Earlier today I posted a blog dealing with large trees near homes. In that, I described that a primary consideration for the home inspector is the amount of organic debris such a tree will drop onto the roof. Most homes I see have low-sloped or sloped roofs. When roofs that are designed to shed water cannot do so -- have no drainage -- that water has to go somewhere and it might be into the attic or the home below. The photos below are from the same house that was featured in the earlier blog.  It does not take much imagination to realize that all this debris is going to lead to no drainage, moss, moisture and other fungal concerns. Take a look at the right photo. That poor metal valley is not going to be able to do it's job.

Thanks for looking.
