Roof insulation helps keep your home warm in winter and cool in summer by reducing heat loss. It’s different from attic insulation, which is placed in the ceiling of the attic. Roof insulation is applied directly to the roof structure, which can help prevent issues like ice dams and moisture problems, especially if you have a flat or pitched roof.

Key Takeaways
– Average Cost: Roof insulation usually costs between $1,000 and $2,500, with most projects averaging around $2,000.
– Material Impact: The cost varies with the material. Fiberglass is the cheapest, while spray foam is the most expensive but offers better insulation.
– DIY vs. Professional: DIY installation can save money, especially with fiberglass or rigid foam, but spray foam usually requires professional installation.
Roof Insulation Costs
Fiberglass Batt/Roll – $0.30 – $1.50
Blown-in/Loose Fill – $1 – $2
Spray Foam – $0.50 – $2
Radiant Barrier – $0.20 – $1
Rigid Foam – $0.25 – $1
Spray foam insulation often needs a contractor, and radiant barriers don’t usually provide an R-value, though they might help with heat retention and act as a vapor barrier.
Is Roof Insulation Worth It?
Insulating a roof is crucial under certain conditions:
– Ice Dams: It prevents ice dams, which occur when ice forms on the roof due to water refreezing. Ice dams can cause severe roof damage.
– Climate Control: In homes with slab-on-grade foundations, insulation helps keep the house cooler in warmer climates by managing air conditioning effectively.
Converting an Attic
If you plan to convert an attic into a living space, roof insulation will help manage temperature fluctuations typical in attics.
What Is R-Value?
R-value measures the insulation’s effectiveness. Higher R-values mean better insulation. Different climates require different R-values and higher R-values generally cost more.
Insulation Costs by Roof Type
– Pitched Roof: Insulating sloped roofs cost between $0.50 and $1.50 per square foot, with installation adding $2 to $2.50 per square foot.
– Flat Roof: Insulating a flat roof typically costs about $0.67 per square foot for a 1-inch thick PolyISO with an R-value of six. The cost increases with thicker insulation boards.
DIY vs. Professional Installation
You can choose between DIY and professional installation:
– DIY: If you’re skilled and have the right tools, DIY insulation can save money.
– Professional: For complex installations, like spray foam, hiring a professional ensures proper installation and safety.
In summary, the cost of roof insulation depends on the type of insulation, the area to be covered, and whether you choose DIY or professional installation. Consider your home’s specific needs and your budget to make the best decision.
