The homeowner said "I had a guy from my work try to clean it, but he said he couldn't find anything that would work."  No idea what he tried.
