We have a Versico roof, 060 EPFA, that is app. 6 yers old.
The main surface is great! The overlays have blusters/bubbles. These blustered/bubble areas have been attacked, eaten, by something and exposed the concreat, allowing leaks.
As no other area has been attacked, it is my feeling that if there were no blusters/bubbles, there wouldd be no attack and no leaks.
Has anyone seen this ?
What is the root cause, and fix?
