Asbestos on flat roof top

[Michael P.]

Hi All.  Asbestos survey confirmed asbestos on existing roof materials.  I want to properly remove it and am wondering what the scope entails and what might be a reasonable cost for the removal.  

Also, I need to put a "temporary" roof because the house will undergo a gut renovation and expansion including adding a floor.  You may ask, why not wait till you do the entire gut, but my consultants suggest that an interim step of abatement and a temporary rooftop allows for the permitting process to be smoother with a clean asbestos survey.  

any thoughts?
