Sometimes you just gotta wonder what they were thinking!
This finely installed plumbing vent boot flashing was found during a Lexington, KY Home Inspection a couple of days ago. .
Someone didn't look at the instructions that say "This Side UP!"
Ten feet away was another one (of the same apparent age), installed right!
I guess the second time was the charm as they got it right. I wonder why they didn't take the time to come back and do this one right.
The plastic and rubber boot flashings are commonly dry rotted at the top after about six or seven years. Have you checked yours lately. Most people don't notice until a mold spot starts growing on the ceiling.
