This client had another roofer show up before me to look at the leak coming down into the inside of the fireplace. This other roofer tells him its the flashing. Although the flashing is not very pretty it's obviously a brick masonry problem. He argues with me for a while ( because this other guy has him convinced ) and I just let him speak. When he finally stops I pull out the Android tablet and he says quote: "Well, why in the hell did that A$$h0l=# lie to me like that?" lol I referred him to a good brick mason and left my card for future reference.
