Flat Roof FAQ

How long does a commercial flat roof typically last?

The lifespan of a commercial flat roof depends on several key factors, including the roofing system, installation quality, climate, foot traffic, and most importantly, ongoing maintenance.

With proper care, many flat roof systems can last 20 to 30 years or longer. Routine inspections, drain cleaning, minor repairs, and preventive maintenance can significantly extend roof life and help catch small issues before they become costly problems.

It’s also important to remember that many material warranties require routine maintenance and documentation to remain valid. Skipping regular care can shorten the life of the roof and potentially put warranty coverage at risk.

The reality is simple: maintenance plays a major role in maximizing roof life and protecting your investment.

If you want to get the most years out of your roof, check out our preventive maintenance packages on our website or call 847-255-3600 to discuss the best plan for your building.

Myth: Roof repairs always mean major disruption.

Truth: Many commercial roof repairs can be completed with minimal impact to building operations.

One of the biggest concerns building owners and facility teams have is downtime. The good news is that many commercial roofing repairs can be carefully planned and phased to keep your business running smoothly.
With the right crew, clear communication, and experienced project management, repairs can often be completed around daily operations, helping reduce disruption for employees, customers, and tenants.
The key is catching issues early, before a small repair turns into a larger project.

A proactive repair today can help avoid a much bigger interruption tomorrow.

Flat Roof FAQ

What causes ponding water on a flat roof?

Ponding water is typically caused by blocked drains, clogged scuppers, or low areas in the roof that prevent proper drainage. When water sits on the roof for extended periods, it can accelerate membrane wear, stress seams, and increase the risk of leaks.

Left unaddressed, what starts as a minor drainage issue can turn into costly repairs or premature roof failure.

Routine inspections and preventive maintenance are key to keeping water moving and protecting the long-term performance of your roof.

If you’re noticing standing water on your roof, it may be time for a professional assessment.

Is foot traffic bad for flat roofs?

Uncontrolled foot traffic can damage roofing membranes and seams. Over time, this can lead to wear, punctures, and leaks. Walk pads and designated pathways help protect the roof surface and extend its service life.

Not sure if your roof is properly protected? O’Hara’s Son Roofing Company (OSR) can inspect your roof, provide routine preventative maintenance, and install walk pads where needed to help reduce damage and extend performance.

Myth: A new roof does not need maintenance.
Truth: Even new commercial roofs require routine inspections.

Many building owners assume a new roof means years of worry-free performance. While a properly installed system provides long-term protection, regular inspections are still essential.

Routine maintenance helps:
• Identify minor issues before they turn into costly repairs
• Keep drainage systems clear and functioning properly
• Protect manufacturer warranty requirements
• Extend the overall life of the roofing system

A new roof is an investment. Ongoing care ensures you get the full value from it.
