Is Roof Insulation Really That Important?
Absolutely. At Kore Roofing, we know that roof insulation is one of the most overlooked — yet most impactful — parts of your roofing system. Proper insulation keeps your home warm in winter, cool in summer, and energy-efficient year-round, all while protecting against moisture and noise.
How Roof Insulation Works
Roof insulation reduces heat transfer between your home’s interior and the outdoors by blocking three main pathways:
-
Conduction: Stops heat from moving directly through roofing materials.
-
Convection: Prevents warm or cool air from escaping through gaps.
-
Radiation: Reflects radiant heat away from your home to keep indoor temps stable.
Types of Roof Insulation and Their Benefits
| Type | Description | Best For |
|---|---|---|
| Fiberglass Batts | Spun glass fibers with high R-value | Affordable, easy installation |
| Foam Boards | Rigid panels with high moisture resistance | Space-limited areas, durability |
| Spray Foam | Expands to fill gaps, creating an airtight seal | Superior insulation and air sealing |
| Radiant Barrier | Reflects radiant heat away from the home | Hot climates like Arizona |
