On one of my inspections yesterday, I encountered an absolute mess of a job performed by a roofer I will not mention.
A new roof was installed a few months ago without replacing the chimney step and counter flashing and now the deteriorated flashing has started to allow water intrusion into the home. The roofer was called out again and this was the initial fix:
Not only did they not replace the flashing (again), they covered the cracks on the crown with sealant that I now have to remove before correctly repairing the crown.
All of this could have been prevented if the job was done correctly in the first place and it would have also prevented the water damage that is now inside of the home.
