Hello all,

I'm having a new house built, and today I noticed something that I wanted
some opinions on...

My laundry room is not on an exterior wall of the house, so when they
installed the dryer vent, it is run straight up and through the roof. It
is the rigid (smooth) aluminum material, not expandable "accordian" hose.

Is having the vent run straight up from the dryer a problem? I've never
seen that done before. Any "backpressure" issues from this? My thoughts
are that hot air rises, so would probably be a good thing. True? Is this
the normal way of doing it? Thanks for any info you can provide.


The only problem that I have seen with these is that the roof tends
to get covered with lint. It is unsightly, but hardly a problem
otherwise. A good rain storm cleans it, that or a water hose.
