How Long Does a Commercial Roof Last?

How Long Does a Commercial Roof Last?

November 30, 2019

Commercial roofers in Toronto will tell you that many factors determine the duration of life your flat roof will enjoy. The Devil is always in the details, and for a commercial roof, it starts with materials. Once you have determined the materials are suitable, the workmanship to install the roof will be paramount to the life of a commercial flat roof. Roofing companies will tell you that many factors go into the timeline of a commercial flat roof. Care and regular maintenance will be necessary – if you are on top of the little things, you have nipped big problems in the bud. The type of roof you choose will come with a lifespan, and the cost is relative to the time the roof will last.

Common Factors that Affect the Lifespan of a Roof

  • Materials
    • Metal
    • EPDM – ethylene propylene diene monomer
    • TPO – thermoplastic polyolefin
    • PVC – polyvinyl chloride
    • Asphalt
    • Copper
  • Maintenance
    Commercial roofing maintenance can be conducted in two different ways. First, reactive maintenance is done when problems are identified, and work needs to be done. In general, it involves leaks, missing flashing, or ponding. Proactive maintenance starts with a plan that incorporates regular inspections, regular roof cleanings, and small repairs as discovered through examinations or cleanings.
  • Workmanship
    Workmanship is a professional stamp on the work you do. It requires superior attention to detail and execution of the task at hand. That creates the best practices in the roofing industry when installing the materials to create longevity. You can have the best roofing system in the world, but if roofing guidelines aren’t followed, it is a problem. When poor installation, incorrect installation, or sloppy installation practices have been used, the roof won’t be worth a thing.

Typical Lifespan of Different Roofing Types

A metal roofing system will hold a lifespan of 50-years or more when installation guidelines are followed.

The modified bitumen roofing system will provide coverage for 10-20-years, and it is an economical solution for strained maintenance and repair budgets.

EPDM (Ethylene Propylene Diene Monomer) Roofing is good for five decades. A membrane system will hold many advantages for a commercial structure that needs a high-quality roofing solution.

Spray Foam insulation will last a lifetime and then some. It is the ultimate answer to any roofing problem. Filling holes, cracks, and crevices while reinforcing your structure is what makes this system great.

TPO (Thermoplastic Polyolefin Roofing will provide a service life of 50-years. Another membrane solution that has applications all across the roofing spectrum, and you can’t go wrong with this system.
