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?

If it's anything like my house we open the bathroom window.

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? ;-)

Mabee they don't cook? Or just use the microwave. (or the BarBQ on the
back deck)

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.
