We recently had a severe hail storm which totaled our roof.
I was unaware of radiant barrier and it’s benefits when we built the home in 1999. In the past few years I have struggled to keep the house cool in during the summer months without ridiculous bills. I have somewhat reduced by adding additional insulation and installing 2 thermostatic attic fans.
I have thought of adding some sort of radiant barrier over the past year or so, but the areas that need it most do not have accessible attic space.
My questions are:
Since they are pulling of the composition roof, should is it better to go ahead and have the roof re-decked with a radiant barrier decking? If I don’t do it now, I will only have the option of spray on type or retrofit type. Further, there are 3 areas that are not common to the main attic, so I would have to cut a hole in the ceiling to gain access for retrofit.
Will adding ridge vents to the main attic space short circuit the effectiveness of the powered fans?
Should I consider adding ridge vents to the areas of the of the roof that do not have accessible attic space (no benefit from powered pan)?
Thanks in advance.
