Because no one has responded the first time around, let me post my
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.

Unfortunately there is no "standard" way to install such an item as there
are many problems to overcome: what attachment points are available? what
shape is the fan unit? what area is to be covered? is the fan unit installed
on a curb? Do you have a guard or must you build one?

A photo may be useful, but it is probably one of those things that one needs
to be creative in designing, building and installing the cage on the fan or
on the roof. Experience and adaptability are requirements of the installer,
anything we say over the internet is of little practical use if it doesn't
suit your needs or the conditions you are working with.- Hide quoted text -

The roof vent guard that I intend to install is like the one shown in

My round roof mounted vent is just like the one shown in the picture.
It has a fan inside. The idea is to use the "roof vent guard" that is
a steel cage to cover the round roof mounted vent. You can see from
the picture that the flange of the roof vent guard has a serie of
holes in it (other models from other web sites also have similar
holes). This seems to suggest that I am supposed to nail it in
place. I will need to give this whole idea a second thought because I
am afraid that all these nails are going to give rain water a way to
leak inside my roof.

I may just have to follow the other newsgroup member suggestion to
stiffen the screen that is already there. I intend to remove the
screen and see if I can stiffen it later today.
