attaching vent to soffit
I am attaching a plastic bathroom exhaust fan vent (like a dryer vent) to an aluminum soffit.
Should I use long enough screws to go thru aluminum soffit panel and into the old wood soffit above or would just using small sheet metal screws to attach it to the aluminum only be sufficient?
I prefer to do the later but what is the best method?
p.s. if it makes a difference the vent is attached to the duct with tape and a clamp.

Should not be running it out the soffit at all.
Side wall or roof only.
Doing it your way the hot moist air can get sucked back into the attic and take out the sheathing on the roof.

Not the best one to answer, but al soffits are rather stiff if i remember and should be able to support that with no problem. Worst case they let go and you then run a longer screw up into the wood.

The problem with only screwing into the aluminum is in the event anyone ever pushes down on the metal collar of the vent... it would rip the piece of aluminum soffit down. But I suppose if its inside a soffit its not like anyone is going to step on it.

Not assuptions, well know facts and the proof is in all those pictures.
Hot air rises, well known fact for century's.

But even though he's unwilling to show us (or explain in any detail) what his soffits consist of, he wants answers--NOW!
Sorry, but I think I'll pass.
As an aside, those are some great pix, Joe. They remind me of the book I've always wanted to write--"How Not To Do Home Repairs."
