Radiant Barrier Installation & Repair
Most of the heat that loads up a Florida attic comes in as radiant energy off the hot roof deck — and ordinary insulation does not stop that, it only slows the heat once it is already inside. A radiant barrier is a reflective layer that blocks that radiant heat before it ever reaches your insulation. P1Mitigators™ coordinates radiant barrier installation and repairs across Jacksonville and Duval County.
We coordinate reflective foil radiant barrier stapled to the underside of the roof deck and rafters, so it reflects the roof heat back out instead of letting it soak into your attic. On the right home it can drop attic temperatures noticeably and take real strain off the AC — and it works even harder when paired with attic fans and good insulation.
We also repair sagging, torn, or improperly installed radiant barrier that has come loose over time or after roof work. Because we coordinate the whole attic envelope, we can combine a radiant barrier with an insulation top-up and attic ventilation for the biggest drop in your cooling bill.

Frequently Asked Questions
What does a radiant barrier actually do?
It is a reflective layer, usually foil, installed under the roof deck. The sun heats your roof, and that heat radiates into the attic — a radiant barrier reflects most of that radiant heat back out before it ever reaches your insulation or your ceiling. Regular insulation only slows heat that is already inside; a radiant barrier stops a lot of it from getting in.
Is a radiant barrier better than more insulation?
They do different jobs and work best together. A radiant barrier blocks radiant heat coming off the roof; insulation slows the heat that does get in. In a hot Florida attic, the biggest wins usually come from doing both plus ventilation. We tell you which is the smarter first dollar for your attic.
Can you repair a radiant barrier that has fallen down?
Yes. Foil that has sagged, torn, or come loose — often after roof or HVAC work — can be re-secured or replaced. We inspect it and get it doing its job again.
Who does the installation?
P1Mitigators™ coordinates and manages the project; the barrier is installed by vetted attic and roofing crews so it is secured correctly and does not interfere with your ventilation.
