question one last time before I give up:

I need to know the way to install a roof vent guard over a round roof-
mounted vent fan.

The round roof-mounted vent fan has a screen covering the air outlet.
But the screen has no frame to stiffen it. Consequently, squirrels
push the screen away easily. They lived inside the roof for some time
until I finially get rid of them. Now, I am sure that no squirrel is
inside my roof any more. I need to keep any new comer away.

I want to install a square steel cage over the round roof-mounted vent
fan. The problem is that I cannot find any instruction about
installing it anywhere in internet (they only say that it is easy to
install). Therefore, I am not sure if this is something that I can
do. I don't want to nail it in place because I am afraid that I may
add a way for water to leak inside the roof through the nails.

One thing that I want to point out is that I have a very low pitch
roof. The roof doesn't have any shingle. It is covered with a thick
layer of roll-roofing. I am not sure if this makes any difference or
not. I want to mention about this in case this makes any difference.

Please tell me the appropriate way to install a steel roof vent
guard. Thanks in advance.


How about replacing the existing screen with something more substantial? I
bet the original was designed to keep out leaves, maybe insects, but yielded
to the attacks of a tree-rat.

You could use the existing screen as a template to cut a replacement from
hardware cloth, rebar, or similar.

Sounds good. He mght also be able to attach the new screen to the old
screen.

SEe what hardware stores sell for screen. What does one call the
heavy screen with 1/2 x 1/2 inch holes? We used it on a back door
with a window to keep a burglar from breaking the window and opening
the door.

Can you provide the name/model of the existing fan? That way we could look
at the manufacturer's picture and maybe come up with some other ideas.
