Central San Diego sits between coastal humidity and inland heat. Lemon Grove attics typically hold 1980s or older insulation that has settled to R-15 or worse. Going to R-49 cellulose plus air-sealing is the standard upgrade and pays back in 3–5 years on cooling.. Central San Diego radiant barrier helps on south-facing roofs in older San Diego and La Mesa homes with attic ducts.

No. Radiant barrier handles the radiant component of attic heat. Insulation handles the conductive component. Each does a different job. In a hot inland attic the combination is what matters — barrier on the rafters, insulation on the floor.

Less than inland. Coastal homes — Encinitas, Carlsbad, Imperial Beach — usually do not see attic temps high enough to make radiant barrier the highest-return move. We will tell you whether to skip it on the coast.
