Ultimately selecting which product and value to use depends on many factors - particularly thermal load; regardless, ASHRAE's new above-deck roof insulation standard is a good place to start, as it jumped 33 percent, from R-15 to R-20, in five of six climatic regions.
2014 POLYISO INSULATION LTTR R-VALUES TECHNICAL DATA BULLETIN SecurShield CD SecurShield CD is a rigid roof insulation panel composed of a closed-cell polyisocyanurate foam core manufactured on-line to an enhanced coated glass facer on each surface side to achieve greater ﬁ re resistance over wood decks. † Size: 4' x 8' † Thickness: 1"
Here is a rough, back-of-the-envelope calculation: you have increased the thickness of your between-the-studs insulation by 32%, so you also have to increase the minimum R-value of your exterior foam by 32% -- in other words, from R-15 to R-20.
The average cost of flat roof insulation is $0.67 per square foot (for 1 inch thick PolyISO with 6-R value).. High quality rigid foam insulation that is properly installed will greatly improve ventilation, eliminate drastic temperature fluctuations inside the home, and protect from leaks.
