While there are plenty of roofing materials available for commercial spaces, selecting the right roofing membrane from so many options can be an overwhelming experience for property owners. Even though TPO, EPDM, and PVC are the top choices among all flat roofing materials, you ultimately need to decide based on the roof’s design, the product’s essential properties, and curb appeal. To help, here is a comparative blog post of all three roofing membranes that will help you understand their individual properties and let you know which one to choose for your roof.
What Is A TPO Roofing Membrane?
A TPO roofing membrane is a popular single-ply roofing material known for its affordability and energy efficiency. TPO is widely chosen for its durability and UV resistance, making it ideal for flat or low-slope roofs.
1. Appearance
TPO roofing membranes usually come in white, which helps reflect sunlight and keep buildings cooler. If you are looking for something different, it also comes available in other colors like light gray, tan, terracotta, and patina green according to the appearance you’re trying to create for your commercial property.
2. Installation
Installing TPO is relatively straightforward and typically faster than other roofing options. It can be applied using heat welding techniques, making it watertight and durable against leaks. Regardless of how quickly it can be installed, it still requires a lot of professional help, and it can not be done using DIY techniques.
3. Cost
TPO roofing membranes are budget-friendly at around $4 to $14 per square foot, which makes it a top choice for those looking to save on upfront costs. Generally, it falls in the mid-range of roofing membrane costs, often less expensive than PVC but comparable to EPDM.
4. Durability
Commonly used in areas with high temperatures and humid climates, TPO is known for having resistance to UV rays and high heat-absorbing qualities. It is also resistant to punctures and can survive up to 20 to 30 years with proper maintenance and care.
5. Maintenance
TPO roofing membranes only require minimal care to keep them going for a longer period of time. Occasional cleaning and regular inspections are recommended to check for potential wear and tear, especially around seams and edges.
6. Energy Efficiency
TPO’s reflective surface is ideal for reducing energy consumption. It reflects sunlight, keeping buildings cooler in the summer, which can help lower air conditioning costs.
What is an EPDM Roofing Membrane?
EPDM is a synthetic rubber roofing membrane used in commercial spaces and flat roofs for its long-lasting and durable roofing system. Known for its flexibility and versatile properties that allow it to withstand various weather conditions, it is a popular choice for roofs among countless building owners.
1. Appearance
Typically a favorite choice for heat absorption in cooler climates, EPDM roofing membranes typically come in black. But if you are looking for something different and want to create a unique curb appeal for your building, you can find it in different colors such as white, beige, red, yellow, and eggshell to name a few.
2. Installation
To install an EPDM roofing membrane, a professional uses adhesives, fasteners, or a ballasted system with stones to keep it going for a longer period of time. EPDM has a long track record for reliable performance when professionally installed.
3. Cost
EPDM is generally the most affordable of the three membranes, coming in at around $5 to $8 per square foot, often appealing to budget-conscious homeowners. Due to its low cost and easy installation process, this roofing membrane is a cost-effective choice for many business owners.
4. Durability
EPDM roofs can last 25 to 30 years or more with proper care. The rubber material is highly resistant to extreme temperatures, hail, and UV rays, which adds to its longevity.
5. Maintenance
EPDM requires very little maintenance, but regular checks for damage and occasional cleaning can help extend its life. The flexible material also makes repairs easier if issues arise.
6. Energy Efficiency
While black EPDM absorbs heat, which can be beneficial in colder climates, white EPDM options offer improved reflectivity for those seeking energy efficiency in warmer areas.
What is a PVC Roofing Membrane?
A PVC roofing membrane is a durable, versatile option commonly used in commercial buildings. Its chemical resistance and strength make it highly reliable against various environmental factors.
1. Appearance
PVC roofing membranes are available in many different colors. Ranging from, white, black, orange, red, green, or yellow, a building owner can choose the right color of their roof according to their taste, need, and curb appeal of their commercial properties.
2. Installation
PVC roof installation usually involves heat welding to create a strong, leak-resistant seal. Installing a PVC membrane requires skill, precision, and years of experience, so make sure to hire a professional to ensure a quality outcome from your investment.
3. Cost
PVC is generally the most expensive out of the three options, coming in at around $6 to $18 per square foot. Because of its higher durability, energy efficiency, and chemical resistance, it comes at a higher price but still makes a profitable investment for property owners.
4. Durability
PVC is known for its enhanced durability, often lasting up to 20 to 30 years. It resists chemicals, fire, and high winds, making it a reliable choice in areas with extreme weather or rooftop exposure to chemicals.
5. Maintenance
PVC roofs are relatively low maintenance. However, regular inspections and cleaning can keep the membrane in good condition for a longer time and repairs are generally easy due to the material’s flexibility.
6. Energy Efficiency
With reflective properties, PVC roofing membranes are ideal for energy savings. White PVC, in particular, is highly reflective, reducing the need to use cooling systems frequently in hot climates, therefore lowering utility bills.
