How Long Does a Commercial Roof Last?

Commercial roofs are a significant investment for any business, and understanding their longevity can help in planning for repairs or replacements. The durability of a commercial roof largely depends on a variety of factors, including the type of commercial roofing materials, installation quality, weather conditions, and maintenance frequency. In this blog, we will dissect these factors and provide insights into extending the lifespan of your commercial roof.

Factors Affecting the Lifespan of a Commercial Roof

Type of Commercial Roofing Materials

There are several types of commercial roofing materials, each with their own benefits and lifespans:

• EPDM Roofing: Known for its durability, EPDM roofing is a popular choice for commercial buildings and can last between 20-30 years with proper maintenance.
• PVC Roofing: PVC or polyvinyl chloride roofing is resistant to environmental impacts, making it a long-lasting option with a lifespan of about 20-30 years.
• Modified Bitumen Roofing: This roofing material is praised for its flexibility and strength, offering a lifespan of 20-25 years.
• Built-Up Roofing (BUR): BUR systems consist of alternating layers of bitumen and reinforcing fabrics, creating a finished membrane that can last between 15-30 years.
• Thermoplastic Polyolefin (TPO): TPO roofing is a cost-effective choice with a lifespan of 15-25 years.
• Asphalt Shingles for Commercial Buildings: While typically used in residential roofing, asphalt shingles can also be used in commercial settings and have a lifespan of 15-20 years.

Roof Installation Quality

The longevity of a commercial roof also heavily depends on the installation process. It’s crucial to select experienced commercial roofing contractors who can ensure the roof is properly installed. A poorly installed roof can lead to numerous problems down the line and significantly decrease its lifespan.

Climate and Weather Conditions

The impact of weather on flat roofs and slope roofs can be significant, as they are exposed to the elements 24/7. Factors such as UV exposure and temperature fluctuations can cause wear and tear over time, possibly leading to a shorter lifespan for the roof.

Maintenance and Inspection Frequency

Regular maintenance and inspections can greatly increase the lifespan of a commercial roof. A recommended roof inspection schedule includes bi-annual inspections and following any severe weather events. Regular maintenance can help identify and address common roof repair needs before they become costly problems.

Roof Design and Structure

The design and structure of your roof, particularly whether it’s a slope roof or a flat roof, can also impact its lifespan. A good design will include a proper drainage system to prevent water accumulation and damage.

Typical Lifespan of Different Commercial Roofing Systems

Different roofing systems have different lifespans, largely depending on the factors mentioned above. Provided with regular maintenance and ideal conditions, here are typical lifespans for various commercial roofing systems:

• EPDM Roofing: 20-30 Years
• PVC Roofing: 20-30 Years
• Modified Bitumen Roofing: 20-25 Years
• Built-Up Roofing (BUR): 15-30 Years
• Thermoplastic Polyolefin (TPO): 15-25 Years
• Asphalt Shingles for Commercial Buildings: 15-20 Years

Signs It’s Time for a Roof Replacement

While understanding the typical lifespan of commercial roofs is important, it’s equally vital to recognize signs that indicate it’s time for a roof replacement. These signs include visible damage and leaks, a noticeable decline in energy efficiency, frequent and costly roof repairs, or an expired manufacturer warranty.

How to Extend the Lifespan of a Commercial Roof

To maximize the lifespan of your commercial roof, consider implementing regular roof maintenance plans, working with certified commercial roofing contractors, installing energy-efficient roofing membranes, and scheduling roof inspections after severe weather.

Choosing the right roofing contractor is essential for long-term results. Look for contractors with certifications and industry credentials, experience in roofing projects for commercial buildings, and positive customer reviews and testimonials.
