Types of Commercial Flat Roofs

Let’s be honest. Picking a flat roof isn’t something most people think about until they have to. But when it’s time, you want it done right. You want a roof that holds up when rain pounds down or the summer heat beats on your building. For many business owners, flat roofs like TPO or EPDM end up being the pick. Some other types of commercial flat roofs include PVC, modified bitumen, and built-up roofs. They last, don’t require much maintenance, and save you trouble. However, not every building needs the same roof. That’s why you need to know about the different types. So, let’s understand each type to see what fits your place best.

Different Types of Flat Roofs for Commercial Buildings

Here’s what you need to know: 

1. Built-Up Roofing (BUR)

Built-up roofing is an old-school option you see on warehouses that have been around forever. BUR uses layers of tar and fabric, then tops it with gravel. That gravel isn’t just there to look rough; it keeps the sun from burning the roof and helps water drain.

People like BUR because it’s strong enough to walk on without worry. It can handle heavy rain and shrugs it off if installed well. But here’s the thing: it’s heavy. Not every building can take that weight without adding support. It also takes longer to put on, which isn’t ideal if you need a quick solution.

2. Modified Bitumen Roofing

Think of modified bitumen like BUR’s younger sibling with a flexible side. It’s asphalt mixed with rubber or plastic, which helps it bend when the weather swings from hot to cold.

It’s rolled onto your roof and heated, so it seals up tight. It holds up under foot traffic and keeps leaks away if you look after it. Typically, these roofs can last 20 or more years, which is suitable for many businesses needing a tough, flexible option.

3. EPDM Roofing

Rubber roofing might sound odd, but EPDM is just that. It comes in big rolls, black or white, and it’s glued down or held with fasteners.

Why do people like it? It’s light but tough and doesn’t crack easily in cold weather. If you get a rip, you can patch it without redoing the whole roof. With a bit of care, it can last up to 50 years, sometimes more. You know, it’s a “set it and check it” kind of roof.

4. TPO Roofing

TPO has become a popular choice for many flat roofs. It’s one layer made from rubber and plastic blended together. It’s usually light-colored, which helps keep the sunlight away instead of pulling in heat.

Your building stays cooler, and your AC doesn’t have to work hard. TPO also resists grime and algae, so it looks cleaner over time. Many owners go with TPO for its blend of price, durability, and the comfort of lower cooling bills.

5. PVC Roofing

PVC roofs are another single-ply option, but they’re a bit tougher with chemicals. Restaurants or factories like them because they don’t break down if oil or chemicals hit them.

They reflect sunlight to keep your building cooler and hold up well under foot traffic. If maintained properly, these roofs can last 25 years or more without giving you headaches.

6. Green Roofing

Green roofs, or living roofs, are made of plants and grass layered over a waterproof sheet on top of a building. They soak up rain, keep heat out, and add a bit of green to your space.

Sure, they cost more and need care, like watering and trimming. But they can lower heating and cooling bills and give you a peaceful spot even in a busy area. It’s worth a look if you want a roof that helps the planet while helping your building.

Conclusion

Choosing the right flat roof can seem daunting, but it’s worth taking your time. For many, TPO or EPDM is the easy pick because they last and don’t demand constant care. But BUR, modified bitumen, PVC, and green roofs each have their place, depending on your building’s needs.

Think about your plans, your building’s age, and what weather hits hardest in your area. If you need a hand sorting it all out, The Roof and Co. is ready to help you pick a commercial flat roof that protects your business without giving you more to worry about.
