Like everything else, your commercial roof has an expiration date.

While routine maintenance and repairs help ensure the longevity of your roof, eventually, a complete roof replacement will be the safest option for your building. As a property owner or manager, it’s important to understand the lifespan of commercial roofs and what factors affect a roof’s lifespan to make informed decisions about your next replacement. 

The following factors are known to influence the longevity of a commercial roof: 

Material selection

The type of roofing material you choose plays a significant role in determining how long your commercial roof will last. Each material has its own set of advantages and lifespan, so choosing the right one for your specific needs is crucial. The following is a list of the five most common commercial roofing materials, but be sure to consult with your commercial roofing expert when choosing which material is best for your property. 

Estimated material longevity: 

  • Metal Roofing – 40 to 70 years
  • Ethylene Propylene Diene Monomer (EPDM) – 20 to 50 years
  • Thermoplastic Polyolefin (TPO) – 10 to 30 years
  • Modified Bitumen – 20 years
  • Asphalt Shingle – 15 to 30 years

Climate and weather conditions

Roofs are our first line of defense, protecting properties from weather elements like rain, snow, hail, and UV rays. Your local climate and weather conditions can impact the lifespan of your roof, so it is important to consider weather patterns and your location when choosing a roofing material. Once your new roof has been installed, regular inspections and prompt repairs can help mitigate the effects of adverse weather.

Installation quality

The skill and expertise of the roofing contractor during installation can significantly affect the longevity of a commercial roof. Proper installation ensures that the roof can withstand environmental stresses and reduces the likelihood of premature damage. Fortunately, the first point of our Grizzly 5-Point Promise is Reliable Craftsmanship, ensuring high-quality craftsmanship on every project we complete. 

Maintenance practices

Regular maintenance is key to extending the lifespan of a commercial roof. Routine inspections, cleaning of debris, and addressing minor issues promptly can prevent small problems from escalating into major, costly repairs. 

Building design and usage

The design and purpose of a commercial building can impact the lifespan of its roof. Ventilation, foot traffic, and HVAC equipment have the potential to cause wear and tear on the roof, so it’s important that proper design considerations are made during the initial build.
