What are Commercial Membrane Roofing Systems?
A commercial membrane roofing system is a type of flat or low-slope roof covering designed to provide a watertight barrier against weather, UV exposure, and mechanical wear. The most popular type is single-ply roofing, which includes membranes like TPO (Thermoplastic Polyolefin), EPDM (Ethylene Propylene Diene Monomer), and PVC (Polyvinyl Chloride).
These membranes are factory-manufactured in sheets and installed in large rolls. They are either mechanically fastened, fully adhered, or ballasted, depending on the building’s design and budget considerations.
There has been constant innovation in the single-ply membrane space, resulting in multiple options, each with its own benefits.
TPO (Thermoplastic Polyolefin)
TPO is one of the fastest-growing single-ply roofing materials in the commercial roofing industry. It’s popular for its bright white reflective surface, which reduces heat absorption and can lower cooling costs.
- Heat welded seams: Creates a monolithic, watertight bond that is stronger than taped or glued seams.
- Chemical Resistance: TPO resists mold growth, dirt accumulation, and chemical exposure, making it ideal for environments with light industrial activity.
- Thickness Options: Available in multiple thicknesses (typically 45, 60, and 80 mil), providing options based on performance needs and budget.
EPDM (Ethylene Propylene Diene Monomer)
EPDM is a synthetic rubber roofing membrane known for its outstanding weatherability. It has been used in commercial roofing for over 40 years and performs well in a variety of climates, particularly colder regions.
- Flexibility: EPDM retains flexibility in freezing temperatures, making it a smart choice for areas like Pennsylvania where winters can be harsh.
- Installation Options: It can be installed using ballasted, fully adhered, or mechanically attached methods.
- Color Choices: Available in black or white; black EPDM absorbs heat and can help reduce snow accumulation in colder months.
- Proven Track Record: EPDM roofs have a long history of performance and are often chosen for their reliability and ease of repair.
PVC (Polyvinyl Chloride)
PVC is a strong, durable membrane often used in environments where resistance to chemicals, grease, or oil is necessary, such as restaurants, airports, or manufacturing plants.
- High Puncture Resistance: The reinforcement layer in PVC membranes offers excellent durability, making it suitable for high-traffic roofs.
- Heat Welded Seams: Like TPO, PVC uses heat welding to form strong, watertight seams that resist leaks and storm damage.
- Fire and Chemical Resistance: It performs exceptionally well in conditions where exposure to contaminants or fire is a concern.
- Longevity: With proper maintenance, PVC roofs can last 20–30 years, offering a strong return on investment.
What Do Commercial Membrane Systems Include?
- Insulation Board: Improves energy efficiency by reducing heat transfer between the interior and exterior of the building.
- Membrane Layer: The primary waterproofing barrier. It is rolled out in large sheets and joined at the seams to prevent leaks.
- Fastening System: Depending on building design, membranes can be mechanically fastened, fully adhered, or ballasted with stone or pavers.
- Flashing and Edge Details: Essential components to waterproof penetrations like vents, pipes, and corners where water can enter.
- Drainage System: Commercial roofs must efficiently move water off the surface to prevent pooling. Scuppers, internal drains, or tapered insulation may be used.
