Expert Commercial Roof Inspections
Why Regular Commercial Roof Inspections Matter
Ensuring the Best Outcome For Your Roof
Commercial roofs face constant aging, use, and even exposure to the elements, which can lead to significant wear and tear over time. Regular inspections are a critical part of property maintenance, as they allow for the early detection of small issues before they escalate into costly repairs.
Addressing these problems early on, before they become major problems, not only helps prevent structural damage but also minimizes business disruptions, meaning your business can continue daily operations uninterrupted. Additionally, routine inspections can extend the lifespan of your roofing system, saving you money in the long term by reducing the need for premature roof replacements – starting with knowing how to find a leak’s source before it spreads.
At Great Lakes Commercial Roofing, we take pride in providing a thorough and detailed inspection process, guided by years of experience in the commercial roofing industry. Our expert team is dedicated to helping you maintain a durable, reliable roof that protects your property and investments for years to come.
Routine inspections are incredibly important when it comes to maintaining the integrity and longevity of large facilities, industrial complexes, and aging roofs. Without proper monitoring, issues like water intrusion, membrane damage, and inadequate drainage can rapidly escalate, leading to costly repairs and potential operational disruptions.
Our team takes the guesswork out of roof care by conducting thorough inspections and providing detailed reports after every visit. Each report includes a comprehensive assessment of your roof’s current condition, as well as actionable recommendations tailored to your specific needs. Whether you’re planning a roof coating, scheduling routine maintenance, or considering a full commercial roof replacement, we make sure that you have all the information required to make well-informed decisions.
By addressing concerns proactively and with expert evaluation at every step, we help safeguard your investment while minimizing risks, so your facility stays secure and functional for years to come.
What Our Commercial Roof Inspection Covers
Our inspections go far beyond a quick glance from the ground—we take a deep dive into the health of your entire roofing system. Every inspection includes a detailed evaluation of membrane condition, flashing, seams, fasteners, penetrations, drainage systems, and any visible signs of structural stress or damage. We know that commercial roofs aren’t one-size-fits-all, so we tailor our process depending on the material and system in place.
Whether your building has a flat EPDM roof, a sloped metal system, or a heat-welded TPO or PVC membrane, our trained experts know exactly what to look for. We also factor in your building’s location, age, and maintenance history to provide the most accurate insights possible. When you work with Great Lakes Commercial Roofing, you get more than a checklist—you get clarity, protection, and peace of mind.
A thorough roof inspection should do more than point out surface-level wear—it should reveal what’s really going on beneath your roofing system. That’s why we go the extra mile to identify hidden vulnerabilities such as poor insulation, ponding water, ventilation issues, and early signs of leaks – including the risks of persistent ponding water. These problems often go unnoticed until it’s too late, costing business owners thousands.
Our inspectors use advanced techniques, clear photo documentation, and detailed written assessments so you know exactly what’s happening up there. No guesswork, no gray areas—just straightforward information you can act on. Our team meets rigorous industry standards and undergoes continuous training to stay on top of the latest materials and inspection protocols. We’re also proud to be a GAF PlatinumElite™ Commercial Contractor, a title that reflects our commitment to delivering top-tier service and long-term roofing solutions.
When it comes to protecting your roof, we don’t cut corners—we cover them.
Signs You May Need a Roof Inspection Soon
If your commercial roof is showing signs of wear, don’t wait to take action. Cracks, leaks, or pooling water could indicate underlying issues that may worsen over time. Addressing these symptoms promptly can prevent costly repairs, extend your roof’s lifespan, and ensure the safety and functionality of your building:
- Water stains on interior ceilings
- Rising HVAC or energy costs
- Visible cracks or splits
- Blistering or bubbling membrane
- Standing water after rain
These signs often mean your roofing system is compromised or underperforming, and addressing them promptly is vital. Cracks, leaks, or loose shingles may seem minor now, but frequent flat roof issues like these can quickly escalate, leading to costly structural damage. Catching problems early can save you thousands in future repairs and give you peace of mind.
Even if you’re not spotting visible damage, regular roof inspections are crucial to maintaining a safe and efficient system. Experts recommend scheduling annual or biannual inspections to ensure your roof stays in top shape. This is especially important before and after severe seasonal weather, anything from the heavy winter storms to blazing summer heat, which can accelerate wear and tear.
A well-maintained roof not only protects your home but also enhances its energy efficiency and longevity. Remember, preventative care is always more affordable and effective than an emergency roof replacement. Don’t wait—act now!

E Frogwell
When it comes to a company that will get the job done right you have to go with Great Lakes Commercial Roofing. Zac is easy to work with and very knowledgeable about many different products and options. Don’t make the mistake I did and call a contractor that is mainly a residential roofer to look at your industrial roof unless you like wasting money
Tom Havacheck
Great company to work with! I have a building in Pennsylvania but live in another state. My roof was leaking and Zac was sent out and did the inspection on the roof. When he was at the building he called and sent me a link to live pictures
Jason Bakus
These guys are awsome. Great job from start to finish. Did our large commercial catering hall. Always available if we have a question or concern. Roof looks great and best of all. No more leeks. Defiantly recommend

Barb Goliad
I called Great Lakes Commercial Roofing to come check out my building. I had a company put silicone roof coating on it 5 years ago and since day one it never stopped the leaking problems, the other company came out 5 times to “fix the problem” but never did. Zac came out and evaluated my problem and gave me a ton of information on the best solution to fix the problem.
