Commercial Roofing Experts Since 1983

Your commercial roof has an undeniably important job. It protects your equipment, your product, your employees, your investments. It protects your business!

Because of its constant exposure to wind, rain, snow, hail and heat, it is a vulnerable part of your building. A properly installed, high quality commercial roof can withstand these harsh weather conditions and last longer than a roof that's made of cheap materials or that wasn't installed correctly.

Whether you need a new commercial roof or repair on an existing one, we can help.

Check out our Guide to Commercial Roofing to learn about the various commercial roofing materials, pros and cons of each, average installation and repairs cost, and more.

Commercial Roofing Installation and Repair

Commercial Roof Installation

Not all commercial roofs are the same. We specialize in high quality, single-ply commercial roofing systems, including:

  • PVC
  • EPDM
  • TPO


PVC (polyvinyl chloride) is a flexible thermoplastic membrane with excellent weathering properties. It is cost-effective, durable, fire-resistant, reflective, reliable, strong, lightweight, and long-lasting. Read more about PVC roofing systems.


EPDM (ethylene propylene diene monomer) is an extremely durable synthetic rubber roofing membrane most commonly used on low-slope commercial buildings. EPDM is available in either black or white, 7.5’ to 50’ wide, and 45, 60, 75 and 90 mils thick. Read more about EPDM roofing systems.


TPO (thermoplastic polyolefin) is the most affordable of the commercial roofing options. It is a reflective roofing membrane made from polyprophylene and ethylene-propylene rubber polymerized together. A TPO roofing system is often preferred on commercial buildings that use cooling equipment. The TPO membrane reflects UV radiation which helps keep the surface of the roof cool.

We are proud to install commercial roofs from the industry’s best brands:

Commercial Roofing Repair

Common commercial roofing problems that should be repaired include:

  • leaks
  • blow-off or billowing
  • flashing problems
  • ponding

Water leaks are the most common roofing problem. We will be able to discover small water leaks before they turn into a large and costly problem for your business.

Blow-off or billowing is when part of your roof becomes loose and completely comes off. Often, this is caused because the adhesive was not applied properly or there wasn’t enough it applied during installation. We can find these billowing problems and secure them once again.

Flashing is used to keep water from getting into certain seems on your commercial roof. By inspecting your  roof, we will be able to get the flashing replaced before it causes serious damage.

Ponding is when water collects on your roof and doesn’t drain properly. We can find these water ponds or puddles and get a proper water drainage system in place before they cause significant and costly damage.

With our commercial roofing maintenance and repair services, we can help you keep your roof in top condition, saving you money now and in the future. We’ve worked on a wide range of commercial roofs and can handle any challenge. Plus, our technicians are licensed, insured, and bonded to work on any project, big or small.
