A commercial roof should last anywhere from 20 to 40 years. Additionally, commercial roofs should last for a long time. That is, when correctly installed and maintained. The longevity of your roof will rely on a couple of different factors. Let’s look at the expected life spans of commercial roofing materials and what you can do to prolong it.
Different Commercial Roofing Material Lifespans
Different commercial roofing systems come with different life spans. Here are the main commercial roofing types:
Built-up Roofing (BUR)
Named because of its many layers, BUR roofing offers many benefits. Layers are usually applied upon a steel decking. Various layers include a water barrier, a roofing membrane, and a gravel surface layer. BUR roofing is cost-effective and offers multi-layer protection and energy efficiency. It’s also water, fire, and wind resistant. BUR roofs are designed to last between 20 and 30 years.
Modified Bitumen
Modified bitumen is a modern take on built-up roofing. Bitumen roofs differ from the recycled rubber used for EPDM roofing. They are composed of an asphalt composite. Bitumen roofs enjoy a lifespan of around 20 to 25 years when maintained correctly.
Thermoplastic Olefin (TPO)
TPO roofs can last for at least 20 to 25 years. Their blend of thermoplastics and elastomers creates a versatile choice for commercial roofing. TPO roofing is commonly used for shopping centers and warehousing roofs. TPO roofs require ongoing maintenance to extend their lifespan. Make sure you consult with them for all your roofing maintenance.
Ethylene Propylene Diene Monomer (EPDM)
EPDM roofing is incredibly durable. A recycled rubber construction gives it EPDM roofing a long lifespan. EPDM roofing enjoys a life expectancy of 20 to 25 years. This is key to its synthetic industrial-grade construction and application. It’s resistant to intense weather conditions and is ideal for large flat roofs.
Metal Commercial Roofing
Metal roofs can last anywhere between 30-45 years. Their adaptability makes them versatile options for flat or steep-sloping roofs. Routine maintenance is the key to prolonging the life of your metal roof. Most components are replaceable, which gives a metal roof an indefinite lifespan. This is all based on the quality of the metal and the continued workmanship that goes into your metal roof.
Factors That Affect Your Roof’s Life Expectancy
The following factors will shorten or prolong the lifespan of your commercial roof:
Quality of Installation
It’s important to ensure that you use a reputable roofing contractor. An experienced installer will know the ins and outs of your commercial roof. Getting the right contractor will help extend the life of your roof. Routine maintenance is also important to increase your roof’s longevity.
Slope
Flatter roofs are more likely to encounter water pooling. This water build-up can cause your roof to deteriorate and leak over time. The last thing you want is for a leak to damage your stock or office space. It’s important to get a consultant to inspect the flow pattern of your roof. Using higher-quality roofing materials will also counteract premature deterioration.
Ventilation
Roofs require adequate ventilation in their attic area. This helps to prevent heat and moisture build-up. This in turn will prevent rot and mold from developing. We know all too well how hot Florida summers can get. It’s best to ensure that you chat to your roofer about a ventilation plan for your roof.
Weather
Harsh weather conditions can directly damage your roof. Hurricane season in Florida is a time to watch out for roof damage. High wind speeds, heavy rain, and hail can all cause damage to your roof. Ongoing maintenance will ensure that your commercial roof stays intact during bad weather.
