TPO, EPDM and PVC Roofing Systems – What Are the Differences
Let’s compare these three roofing options to understand their pros and cons.
TPO and EPDM Roof
TPO single-ply membrane is an energy efficient and cost-effective roofing product. Its white reflective surface deflects sunlight and reduces cooling costs. So, it’s a popular choice for warmer climates or energy-conscious property owners. TPO system is also recyclable. However, its performance also depends on the manufacturer and roofing contractor, and it may not be as durable as EPDM in extreme weather conditions.
EPDM membrane, often called “rubber roofing,” is a highly durable material that works excellently in extreme weather. Synthetic rubber black surface absorbs heat, which can be a drawback in warmer climates but beneficial in colder regions. EPDM rubber is also easy to install and repair. However, it’s less energy-efficient than TPO and not as environmentally friendly due to limited recycling options.
What’s better?
- Choose TPO if energy efficiency, cost, and eco-friendliness are your top priorities.
- Choose EPDM single-ply membrane if durability and performance in extreme weather are more important.

EPDM vs PVC Roof
EPDM is a favorite material of many roofing companies. It performs exceptionally well in cold climates and is less prone to ultraviolet damage. However, its black surface can absorb heat, and it lacks the chemical resistance and seam strength of PVC.
PVC roofing membrane offers chemical resistance, fire resistance, and seam strength. It is often the best choice for commercial and industrial applications. PVC is also highly reflective, contributing to energy savings. However, its higher cost and complex installation can be a drawback for smaller projects or owners with restricted budgets.
What’s better?
- Choose EPDM if you need a durable, cost-effective solution for residential or cold-weather applications.
- Choose PVC if you require a high-performance membrane for commercial or industrial use, especially in harsh environments.
TPO vs PVC Roof
TPO is more affordable than PVC, but it offers similar benefits – energy efficiency and chemical resistance. It’s a great choice for commercial properties or residential buildings where the roofing budget has limits. However, TPO’s quality can vary, and it is sometimes not as durable as PVC in harsh conditions.
PVC is the gold standard for flat roofing membranes. Its winning features are superior chemical resistance, seam strength, and longevity. It’s resistant to fire, chemicals, and punctures. Roofers recommend it for buildings exposed to harsh elements or industrial environments. However, PVC is more expensive, and is not always appropriate for smaller projects like garages or sheds.
What’s better?
- Choose TPO if you are looking for a cost-effective, energy-efficient solution.
- Choose PVC if you need exclusive performance and a long-lasting roof.

Tips on Different Flat Membrane Installation
Roof Installation Nuances You Cannot Ignore
A flat roof design does not seem complicated. However, small flaws can quickly turn into serious issues. The first rule is to thoroughly prepare the base surface. Uneven areas can lead to standing water and quicker wear of the membrane. Chicago’s unpredictable weather also influences the installation. Strong winds can slow down the process, and cold temperatures do not allow adhesive to dry properly.
Rain is another challenge – trapped moisture between layers can cause bubbles and peeling over time. Additionally, remember about building codes in Chicago – flat roofs must meet specific wind resistance and insulation standards. And the main thing – each roofing material has its unique installation nuances that should not be overlooked.
What Is the Right Roofing Membrane for Your Chicago Property
Homeowners often struggle to select the right membrane for a flat roof. Everyone wants high-quality roofing that is affordable at the same time. So, here are some helpful suggestions:
For Residential Properties
If you are a homeowner, consider a TPO membrane for your building. This material reflects up to 80% of solar heat and reduces cooling bills by 15-25% during hot Chicago summers. A TPO roof can last 20-25 years if there are installation mistakes.
If you look for a durable roof, go with an EPDM roof. It is often chosen for its ability to withstand sharp temperature drops. Also, EPDM does not require super complicated maintenance.
For Commercial Properties
Businesses can benefit from PVC roofing. PVC costs 15-20% more than TPO or EPDM but provides excellent resistance to weather and even chemicals. Professionally installed PVC can last for 30 years and more.
If your commercial roofing system budget is limited, look at EPDM. It is a reliable and cost-effective option. EPDM works well on larger buildings with low slopes.
For Small Structures
What’s best for garages, sheds, or workshops? You should choose materials based on how the space will be used:
- TPO is lightweight and easy to maintain, so it is ideal for storage spaces.
- EPDM is simple to install and great for quick projects.
- PVC is best for workshops where chemicals or solvents are used due to its high chemical resistance.
If you are still unsure what membrane to buy, consult with a professional roofer for the best solution.
Things to Know About Flat Roof Membrane Repairs
A flat roof performs well as long as you care for it. Here are common issues you may face with TPO, EPDM, and PVC roofing systems and how to solve these.
- TPO Repairs
TPO roofs are relatively simple to fix when you spot issues in time. You can easily repair small tears or punctures with the help of patches. These patches are heat-welded – this method creates a seamless bond that ideally blends with the existing membrane. Make sure to regularly check seams as they can loosen over time. TPO has a flexible design, so repairs are relatively simple. - EPDM Repairs
EPDM is one of the easiest flat roofing materials to repair. You can fix small leaks or punctures with adhesive-backed rubber patches or liquid rubber sealants. The rubber surface makes the patching process simple. EPDM is often popular among both DIYers and professionals for its straightforward repairs. - PVC Repairs
PVC roofs are very durable but require more precision during repairs. Punctures or tears often need heat-welded patches to restore a seal. It is best done by professionals. PVC seams repairs are more complicated, but the risk of damage is less when it comes to PVC.
TPO, EPDM and PVC Installation Cost Comparison
It’s natural that everyone wants the best quality for the lowest cost. However, it’s crucial to consider both the initial and long-term costs. TPO is the most affordable option. Choose it for smaller buildings or auxiliary structures. EPDM systems have an average price and a good balance of durability and cost. It is great for residential or small commercial properties. PVC is a bit more expensive but delivers superior performance. It is a smart choice for larger or industrial buildings.
Long-term costs are also vital. TPO roofs are low-maintenance but may need repairs more often. White-on-black EPDM is affordable to repair and is good for long-term use. PVC is expensive initially but requires less maintenance and fewer repairs. Always take into account all these factors to decide what’s best for you.
The Importance of Working with Roofing Experts
