Key Takeaways

• Commercial roofing systems differ greatly in energy efficiency, maintenance needs, cost, and durability. 
• Single-ply membranes like EPDM and TPO are the most widely used roofing options for commercial properties.
• The US Department of Energy has said that cool roofing systems can lower roof surface temperatures, helping enhance building energy efficiency. 
• The best commercial roof depends heavily on the long-term performance objectives, budget, local climate and the building’s structure

Arizona’s commercial buildings experience some of the harshest weather conditions in the United States. Occasional high winds, monsoon storms, prolonged summer heat, and intense UV exposure can place significant stress on commercial roofing systems. Commercial roofing does a lot more than protect a building from the elements. It also enhances energy efficiency and supports uninterrupted business operations. Picking the correct roofing system can lower maintenance costs and help it withstand Arizona’s demanding climate. This blog explains the various commercial roof types so that you can pick the one based on your needs and budget. 

Choosing the Right Commercial Roof: Why Does It Matter?

Opting for the correct roofing system can have an impact on the lifespan and performance of the building. A poorly suited roof might need periodic repairs, create functional disruptions, and increase power expenses. In contrast, a properly chosen roof can offer years of dependable protection. According to recent searches, cool roofs can stay over 50°F cooler than traditional roofing materials under sunlight. Lower roof temperatures can enhance building efficiency and lessen cooling demands. This makes roofing material selection an essential business decision. 

What Are the Various Types of Commercial Roofs?

You may come across many types of commercial flat roofs, and each of them has its own set of benefits. Here are some of the popular ones:

TPO Roofing

TPO (Thermoplastic Polyolefin) is the most well-known commercial roofing system these days. Opting for this roof type can lead to the following:

• Inexpensive installation.
• Energy-efficient reflective surface.
• Offers robust performance.
• Resistance to ultraviolet (UV) rays.

TPO is usually used on industrial facilities, retail centers, office buildings, and warehouses. This roofing system is ideal for Arizona's hot climate because it reflects intense solar heat, can withstand high temperatures, handles monsoon weather, and resists chemical exposure, mold, and dirt. 

Modified Bitumen 

Modified Bitumen roofing system is a multi-layer, durable roofing system that is created for low-slope commercial roofs. It provides outstanding resistance to foot traffic, weather damage, and puncture. Its flexibility can help it withstand Arizona's intense heat and seasonal temperature fluctuations, making it a low-maintenance and reliable option for long-term room protection.

EPDM Roofing

This is also known as rubber roofing, which is a highly durable single-ply membrane. Opting for this commercial roofing system can lead to these advantages:

• Relatively low maintenance needs.
• Provides flexibility in changing temperatures.
• Has a long service life.
• Offers outstanding weather resistance options.

EPDM performs extremely well in areas that experience temperature fluctuations. 

PVC Roofing

PVC (Polyvinyl Chloride) roofing is known for its chemical resistance and strength. Opting for this roofing system can provide commercial property owners with the following:

• Energy-efficient reflective properties.
• Higher durability.
• Offers a strong waterproofing performance.
• It is resistant to chemicals and grease. 

PVC roofs are installed frequently on commercial buildings, manufacturing facilities, and restaurants with rooftop equipment. 

Metal Roofing Systems

Metal roofing systems are the most durable commercial roofing option available. Many of these roofs can last for many decades when they are maintained properly. They are also highly resistant to severe climate, wind, and fire. Apart from that, these roofing systems stand out for these reasons:

• They are made of recyclable material.
• Energy efficiency.
• Low maintenance needs.
• Strong weather resistance.

Even though the initial investment might be a bit higher, long-term durability usually offsets the upfront expenses. 

BUR (Built-Up Roofing)

BUR has been used on commercial properties for countless years. This roofing system consists of many layers of reinforcing materials and asphalt that can create a durable barrier. It is also known for the following reasons:

• Provides long-term performance.
• Offers waterproofing options. 
• Good resistance to food traffic.

BUR roofing systems can be found in low-slope or flat commercial roofs.
