Rigid Insulation in Colorado: Understanding Your Home’s R-Value
When homeowners think about roofing, they often picture shingles, tiles, and gutters. However, one of the most important components of a roofing system is hidden beneath the surface: the rigid insulation (RI). This is the material that helps minimize how much heat your home loses in the winter. If you have found yourself overpaying for heating, the problem may be poor insulation in your home.
What Is Rigid Insulation?
Rigid insulation, sometimes called foam board insulation, consists of dense, durable panels used to create a continuous thermal barrier within a roofing system. These panels are made of a material called Isocyanate, which is a type of open-celled foam. Each panel has three parts: Various thicknesses ISO, 1 inch of air space, and 7/16 inch of plywood.
If you have a home with vaulted ceilings, you typically have 2 options for adding insulation to your home: the first is to do it from the inside where you tear out the drywall and put more insulation in the rafters. The second way is from the outside; this can only be installed during a roof replacement. Before the new roofing system is put on, the contractor will install the RI panels over the existing plywood or planking.
While this process will increase the overall cost of your roof replacement, it is worth it for the added protection and energy efficiency of your home. The investment usually pays for itself in the form of resale value and money saved on heating and cooling.
What Is R-Value?
The term R-value measures a material’s resistance to heat flow. Simply put, the higher the R-value, the better the insulation prevents heat from escaping or entering the building. R-value is determined by:
Material composition
Thickness
Density
In Evergreen, Colorado, building code requires structures to have at least a R30; however, regional recommendations suggest that Colorado homes should have an R49 to R60 because of our cold climate.
Why Rigid Insulation in Colorado: Why It Matters
Rigid insulation offers unique advantages that make it a cornerstone of modern roofing systems. Here’s 4 reasons why added insulation is beneficial for homeowners in Evergreen, Colorado:
1. Superior Thermal Performance
Rigid insulation provides a continuous layer of thermal protection that reduces energy transfer between the inside and outside of the building. Unlike batt insulation, which can sag or leave gaps, rigid insulation creates a consistent barrier that retains its shape over time.
2. Improved Energy Efficiency
High-quality rigid insulation helps maintain stable indoor temperatures. This reduces strain on heating and cooling systems and can significantly lower monthly utility bills. Homeowners often see noticeable improvements in comfort, especially in extreme climates.
3. Moisture and Condensation Control
Certain types of rigid insulation offer excellent moisture resistance. When installed correctly, they reduce the likelihood of:
Condensation
Mold growth
Rot
Water infiltration
4. Long-Term Cost Savings
While rigid insulation in Colorado may cost more upfront than other insulation types, it pays for itself through:
Reduced energy consumption
Fewer repairs
Extended roof lifespan
Increased property value
For many homeowners, upgrading insulation is one of the wisest investments in the entire roofing process.
Choosing the Right R-Value for Your Roof
Selecting the correct R-value depends on several factors, including climate, roof design, and building code requirements. Here’s what homeowners should know when making this decision:
Climate Zone Matters
Colder regions require higher R-values to prevent heat loss, while warmer climates benefit from R-values that limit solar heat absorption. Building codes in many areas specify minimum insulation requirements based on climate zones. Troost Roofing can help determine the appropriate R-value for your location.
Roof Type Influences Insulation Needs
Flat and low-slope roofs typically require higher R-values because they are more exposed to temperature changes.
Pitched roofs may use a combination of rigid insulation and other types of insulation depending on attic ventilation and design.
Thickness Equals Performance
Because rigid insulation’s R-value increases with thickness, the total height of the insulation layer must be controlled carefully during installation. When Troost Roofing installs rigid insulation in Colorado, our team is diligent to ensure that added insulation does not interfere with:
Flashing
Roof edges
Ventilation
Drainage

How Rigid Insulation in Colorado Improves Roof Longevity
A well-insulated roof does more than regulate temperature—it protects the entire roofing system. Here’s how:
Reduces Thermal Shock
Daily temperature swings cause roofing materials to expand and contract. Over time, this can lead to cracking, warping, or premature failure. Rigid insulation helps moderate these temperature changes, reducing stress on roofing materials.
Minimizes Ice Dams
When heat escapes a house via the roof, it causes a conversion of snow to ice during the winter. This occurs because of the freeze/thaw cycle: after snow falls and gathers on the roof, it is melted by heat from the home, then that water reaches the eaves, which is unheated, and freezes into ice. Over time, these ice dams prevent water from being able to reach the gutters and drain into the yard. That water is forced into the roofing system and can permeate the home.
Why Professional Installation Matters
Even the highest-quality rigid insulation cannot perform properly without expert installation. A skilled roofing contractor ensures:
Precise cutting and fitting of insulation boards
Correct staggering of seams
Proper fastening or adhesive application
Integration with ventilation systems
Compatible roofing membranes and materials
Compliance with building codes and manufacturer specifications
Poor installation can lead to gaps, air leaks, trapped moisture, or compromised structural integrity, which could necessitate a roof repair down the line. Troost Roofing uses industry-standard techniques to maximize insulation performance and maintain warranty coverage.
