When it comes to choosing the right commercial roofing material for your commercial property, understanding the life cycle of each option is crucial. It helps you determine which material offers the best performance, maintenance needs, and costs for your specific situation. In this article, we’ll discuss the life expectancy and characteristics of several common commercial roofing materials, including TPO, EPDM, PVC, metal roofing, and built-up roofing. We’ll also talk about factors that can impact their lifespan and how to keep them in good condition for as long as possible.

1. TPO (Thermoplastic Polyolefin)

TPO is a popular commercial roofing material for commercial buildings because it’s durable, energy-efficient, and easy to install. It’s made from a blend of plastic and rubber, which makes it resistant to the sun’s rays and able to withstand high temperatures. TPO roofs usually last between 15 to 20 years, depending on factors like installation quality, maintenance, and local weather conditions.

Factors affecting TPO life expectancy:

• Sun exposure and extreme temperatures
• Proper installation and strong seams
• Regular inspections and maintenance

How to maintain a TPO commercial roofing system:

• Inspect the roof at least twice a year and after major storms
• Keep the roof clean by removing dirt, debris, and algae growth
• Fix any damaged seams or holes right away
• Make sure water drains properly to avoid standing water

2. EPDM (Ethylene Propylene Diene Monomer)

EPDM is a synthetic rubber roofing material that’s flexible, long-lasting, and affordable. EPDM roofing systems typically last between 20 to 25 years, with some well-maintained roofing systems lasting up to 30 years. This commercial roofing system can handle extreme temperatures, sun exposure, and other weather conditions.

Factors affecting EPDM life expectancy:

• Sun exposure and changing temperatures
• Correct installation and flashing details
• Regular inspections and maintenance

How to maintain an EPDM commercial roofing system:

• Inspect the roof at least twice a year and after major storms
• Keep the roof clean by removing dirt, debris, and algae growth
• Fix any damaged seams, holes, or flashing problems right away
• Make sure water drains properly to avoid standing water

3. PVC (Polyvinyl Chloride)

PVC roofing is a durable and versatile commercial roofing system that resists chemicals, fire, and sun damage. PVC roofs usually last between 20 to 30 years, depending on the thickness of the material and the quality of installation. This type of commercial roofing is great for buildings with rooftop equipment or facilities that handle chemicals, as it can handle exposure to grease, oils, and other substances.

Factors affecting PVC life expectancy:

• Thickness of the material and installation quality
• Exposure to chemicals and sun damage
• Regular inspections and maintenance

How to maintain a PVC commercial roofing system:

• Inspect the roof at least twice a year and after major storms
• Keep the roof clean by removing dirt, debris, and chemical residues
• Fix any damaged seams, holes, or flashing problems right away
• Make sure water drains properly to avoid standing water

4. Metal Roofing

Metal roofing is a popular choice for commercial buildings because it’s long-lasting, durable, and energy-efficient. Common materials used for metal roofs include steel, aluminum, copper, and zinc. Metal roofs can last between 40 to 70 years, depending on the type of metal commercial roofing system and how well it’s maintained.

Factors affecting metal roof life expectancy:

• Type of metal and installation quality
• Regular inspections and maintenance
• Local weather conditions and sun exposure

How to maintain a metal commercial roofing system:

• Inspect the roof at least twice a year and after major storms
• Keep the roof clean by removing dirt, debris, and any signs of corrosion
• Fix any damaged seams, holes, or flashing problems right away
• Make sure water drains properly to avoid standing water and rust

5. Built-up Roofing System (BUR)

Built-up roofing, also known as tar and gravel roofing, consists of multiple layers of waterproof materials, including asphalt, and a top layer of gravel or crushed stone. These types of commercial roofing systems are known for their durability, weather resistance, and affordability. BUR roof systems typically have a life expectancy of 20 to 30 years, depending on the number of layers and the quality of installation.

Factors affecting BUR life expectancy:

• Number of layers and installation quality
• Regular inspections and maintenance
• Local weather conditions and sun exposure

How to maintain a built-up roofing system:

• Inspect the roof at least twice a year and after major storms
• Keep the roof clean by removing dirt, debris, and loose gravel
• Fix any damaged areas or signs of water intrusion right away
• Make sure water drains properly to avoid standing water and potential leaks

When should you choose one roof material over another?

In some situations, certain types of commercial roofing materials may be more suitable than others. Here are some examples of when you might prefer one type of commercial roofing materials over another:

1. TPO (Thermoplastic Polyolefin) Ideal for:

   • Buildings that require energy efficiency
   • Commercial roofing projects with budget constraints
   • Regions with high-temperature fluctuations

2. EPDM (Ethylene Propylene Diene Monomer) Ideal for:

   • Large, flat roofs that require a cost-effective solution
   • Buildings in areas with extreme temperature changes
   • Facilities where puncture resistance is less of a concern

3. PVC (Polyvinyl Chloride) Ideal for:

   • Buildings exposed to chemicals or harsh environments
   • Restaurants or facilities with grease or oil exposure
   • Projects that prioritize long-term durability and chemical resistance

4. Metal Roofing Systems Ideal for:

   • Buildings in areas with high wind or severe weather conditions
   • Facilities with a focus on energy efficiency and long-term durability
   • Property owners willing to invest in a higher upfront cost for a longer-lasting roof

5. Built-up Roofing (BUR) Ideal for:

   • Buildings that require a durable, weather-resistant roofing solution
   • Projects with moderate budgets
   • Facilities with easy access for heavy equipment needed for installation

When selecting the right commercial roofing systems for your commercial property, consider the specific needs of your building, the local climate, and your budget. Consulting with a professional commercial roofing contractor will help you make an informed decision that best suits your building owners’ situation.

Conclusion

Understanding the life cycle of different types of commercial roofing systems is essential for making an informed decision when selecting the right roofing solution for your property. Each material comes with its own unique set of characteristics, life expectancy, and maintenance requirements. By considering these factors and implementing proper maintenance practices, you can maximize the lifespan of your commercial roof and protect your investment. Always consult with a professional commercial roofing contractor to discuss the best option for your specific roof types and needs and to ensure a high-quality installation.
