Commercial Roofing & Flat Roofing

MN Roofing & Construction provides professional commercial and flat roofing services for businesses, multifamily properties, and large facilities across Central Ohio. From EPDM and TPO systems to metal roofing, we deliver long-lasting solutions with disciplined installation, manufacturer-backed warranties, and pricing that consistently comes in lower than competitors, without cutting corners.

Commercial Roofing Solutions

Commercial roofing problems rarely arrive at a convenient time. Property owners and managers are often forced to make decisions under pressure, whether they are dealing with an active leak or evaluating a roof that has been repaired repeatedly over the years. One of the biggest challenges is knowing when another repair makes sense and when a full roof replacement is the smarter, long-term solution. That decision affects budgets, operations, and the building’s future reliability, making the choice of contractor especially important.

Large commercial roofs require coordination, experience, and a clear plan that minimizes disruption. MN Roofing is structured to manage both targeted repairs and full commercial roof replacements without interfering with tenants, customers, or daily operations. We assess the roof’s condition, explain realistic options, and phase work when appropriate so building use can continue safely and predictably throughout the project.

Commercial roofing proposals can vary widely, even when the materials and warranty categories appear similar, making it difficult to compare options with confidence. MN Roofing takes a disciplined, transparent approach to estimating by clearly outlining repair versus replacement scenarios based on roof condition, system type, warranty level, and long-term performance. Our crews are certified across multiple commercial and flat roofing systems, and our work always meets municipal and manufacturer inspection requirements. The result is a commercial roofing partner focused on durable outcomes, operational continuity, and pricing you can clearly understand and justify.

EPDM, TPO, Metal, and Rolled Roofing Systems

Most commercial roofing projects fall into a few proven system types, with EPDM (rubber) and TPO membranes accounting for the majority of flat roof installations. These systems are widely used because they deliver dependable performance, strong weather resistance, and predictable lifespans when properly installed.

MN Roofing also installs rolled roofing systems with rubber-based membranes that may include asphalt or finished coatings, depending on the application, as well as commercial metal roofing, which offers the longest service life available for commercial buildings.

Roof Systems Duration Comparison 

  • Metal Roofing: 40+ year lifespan 
  • EPDM & Rolled Roofing: 20–25 years
  • TPO Roofing: 20–25 years

MN Roofing installs all roofing systems using manufacturer-approved materials and methods, ensuring full warranty eligibility rather than limited coverage caused by installation shortcuts.

Quality-Controlled Installation with Verified Performance

The success of a commercial roofing system ultimately depends on workmanship. MN Roofing differentiates itself through disciplined installation standards and rigorous verification at every stage of the project.

Every commercial roof we install undergoes multiple layers of inspection. Projects are reviewed by local or county building inspectors and independently evaluated by the roofing system manufacturer. Manufacturer inspections are comprehensive, covering seams, penetrations, flashing details, and overall system integrity. On warrantied projects, our installations consistently achieve workmanship scores in the 99–100% range. Those scores also apply to our large commercial roofs, which have hundreds or thousands of penetrations.

This level of oversight ensures long-term performance and protects the building owner’s investment. As a locally owned and operated company, MN Roofing maintains hands-on quality control throughout the project. Ownership remains directly involved in execution and accountability, rather than being removed behind sales teams or regional management structures.

Clear Diagnosis, Effective Repairs, and Honest Recommendations

Roof leaks require quick action, but the right solution starts with an accurate diagnosis. MN Roofing carefully inspects flat roofing systems for common failure points, including water pooling, seam separation, and compromised penetrations around HVAC units, piping, skylights, and vents. Many temporary or DIY fixes fall short because rubber roofing systems demand precise surface preparation and application methods. When those steps are missed, patches often fail and can worsen the underlying issue.

If a roof is within its usable service life, we focus on targeted, professional repairs that restore performance and extend longevity. When materials begin to crack, seams separate, water pools, or the system as a whole is nearing the end of its lifespan, we clearly explain why replacement may be the more practical and cost-effective choice. Our approach is simple. We provide honest recommendations and resolve problems correctly the first time, without pressure or unnecessary upselling.

Our Transparent Process from Inspection to Completion

Inspection – We begin by thoroughly evaluating the roof, including insulation, drainage, seams, and penetrations.

Documentation – All findings are captured with photos and video to ensure full transparency.

Quote – A detailed estimate is provided, clearly outlining system type, warranty level, and repair or replacement options.

Scheduling – Projects are planned with consideration of size, urgency, and building access to minimize disruption.

Completion – Skilled crews execute the work, followed by manufacturer and internal inspections, with a final cleanup to leave your property in top condition.

Project timelines vary. Smaller flat roof repairs can often be completed in a few days, while larger or more complex installations may take several weeks, depending on roof size and the number of penetrations.

What causes flat roofs to fail?

Most roof failures result from aging materials or improper installation rather than weather alone. Even high-quality systems can develop problems over time if seams, penetrations, or underlying layers were not installed correctly, or if routine maintenance was neglected. Proper installation and timely repairs are key to extending the life of any roof.

How do you improve flat roof drainage?

Effective flat roof drainage starts with proper design and precise installation. We use pre-sloped insulation systems that are carefully shaped to channel water toward drains, scuppers, or gutters, preventing pooling and reducing the risk of leaks. Combined with correctly positioned drains and attention to seams and penetrations, this approach ensures water flows efficiently off the roof, protecting the building and extending the roof’s lifespan.

What roofing system lasts the longest?

For commercial buildings, metal roofing provides the longest lifespan, often exceeding 40 years in Ohio’s climate. Its durability, resistance to weather, and low maintenance requirements make it a long-term investment, especially when installed with manufacturer-approved materials and methods.

Are warranties included?

Yes. All of our roofing systems are installed with manufacturer-approved materials and methods that qualify for full, backed warranties. This ensures your investment is protected and gives you confidence in the long-term performance of your roof.

How do you guarantee quality?

Every commercial roof we install undergoes multiple inspections to ensure lasting performance. Local building inspectors review the work for code compliance, and the roofing system manufacturer conducts a thorough evaluation of seams, penetrations, and overall installation. This dual inspection process guarantees the highest workmanship standards and protects your investment.

Ok, so I’ve hired over 15 contractors in the past 3 weeks and spent about $45k polishing this mid century modern house we just bought. My interaction with Craig from M&N Roofing has been the best contractor experience I’ve ever had working with one.
