4.3.4 Gathering Additional Information
After calling several contractors, I found that the cheapest quote came in at $650. For installing insulation, the instructions recommend wearing safety glasses, a face mask, and gloves (an additional $45 altogether).
The insulation has to be fitted between the joists, which connect to the frame of the roof that is four inches wide around the edges and will not be covered by insulation. Fortunately, a quick check in the attic shows that there are 17 joists and the insulation fits perfectly between them.
