Roof Systems 101 | Episode 1

What Is TPO Roofing?

TPO stands for Thermoplastic Polyolefin, a single-ply roofing membrane that has become one of the most widely used commercial roofing systems in the United States. It is known for its durability, energy efficiency, and heat-welded seams that help create a watertight roof system.

How is TPO installed?

TPO membranes are typically installed over insulation and can be:

• Mechanically attached
• Fully adhered
• Induction welded using systems such as RhinoBond®

The seams are heat welded together to form a strong, watertight bond.

Why do building owners choose TPO?

TPO roofing offers several advantages, including:

• Reflective white membranes that can help reduce heat absorption and cooling costs
• Excellent resistance to UV exposure and weathering
• Heat-welded seams for added durability
• Lightweight construction
• A cost-effective option for many commercial buildings

Where is TPO commonly used?

TPO is a popular choice for:

• Warehouses
• Distribution centers
• Office buildings
• Retail centers
• Manufacturing facilities
• Schools
• Healthcare facilities

It is also commonly specified for many new construction and reroofing projects.

How long does a TPO roof last?

A professionally installed and properly maintained TPO roof can often provide 20 to 30 years of service. Actual lifespan depends on factors such as installation quality, climate, rooftop traffic, drainage, and ongoing maintenance.

How can you help maximize its lifespan?

Routine inspections and preventive maintenance can help identify small issues before they become costly repairs. Keeping drains clear, removing debris, repairing punctures promptly, and documenting maintenance can also help support applicable manufacturer warranty requirements.

What should building owners watch for?

While TPO is a durable roofing system, it’s important to monitor for:

• Punctures from foot traffic or dropped tools
• Open or damaged seams
• Loose flashing around penetrations
• Ponding water caused by poor drainage
• Debris blocking roof drains
• Damage from unauthorized rooftop work

Addressing these issues early can help extend the life of your roof and reduce repair costs.

Is TPO the right roof for your building?

Every building has different needs. Factors such as building use, climate, rooftop equipment, budget, and long-term goals all play a role in selecting the right roofing system.

At O’Hara’s Son Roofing (OSR), safety is built on strong relationships, thoughtful planning, and a commitment to helping others succeed. Lydia Bryant, our Safety Coordinator, brings all of those qualities to her role every day.

With a background in human services, Lydia has spent the last three years helping build and strengthen OSR’s safety programs from the ground up. When she is not supporting our field teams, she enjoys spending time outdoors with her family, including her husband, Ben, and their two young children, Walter and Juliet.

Lydia’s approach to safety is simple: plan ahead, understand the hazards, and communicate with your team. Through training, engagement, and support, she helps ensure our crews have the knowledge and resources they need to work safely every day.

In one sentence, how would you describe your approach to safety?

Plan your work ahead, understand the hazards, and communicate with your team.

Safety doesn’t start when you arrive on the job site. It starts during the planning phase. Planning ahead means making sure you have the right tools, PPE, and a clear sequence of operations before any crew member lifts a finger.

You cannot avoid a hazard you don’t see. Understanding hazards is critical to the work we do at OSR. It requires continuous education, situational awareness, and a healthy respect for the environment you’re working in.

A safety plan only works if your team understands it. Open communication helps ensure everyone is on the same page, feels comfortable speaking up, and looks out for one another.

When it comes to critical safety decisions, what is one situation every worker should know how to handle correctly?

Fall prevention activities.

Falls remain one of the most common and serious risks we encounter during our work at OSR. Every worker should understand how and when to inspect their gear, how to properly use barriers and active tie-off points, and how to identify and eliminate fall hazards before work begins.

What does an effective and engaging safety training look like to you?

An effective and engaging safety training provides relevant, up-to-date information and allows participants to actively engage throughout the process. Team members should be encouraged to ask questions and connect the information to real-life situations before they encounter a hazardous scenario in the field.

In a high-pressure or unexpected situation, what is the first thing you focus on to keep everyone safe?

Stop. Assess. Act.

Stop and breathe. Secure the scene by removing immediate hazards and finding a partner to help.

Assess the situation. Check for injuries, call for help, and identify any unknown risks.

Take action by administering first aid or contacting emergency medical professionals.

Emergencies often happen without warning and can be incredibly difficult to manage. Remember that no one handles chaos perfectly the first time. Give yourself some grace if your initial reaction is not flawless.

At O’Hara’s Son Roofing (OSR), safety is not just a policy. It is part of who we are. We are proud to spotlight Hosea Moser, whose 11 years as a service technician reflect a strong commitment to safety, quality, and professionalism on every job.

In his role, Hosea responds to multiple service calls each day and regularly encounters a wide range of safety challenges, from power lines near work areas to tight spaces on small residential roofs. Because every job site is different, he emphasizes planning ahead before starting any work to make sure everyone, including himself, goes home safely at the end of the day.

What’s the most unusual safety hazard you’ve ever encountered?
I was working downtown Chicago on an extremely windy day with gusts up to 60 mph. While I was on the roof, construction debris from nearby high rises was blowing across the site. I even had to dodge pieces of flying insulation.

If you could invent a new safety gadget or tool, what would it be?
Boots that would not slip on any roof, no matter how much ice, snow, or rain is on it.

What’s your favorite safety slogan or motto?
“Plan ahead. No job is worth your life.”

What’s the most memorable safety lesson you’ve learned from your own experience?
Slow down and think through every move you make. Always be prepared for the worst-case scenario, even if the chances seem small.
