Here, we have some questions commonly asked about commercial roofing and getting accurate and full information is important to make the best decision:

What are the different types of commercial roofs?

There are many commercial roofing types, and each differs from residential roofing. Most commercial buildings have flat roofs over a larger span, and more attention and care has to be given to ensure that it is impermeable. If you do not address any weak areas, the end results can become a leak, and if it is a small leak, it will take its time damaging the structure. Mildew and mold will begin, creating a health hazard, not to mention the cost of the repair or replacement, which isn’t cheap for commercial roofing.

The key factors that determine what type of commercial roofing a building needs will depend on the building itself first, then the property owner’s budget. Just like on a residential property, the roof of a commercial property has an integral role in the healthiness and sturdiness of the structure and the roof. Factors that commercial roofing contractors take into consideration in suggesting which type of roofing is needed by the surrounding environment, climate, and any peripheral variables such as animals and foliage. Over time, each of those has a definite impact on a roof’s integrity. The roofs on most commercial structures are flat or have a low slope. This makes the choices of roofing materials fewer than a residential property. To provide an understanding of what commercial roofing types there available today, we offer the following information:

EPDM Rubber Roofs

This advanced material is used in many applications of various industries, such as automobiles, hoses, O-rings, and tubing. This is because it creates an excellent sealant and impervious layerperfect for flat commercial roofing systems. This membrane is perfect in ensuring that water doesn’t seep into the structure, preventing substantial damage.

The method used for installing An EDM rubber roof will create the effect of it. One method used is laying the material across the roof, using gravel to hold it in place. There are alternative methods using commercial roofing equipment specific for installing this material and then using EPDM specific fasteners with various types of glue that seal the membrane. EPD commercial roofing can last many years when properly maintained and care is taken when working on the rooftop, such as installing or repairing the HVAC system.

PVC Roofs

An excellent flat commercial roofing material is PVC. Inattention to being affordable, it has proven to be durable and waterproof. The standard process for installing PVC commercial roofing is in sheets that are then fastened or glued to the roof’s surface. Some commercial roofing contractors will lay gravel over it for reassurance it stays in place.

After they have applied the roofing material, the contractor will install insulation under it, then fasten that with a protective board. This will stop any current leaks and prevent water from seeping into the structure. The benefits of PVC commercial roofing that makes it a worthwhile investment are: 

  • It offers durability
  • Provides waterproofing
  • It is fire resistance
  • Lowers energy consumption
  • Has a long lifespan
  • It is weather resistance

TPO Roofs

TPO is short Thermoplastic Polyolefin, a single-ply commercial roofing material that is applied in sheets. For a state-of-the-air commercial roofing membrane, TPO is the perfect choice because of the many advantages it offers:

  • Provides energy efficiency
  • Stronger than other commercial roofing materials
  • UV ray resistant
  • Reflective white color

TPO commercial roofing material has a long lifespan and strong resistance to UV rays and water damage. It can be applied in several different ways:

  • Ballasted
  • Fully adhered
  • Mechanically attached

Any experienced commercial roofing contractor will be able to provide you the pros and cons of using TPO on your roof. Like any roofing material, if it isn’t installed properly in commercial roofing, it will shorten its lifespan.

How long should a commercial roof last?

The life expectancy of commercial roofing can vary, but when it is installed professionally and maintained properly, it can last anywhere from 10 years to 40 years. Some of the factors that can affect that life expectancy of the most common commercial roofing materials are:

  1. The Installation – Any errors or flaws during the installation can shorten the lifespan of a roof. This is why a commercial roofing job should always be done by an experienced, qualified commercial roofing contractor.
  2. The Slope – Water will pool more on a flat roof if it can’t flow off easily. Care needs to be given when installing a flat roof to avoid low spots because they are the weakest spots and prone to have water pooling.
  3. The Ventilation – Just as a residential roof, commercial roofing needs adequate ventilation too. This prevents heat and moisture from building up and minimize mold growth and rot.
  4. The Maintenance – Because commercial roofing is flat or low sloping, performing routine inspections and performing maintenance will prevent small problems developing into bigger problems.
  5. The Weather – The weather can damage any roofing. Commercial roofing is no different. Hailstorms, high winds, and everyday exposure are not a friend to a roof.
