Many ways to lower solar heat transference rate to attic or ceiling spaces. Trick is doing it cheaply enough to recover the investment.

This looks like a simple fix compared to others I could tell you about.



Go for it.

That's exactly it. Or, at least one of the lines our builder introduced to us. The other is by Owens COrning, but same idea. Apparently, here in LA we have no choice--ithe building code mandates we install a cool roof. We'll install attic insulation, as well, and we're also re-engineering the flat portion of our roof (which is mostly pitched, with the exception of our family room), to include insulation also.

I was just wondering if what I've read is all marketing hype, or if it really makes a difference in this hot, dry climate.
