Blown-in Insulation

Categories: Insulation

Does anyone know about blowing in insulation into closed walls and flat roof? House is 17′ X 44′. The top floor is freezing in winter and boiling in the summer. Any recommendations on a company that can do this? Is cellulose good? Should vents be installed in the roof? Please advise.
