Our TPO Roof Installation Process

We follow a precise and thorough process to ensure every TPO roof installation meets the highest standards. From initial evaluation to final quality checks, our approach focuses on durability, energy efficiency, and long-term performance tailored specifically for commercial and industrial buildings.

Initial Consultation and Evaluation

We begin by assessing your roof’s current condition and understanding your specific needs. This includes inspecting the roof deck for structural soundness, existing materials, and any damage or moisture issues. We also review building specifications and local codes to ensure compliance.



Our team discusses your energy efficiency goals and budget to recommend the appropriate insulation and TPO membrane thickness. This step is crucial to customize the roofing system to your property's unique requirements, avoiding unnecessary costs or future problems.

Preparation and Surface Inspection

Preparation starts with thorough cleaning and removal of any debris or old roofing materials that might impair adhesion and welding. We repair or reinforce the roof deck to establish a stable, flat surface critical for a successful TPO membrane application.



We then install insulation boards, commonly polyisocyanurate or polystyrene, securely fastening them without gaps. Proper insulation placement enhances the roof's thermal performance and support, setting the foundation for the TPO installation.

Installation Techniques and Quality Assurance

We carefully unroll and lay the TPO membrane, maintaining proper overlap between sheets for effective heat welding. Using hot-air welding equipment, we fuse the seams continuously to prevent leaks and ensure a watertight seal.



All roof penetrations receive pre-formed TPO flashing, securely welded to prevent water infiltration. Edge flashings are installed and sealed to protect membrane edges. Finally, we conduct a detailed inspection of welds, seams, and flashing to verify strength and durability before project completion.

Benefits of TPO Roofing for Commercial Properties

TPO roofing provides measurable advantages for commercial buildings, especially when considering long-term performance and operational costs. Its qualities directly impact energy management, structural durability, and sustainability practices—key areas for any commercial or industrial property owner.

Energy Efficiency and Cost Savings

TPO roofing's highly reflective white surface helps reduce heat absorption on flat or low-slope roofs. This reflectivity lowers rooftop temperatures, which in turn decreases the cooling load for commercial HVAC systems.



By limiting heat buildup, TPO roofing can reduce energy bills significantly, especially during hot summer months. This makes TPO a practical choice for businesses aiming to cut operational costs without compromising comfort inside the building.

Durability and Weather Resistance

We rely on TPO roofing because of its resilience against common commercial roofing challenges. It resists UV radiation, ozone exposure, and chemical damage, which are frequent concerns for industrial sites.



TPO membranes are also resistant to punctures and tears, helping maintain the roof’s integrity even in harsh weather conditions like wind, rain, or hail. This durability translates to fewer repairs and extended roof lifespan.

TPO's Environmental Advantages

TPO roofing supports environmentally responsible building practices. Its energy-saving properties reduce greenhouse gas emissions linked to air conditioning use in commercial buildings.



The material is often recyclable, and its manufacturing process generally involves fewer harmful chemicals compared to alternative roofing membranes. This lowers the overall environmental footprint.

TPO Roofing Installation FAQs

  • What is the cost per square foot for TPO roofing installation on commercial buildings?

    TPO roofing installation typically costs $7-$11 per square foot for commercial buildings, depending on project complexity and existing roof conditions. This pricing includes tear-off of existing materials, ISO insulation, substrate preparation, and Carlisle or GAF TPO membrane installation. Factors affecting cost include roof accessibility, number of penetrations, and insulation requirements. Large projects over 20,000 square feet may qualify for reduced per-square-foot pricing.

  • How long does TPO commercial roofing typically last in Midwest climate conditions?

    Quality TPO roofing systems typically last 20-25 years in Midwest climate conditions when properly installed and maintained. Our heavy-duty TPO membranes are engineered to withstand extreme temperature fluctuations from -40°F to 110°F, making them ideal for northern Illinois weather patterns. Premium systems from manufacturers like Versico and Firestone feature enhanced UV stabilizers that resist degradation from intense summer sun while maintaining flexibility during freeze-thaw cycles.

  • What are the energy-saving benefits of TPO roofing for commercial properties?

    TPO's highly reflective white surface typically reduces cooling costs by 20-30% during summer months by reflecting up to 85% of solar radiation. ENERGY STAR rated TPO membranes maintain reflectivity ratings above 0.70 after three years of weathering, significantly outperforming traditional roofing materials. This reflectivity reduces urban heat island effect and lowers indoor temperatures by 6-8°F, decreasing HVAC runtime and extending equipment lifespan. Many buildings achieve payback through energy savings within 3-5 years.

  • How does TPO roofing compare to EPDM or modified bitumen for flat commercial roofs?

    TPO offers several advantages over EPDM and modified bitumen: superior energy efficiency through higher reflectivity (TPO: 85% vs. EPDM: 5-30%), lower installation costs than modified bitumen, and heat-welded seams that outperform EPDM's adhesive seams in watertightness. TPO provides excellent puncture resistance while offering flexibility similar to EPDM. While EPDM has slightly longer potential lifespan (25-30 years), TPO delivers better overall value through energy savings and competitive installation costs for most commercial applications.

  • What thickness of TPO membrane is recommended for commercial buildings in Joliet?

    For Joliet commercial buildings, we recommend minimum 60-mil TPO membrane thickness to withstand local weather conditions and provide optimal service life. High-traffic roofs or buildings with extensive mechanical equipment should consider 80-mil membranes for enhanced puncture resistance. The additional material cost of thicker membranes (approximately $0.50-$0.75/sq ft) is justified through extended service life and reduced maintenance expenses.
