Re-roofing and insulation sequence
If we are going to re-roof the house and add the blown-in insulation (currently, none), should we do that before the shingles or after? or, it doesn’t matter?
The house is in CA. I asked because I thought they would do that after the old shingles were removed and before the new shingles were installed. I called the office and the project coordinator told me that I didn’t order the insulation. I called the sales rep and he told me that it didn’t matter and the roofer would install the shingles and insulation would be blown later. However, when the insulation company called and asked to gain access from the house so that they could blow the insulation to the attic, I told her that there were no access. I told her that if they needed to punch a hole or use the vent to access the attic, they must put everything back in good condition. Then, I don’t know why the roof company didn’t put the new shingles. After the insulation was blown, the roof company said it was ME who requested to have the insulation first and their crews were busy working in other sites.
