Roof restoration isn’t a job that anybody can do. Commercial roof repair companies operate in a specialized industry with its own terminology, knowledge, and tools. When dealing with business-grade roofing, these providers work on a larger scale and must achieve craftsmanship that withstands stiff weather conditions and meets the heavy demands of businesses.

It’s no surprise then that commercial roof repair companies use a wide variety of materials in their work. When deciding on the ideal option for your project, professionals gauge the strengths and drawbacks of each material in the context of your use case and preferences.

Let’s talk about some of the most common materials used in roof repair and in what cases each works best.


PVC stands for polyvinyl chloride. These roofs are multilayered and come with polyester reinforcements. Not only lightweight and easy to install, but PVC is durable against wind, water, heat, and even chemicals. Some commercial roof repair companies can even make them resistant to the sun’s UV rays. You’ll often see this material used for flat roofs.

However, PVC isn’t perfect. It’s known to shrink over time and strain the building’s structure in the process. It’s also expensive and not too durable against colder climates. PVC roofs also call for careful maintenance as they aren’t easy to repair.


Ethylene propylene diene monomer, or EPDM, is the primary ingredient of rubber-based roofs, which offer great value for the money thanks to low prices and ease of installation. They’re also lightweight and thus easy to repair and maintain and tend to last up to 2 decades.

The drawbacks of EPDM are that they’re vulnerable to sudden shock damage from hailstorms or falling branches. The thick, black rubber coating that covers the roof absorbs heat readily in the summer, raising air conditioning costs. Plus, many companies don’t like how they look.


Thermoplastic polyolefin, or TPO, is another low-cost solution for your roofing needs. Commercial roof repair companies love to advertise its ability to reflect heat and reduce internal cooling costs. TPO is also resistant to corrosion, algae, and mildew growth.

During TPO roof installation, the contractor fastens the leak-resistant seams to add additional protection against rain and seeping water.

One aspect of TPO worth mentioning is that it’s weak against fire damage, so your business will have to invest even more in fire retardants.
