Pros and Cons of Metal Commercial Roofing

Metal roofing has gained significant traction in the commercial building industry over the years. In this section, we will then delve into the advantages and disadvantages of metal roofing for commercial buildings.

Pros of Metal Commercial Roofing

Metal roofing offers numerous benefits for commercial buildings, making it a popular choice among property owners. Let's take a closer look at its pros:


Metal roofing is incredibly durable and can withstand harsh weather conditions such as heavy rain, strong winds, and extreme temperatures. It also has a longer lifespan compared to a traditional roofing material. When talking about fire resistance, metal roofing also comes out on top, making it a safe choice for commercial properties.

Low Maintenance

Metal roofing requires minimal maintenance, making it a cost-effective choice in the long run. Unlike traditional roofing materials that may require regular repairs and replacements, metal roofs can last for decades with little to no maintenance. This also means that you can save money on labor and repair costs.

Energy Efficiency

Metal roofs reflect sunlight instead of absorbing it like other roofing materials, reducing heat absorption and lowering cooling costs during warmer months. They are also great insulators during colder months, keeping the building warm and reducing heating costs. This makes metal roofing an energy-efficient option for commercial buildings.


Metal roofing is environmentally friendly as it can be recycled at the end of its lifespan. It is also energy-efficient, making it a sustainable choice for commercial buildings. Plus, metal roofs are often made with recycled materials, further reducing their environmental impact. This makes metal roofing a popular option for eco-conscious businesses.

Cons of Metal Commercial Roofing

While metal roofing has numerous benefits, there are also some downsides to consider. In this section, let's take a closer look into these cons.

Higher Initial Cost

Compared to other roofing materials, metal roofing typically has a higher upfront cost. However, it is important to keep in mind that its durability and low maintenance requirements can make up for this initial investment in the long run.

Noise Level

Rain or hail hitting a metal roof can be quite loud, especially compared to traditional roofing materials. This can be a concern for commercial buildings in busy areas or with noise-sensitive operations. With its noise reduction technology, however, this downside can be mitigated.

Expansion and Contraction

Metal roofing expands and contracts with temperature changes, which can lead to issues such as cracks or leaks if not properly installed or maintained. This is why it is crucial to hire a reputable and experienced contractor like this Denver roofing company for the installation of a metal roof.

Pros and Cons of Flat Commercial Roofing

Flat roofs are a staple when it comes to commercial buildings. Let's dive into the advantages and disadvantages of this roofing option.

Pros of Flat Commercial Roofing

Flat roofing has been a popular choice for commercial buildings for many years, and for good reason. Here are some of the advantages of choosing a flat roof for your commercial property:


Flat roofs are generally more cost-effective compared to other roofing options, making them a popular choice among business owners on a budget. With proper maintenance, flat roofing can last for decades. This means lower replacement and repair costs in the long run.

Extra Space

Unlike sloped roofs, flat roofs offer additional usable space that can be utilized for rooftop gardens, outdoor patios, or even solar panels. This added space is a valuable asset for commercial properties with limited land area. Plus, it can have a positive impact on the building's overall aesthetic.

Easy Maintenance

Flat roofs are easier and cheaper to maintain compared to other roofing options. Any repairs or maintenance work can be done quickly and efficiently, saving business owners time and money. This is especially beneficial for large commercial properties with extensive roofing areas.

Cons of Flat Commercial Roofing

Despite its popularity, flat roofing also has some drawbacks that should be taken into consideration before making a decision. Let's dig deeper into these drawbacks.

Limited Drainage

Flat roofs are prone to water pooling, which can cause leaks and other issues if not properly drained. This can be addressed with a well-designed drainage system, but it is an additional cost to consider.

Less Durable

Flat roofs are generally less durable compared to metal roofing and may require more frequent repairs or replacements. This can add to the long-term costs of maintaining a commercial property.

Lack of Aesthetic Appeal

While flat roofs have their own unique charm, they may not be as visually appealing as other roofing options. This can be a disadvantage for businesses that want to make a lasting impression on clients and customers with their building's exterior. Plus, flat roofs may not suit certain architectural styles, limiting design options.

Understand the Pros and Cons of Metal vs Flat Commercial Roofing

Both metal and flat commercial roofing have their own set of pros and cons. Metal roofing may come with a higher initial cost, its durability and low maintenance requirements can make it a more cost-effective choice in the long run. On the other hand, flat roofing may be a more budget-friendly option, but it may require more frequent repairs and maintenance.

Ultimately, the choice of roofing for commercial buildings should be based on careful consideration and research to ensure the protection and longevity of the property. Seek advice from a professional roofing contractor to determine the best option for your specific needs and budget.
