Commercial roofing is more technical than it may appear from the ground.
From drone inspections and 3D roof models to advanced roofing systems and smarter equipment, technology is changing how commercial roofs are inspected, maintained, repaired, and replaced. But technology is only one part of what it takes to deliver quality work.
Reliable Roofing President Mike Zimmermann recently joined host Mike Scott on AM 560 The Answer's Part of the Answer to discuss the changing commercial roofing industry, his unconventional path from attorney to roofing company owner, and the combination of expertise, technology, skilled people, and professional service that drives the business today.
Reliable Roofing is a commercial roofing company based in Lake Zurich, Illinois, serving commercial and industrial properties throughout the greater Chicago area.

From Law to Commercial Roofing
Before acquiring Reliable Roofing, Mike spent 23 years practicing law in Chicago, with extensive exposure to construction through regulatory and transactional work. That experience created a strong foundation for understanding the technical, contractual, and compliance-driven side of the industry.
Commercial roofing projects require much more than knowing how to install a membrane. Contractors must navigate manufacturer specifications, warranties, building requirements, documentation, inspections, and project details that can directly affect how the finished roofing system performs.
That broader perspective matters, especially on complex commercial and industrial properties where roofing decisions can have long-term operational and financial implications.
Commercial Roofing Is More Technical Than It Looks
Reliable Roofing primarily works with commercial and industrial properties, including industrial facilities, shopping centers, and commercial property portfolios.
Common commercial roofing systems include:
- TPO roofing
- EPDM roofing
- Modified bitumen
- Built-up roofing systems
Each system has its own materials, installation methods, manufacturer specifications, and performance requirements.
TPO, for example, is installed in large membrane sheets with seams that are heat-welded together to create the waterproofing layer. Those welds depend on proper equipment settings, temperature, speed, and trained operators.
What may look simple from the ground is actually a highly detailed system where installation quality matters at every step.
How Drones Are Changing Commercial Roof Inspections
Drone technology has become one of the most useful tools for modern commercial roof inspections.
Reliable Roofing combines traditional physical inspections with drone technology to capture high-resolution imagery and create detailed 3D views of commercial properties.
This can be especially valuable for property managers overseeing multiple buildings or managing properties from another city or state.
Instead of relying only on written reports or individual photographs, drone imagery can provide a more complete view of roof conditions and make it easier to understand what is happening across the property.
Drone-assisted inspections can support:
- Detailed roof-condition documentation
- High-resolution imagery
- 3D building and roof visualization
- Communication with property owners and managers
- Review of difficult-to-access areas
- Planning for repairs and future roofing projects
Reliable Roofing has multiple FAA-licensed drone pilots on its team.
The technology does not replace a physical roof inspection. It enhances documentation, visibility, and communication.
Smarter Equipment Is Making Roofing Safer and More Efficient
Technology is also changing how commercial roofing systems are installed and removed.
Robotic heat-welding equipment is increasingly used during TPO installation. While the equipment automates part of the process, it still requires an experienced operator to manage temperature, speed, and other variables that affect seam quality.
Roof tear-off equipment is advancing as well. Removing an existing commercial roof is physically demanding work, and smarter machinery can help reduce some of that burden while improving efficiency and worker safety.
The future of commercial roofing is likely to involve even more automation, but the goal is not to replace skilled workers. It is to give them better tools to perform demanding work more safely, accurately, and consistently.
Municipal Code Knowledge Adds Another Layer of Expertise
Commercial roofing projects are also affected by requirements that property owners may never see from the ground.
Reroofing requirements can vary by municipality, and local code amendments or energy-code requirements can influence how a commercial roofing project is evaluated and completed.
For example, whether an existing roofing system can remain in place or must be removed may depend on the existing roof assembly, local requirements, and the condition of the building.
That makes regulatory knowledge an important part of commercial roofing expertise.
Reliable Roofing's background in construction-related regulatory work provides added perspective when navigating municipal requirements, code considerations, manufacturer specifications, and compliance issues.
For commercial property owners and facility managers, that combination of roofing expertise and regulatory knowledge can be an important differentiator when planning a roof replacement or other major roofing project.
Commercial Roof Repair Can Extend the Life of an Existing Roof
A roofing problem does not automatically mean a building needs a complete roof replacement.
As the cost of owning and maintaining large commercial buildings continues to increase, repair and maintenance have become even more important.
When conditions allow, targeted commercial roof repairs and ongoing maintenance can help address specific problems and extend the useful life of an existing roofing system.
The right approach depends on factors such as:
- Overall roof condition
- Age of the roofing system
- Existing roof assemblies
- Membrane and seam condition
- Flashing and penetrations
- Drainage
- Insulation and moisture conditions
- Roof deck condition
- Manufacturer requirements
- Applicable municipal requirements
A thorough commercial roof inspection helps establish what is actually happening with the roof before decisions are made about repair or replacement.
Technology Still Requires Skilled Roofing Professionals
Better technology does not replace the need for skilled, experienced roofing professionals.
Commercial roofing systems must be installed according to detailed manufacturer specifications, and completed systems are often inspected before certain manufacturer warranties are issued. Crews need to understand the requirements of each system and execute the work correctly.
Maintaining that level of quality requires continuous training, hands-on experience, and a strong understanding of roofing materials, installation methods, and evolving technology.
That expertise also makes commercial roofing a strong career path for people who enjoy hands-on work and want to develop specialized skills. While construction may not receive the same attention as technology or traditional office careers, skilled professionals remain essential to building, maintaining, and protecting the properties businesses rely on every day.
Why Professionalism Matters in Commercial Roofing
Technology and technical expertise matter, but professionalism is just as important to commercial property owners.
Reliable Roofing approaches customer service much like hospitality: answer calls, respond to emails, explain issues clearly, follow through on commitments, and find answers when they are not immediately available.
Property owners and managers are often balancing tenants, employees, operations, budgets, and schedules while a roofing project is underway. Clear communication helps them understand what is happening, what decisions need to be made, and what to expect throughout the project.
Technology can improve the customer experience, but it can't replace responsiveness and accountability.
Building Relationships Before a Roof Needs Replacement
Reliable Roofing takes a relationship-driven approach to commercial roofing, focusing on long-term partnerships rather than one-time bids.
Those relationships often begin with an inspection, maintenance issue, or repair, giving the team time to understand the property, its roofing history, and its ongoing needs.
By the time a larger capital project or full roof replacement becomes necessary, the customer is already working with a roofing company familiar with the building.
This continuity supports more informed planning, better decision-making, and a less reactive approach to long-term roof management.
What's Next for Commercial Roofing?
Commercial roofing will continue to evolve as new technology changes how roofs are inspected, installed, maintained, and removed.
Drones and 3D modeling are already improving inspections, while robotic welding and more advanced tear-off equipment are helping crews work more efficiently and safely. Artificial intelligence and smarter machinery could accelerate those changes even further.
Even as technology advances, skilled professionals will remain essential. Commercial roofing still requires knowledge of roofing systems, manufacturer specifications, municipal requirements, safety standards, and proper installation practices.
Property owners will also continue to value contractors who communicate clearly, follow through, and provide dependable service.
The greatest value of technology will be in helping experienced roofing professionals work more safely, accurately, and efficiently.
For Reliable Roofing, the future of commercial roofing is about combining technology, skilled craftsmanship, regulatory knowledge, detailed inspections, and professional service to help businesses throughout the greater Chicago area protect and manage their roofing systems.
Frequently Asked Questions
How are drones used in commercial roof inspections?
Drones can capture high-resolution images and create detailed visual models of commercial roofs. They help roofing contractors document conditions and give property owners and managers a clearer view of what is happening on the roof. Reliable Roofing uses drone technology alongside physical roof inspections.
Why does municipal code knowledge matter for commercial roofing?
Commercial roofing requirements can vary by municipality. Building and energy-code requirements may affect how an existing roofing system is evaluated and what is required for a roof replacement or recovery project. Understanding those requirements helps contractors properly evaluate and plan the work.
Does a leaking commercial roof always need to be replaced?
No. Depending on the roof's condition and the extent of the problem, targeted repairs and maintenance may be appropriate. A commercial roof inspection can help determine whether repair, continued maintenance, or replacement is the best next step.
