As a building inspector for the Boston area I can tell you this is a building code violation if the Contractor uses only blown cellulose in the rafter bays. (From what "Joe Bloggs" claims.) Expanding spray foam or foam board must account for at least 40% of the R-value in each rafter bay. 8th Residential code section 8.00 Roof Ceiling Construction for the state of Massachusetts.
