Defect: Improperly flashed drainage waste vent on roof (location). The boot
and vent has tar applied over metal boot instead of a metal flashing system.
Cracking is visible in tar and at pipe boot junction. This is not a permanent
seal method and will allow water intrusion in gaps between boot and pipe and enter
the roofing system. Major water intrusion can lead to major damage and costly
repairs below this point. Recommend boot to be replaced and properly installed
by licensed, qualified roofing contractor.
