Business owners in Columbus, OH, often face challenges when maintaining their buildings’ energy efficiency, especially when it comes to roof insulation. A common question is: Can new insulation go over old insulation in commercial buildings? With evolving technologies in commercial roof insulation, it’s a great opportunity to address this question while also considering ways to improve energy savings and comfort.
In this blog, we’ll explore whether layering new insulation is a viable solution for your commercial building in Columbus, OH, and the important factors to consider. If you need expert guidance, our insulation service in Columbus, OH, can help assess your building’s unique needs.
The Challenges of Commercial Roof Insulation
Before answering whether new insulation can go over old insulation, let’s examine some of the key issues many Columbus building owners face with their commercial roof insulation. Over time, insulation tends to degrade, and this can result in several problems.
Energy Inefficiency
One of the most apparent signs of failing insulation is energy inefficiency. If you’ve noticed inconsistent indoor temperatures or rising energy costs, it’s likely your insulation is underperforming. Old or insufficient insulation can cause significant energy loss, leading to higher heating and cooling expenses.
Moisture Problems
Moisture can be a major concern in older buildings. If your insulation has been exposed to leaks or condensation, it may be holding moisture, reducing its effectiveness and even contributing to mold growth. Proper insulation should act as a barrier to prevent water damage and preserve the integrity of your commercial building.
Aging Materials
In older buildings, insulation materials may have broken down over time, causing reduced performance. Aging insulation can also become compressed or damaged, leaving your building vulnerable to heat loss and moisture.
Can New Insulation Go Over Old Insulation?
The good news is that, in many cases, new insulation can be installed over old insulation in commercial buildings. However, there are some important factors to consider before deciding whether this approach is right for you.
Benefits of Installing New Insulation Over Old
Layering new insulation on top of the existing material offers several advantages for commercial buildings in Columbus, OH:
Cost Savings: Removing old insulation can be expensive and time-consuming. By leaving the existing material in place and adding a new layer, you can save on labor costs and material disposal.
Improved Energy Efficiency: Adding more insulation increases the overall R-value, which improves your building’s ability to retain heat in the winter and keep cool air in during the summer. This leads to lower energy costs and a more comfortable indoor environment.
Less Disruption: Since the old insulation doesn’t need to be removed, the project can be completed faster, causing minimal interruption to your business operations.
Important Considerations
While adding new insulation over old has its benefits, it’s not always the right solution. A thorough assessment of your building is necessary to ensure the old insulation is in suitable condition. Here are key factors to consider:
Moisture: Any moisture trapped in the existing insulation can lead to mold growth and structural damage. It’s important to make sure the old insulation is completely dry before layering new insulation on top.
Compatibility of Insulation Types: Not all types of insulation work well together. Some materials may cause chemical reactions, leading to reduced performance or potential hazards. A professional can help you choose the right insulation types for compatibility.
Structural Support: Adding new insulation increases the weight of your roof structure. A professional inspection can help determine whether your roof can safely support the additional load.
Types of Commercial Roof Insulation for Layering
Understanding which types of insulation can be layered is essential. Not all insulation materials are compatible with each other, so selecting the right one for your commercial roof is crucial.
Rigid Board Insulation
Rigid board insulation is a popular choice for commercial roofing in Columbus, OH. It offers a high R-value and durability, making it ideal for layering. It’s also moisture-resistant, which adds extra protection to your roof.
Spray Foam Insulation
Spray foam insulation is another highly effective option, but it may not always be ideal for layering over existing insulation. Spray foam needs to adhere directly to the surface, and applying it over old insulation could reduce its bonding strength.
Blown-In Insulation
Blown-in insulation can be a great choice for adding insulation in hard-to-reach areas of a commercial roof. It can fill gaps that other types of insulation may miss, but it’s important to ensure the old insulation isn’t compressed to maintain effectiveness.
Professional Assessment Is Key
Before installing new insulation over old in a commercial building, it’s critical to have a professional inspection. Here’s why:
Structural Soundness: A professional will determine if your roof structure can support the added weight of new insulation layers.
Moisture Check: Hidden moisture can cause problems down the road, like mold or decay. Professionals have tools to detect moisture that may not be visible.
Code Compliance: Building codes in Columbus, OH, may specify insulation requirements. Professionals ensure your project meets all local regulations.

Energy Efficiency and Long-Term Savings
Investing in new commercial roof insulation is an investment in the long-term health of your building. Here’s how proper insulation can benefit you over time:
Lower Energy Costs: Better insulation means your building will require less heating and cooling, which translates to lower energy bills.
Extended Roof Life: Proper insulation can protect your roof from extreme temperatures, preventing wear and tear and extending its lifespan.
Enhanced Comfort: Consistent temperatures within the building create a more comfortable environment for employees and customers.
According to the U.S. Department of Energy, buildings with sufficient insulation reduce energy consumption by up to 20%, underscoring the importance of having an efficient insulation system in place.
Additionally, the National Institute of Building Sciences highlights the importance of proper insulation in commercial buildings, especially for long-term cost savings and enhancing the overall energy performance of structures.
