Insulation is not my trade so I'd likw to pick ya'lls brain
Southern New mexico so heating isnt near as much of an issue as cooling
I'm bidding to put a pitched metal roof over an existing built up flat roof. There is no isulation in the ceiling at all and from 6" to 9" cavity from top of plaster to bottom of deck sheathing. Thru the hallway I can blow cellulose into the whole ceiling. (foam would be better but with veggas and plaster it would be a nightmare for myself and the HO ) There is no pipes,duct work or reccessed lighting. I am rewiring it all but its all in flex conduit
I'm using metal and a radiant barrier under that for the pitch but I am wondering if blowing say 10-12 inches on the top of the old roof is worth doing? I have called cacoon insulation and another co and they have no idea saying they have no case studies on such a application over a roof.
being a tar and gravel I plan on shoveling off about 4 inches of peagravel
to compenstae for the weight of the new pitched roof I'm wondering about any possile reaction of cellulose and the old roof tar????
Thank for any thoughts on this
