Complete Roof Insulation Guide
Your roof’s insulation is one of the most important aspects of your roofing system, as it promotes energy efficiency and ensures your indoor space remains comfortable. But which type of roof insulation is best for your specific needs?
In this blog post, the roofing experts at Schoenherr Roofing provide a comprehensive guide to different roof insulation types so you can make the most informed decision for your property.
What Is Roof Insulation?
Roof insulation is installed in your roofing system to provide a protective barrier between the attic and the outdoors. Adequate roof insulation helps minimize thermal transfer, maintaining consistent comfort indoors and reducing reliance on HVAC systems. This results in greater energy efficiency and lower utility costs.
Proper roof insulation can also help prevent moisture buildup and condensation, which can lead to significant structural damage such as wood rot or mold and mildew growth over time. Roof insulation plays a pivotal role in enhancing energy efficiency, increasing home comfort, and protecting the structural integrity of your property.
Common Types of Roof Insulation
There are several different types of roof insulation to choose from, the most common being:
Spray Foam Insulation
Spray foam insulation is an excellent material choice. With a higher R-value compared to other roof insulation materials, spray foam insulation offers superior soundproofing and resistance to air and moisture infiltration, especially when using open-cell foam.
One potential drawback of spray foam insulation is the higher price. And while it’s moisture-resistant, spray foam insulation can be prone to water absorption, which may increase the likelihood of mold and mildew growth.
Structural Insulated Panels
Another option for homeowners to consider is structural insulated panels, which are factory-produced foam panels that are layered between your roofing system. These offer continuous insulation and incredible protection against thermal transfer and moisture infiltration.
When properly ventilated and sealed, these panels can help improve indoor air quality while strengthening your roof’s structural integrity. While insulated panels can resist moisture, they have the potential for water retention and damage if improperly installed.
Rigid Insulation Boards
Also referred to as foam board insulation, rigid insulation boards are created from a variety of materials, including high-density polyisocyanurate. These boards offer a higher R-value than other insulation materials, featuring greater thermal resistance as a result.
They’re also fire-, moisture-, and mold-resistant, making them an excellent choice for protecting the structural integrity and safety of your roofing system.
Despite their superior resistance to fire, moisture, and mold, insulation boards can be more vulnerable to bug infestations. They’re also not as effective in temperatures below 50º F.
Fiberglass Batt Insulation
Created from small glass particles woven into coarse fabric, fiberglass batt insulation is a great choice, especially for those who wish to DIY their roof insulation. Available in standardized sizes and easy to install, fiberglass batt insulation offers a higher R-value per inch than blown-in fiberglass options.
While you can DIY batt insulation installation, it’s important to note that this material can release hazardous fibers into the air, which can be dangerous to your health if inhaled. Thicker batts may also limit your ability to layer insulation, potentially reducing your thermal protection.
Blown-In Roof Insulation
Commonly used in attics and wall cavities, blown-in insulation offers a great solution for retrofitting existing roof insulation. Easy to install over existing insulation, blown-in materials can increase your R-value, offering effective protection against heat transfer and enhanced energy efficiency.
Once again, it’s important to trust a professional with your installation needs, as fiberglass materials can be incredibly harmful to your health if inhaled.
