Flat Roof Installation for Commercial Properties in Madison, WI

If you're managing a large commercial building like warehouse, school, retail facility, or medical complex, selecting the appropriate flat roof system is more critical than ever. At Madison Roofing Company, we're commercial flat roof installation experts, combining durability, energy efficiency, and simplicity—custom-designed for Illinois weather and building regulations.

​

Flat roofs, unlike pitched roofs, provide a low-profile surface ideal for the installation of solar panels, skylights, and HVAC units while maintaining clean and modern exterior aesthetics. They're faster and cheaper to install on large commercial buildings—making them a favorite among property owners and developers in the region.

​

​

Why Flat Roofs Are Ideal for Commercial Buildings

Flat roofing systems are now the choice for buildings for several sound reasons. They use less material, cover more space efficiently, and provide safer access for maintenance. From logistics centers to apartment buildings, the flat roof is the choice for functionality as well as cost savings.

​

That said, a flat roof isn't completely flat. It’s designed with a slight slope to allow drainage and avoid water pooling. Without proper drainage, even the best flat roof material can suffer from early wear, mold, or hidden leaks.

 

That’s why our team handles everything—from slope engineering and insulation planning to membrane sealing and drainage system placement.

Flat Roofing Systems We Offer

No two structures are alike, and that's why we provide a variety of high-performance materials specific to your needs, environment, and budget.

• TPO Roofing: Light, reflective, and energy-efficient—TPO is a popular choice for companies concerned with cost savings and sustainability.

• EPDM Roofing: This rubber roofing material is tough, flexible, and ideal for large, low-slope buildings. It's also one of the simplest flat roof types to maintain in the long run.

• Modified Bitumen: Weather-resilient and reinforced, the best choice for high-traffic buildings on the roof.

• Built-Up Roofing (BUR): Time-tested and multi-layered, BUR is still the go-to solution for maximum water resistance.

• Fluid-Applied Membranes: Perfect for roofs with odd shapes or interference—this liquid coating seals leak-free and contours to your building.

• Metal Panel Roofing (Flat): Best for companies who want long-term ROI and very little maintenance, metal provides unmatchable durability and longevity.

​

We assist you in balancing factors such as reflectivity (cool roof coatings), cost per square foot, and compatibility with other rooftop elements such as solar infrastructure or skylights.

How Much Does It Cost to Install a Flat Roof?

The cost to install a new flat roof varies based on multiple parameters—size of the roof, material chosen, insulation required, difficulty of access, and drainage complexity. We also include rooftop equipment such as skylights, vents, or solar arrays that might impact installation.

​

At Madison Roofing, we don't go through generic numbers. We perform a complimentary on-site consultation and present you with a transparent proposal—so you know exactly what you're paying and why. While cheaper bids may cut corners on the grade of material or omit correct slope design, we focus on long-term performance and energy efficiency.
