Furring Strips For Radiant Barrier


I am getting my flat roof replaced. In the roofers bid they will install furring strips on the old slatted decking to build up low areas to control the ponding problem I currently have. Then they will install 1/2 plywood on top of that.
I wanted a radiant barrier, but roofer says I need at least 3/4 inch between plywood and decking for it to work.
I was wondering I could staple radiant barrier on existing decking, and then install 2 in furring strips on the entire roof. Plywood would go on top of that.
Would this work? How close would the strips have to be to support 1/2 plywood? The flat roof is 2 levels, each about 1200 sq ft.

I have not had a chance to contact the roofer about this, but would like to hear opinions or options from other experts!

Colin

Furring Strips For Radiant Barrier


Radiant barrier just need an airspace to work properly. There are no minimums on the actually depth of that air space as long as there is no contact or interference with the venting of the roof if you are going for that option.
