Single-Ply TPO & EPDM Roofing Systems

Selecting the right single-ply roof membrane is one of the most important decisions you can make for your commercial or industrial facility. Both TPO (Thermoplastic Olefin) and EPDM (Ethylene Propylene Diene Monomer) deliver exceptional durability and weather resistance, but each material excels under specific operational conditions. At NIJAC Roofing & Insulation, we specialize in the professional installation, replacement, and maintenance of high-performance TPO and EPDM roofing systems across the Midwest.

Our team evaluates your facility’s energy requirements, rooftop equipment exposure, and structural layout to design a single-ply system that maximizes longevity and lowers lifetime operational costs.

TPO Roofing Systems

TPO is a bright white, single-ply thermoplastic membrane highly valued for its solar reflectivity and thermal performance.

• Energy Cost Reduction: TPO reflects up to 80% of solar radiation away from your building envelope, significantly lowering peak summer cooling loads and easing demand on commercial HVAC units.
• Heat-Welded Seams: TPO sheets are fused together using hot-air welding equipment, creating seamless lap joints that are stronger than the membrane itself.
• Chemical and Grease Resistance: TPO naturally resists damage from fats, oils, and chemical exhaust, making it an ideal choice for food processing plants and industrial manufacturing facilities.
• Puncture and Tear Strength: Reinforced with polyester scrim, modern TPO membranes handle foot traffic, heavy rooftop maintenance, and minor impact without splitting.

EPDM Roofing Systems

EPDM is a black, synthetic rubber membrane with a 40-year track record of proven performance in cold-climate regions.

• Extreme Temperature Flexibility: EPDM remains flexible even in sub-zero winter temperatures, accommodating intense building expansion and contraction without cracking.
• Hail & Impact Protection: The rubberized composition of EPDM absorbs heavy physical impacts, making it exceptionally resilient against Midwest hail storms.
• Proven Longevity: With proper seam maintenance and installation, high-grade EPDM systems regularly exceed 30 years of operational service life.
• Winter Thermal Gain: The dark surface of traditional EPDM absorbs solar heat during winter months, helping melt snow accumulation faster and reducing indoor heating demands.

Single-Ply Insulation & Deck Integration

A single-ply membrane is only as strong as the substrate beneath it. As experts in both commercial roofing and insulation, NIJAC ensures your complete roof assembly is engineered for maximum energy performance.

We integrate rigid Polyiso (Polyisocyanurate) insulation boards and high-density cover boards directly below the TPO or EPDM membrane. This eliminates thermal bridging, prevents condensation build-up inside the ceiling cavity, and creates a flat, puncture-resistant base for your single-ply system.

Single-Ply Roof Services

Whether you are retrofitting an existing building or planning new commercial construction, NIJAC provides full-lifecycle single-ply services:

• New Single-Ply Installation & Re-Roofing: Complete tear-offs or overlay systems using mechanically attached, fully adhered, or ballasted specifications.
• Seam Inspections & Repairs: Restoring compromised lap joints, wall flashings, and rooftop penetration boots before water reaches your insulation.
• Preventative Maintenance: Scheduled visual inspections and drain clearings to extend your system’s service life.
