I want to add a roof type kitchen vent. I have a GE NoiseMaker microwave
mounted on top of my gas cooking range. It can vent out. I have decided
to put in ducting going out through the sheetrock ceiling and then out
of the roof. Two holes have to be made:

6inch round duct beng used.

1. 6inch hole in the sheet rock ceiling. (piece of cake .. easy)

2. a hole in the roof directly (about 10 feet) above the ceiling. Roof
is 5/8ich plywood with roofing felt with standard 3-tab asphalt
shingles. Here a vent has to be installed with damper.

Can anyone provide some tips for the 2nd step to prevent leaking after
the vent is installed. Any links to good damper and flashing systems.
Any instruction of how to cut the shngles and any overlapping methods
for the flashing on the vent. Any glues and caulks?

THis vill be done by a contractor.. he is good but he does not have
experience with cutting through the roof and making a vent hole or
hanlding shingles. But with enough care and reading I am sure we can do it.

Its hard to find contractors here that will just handle this as oppsed
to redoing the wole kitchen.

Any help appreciated!!

I have waited until the roof was warm and then gently pried up the shingles
that will not be removed. Cut the hole and tar liberally.

I have a sheet metal guy that makes flashings that slide over the pipe.
Like a big roof jack. Tar liberally. Depending on where this goes through
the roof a upstream flashing might be a good idea.

I once installed 8 ceiling fans through a friends flat roof. I had refused
to do the job unit he was ready to do a re-roof. 4 leaked 4 did not. Best
part was one that leaked was on his side of the bed. His wife and I got a
kick out of that.

It not that hard of a job any decent roofer can make the penetration water
tight. Think about it they Roof around vents every day. The other option if
its a outside wall go out the wall don't even go threw the roof. You just
need a seat metal guy to make you a eyebrow.They could the install most
likely

I was looking for a picture of a roof cap to show you. You will
need new shingles, you will need to remove some existing shingles.
The vent will require tar and shingles work. Always think like a
rain drop and assume that the rain will get through your first
shield, where will it go once it gets through? Here is a roof
cap:

While looking for that, I came across this. I have not watched
the whole movie, I hope it is fairly complete:

"Noisemaker"? You're kidding, right?

When I put in my roof fan, I followed the instructions that came with
it. It said to cut a hole in the shingles and paper and drill a hole
in the plywood, and gave a template, the same template for each cut,
bigger than the hole you would need.

Then it had me take the fan, with housing and flashing attached, and
slide it up under the shingles that were above the center line of the
fan. (I guess I had to take out a couple roofing nails.

The lower half of the fan went atop the shingles, and I suppose I put
in a few roofing nails and covered the heads with "black tar" caulk.
Maybe I caulked beside the edges as well.

Now I do have some mist on the floor in the attic when it rains, but
you won't. I have mist when the rain hits the roof and bounces into
the screen that is part of the fan housing. Some of it goes through
the holes, or hits the screen and part of that splatters inside. It'
s barely moist inside. But you won't have a screen.


I can't find the instructions right now, but I would just see what
fans for sale in the store now say.

THis vill be done by a contractor.. he is good but he does not have
experience with cutting through the roof and making a vent hole or
hanlding shingles. But with enough care and reading I am sure we can do it.
