Under the Florida Building Code, Miami-Dade County homes require a minimum R-30 attic insulation. This is especially important if you have an unfinished basement or one that is always cold and drafty. Adding insulation will improve its ability to retain heat and protect it from moisture, mold, mildew, and pests. The effectiveness of an insulating wall or roof also depends on how and where the insulation is installed.
Roof insulation materials must have a minimum of R-30. The choice of insulation depends on the space you have, the apparent density of the materials, ease of access to space, budget, how easy it would be to replace the insulation if you had a leaking roof or wall, and whether you are building a new house or upgrading an existing one. When insulating folding staircases, prefabricated or site-built, insulating and waterproofed roofs are recommended.

Insulation in the attic is critical because it passes more heat per square foot through the roof than any other structure in a house. Attic insulation is South Florida's first line of defense against heat, and proper installation can reduce utility bills, keep the house clean, and ensure an even temperature throughout the house.
