Is a flat roof the right choice for your home?

Flat roofs are a popular choice for both residential and commercial buildings due to their modern aesthetic, efficient use of space, and cost-effectiveness. Unlike traditional sloped roofs, flat roofs provide additional usable space for HVAC systems, solar panels, rooftop patios, or green roofing solutions. While they offer several advantages, they also require specific materials and maintenance to ensure long-term durability and performance.

Cost Modifiers

Flat Roof Systems Built for Minnesota Weather and Modern Living.

The most important factors in determining the cost of the repair or replacement of flat or low pitch roofs in Minneapolis are roof size, complexity and height. Labor can vary greatly because different materials require different installation techniques. Flat roofs come in a variety of colors and thicknesses making the potential cost range from the low to high end quite broad. For example, a .45mil standard epdm (rubber) will be on the cheap end where a .90mil reinforced epdm will cost a fair amount more. Frequently we are tying flat roof systems into integrated drainage systems such as scuppers and open-face down spouts. These costs need to be included in calculating the overall cost of your project.

Flat Roof Replacement Costs

When estimating the cost of a flat roofing project, several key factors come into play.

Let’s say you have a typical 20 square, 1/12 pitch Flat roof that needs replacing. What is the potential cost for such a roof? Answer, $48,000 (20 x $2,400). This assumes you use a quality grade flat roof material with the recommended underlayment, which realistically will cost $475 to $800 per square. There is a wide cost spectrum among the flat roof products available so budget is a key consideration in determining what to use. If we are repairing your flat roof the existing material will be matched as closely as possible. Roof complexity and quantity of penetrations like skylights and plumbing stacks will also play a role in the cost to replace your flat roof.

Roofing Repair

Over time, flat roofs may require repairs due to weather exposure, aging, or improper installation. Common flat roof repairs include sealing leaks caused by membrane damage or deteriorated flashing, replacing damaged or blistered sections, reinforcing seams and fasteners, and applying new protective coatings to extend the roof’s lifespan. Regular inspections and proactive maintenance help prevent minor issues from becoming costly problems. If water pooling, leaks, or visible damage occur, it’s essential to address these concerns promptly to maintain the roof’s integrity and performance.

As an licensed Architect it has always been a challenge to find a contractor that understands the importance of detail to the success of any project. Steve Kuhl has participated in design solutions and anticipated construction challenges before they happen. Steve has educated me on new construction systems and products for our specific projects. Kuhl’s has the tools, experience and creativity to take on complicated projects that need special attention. We have used Kuhl for additions to our personal residence in Minnetonka and are considering a major remodeling of which I would not hesitate to bring Steve early into the design process which I know will benefit the construction process.

Wondering if a flat roof is the right choice for your home?

Flat roofing may not be for you if


  • Drainage Issues: Flat roofs do not shed water as efficiently as sloped roofs, making proper drainage systems essential to prevent pooling and leaks.
  • Weight Limitations: Flat roofs must be designed to handle additional weight loads, especially in regions with heavy snowfall or frequent rain.
  • Limited options: There are fewer material options for flat roof systems, including EPDM and TPO as the industry leaders.
