| Jan 5 at 18:59 | comment | added | isherwood | R49 seems an unreasonable goal for a rafter roof. While that's a modern standard, it usually involves roof systems designed with capacity for it in mind. If you can get to R-30 or a bit more you're in a good place, considering your relatively mild climate. Of much greater concern are air leaks elsewhere in the home. | |
