#1 Thermoplastic Polyolefin (TPO)
Cost: $4 to $10 per square foot
Thermoplastic polyolefin (TPO) has quickly become a top choice for flat roof replacements due to its exceptional performance and cost-efficiency.
TPO roofing membranes are highly durable and resistant to UV rays, which helps extend the lifespan of your roof. Their heat-welded seams provide superior strength compared to traditional adhesive or taped seams.
TPO roofs are also energy-efficient, reflecting heat and reducing cooling costs, making them an eco-friendly option.
Installation is relatively easy, saving you time and labor costs. Plus, TPO is available in various thicknesses and widths, allowing you to tailor the material to your specific needs.
Mostly Used For: It is a type of cool roof suitable for buildings that need high reflectivity, such as school buildings, offices, and malls.
#2 Ethylene Propylene Diene Monomer (EPDM)
Cost: $3 to $8 per square foot
Ethylene propylene diene monomer (EPDM) is another good material for replacing a flat roof. It is a strong rubber roofing membrane that combines longevity with flexibility.
It is extremely durable, typically lasting 30-50 years. EPDM’s rubber composition makes it resistant to UV rays, weathering, and extreme temperatures, which means lower maintenance costs.
Installation is straightforward, whether you’re using adhesive, mechanical fasteners, or ballasting.
Plus, EPDM’s flexibility allows it to conform to your roof’s shape, making it ideal for complex designs. It’s also an eco-friendly choice, as it can be recycled at the end of its life cycle.
If you want a cost-effective, long-lasting flat roof solution, EPDM could be the perfect fit.
Mostly Used For: EPDM is a popular roof material choice for garage buildings, carports, and medical buildings.
#3 Polyvinyl Chloride (PVC)
Cost: $3 to $5 per square foot
Polyvinyl chloride (PVC) stands out as a top choice for flat roof replacements. It withstands harsh weather conditions, including strong winds and heavy rain, really well. PVC is also resistant to fire, chemicals, and punctures, giving you peace of mind and reducing maintenance costs.
PVC is an energy-efficient material choice for flat roofs. It has a reflective surface that helps reduce heat absorption. This keeps your building cooler during hot months and lowers energy bills.
These roofs can function well for 20 to 30 years. PVC is also easy and simple to install, and the material is lightweight, which minimizes structural stress on your property.
Mostly Used On: PVC is a popular choice for bakeries, commercial kitchens, and restaurants.
#4 Built-Up Roofing System
Cost: $4 to $10 per square foot
Built-up roofing, often called BUR, is a common choice when replacing a flat roof. This type of roofing material uses multiple layers of fabric and bitumen. A built-up roof might be a good option if you’re looking to replace a flat roof.
One of the main advantages of a built-up roof is its toughness. It can stand up to fire, strong winds, and extreme temperatures. These roofs are also hard to tear or puncture, making them very durable. With proper care, a built-up roofing system can last 30 years or more.
When installing a built-up roof, you have choices for the top layer, like gravel or fabric sheets. These options allow you to customize the look of your roof. However, it’s important to know that installing a built-up roof takes time because of all the layers involved.
To keep a built-up roof in good shape, you’ll need to recoat it every so often. This helps it stay waterproof and look nice. One downside to consider is that built-up roofing systems use materials that aren’t eco-friendly.
Mostly Used For Built-up roofing systems are a popular choice for industrial buildings because they can withstand a lot of pressure and foot traffic.
#5 Modified Bitumen
Cost: $4 to $8 per square foot
Modified bitumen is a popular choice when replacing a flat roof. It’s made by mixing asphalt with materials like polyester or fiberglass, creating a tough and long-lasting roof.
When you replace a flat roof with modified bitumen, you get a roof that can handle both hot and cold weather without the risk of cracking or breaking. It’s also fire-resistant, which is important for many commercial buildings.
With proper care, a modified bitumen roof can protect your building for 20 years or more. They come in different colors and styles, so you can choose one that looks good on your building.
While modified bitumen roofs have many benefits, there are a few things to keep in mind. They’re heavier than some other roofing materials, so your building might need extra support. Also, if not installed correctly, water can pool on the roof, which can cause problems.
On the other hand, modified bitumen roofs are eco-friendly. When it’s time for a new roof, you can recycle it, which is good for the environment.
Most Used For: This flat roof material is a tough choice and is popular for industrial buildings, such as manufacturing factories.

Metal roofs are a common choice for flat roof replacements, offering durability and longevity. They can last for up to 50 years or more, depending on the quality of the material you choose.
There are many metal roof material options, with each having its own features, that you can choose for your building, like aluminum, which is lightweight and has a good strength-to-weight ratio. If you are looking for a rust and stain-resistant option, stainless steel is the best choice.
Metal roofs can withstand harsh weather conditions, which makes them suitable for both commercial and residential buildings.
When replacing a flat roof, metal roofing systems are known for their ability to reflect heat, which can significantly reduce energy costs—up to 30% in some cases. This energy efficiency is particularly beneficial in warmer climates, where cooling costs can be high.
They are also non-combustible, adding an extra layer of safety for your building. However, it’s important to understand that metal roofs can be heavier than some other roofing materials and may require additional structural support.
Most Used For: Metal roofs offer a modern look and they can be seen on many buildings including warehouses, schools, factories, and even homes.
