will add an R value of 5

That's between the 4x6s.

Interestingly, the 4x6s alone have an R value of 6.88.

How about adding insulation to the walls?

If you add insulation to the roof, consider going up to the Energy Star recommended R25-R38 for southern California.

But before adding any insulation, tighten up the house. Loss of heated air through cracks, chimneys, vents and the like can account for 16% of heat loss.

NOTES:

Very Nice Tip!!
Check out your house for any cracks or vents
