Types of Commercial Roofing Systems We Install

We work with a variety of commercial roofing systems to meet different building needs and budgets. Each type offers distinct benefits depending on factors like durability, cost, and maintenance.

Flat Roofing Solutions

Flat roofing systems represent the cornerstone of commercial construction due to their exceptional installation efficiency, cost-effectiveness, and functional versatility. Our flat roofing expertise encompasses advanced materials including built-up roofing (BUR) systems, modified bitumen membranes, and spray polyurethane foam applications, each selected for their specific performance characteristics and environmental suitability.


These systems provide unparalleled accessibility for routine maintenance, HVAC equipment installation, and future building modifications. We implement sophisticated drainage design and premium sealing techniques to eliminate water infiltration risks, which represent the most critical vulnerability in flat roofing applications when installation standards are compromised.



Proactive maintenance programs are essential for flat roofing systems due to their inherent susceptibility to water accumulation and thermal cycling stress. We also integrate high-performance reflective coating systems that dramatically enhance energy efficiency by reducing solar heat gain, resulting in measurable reductions in cooling costs and improved interior comfort levels.

Metal Roofing Options

Commercial metal roofing systems deliver unmatched structural integrity and longevity for demanding commercial applications. These systems demonstrate superior resistance to fire hazards, severe weather events, impact damage, and environmental degradation compared to conventional roofing materials.


Our metal roofing installations utilize premium materials including galvanized steel, marine-grade aluminum, and architectural copper systems. Steel roofing remains the preferred choice for most commercial applications due to its optimal balance of affordability, structural strength, and extended service life. Aluminum systems offer exceptional corrosion resistance and reduced structural loading, making them ideal for coastal environments and weight-sensitive applications.



We install both standing seam and structural metal panel systems, with standing seam configurations providing superior aesthetic appeal and enhanced weatherproofing through concealed fastening systems. Metal roofing systems require minimal maintenance investment while consistently delivering 40 to 70 years of dependable performance when properly installed and maintained.

Single-Ply Membrane Systems

Single-ply membrane systems represent cutting-edge roofing technology, utilizing advanced synthetic sheets manufactured from high-performance materials including TPO (Thermoplastic Polyolefin), EPDM (Ethylene Propylene Diene Monomer), and PVC (Polyvinyl Chloride). These systems have become the preferred solution for flat and low-slope commercial applications due to their exceptional performance characteristics.


We favor single-ply systems for their lightweight construction, streamlined installation process, and superior resistance to UV radiation, chemical exposure, and thermal cycling. TPO membranes have gained widespread adoption due to their outstanding cost-effectiveness, heat-reflective properties, and proven long-term reliability in diverse climate conditions.



EPDM systems utilize advanced rubber membrane technology renowned for exceptional durability and flexibility across extreme temperature ranges. PVC membranes provide enhanced fire resistance and chemical compatibility, making them ideal for industrial applications with potential chemical exposure. These versatile systems accommodate multiple installation methods including fully adhered, mechanically attached, or ballasted configurations, allowing us to optimize installation approach based on specific building requirements and structural considerations.

Materials We Use for Commercial Roof Installations

We choose roofing materials based on durability, cost, and building type. Each option has unique features that suit different needs. Understanding these materials helps us recommend the right fit for your commercial roof.

EPDM and TPO Roofing

EPDM (Ethylene Propylene Diene Monomer) is a rubber roofing material known for its flexibility and resistance to weather. It performs well in both hot and cold climates, making it a popular choice for flat or low-slope roofs. EPDM is also easy to install and repair, which helps reduce labor costs.


TPO (Thermoplastic Olefin) roofing is a single-ply membrane made from a blend of rubber and plastic. It reflects sunlight effectively, which lowers cooling costs in warmer climates. TPO is strong against punctures and UV rays, and it welds at seams to create a watertight seal.


Both EPDM and TPO are lightweight and offer good energy efficiency. We select them when the roof design requires strong, flexible materials with long service lives.

Modified Bitumen

Modified Bitumen is a type of asphalt roofing that combines asphalt with polymers to improve flexibility and strength. It usually comes in rolls and is applied in layers on flat roofs. This material handles temperature changes well and resists cracking.


We often use Modified Bitumen with a torch-down method or cold adhesive, depending on site conditions. Its thick layers provide added protection against water and mechanical damage. Maintenance is straightforward, and repairs can be spot-focused, limiting overall costs.


This material is suitable for roofs needing a tough surface resistant to foot traffic and harsh weather.

Built-Up Roofing

Built-Up Roofing (BUR) consists of multiple layers of bitumen and reinforcing fabrics. It’s installed by hot-mopping layers together to form a thick, durable surface. BUR is known for its strength and waterproof qualities.


We recommend BUR for commercial buildings where heavy weather protection is needed. The many layers reduce the risk of leaks and improve insulation. It also handles foot traffic better than some single-ply options.


Because BUR is heavier and requires skilled installation, it tends to be more expensive upfront but offers a long service life if well maintained.

Compliance and Industry Standards

At Norwalk Superior Roofing, we follow all local building codes and regulations during commercial roof installation. This ensures safety and long-lasting results for every project.


We use materials that meet industry standards, such as those certified by ASTM International and Underwriters Laboratories (UL). These certifications show our products are tested and reliable.


Our team is trained to meet OSHA safety rules. This keeps our workers safe and avoids problems on the job site. We also work closely with city inspectors to get the necessary permits before starting any work. Inspections help confirm that our installations meet quality and safety standards.


Here is a list of key standards we comply with:


  • Building codes from local and state authorities
  • ASTM and UL material certifications
  • OSHA safety regulations
  • Manufacturer installation guidelines


Following these rules helps us deliver roofing systems that protect your business and meet legal requirements.
