While flat roofs are common in commercial buildings, they present unique challenges during installation. Installing a new roof is an expensive and time-consuming project, so it’s worthwhile to do your research and find a contractor you can trust.

Ribbon Roofing has been installing commercial flat roofing in Pittsburgh for years, and we understand the impact our local climate has on the structure of flat roofs. We have the experience and expertise to manage your flat roof, from installation to maintenance and beyond.

Different Types of Flat Roofing


Aluminum roofs are some of the most common commercial flat roofing found in Pittsburgh. The main advantage of metal roofs is their durability and ability to resist heat and weather damage.

A common misconception is that metal roofs heat up faster and are less energy-efficient than other roof materials. The truth is that metal roofs will reflect heat better than most other roof types, making them extremely energy-efficient.


Ethylene propylene diene monomer, or EPDM, is a synthetic rubber blend that’s easy to install but prone to leaks. Most roofers will choose EPDM for large open roofs, such as office buildings, due to its cost-effectiveness and durability. We strongly recommend applying a protective sealant that will stop leaks and prevent water damage.

Built-up Flat Roofs

Built-up flat roofs, or BURs, are made from alternating layers of tar and gravel. These roofs are incredibly durable, energy-efficient, and aesthetically pleasing, but they require experience to install correctly. The resulting roof is also very heavy, which places a lot of stress on the underlying structure.

Modified Bitumen

Modified bitumen is a combination of asphalt and modifiers and is considered ideal for commercial flat roofing. It requires specialized installation, but it’s durable, robust, energy-efficient, and affordable.



What are flat roofs used for in Pittsburgh?

Flat roofs are commonly found in commercial buildings, though some homes will have a flat roof over an extension or addition.

What are the advantages and disadvantages of commercial flat roofing?

Two significant advantages of flat roofs are that they provide easy access to components, such as vents and gutters, and are exceptionally wind- and storm-resistant.

The main disadvantage of a flat roof is that water tends to pool after a storm, causing water damage. Proper flat roof installation is vital to ensure adequate drainage.

How much does flat roofing cost?

Flat roofing is more affordable than sloped roofing. The final price depends on the materials used and the size of the project. Get in touch with our team at Ribbon Roofing for a free no-obligation quote. 

How long will commercial flat roofing last?

Your roof’s lifespan depends greatly on the materials used. Metal roofs can last up to 30 years, while EPDM roofs typically have a 15- to 20-year lifespan. 

How do you maintain a flat roof?

Flat roofs require just as much maintenance as sloped roofs. We recommend annual inspections in addition to inspections after large storms to identify potential damage or issues.

Al Colussi
I ended up spending about 2 hours talking with Al from Ribbon Roofing, everything with him was no non-sense and he was very knowledgeable about roofing and explained everything in simple to understand terms as well as giving me a price that I thought was fair for the both of us.
