Insulation in Tampa: What You Need to Know
In Tampa's hot climate, attic insulation is the single highest-impact upgrade. Heat pours through an under-insulated attic ceiling, forcing your AC to work harder. The DOE recommends R-38 to R-49 for most FL attics, with radiant barriers adding further benefit in extreme heat. Bringing a 1,500 sq ft attic from R-11 to R-49 typically costs $1,200–$2,400 and pays back in 3–6 years.
