Ducted exhaust hood

I'm not sure which section to put this in so here goes...

I'll be remodeling our kitchen in the near future and I've a quandry - there is an existing ducted exhaust in the kitchen but I'm uncertain whether to tie into it or just install a new run straight through the roof. House is ranch with insulated crawlspace attic and range will be on an interior wall. Either way I'll have to get into the attic (respirator.tyvek suit). I'm wondering with a straight vertical run, what kind of damper need to be installed in order to keep heat from escaping all the time.
The existing duct ran off a ceiling fan which, as you can imagine, was worth next to nothing if it ever worked. As we never tried to use the current fan, I don't know if the ductwork is clear or not.
Also, if I'm going to go through the roof, I'll need to get cracking since it's mid-October and will be getting colder soon here in upstate NY.

Thanks,

Skip

Re: Ducted exhaust hood

I don’t know what your cooking habits are but for me if it’s going to smoke it goes out on the grill and I grill year round in a four season climate. However, I live in a very dry climate as well so steam and moisture are not something I concern myself with. I don’t know what that is like. The last few homes I have owned have had non-ducted range hoods and that works fine for me.

But, I have a “thing” about holes in my house, holes that see my hard earned heating dollars go flying out of. I go so far as to seal and insulate bathroom exhaust fans in the winter months.
