I had my shingles replaced recently by a roofer.
Since that time I've been hearing clicks at night, some soft, medium
and really loud.

I've located the sources, two roof vents. One for the bathroom fan and
one for the kitchen fan.
I've talked with the roofer (he's re-shingling the house across the
street).

He's agreed to come back and take care of the problem.

What is the best method to use to address the problem?
He has confirmed that there are moving parts in the vents he
installed.

Are there bathroom/kitchen vents that don't have moving parts? Can you
recommend some?
If not, what's the best way to silence them/stop the parts from
moving.

I've told him that I don't use the bathroom fan (I disconnected it the
week after I moved into the house). I've used the kitchen fan maybe a
handful of times in the 14 years I've been in the house.

Thanks in advance!

Since I can't see your roof vents from where I'm sitting, I'm going to
guess that your vents have a spring loaded closure that keeps the
vents (somewhat) sealed when the fans are not on. The force of the fan
opens the vents and allows the air to escape.

My dryer vent is like that. It helps to (somewhat) keep the
conditioned air inside the house instead of letting it leak outdoors.

If you really don't use your fans (which I'll question later) then
they could be sealed shut, or even removed.

If you don't care about air leakage, they could be altered to be open
all the time so that if you did use your fans, the air could get out.

Now I have to ask: What do you do with all the moisture from your
bathroom? The main purpose of the fan is to remove the moisture so
that you don't get mold or peeling paint. Why don't you use the fan?

As far as the kitchen fan, we don't use ours all the time, but a
"handful of times in 14 years" seems pretty extreme. Don't you ever
burn anything? ;-)

We mainly use ours when we use the oven on hot days. Ours is an pretty
old exhuast fan mounted in the ceiling, not a hood over the stove. I'd
rather have the fan suck out the hot air that rises to the ceiling
than let it hang around and try to cool it with the AC.

I'm pretty sure the fan is the original from 1956 based on the style
and venting. It still works very well and I'll replace it if it ever
fails.

I usually use a second bathroom for showering etc. that has an HVAC
system pulling air out. Moisture has never been a problem in the first
bathroom.
No mold/peeling paint etc.
I don't use the fan because I don't like the noise (I know there are
supposed to be quiet fans, but this one is quite quiet already).

I rarely use the big oven and thus rarely burn anything. Literally
I've used the fan a handful of times over the 14 year period.
But I would like to keep it functioning for emergency situations.

I spoke with a fellow at an HVAC venting company today and he was
talking about attacking this from two different points.
He suggested a second 'back draft damper' inside the home and
weighting the damper at the outside vent head.

Does this sound like it would solve the problem?
I'm looking for a solution to completely remove all flapping noises
(inside and outside).

As long as the weight can be overcome by the force of the fan I guess
it's OK.

However, I'd be curious as to why you are hearing noises in the first
place.

I have 2 bathroom exhaust vents, a dryer vent and a kitchen vent.

I don't think I've heard a peep out of them *ever*.

Did the roofer replace the vents when he did the shingles? Mine did,
as part of the roofing job. (He also painted the stacks to blend in
with the roof better, nice guy)

If he didn't replace them, what did he do to them that they now make
noise? If he did replace them, what did he replace them with and how
are they ddifferent than the ones that were there before - the ones
that didn't make noise?

Yes, I asked him yesterday and he told me that he did replace the old
ones.
I also got him to repaint other stacks on the roof that had lost some
of their paint. He gladly did that. He's been very accommodating.


If he didn't replace them, what did he do to them that they now make
noise? If he did replace them, what did he replace them with and how

Yes, as I said he did replace them. The new ones are definitely
different than the original ones. I'll try to find out exactly how
they differ when he comes back.
All of this flapping noise has been occurring since he did the new
roof three weeks ago. And it's not taking much wind at all to get them
going!

I'd like to get to the bottom of this and really understand what's
happening.
Because it seems there could be two noises at play here.
The first occurring at the outside vent and also air coming down the
vent and flapping something inside the house near the fan.

Pretty close.
I don't cook much, it's true.
I use my counter top toaster oven for almost all of my cooking.

Panasonic makes and incredibly quiet fan for bathrooms. Barely know

The exhaust vents I have seen have some kind of flapper installed to keep
out wind, insects, rodents, etc. The flapper is normally closed until the
airflow from the exhaust fan blows it open. You could certainly remove
the flapper, but then you would probably have other issues with drafts,
insects, etc.

I have had similar issues with wall vents in the past. When the wind
blows it creates a suction that pulls air through the vent and causes the
flapper to "flap" in the wind, thus making noise in the process. My
current wall vents do not have that problem, so I don't know if the
springs are stronger or if it's just a matter of being located out of the
wind.

I suppose you could install a screened vent instead of a flappered vent,
but I would be concerned this would eventually clog up with dust and
other debris. This would also leave an opening for drafts to come into
the house.

I am assuming the old vents did not make noise, so I would look at the
differences between the old and new vents. Maybe the old vents used a
different design, or maybe they were just oriented differently so they
didn't catch the wind.

I've told him that I don't use the bathroom fan
(I disconnected it the week after I moved into the house).

You should always run the bathroom fan when showering and let it run for
several minutes afterwards to remove the moisture from the bathroom. It
may not matter as much in an old drafty house, but in modern sealed
houses you're just asking for mold problems if you don't use the fan.

If you don't use the bathroom often, you should still leave it functional
in case you need to remove "odors". Not to mention, many folks have
"bashful bladders" and appreciate the noise of an exhaust fan to mask the
sounds of nature, so to speak.

However, there are really quiet bathroom fans. I installed Panasonic fans
in our house and you can't even hear them running unless you get really
quiet and purposely listen for them.

I've used the kitchen fan maybe a handful of times
in the 14 years I've been in the house.

I don't use ours as often as I should, but the kitchen fan matters most
when you're boiling water (lots of steam to remove) or if you burn
something on the stove (lots of smoke to remove).

Good luck,

I'm going to seal the bathroom vent shut, as I don't use the fan.

Can someone recommend the best way to do this, considering temps range
from -25C to 38C.
Glues? Tapes? Other means?
I suppose screws would be best but the problem is that I couldn't gain
access to screw the two parts together. I don't want to take off
shingles etc. to remove the vent.
So whatever I do will be with the vent in place.

Before you seal it shut, consider that code typically
requires a bathroom to have either a fan or window.
So, if you don;'t have a window that can open, it
may very well be a code violation. As well as, IMO,
foolish.

Yes styrofoam would be a good 'plug'.
I would still have to secure it though with something.
But it really isn't workable as a fit for the entire vent, as there is
a grill on the face of the vent.
I would have to cut off the grills to gain access to the housing.
That seems way too messy.

I did buy some rubber washers to possibly plug the last (bottom grill)
where the flap rests. So the washer would stop the flap from opening
up.
But the washers would need to be secured as well.

So I'm thinking:

1. Crazy glue the flap.
2. Duct/electrical tape the flap.
3. Duct/electrical tape the flap + crazy glue.
4. Insert washer + variations of above...

So am I.

I put in a new bathroom vent a few years ago as part of a roof repair.
The new vent connects to the bathroom fan, and has a flap which
rotates about an offset axis to keep the vent shut when the fan is off.

I can hear the flap fall back into place immediately after the fan is
turned off, and I can also hear the flap fall back into place during
times of a strong wind blowing outside (I'm guessing due to Bernouli's
principle).

Sure, strong winds causing a flap makes sense. I used to have that
before the new vent was installed.
But now I'm getting flaps in moderate and slight breezes, which where
I live is very common.

It seems to me that you are going to all kinds of lengths to seal the

to fix the root cause of the problem - the vent itself.

Perhaps you need a different vent or a different location.

Had another thought. It's also possible the source of
the noise is not a flap in the roof vent itself. Mine have
no flap there, but the typical bathroom fan has a flap
inside it that closes when the fan is off. It's possible
the new roof vents are larger, oriented different, etc
so that maybe now the breeze is causing the flap in
the fan to make a noise.

That might also explain why it can be heard. I would
tend to doubt that ones located at the end of a hose,
at the roof would be capable of making that much
noise back inside the house. But then, who knows....

I'm still not sure what I'll do.

I went to a building supply store a few days ago to look at the roof
vents made by the company in question.
When I looked that the bathroom roof vent I immediately noticed a
difference between the one in the store and the one that the roofer
loaned me.

The vent company has made a change to the grill piece on the unit.
At first it appears there are just two parts (the main housing and the
flapper).
But there is a third separate part, the front grill where the air
passes through.

The vent I have on loan has a softer plastic for the grill.
The grill in the store had a much more rigid grill.
But the main thing though was the difference in noise they make.

For whatever reason, the flapping noise is much quieter on the store's
unit.
I just held the flapper at full height and let it drop several times
in a row.

So it seems the company is tinkering with their design.

The vent for my 2nd floor bathroom would be heard if it made noise.

The original exhaust hose used to make a 90 degree turn when it
entered the attic, then run about 10 through the attic and out an end
wall.

When I replaced the fan I ran the vent straight up about 2 feet and
out through the roof. Much more efficient, but literally within a
couple of feet of the fan itself. If it made noise, I'm sure I'd hear
it.

I've never had any of the condensation/dripping issues that I've heard
about, but I just replaced my roof and added soffit and ridge vents. I
don't know if the cooler attic will be an issue, but we'll see.

I know you said that there are differences in the design of the 2
vents, but I wouldn't necessarily assume that the noise difference is
related to the design change. It may be, but there are too may
variables involved for you to make that call in the store.

In one case you are holding a vent in a store and listening from the
outside of a vent that is not attached to anything.

In the other case, the vent is firmly attached to your roof, partially
covered in shingles, and attached to a vent tube that could be
transmitting the sound down into the room.

Stand next to a running car in your driveway, then pull it into a
garage. I'm guessing that the car will sound louder in the garage for
obvious reasons.

The only way to truly tell if the new vent is quieter than the old one
is to place both vents in fairly identical locations, using fairly
identical installation methods.
