We Will Title This "Dodging A Bullet"

---

This customer was seriously considering replacing the roof on their home which as you can imagine would have been 5 figures easy.  We were called out to do a routine roof cleaning and were told the roof was mildewed very badly. As we started to examine the roof we started to notice the substance didnt have the normal appearance of mold or mildew. We threw chlorine at it and I honestly thought I heard the roof laughing. We went out and purchase some serious commercial grade grime cutting chemicals and the roof only laughed even louder. Determined not to let the roof have the last laugh we purchase 1 of every chemical we thought would stand a chance and on our 5th chem there was no more laughter from the roof. This was a sealant that was put on the roof to protect it but somehow backfired and made it look worst over a period of time. And literally made it almost impossible for any other chemical to clean it. Once we found the roofs kryptonite  that would weaking and remove the coating we were able to proceed with the typical cleaning we would do with any other roof.  

Needless to say Happy Happy Customer
