It’s common for building owners and facility managers to not think about their roofs unless they have a reason. In most cases, it ends up being a major leak or failure in the system. When these types of issues show up on a commercial roof, it raises a lot of questions — from the cost of repair to the benefits of regular roofing maintenance.

Here are some of the common questions people ask about commercial roofing.

How do I know if my business needs a new roof?

Commercial roofs are meant to last for 10-30 years, and building owners should know when their warranty expires so they can make plans to replace their roof ahead of time. If you don’t know anything about your warranty information, you should have a professional roofer inspect it and give you advice about any replacement or repair options.

How long do commercial roofs last?

Commercial roofs that use a single-ply membrane system can last 10-30 years, but the lifespan of your roof will depend on the specific system, the thickness of the membrane, and any other elements in its design. Here are the averages for some of the common commercial roofing systems:

  • Spray polyurethane foam: 30-50 years.
  • Single-ply membrane TPO: 15-20 years.
  • Single-ply membrane EPDM: 20-25 years.
  • Metal: 30-45 years.
  • Built-up roofing: 10-15 years.

A professional roofer will be able to come up with a solution that’s based on your specific needs.

How much does it cost to install a new flat roof?

Single-ply membrane roofs can have a number of designs (depending on the building’s specific requirements), so prices can range from just a couple of dollars per square foot to more than $20 per square foot. It will, of course, depend on the complexity of the roofing system.

There are a number of factors that can affect the price. Some of them include but may not be limited to:

  • The size of your roof.
  • The condition of your existing roof.
  • Roof accessibility.
  • The choice of insulation.
  • The choice of membrane being used.
  • The choice of installation.
  • The presence of any roof penetrations.
  • The type of warranty.

Be sure to speak to a professional roofer for more information.

How can I keep my commercial roof maintained?

Most commercial roofing systems require some type of preventative maintenance. Manufacturers will often have their own specific recommendations, but roofing contractors will usually have service departments that building owners can contact during emergencies or when roofing maintenance is needed.

A study conducted by Firestone Building Products showed a roofing system with an average lifespan of 20 years will last beyond its warranty period if a preventative maintenance program has been implemented, while roofing systems with the same lifespan that don’t undergo regular maintenance will only last an average of 13 years. You want to treat your commercial roofing system as an asset, which is why you should make sure you have it inspected at least twice a year.

What is the best type of material for commercial roofs?

Single-ply commercial roofing membranes have properties that allow them to perform well in a number of different buildings. Roofers may also recommend EPDM, TPO, or PVC membrane (depending on the desired level of roofing performance). These membranes can have a number of different thicknesses, but thicker membranes tend to perform better.

What is TPO?

Thermoplastic polyolefin (TPO) is a type of single-ply roofing membrane that is made from flexible synthetic materials. It has a good performance rate because the materials are welded together, which makes it extremely durable. In fact, TPO membranes have a larger market share than any other roofing system in the U.S.

What is EPDM?

Ethylene Propylene Diene Monomer (EPDM) is the technical name for a rubber membrane commercial roofing system. EPDM roofs have been in use since the 1960’s, so they have proven track record. They can be installed in a number of different thicknesses and widths. They can be either mechanically attached, adhered, or ballasted.

What is the typical warranty for a commercial roof?

Warranties for commercial roofing systems can vary widely — from 12 months to 30 years or more. But it will depend on the type of roofing system being installed.

How long does it take to install a commercial roof?

The timeline for a commercial roof installation will depend on a number of factors, which can include the following:

  • The type of roof.
  • The size of your roof.
  • The presence of any existing damage.

Weather, inspections, and permits can also affect the timeline for completion. Every job is unique, so it can take anywhere from a few days to a few weeks. If you’re looking for one of the best roofing companies in Corpus Christi, be sure to reach out to Bayfront Roofing.
