Top 25 bad roof maintenance finds - Part 2!

Continuing the top 25 list, here is part 2 with the last 9! Enjoy...

Number 9

This plumbing vent on a metal roof always made me wonder, what in the world they were thinking this installation will prevent moisture intrusion. There is enough sealant in the world that will stop water here. Especially with a metal roof. In Houston, this roof will become a hot cookie sheet with our heat and will damage the sealant.

Number 8

This a perfect example of how vents age and require annual inspections. This box vent is warping and lifting the shingles, creating a potential water entry.
