Types of Roof Insulation Materials We Offer

When choosing roof insulation for your commercial flat roof, it’s important to consider durability, energy efficiency, and compatibility with your roofing system. Different materials offer various benefits like moisture resistance, thermal performance, and ease of installation.

Polyisocyanurate

Polyisocyanurate, or polyiso, is a popular insulation board used for commercial flat roofs. It has a high R-value per inch, which means it provides strong thermal resistance and helps keep your building energy efficient.


Polyiso boards are lightweight and rigid, making installation faster and easier. They resist moisture well, so they don’t lose insulating power if exposed to damp conditions. This makes them ideal for roofs in wet climates or flat roofs with drainage challenges.


We use polyiso boards for insulation in many projects because they balance cost, performance, and ease of handling. They also work well under roofing membranes like TPO or PVC, commonly found on flat commercial roofs.

Expanded Polystyrene (EPS)

Expanded polystyrene (EPS) is a foam insulation material made from small beads fused together. It’s affordable and provides good insulation value. EPS is lighter than some other boards but has a slightly lower R-value per inch.


One advantage of EPS is its resistance to water absorption. It can handle exposure to moisture better than some foams, which helps maintain insulation performance over time.


EPS is used in commercial roofing when budget considerations are important and a moisture-resistant option is needed. It also works well in roof systems where the insulation is covered immediately by other layers.

Extruded Polystyrene (XPS)

Extruded polystyrene (XPS) is a denser and stronger insulation board compared to EPS. It offers higher compressive strength, which makes it suitable for roofs that may experience foot traffic or heavy equipment placement.


XPS is also water resistant and maintains consistent R-values even when exposed to moisture. This protect your building’s energy efficiency and roof lifespan.


Because of its toughness and moisture resistance, XPS is great for commercial flat roofs where durability is a priority. We recommend XPS when roof conditions require both strength and reliable insulation value over time.

Our Commercial Roof Insulation  Installation Process

We focus on delivering tailored insulation solutions that improve your building’s energy efficiency and protect your roof structure. Our process includes a detailed evaluation of your current roofing system, customized material selection, precise installation, and thorough inspections to guarantee lasting performance.

1. Assessment and Consultation

We begin by examining the specific conditions of your commercial roof. This includes checking the current insulation, moisture levels, and the overall roof structure. We also consider your building’s energy needs and local climate to recommend the best insulation options.  We also discuss your goals, budget, and any potential challenges. This helps us create a plan that fits your unique situation. Our team inspects for leaks, damage, and gaps that reduce insulation effectiveness. We provide a clear report outlining our findings and suggested solutions, so you know exactly what to expect before work begins.

2. Custom Insulation Solutions

We design insulation systems to match your building’s requirements. We use materials like polyisocyanurate, foam boards, or reflective coatings depending on what suits your roof type and energy goals best. Our choices focus on improving thermal resistance, moisture control, and durability. We balance cost-effectiveness with long-term benefits to give you solid value. You can expect insulation that helps lower heating and cooling costs while protecting your roof against weather and wear. We tailor thickness and layering to optimize performance based on your building’s design and usage.

3. Installation Process

Our trained crew follows a step-by-step process to install your roof insulation correctly and safely. We start by preparing the roof, which includes cleaning and repairing any damage found in our assessment. Next, we apply the insulation material according to best industry practices. This may involve adhering foam boards, spraying foam insulation, or laying membranes depending on the chosen system. We seal all joints and edges carefully to prevent air leaks and water intrusion. Throughout installation, we prioritize minimizing disruption to your business operations. Our team works efficiently while maintaining high safety standards.

Quality Assurance and Inspection

Once installation is complete, we perform a detailed inspection to verify that everything meets our quality standards. We check for secure adhesion, proper sealing, and consistent insulation coverage. Our quality assurance includes moisture testing and thermal imaging when needed to confirm the insulation is effective and without gaps. We document these findings in a report for your records. If any issues arise during inspection, we address them promptly before project closeout. We also provide guidelines on how to maintain your roof insulation to keep it working well for years.

Insulation Installation Best Practices

When installing commercial roof insulation, attention to detail is key to ensure durability, energy efficiency, and compliance. Proper steps include following local codes, controlling moisture, and making sure the insulation works well with the roofing system.

Meeting Local Building Codes

We always start by checking your local building codes. These rules set minimum standards for insulation materials, thickness, and fire resistance. Meeting these standards isn’t optional. It keeps your building safe and can affect insurance or future inspections.



Our team verifies requirements like R-value minimums and installation methods specific to your area. We ensure all materials are approved and installed according to guidelines. This reduces the risk of costly repairs or code violations later.

Vapor Barriers and Moisture Control

Moisture control is critical for roof insulation. Without it, water can get trapped and cause mold, rot, or reduced insulation performance. We install vapor barriers where needed to block moisture from entering the insulation.


These barriers prevent condensation build-up and protect the roofing layers. We choose the right type of vapor barrier based on your climate and roof design. Proper sealing around seams and edges is essential to keep moisture out.

Seamless Integration With Roofing Systems

Insulation must fit perfectly with your roofing materials to work properly. We coordinate with your roofing contractor or handle both tasks ourselves. This prevents gaps and weak points in the roof assembly.



We use fastening techniques and insulation boards designed for commercial flat roofs. That ensures the insulation stays secure and maintains its thermal properties. Proper integration also helps improve the roof’s lifespan and energy savings.

Maintenance and Long-Term Performance

Proper care of your commercial roof insulation helps maintain energy efficiency and extends the roof’s lifespan. Regular checks and timely repairs keep insulation effective and prevent costly problems later. Understanding when and how to manage repairs can save you money and headaches.

Routine Inspections

We recommend scheduling routine inspections at least twice a year, ideally in spring and fall. During these inspections, we look for signs of water damage, insulation compression, and any gaps that may let air escape. We also check for loose or missing roofing materials that can expose insulation to the elements.



Our team uses moisture meters and thermal imaging to detect hidden issues under the roof surface. This helps us catch problems early before they cause serious damage. Keeping insulation dry and intact supports your building’s energy performance and reduces heating and cooling costs.

Repair and Replacement Recommendations

When damage or wear is found, we advise addressing it quickly to avoid bigger repairs. For minor insulation issues, spot repairs or adding insulation patches can restore function. If large areas are affected or the insulation shows signs of long-term degradation, full replacement may be necessary.



We also consider the roof’s age, material type, and previous repairs in our recommendations. Replacing damaged insulation along with the roof membrane often offers the best protection and energy savings. Our goal is to help you make informed decisions that fit your budget and building needs.
