Has anyone experienced problems with laying flooring down over an existing flat, tar roof. To add a third floor, I could save time and money by not removing the existing flat roof, and laying the flooring (joist and sheathing) down over it. I am concerned with the changing temperatures causing a tar smell throughout the house. I would eventually open up some of the existing flat roof for stairs or a cathedral room, but would like to get use out of what is already there.
Sorry to those of you “breaktime nazis”, but I checked through the archives until my head hurt, and found nothing similar.

b NO ROOF FOR YOU!
That being said how big is the roof? is it roll roof or as you are insinuating tarred? roll would be an easy tear off. tarred depending on the sheathing might not be so bad either. I'd be inclined to tear it off and start with fresh, but then again I'm still wet behind the ears.
*3-10 years from now, you'll be glad you tore it off. The ONLY time you'll regret it is while you are doing it!

*pull it off. you will then know what you really have under it. you will have to remove some anyway to attach new system, so you may as well do it now. the other consideration is the inspector and yourinsurance company. what will they allow?
