The basics
Three levers fix a hot attic: insulation (R-value) resists heat flow, a radiant barrier reflects radiant heat, and ventilation moves hot, moist air out.
- Insulation (R-value): Higher R-value resists heat flow; many older Houston attics are under-insulated. [GATHER: recommended attic R-value for the region.]
- Radiant barrier: A reflective layer that blocks radiant heat gain — high impact in a hot, sunny climate.
- Ventilation: Balanced intake/exhaust prevents heat and moisture buildup (mold risk).

Your options
Which attic upgrade pays off first?
Add insulation
Usually the highest-ROI first step if you're under-insulated.
Radiant barrier
Strong addition in our sunny climate; pairs well with insulation.
Ventilation
Essential for moisture/heat control; often done alongside the above.
Blown-in vs. batt
Blown-in fills gaps in existing attics well; batts suit open framing.
Honest trade-off: the best mix depends on your current R-value and attic — we measure before recommending.
