Hello,

I am curious for you HVAC experts whether a wire mesh cover is necessary for furnace vent on the roof? My HVAC guys says no way since it could lead to ice build up etc and looks like placed a 45. I tend to think you need something to prevent birds from nesting? Please disregard red circles - I recognize some of these are NOT hvac but just bath vents and radon vent.


Your thoughts?






Here is the cover I was thinking:

Wow - great info. Thank you so much guys. For sure, I am not going to put guards on HVAC vents but what about:

1. Passive radon pipe
2. Bathroom fan

Am I asking for trouble by putting grill/guards on these - see pictured above?

Many thanks and sorry for stupid questions...
